Safety Instructions, Warnings, and Notes
2. Safety Instructions, Warnings, and Notes
Index of this chapter: 2.1 Safety Instructions 2.2 Warnings 2.3 Notes · Where necessary, measure the waveforms and voltages with (D) and without (E) aerial signal. Measure the voltages in the power supply section both in normal operation (G) and in stand-by (F). These values are indicated by means of the appropriate symbols.
2.1
Safety Instructions
Safety regulations require the following during a repair: · Connect the set to the Mains/AC Power via an isolation transformer (> 800 VA). · Replace safety components, indicated by the symbol h, only by components identical to the original ones. Any other component substitution (other than original type) may increase risk of fire or electrical shock hazard. Safety regulations require that after a repair, the set must be returned in its original condition. Pay in particular attention to the following points: · Route the wire trees correctly and fix them with the mounted cable clamps. · Check the insulation of the Mains/AC Power lead for external damage. · Check the strain relief of the Mains/AC Power cord for proper function. · Check the electrical DC resistance between the Mains/AC Power plug and the secondary side (only for sets that have a Mains/AC Power isolated power supply): 1. Unplug the Mains/AC Power cord and connect a wire between the two pins of the Mains/AC Power plug. 2. Set the Mains/AC Power switch to the "on" position (keep the Mains/AC Power cord unplugged!). 3. Measure the resistance value between the pins of the Mains/AC Power plug and the metal shielding of the tuner or the aerial connection on the set. The reading should be between 4.5 M and 12 M. 4. Switch "off" the set, and remove the wire between the two pins of the Mains/AC Power plug. · Check the cabinet for defects, to prevent touching of any inner parts by the customer.
2.3.2
Schematic Notes · All resistor values are in ohms, and the value multiplier is often used to indicate the decimal point location (e.g. 2K2 indicates 2.2 k). Resistor values with no multiplier may be indicated with either an "E" or an "R" (e.g. 220E or 220R indicates 220 ). All capacitor values are given in micro-farads ( = × 10-6), nano-farads (n = × 10-9), or pico-farads (p = × 10-12). Capacitor values may also use the value multiplier as the decimal point indication (e.g. 2p2 indicates 2.2 pF). An "asterisk" (*) indicates component usage varies. Refer to the diversity tables for the correct values. The correct component values are listed in the Spare Parts List. Therefore, always check this list when there is any doubt.

BGA (Ball Grid Array) ICs Introduction For more information on how to handle BGA devices, visit this URL: www.atyourservice.ce.philips.com (needs subscription, not available for all regions). After login, select "Magazine", then go to "Repair downloads". Here you will find Information on how to deal with BGA-ICs. BGA Temperature Profiles For BGA-ICs, you must use the correct temperature-profile, which is coupled to the 12NC. For an overview of these profiles, visit the website www.atyourservice.ce.philips.com (needs subscription, but is not available for all regions) You will find this and more technical information within the "Magazine", chapter "Repair downloads". For additional questions please contact your local repair help desk.
2.2
Warnings
· All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD w). Careless handling during repair can reduce life drastically. Make sure that, during repair, you are connected with the same potential as the mass of the set by a wristband with resistance. Keep components and tools also at this same potential. Be careful during measurements in the high voltage section. Never replace modules or other components while the unit is switched "on". When you align the set, use plastic rather than metal tools. This will prevent any short circuits and the danger of a circuit becoming unstable. 2.3.4
Lead-free Soldering Due to lead-free technology some rules have to be respected by the workshop during a repair: · Use only lead-free soldering tin Philips SAC305 with order code 0622 149 00106. If lead-free solder paste is required, please contact the manufacturer of your soldering equipment. In general, use of solder paste within workshops should be avoided because paste is not easy to store and to handle. · Use only adequate solder tools applicable for lead-free soldering tin. The solder tool must be able: To reach a solder-tip temperature of at least 400°C. To stabilize the adjusted temperature at the solder-tip. To exchange solder-tips for different applications. · Adjust your solder tool so that a temperature of around 360°C - 380°C is reached and stabilized at the solder joint. Heating time of the solder-joint should not exceed ~ 4 sec. Avoid temperatures above 400°C, otherwise wear-out of tips will increase drastically and flux-fluid will be destroyed. To avoid wear-out of tips, switch "off" unused equipment or reduce heat. · Mix of lead-free soldering tin/parts with leaded soldering tin/parts is possible but PHILIPS recommends strongly to avoid mixed regimes. If this cannot be avoided, carefully clear the solder-joint from old tin and re-solder with new tin.

2.3.1
Notes
General · Measure the voltages and waveforms with regard to the chassis (= tuner) ground (H), or hot ground (I), depending on the tested area of circuitry. The voltages and waveforms shown in the diagrams are indicative. Measure them in the Service Default Mode (see chapter 5) with a colour bar signal and stereo sound (L: 3 kHz, R: 1 kHz unless stated otherwise) and picture carrier at 475.25 MHz for PAL, or 61.25 MHz for NTSC (channel 3).
Directions for Use
2.3.5 Alternative BOM identification
MODEL
Q522.3E LA

EN 7
: 32PF9968/10
It should be noted that on the European Service website, "Alternative BOM" is referred to as "Design variant".
PROD.NO: AG 1A0617 000001
MADE IN BELGIUM 220-240V ~ 50/60Hz 128W VHF+S+H+UHF
The third digit in the serial number (example: AG2B0335000001) indicates the number of the alternative B.O.M. (Bill Of Materials) that has been used for producing the specific TV set. In general, it is possible that the same TV model on the market is produced with e.g. two different types of displays, coming from two different suppliers. This will then result in sets which have the same CTN (Commercial Type Number; e.g. 28PW9515/12) but which have a different B.O.M. number. By looking at the third digit of the serial number, one can identify which B.O.M. is used for the TV set he is working with. If the third digit of the serial number contains the number "1" (example: AG1B033500001), then the TV set has been manufactured according to B.O.M. number 1. If the third digit is a "2" (example: AG2B0335000001), then the set has been produced according to B.O.M. no. 2. This is important for ordering the correct spare parts! For the third digit, the numbers 1...9 and the characters A...Z can be used, so in total: 9 plus 26= 35 different B.O.M.s can be indicated by the third digit of the serial number. Identification: The bottom line of a type plate gives a 14-digit serial number. Digits 1 and 2 refer to the production centre (e.g. AG is Bruges), digit 3 refers to the B.O.M. code, digit 4 refers to the Service version change code, digits 5 and 6 refer to the production year, and digits 7 and 8 refer to production week (in example below it is 2006 week 17). The 6 last digits contain the serial number.

Board Level Repair (BLR) or Component Level Repair (CLR) If a board is defective, consult your repair procedure to decide if the board has to be exchanged or if it should be repaired on component level. If your repair procedure says the board should be exchanged completely, do not solder on the defective board. Otherwise, it cannot be returned to the O.E.M. supplier for back charging!
2.3.7
Practical Service Precautions · It makes sense to avoid exposure to electrical shock. While some sources are expected to have a possible dangerous impact, others of quite high potential are of limited current and are sometimes held in less regard. Always respect voltages. While some may not be dangerous in themselves, they can cause unexpected reactions that are best avoided. Before reaching into a powered TV set, it is best to test the high voltage insulation. It is easy to do, and is a good service precaution.

Test Points
As most signals are digital, it will be difficult to measure waveforms with a standard oscilloscope. However, several key ICs are capable of generating test patterns, which can be controlled via ComPair. In this way it is possible to determine which part is defective. Perform measurements under the following conditions: · Service Default Mode. · Video: Colour bar signal. · Audio: 3 kHz left, 1 kHz right.
How to Activate SDM For this chassis there are two kinds of SDM: an analogue SDM and a digital SDM. Tuning will happen according table "SDM Default Settings". · Analogue SDM: use the standard RC-transmitter and key in the code "062596", directly followed by the "MENU" button. Note: It is possible that, together with the SDM, the main menu will appear. To switch it "off", push the "MENU" button again. · Digital SDM: use the standard RC-transmitter and key in the code "062593", directly followed by the "MENU" button. Note: It is possible that, together with the SDM, the main menu will appear. To switch it "off", push the "MENU" button again. · Analogue SDM can also be activated by shorting for a moment the two solder pads [1] (see figure "Service mode pads") on the SSB, with the indication "SDM". Activation can be performed in all modes, except when the set has a problem with the Stand-by Processor.
5.2
Service Modes
Service Default mode (SDM) and Service Alignment Mode (SAM) offers several features for the service technician, while the Customer Service Mode (CSM) is used for communication between the call centre and the customer. This chassis also offers the option of using ComPair, a hardware interface between a computer and the TV chassis.

After activating SAM with this method a service warning will appear on the screen, you can continue by pressing the red button on the RC. Contents of SAM: · Hardware Info. A. SW Version. Displays the software version of the main software (example: Q522E-1.2.3.4 = AAAAB_X.Y.W.Z). · AAAA= the chassis name. · B= the region: A= AP, E= EU, L= LatAm, U = US. For AP sets it is possible that the Europe software version is used. · X.Y.W.Z= the software version, where X is the main version number (different numbers are not compatible with one another) and Y.W.Z is the sub version number (a higher number is always compatible with a lower number). B. SBY PROC Version. Displays the software version of the stand-by processor. C. Production Code. Displays the production code of the TV, this is the serial number as printed on the back of the TV set. Note that if an NVM is replaced or is initialized after corruption, this production code has to be re-written to NVM. ComPair will foresee in a possibility to do this. · Operation Hours. Displays the accumulated total of operation hours (not the stand-by hours). Every time the TV is switched "on/off", 0.5 hours is added to this number. · Errors (followed by maximal 10 errors). The most recent error is displayed at the upper left (for an error explanation see paragraph "Error Codes"). · Reset Error Buffer. When you press "cursor right" (or the "OK button) and then the "OK" button, the error buffer is reset. · Alignments. This will activate the "ALIGNMENTS" submenu. For more information regarding alignment, see chapter 8 "Alignments". · Dealer Options. Extra features for the dealers. · Options. Extra features for Service. For more info regarding option codes, see chapter 8 "Alignments". Note that if you change the option code numbers, you have to confirm your changes with the "OK" button before you store the options. Otherwise you will loose your changes. · Initialise NVM. The moment the processor recognizes a corrupted NVM, the "initialize NVM" line will be highlighted. Now, you can do two things (dependent of the service instructions at that moment): Save the content of the NVM via ComPair for development analysis, before initializing. This will give the Service department an extra possibility for diagnosis (e.g. when Development asks for this). Initialize the NVM. Note: When you have a corrupted NVM, or you have replaced the NVM, there is a high possibility that you will not have picture any more because your display code is not correct. So, before you can initialize your NVM via the SAM, you need to have a picture and therefore you need the correct display option. Refer to chapter 8 for details. To adapt this option, you can use ComPair (the correct HEX values for the options can be found in chapter 8 "Alignments") or a method via a standard RC (described below).

Changing the display option via a standard RC: Key in the code "062598" directly followed by the "MENU" button and "XXX", where XXX is the 3 digit decimal display code (see table "Option code overview" in chapter 8 "Alignments", or sticker on the side/bottom of the cabinet). Make sure to key in all three digits, also the leading zero's. If the above action is successful, the front LED will go out as an indication that the RC sequence was correct. After the display option is changed in the NVM, the TV will go to the Stand-by mode. If the NVM was corrupted or empty before this action, it will be initialized first (loaded with default values). This initializing can take up to 20 seconds.

The items are "Channel list", "Personal settings", "Option codes", "Display-related alignments", "History list" and "Skins List". The upload of the "Skis List" will be supported in newer versions of the TV software, but won't be available in all versions. It however will be a selectable item, but activating will not write data to the USB stick. Remark: Please note down a the list of available Themes in the set before doing a software upgrade. These Themes can be added after the upgrade by downloading them from http://www.philips.com/flavors. To upload the settings you have to select each item separately, press "cursor right" (or the "OK button), confirm with "OK" and wait until "Done" appears. In case the download to the USB stick was not successful "Failure" will appear. In this case, check if the USB stick is connected properly and if the directory "repair" is present in the root of the USB stick. Now the settings are stored onto your USB stick and can be used to download onto another TV or other SSB. Up loading is of course only possible if the software is running and if you have a picture. This method is created to be able to save the customer's TV settings and to store them into another SSB. Download from USB. To download several settings from the USB stick to the TV. Same way of working as with up loading. To make sure that the download of the channel list from USB to the TV is executed properly, it is necessary to restart the TV and tune to a valid preset if necessary.

How to Navigate · In SAM, you can select the menu items with the "CURSOR UP/DOWN" key on the RC-transmitter. The selected item will be highlighted. When not all menu items fit on the screen, move the "CURSOR UP/DOWN" key to display the next/previous menu items. · With the "CURSOR LEFT/RIGHT" keys, it is possible to: (De) activate the selected menu item. (De) activate the selected sub menu. · With the "OK" key, it is possible to activate the selected action. How to Exit SAM Use one of the following methods: · Press the "MENU" button on the RC-transmitter. · Switch the set to STAND-BY via the RC-transmitter. 5.2.3 Customer Service Mode (CSM) Purpose When a customer is having problems with his TV-set, he can call his dealer or the Customer Help desk. The service technician can then ask the customer to activate the CSM, in order to identify the status of the set. Now, the service technician can judge the severity of the complaint. In many cases, he can advise the customer how to solve the problem, or he can decide if it is necessary to visit the customer. The CSM is a read only mode; therefore, modifications in this mode are not possible. When in this chassis CSM is activated, a colour bar test pattern will be visible for 5 seconds. This test pattern is generated by the Pacific3. So if you see this test pattern you can determine that the back end video chain (Pacific3, LVDS, and display) of the SSB is working. In case of a set with DFI panel, an extra test picture is generated. So you will see the Pacific3 test picture for 3 seconds and then the DFI EPLD test picture for another 3 seconds. With this extra test picture you can determine if the DFI board is working properly. Also new in this chassis: when you activate CSM and there is a USB stick connected to the TV, the software will dump the complete CSM content to the USB stick. The file (Csm*.txt) will be saved in the root of your USB stick. This information can be handy if you do not have picture. Another new item in this chassis is when CSM is activated, the complete error-buffer content will be shown via the blinking LED procedure. How to Activate CSM Key in the code "123654" via the standard RC transmitter. Note: Activation of the CSM is only possible if there is no (user) menu on the screen! How to Navigate By means of the "CURSOR-DOWN/UP" knob on the RCtransmitter, you can navigate through the menus. Contents of CSM · Set Type. This information is very helpful for a help desk/ workshop as reference for further diagnosis. In this way, it is not necessary for the customer to look at the rear of the TV-set. Note that if an NVM is replaced or is initialized after corruption, this set type has to be re-written to NVM. ComPair will foresee in a possibility to do this. · Production Code. Displays the production code (the serial number) of the TV. Note that if an NVM is replaced or is initialized after corruption, this production code has to be re-written to NVM. ComPair will foresee a in possibility to do this. · Code 1. Gives the last five errors of the error buffer. As soon as the built-in diagnose software has detected an error, the buffer is adapted. The last occurred error is displayed on the leftmost position. Each error code is displayed as a 2-digit number. When less than 10 errors

Q522.3E LA
Service Modes, Error Codes, and Fault Finding
due to over voltage. It is recommended to measure first the FET 7U08 on short-circuit before activating SDM via the service pads. When the TV is in protection state due to an error detected by main software (MIPS protection) and SDM is activated via short-cutting the service pads on the SSB, the TV starts up and ignores the error. In this chassis, only error "63" (power-ok) is a MIPS protection and already displays the failure via blinking LED. The abbreviations "SP" and "MP" in the figures stand for: · SP: protection or error detected by the Stand-by Processor. · MP: protection or error detected by the MIPS Main Processor.
Stepwise Start-up
There are two possible situations: one for protections detected by the stand-by software and one for protections detected by the main software. When the TV is in a protection state due to an error detected by stand-by software (and thus blinking an error) and SDM is activated via short-circuiting the pins on the SSB, the TV starts up until it reaches the situation just before protection. So, this is a kind of automatic stepwise start-up. In combination with the start-up diagrams below, you can see which supplies are present at a certain moment. Important to know is, that if e.g. the 3V3 detection fails (and thus error 8 is blinking) and the TV is restarted via SDM, the Stand-by Processor will enable the 3V3, but will not go to protection now. The TV will stay in this situation until it is reset (Mains/AC Power supply interrupted). Caution: in case the start up in this mode with a faulty FET 7U08 is done, you can destroy all ICs supplied by the +3V3,

Constraints taken into account:
- Display may only be started when valid LVDS output clock can be delivered by the AVC . - Between 5 and 50 ms after power is supplied, display should receive valid LVDS clock . - Backlight Control PWM output should always keep low until LVDS power is supplied . - Minimum wait time to switch "on" the lamp after power up is 200ms. - To have a reliable operation of the backlight, the backlight should be driven with a PWM duty cycle of 100% during the first 2 seconds. Only after this first 2 seconds, the PWM may be set to the required output level (Note that the PWM output should be present before the backlight is switched on). To minimize the artefacts, the picture should only be unblanked after this first second. action holder: AVC action holder: St-by autonomous action
Semi Standby
The assumption here is that a fast toggle (<2s) can only happen during ON ->SEMI ->ON. In these states, the AVC is still active and can provide the 2s delay. If the transition ON ->SEMI>STBY->SEMI->ON can be made in less than 2s, we have to delay the semi->stby transition until the requirement is met . Wait until previous on-state is left more than 2 seconds ago. (to prevent LCD display problems)

ComPair helps you to quickly get an understanding on how to repair the chassis in a short and effective way. 2. ComPair allows very detailed diagnostics and is therefore capable of accurately indicating problem areas. You do not have to know anything about I2C or UART commands yourself, because ComPair takes care of this. 3. ComPair speeds up the repair time since it can automatically communicate with the chassis (when the uP is working) and all repair information is directly available. 4. ComPair features TV software upgrade possibilities. Specifications ComPair consists of a Windows based fault finding program and an interface box between PC and the (defective) product. The (new) ComPair II interface box is connected to the PC via an USB cable. For the TV chassis, the ComPair interface box and the TV communicate via a bi-directional cable via the service connector(s). How to Connect This is described in the ComPair chassis fault finding database.

Error Codes
Introduction The error code buffer contains all detected errors since the last time the buffer was erased. The buffer is written from left to right, new errors are logged at the left side, and all other errors shift one position to the right. When an error occurs, it is added to the list of errors, provided the list is not full. When an error occurs and the error buffer is full, then the new error is not added, and the error buffer stays intact (history is maintained). To prevent that an occasional error stays in the list forever, the error is removed from the list after more than 50 hrs. of operation. When multiple errors occur (errors occurred within a short time span), there is a high probability that there is some relation between them. Basically there are three kinds of errors: · Errors detected by the Stand-by software. These errors will always lead to protection and an automatic start of the blinking LED for the concerned error (see paragraph "The Blinking LED Procedure"). In these cases SDM can be used to start up (see chapter "Stepwise Start-up"). Note that it can take up to 90 seconds before the TV goes to protection and starts blinking the error (e.g. error 53). · Errors detected by main software that lead to protection. In this case the TV will go to protection and the front LED should also blink the concerned error. See also paragraph "Error Codes" -> "Error Buffer" -> "Extra Info". For this chassis only error 63 is a protection error detected by main software. · Errors detected by main software that do not lead to protection. In this case the error will be logged into the error buffer and can be read out via ComPair, via blinking LED method, or in case you have picture, via SAM.

How to Read the Error Buffer Use one of the following methods: · On screen via the SAM (only if you have a picture). E.g.: 00 00 00 00 00: No errors detected 06 00 00 00 00: Error code 6 is the last and only detected error 09 06 00 00 00: Error code 6 was first detected and error code 9 is the last detected error · Via the blinking LED procedure (when you have no picture). See next paragraph. · Via ComPair. · Via CSM. when CSM is activated the blinking LED procedure will start and the CSM content will be written to a USB stick (if present).

Figure 5-13 ComPair II interface connection Caution: The way of connection for this chassis is different compared to the other Q52x chassis! This chassis uses UART communication instead of RS232 which means that the voltage levels are different. When you connect this chassis with a ComPair RS232 cable, this might result in damaging the TV! Therefore, it is compulsory to use ComPair II interface together with the below mentioned Jack/Jack cable. How to Order ComPair II order codes: · ComPair II interface: 3122 785 91020. · The latest ComPair software can be found on the Philips Service website. · ComPair Jack/Jack cable: 3138 188 75051. Note: If you encounter any problems, contact your local support desk. 5.4.2 LVDS Tool Support of the LVDS Tool has been discontinued. 5.5.4

How to Clear the Error Buffer Use one of the following methods: · By activation of the "RESET ERROR BUFFER" command in the SAM menu. · With a normal RC, key in sequence "MUTE" followed by "062599" and "OK". · If the content of the error buffer has not changed for 50+ hours, it resets automatically. Error Buffer In case of non-intermittent faults, clear the error buffer before you begin the repair (before clearing the buffer, write down the content, as this history can give you significant information). This to ensure that old error codes are no longer present. If possible, check the entire contents of the error buffer. In some situations, an error code is only the result of another error

the DC/DC +3V3-STANDBY_+1V2-STANDBY (B02B) probably 1V2 STANDBY and 3V3 STANDBY under voltage cause the "DETECT1" (B04A) line activated. Error 9 (Supply fault). When this error occurs, the TV set shutdown in protection mode and follow with the Error blinking. This error will point to a hardware problem around the DC/DC 3V3_1V2 (B02A) probably the CLASS D amplifier output cause the "SUPPLY FAULT" (B10A) line activated. Error 23 (HDMI MUX). When this error occurs it means that there is a problem with the I2C communication towards the HDMI MUX IC AD8197. This error will point to a hardware problem around the digital IO HDMI MUX (B09). It is possible you will see error "23" logged in the error buffer. The best way for further diagnosis, is to use ComPair (e.g. read out the NVM content). Error 26 (Master IF). When this error occurs it means that there is a problem with the I2C communication towards the MASTER IF TDA9898. it is probably will be no picture and sound from tuner input. This error will point to a hardware problem around the Main Tuner (B03A) IF processing IC. It is possible you will see error "26" logged in the error buffer. Error 34 (Tuner). When this error occurs it means that there is a problem with the I2C communication towards the Tuner 1716. There probably will be no picture and sound from tuner input. This error will point to a hardware problem around the Main Tuner (B03A). As a side effect of error 34, it is possible that error 24 (no existing error) is also logged. Error 37 (Channel decoder). When this error occurs, there probably will be no picture and sound from tuner input. As a side effect of error 37 it is possible that error 4 (no existing error) is also logged. Error 53. This error will indicate that the PNX85xx has read his bootscript (if this would have failed, error 5 would blink) but initialization was never completed because of hardware problems (NAND flash, ...) or software initialization problems. Possible cause could be that there is no valid software loaded (try to upgrade to the latest main software version). Note that it can take up to 2 minutes before the TV starts blinking error 53.
code and not the actual cause (e.g., a fault in the protection detection circuitry can also lead to a protection). There are several mechanisms of error detection: · Via error bits in the status registers of ICs. · Via polling on I/O pins going to the stand-by processor. · Via sensing of analogue values on the stand-by processor or the PNX85xx. · Via a "not acknowledge" of an I2C communication. Take notice that some errors need more than 90 seconds before they start blinking or before they will be logged. So in case of problems wait 2 minutes from start-up onwards, and then check if the front LED is blinking or if an error is logged.

Extra Info · Rebooting. When a TV is constantly rebooting due to internal problems, most of the time no errors will be logged or blinked. This rebooting can be recognized via a ComPair interface and Hyperterminal (for Hyperterminal settings, see paragraph "Stand-by Software Upgrade"). You will see that the loggings which are generated by the main software keep continuing. In this case (rebooting) diagnose has to be done via ComPair. · Error 3 (I2C bus 3 blocked). When this error occurs, the TV will constantly reboot due to the blocked bus. The best way for further diagnosis here, is to use ComPair (e.g. read out the NVM content). Instead of error "3" it is possible you will see error "2" in the error buffer. · Error 5 (PNX85xx doesn't boot). When this error occurs, the TV main processor was not able to read his boot script. This error will point to a hardware problem around the PNX85xx (supplies not OK, PNX 85xx completely dead, I2C link between PNX and Stand-by Processor broken, etc...). When error 5 occurs it is also possible that I2C2 bus is blocked (NVM). I2C2 can be indicated in the schematics as follows: SCLUP-MIPS, SDA-UP-MIPS, SCL-SLAVE, SDA-SLAVE, SCL-2 or SDA-2. · Error 5 (PNX85xx doesn't boot). When this error occurs, the TV main processor was not able to read his boot script. This error will point to a hardware problem around the PNX85xx (supplies not OK, PNX 85xx completely dead, I2C link between PNX and Stand-by Processor broken, etc...). When error 5 occurs it is also possible that I2C2 bus is blocked (NVM). I2C2 can be indicated in the schematics as follows: SCLUP-MIPS, SDA-UP-MIPS, SCL-SLAVE, SDA-SLAVE, SCL-2 or SDA-2. · Error 6 (5V, 12V supply). When this error occurs, the TV set shutdown in protection mode and follow with the Error blinking.This error will point to a hardware problem around the DC/DC (B02C) probably 5V supply is under voltage cause the "PROT-DC" (B02C) line activated. Or another possibility is the 12V supply under voltage cause the "DETECT2" (B04A) line activated. · Error 8 (1V2, 3V3 supply).
