2.3
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). 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. The semiconductors indicated in the circuit diagram and in the parts lists, are interchangeable per position with the semiconductors in the unit, irrespective of the type indication on these semiconductors.
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 Mohm and 12 Mohm. 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 kohm). Resistor values with no multiplier may be indicated with either an "E" or an "R" (e.g. 220E or 220R indicates 220 ohm). All capacitor values are given in micro-farads (µ= x10-6), nano-farads (n= x10-9), or pico-farads (p= x10-12). 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.
·
· · · ·
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. Available ESD protection equipment: Complete kit ESD3 (small tablemat, wristband, connection box, extension cable and earth cable) 4822 310 10671. Wristband tester 4822 344 13999. 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.
2.3.3
Rework on BGA (Ball Grid Array) ICs General Although (LF)BGA assembly yields are very high, there may still be a requirement for component rework. By rework, we mean the process of removing the component from the PWB and replacing it with a new component. If an (LF)BGA is removed from a PWB, the solder balls of the component are deformed drastically so the removed (LF)BGA has to be discarded. Device Removal As is the case with any component that, is being removed, it is essential when removing an (LF)BGA, that the board, tracks, solder lands, or surrounding components are not damaged. To remove an (LF)BGA, the board must be uniformly heated to a temperature close to the reflow soldering temperature. A uniform temperature reduces the risk of warping the PWB. To do this, we recommend that the board is heated until it is certain that all the joints are molten. Then carefully pull the component off the board with a vacuum nozzle. For the appropriate temperature profiles, see the IC data sheet. Area Preparation When the component has been removed, the vacant IC area must be cleaned before replacing the (LF)BGA. Removing an IC often leaves varying amounts of solder on the mounting lands. This excessive solder can be removed with either a solder sucker or solder wick. The remaining flux can be removed with a brush and cleaning agent.
· · ·
Safety Instructions, Warnings, and Notes
After the board is properly cleaned and inspected, apply flux on the solder lands and on the connection balls of the (LF)BGA. Note: Do not apply solder paste, as this has been shown to result in problems during re-soldering. Device Replacement The last step in the repair process is to solder the new component on the board. Ideally, the (LF)BGA should be aligned under a microscope or magnifying glass. If this is not possible, try to align the (LF)BGA with any board markers. So as not to damage neighbouring components, it may be necessary to reduce some temperatures and times. More Information 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 "Workshop Information". Here you will find Information on how to deal with BGA-ICs. 2.3.4 Lead-free Solder Philips CE is producing lead-free sets (PBF) from 1.1.2005 onwards. Identification: The bottom line of a type plate gives a 14-digit serial number. Digits 5 and 6 refer to the production year, digits 7 and 8 refer to production week (in example below it is 1991 week 18).

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. Use only original spare-parts listed in the Service-Manuals. Not listed standard material (commodities) has to be purchased at external companies. Special information for lead-free BGA ICs: these ICs will be delivered in so-called "dry-packaging" to protect the IC against moisture. This packaging may only be opened shortly before it is used (soldered). Otherwise the body of the IC gets "wet" inside and during the heating time the structure of the IC will be destroyed due to high (steam-) pressure inside the body. If the packaging was opened before usage, the IC has to be heated up for some hours (around 90°C) for drying (think of ESD-protection!). Do not re-use BGAs at all! For sets produced before 1.1.2005, containing leaded soldering tin and components, all needed spare parts will be available till the end of the service period. For the repair of such sets nothing changes.
In case of doubt whether the board is lead-free or not (or with mixed technologies), you can use the following method: · Always use the highest temperature to solder, when using SAC305 (see also instructions below). · De-solder thoroughly (clean solder joints to avoid the mixing of two alloys). Caution: 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 "Workshop information". For additional questions please contact your local repair help desk.

2.3.5
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.
Figure 2-1 Serial number example Regardless of the special lead-free logo (which is not always indicated), one must treat all sets from this date onwards according to the rules as described below.

Figure 2-2 Lead-free logo 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 stabilise 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 stabilised 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.
