Text preview for : 14.2 sm english compact.pdf part of LG (Goldstar?) RI-28CZ10RX I\\\'m looking for a service manual, or information on how to get into the service menu. I would imagine that the 32\\\" version of this TV (RI-32CZ10RX) would be the same instructions, if anyone has a service manual for that instead...?

SAFETY INSTRUCTIONS
GENERAL GUIDELINES 1. It is advised to insert an isolation transformer in the AC supply before servicing a hot chassis. 2. Potentials as high as 33KV are present when this receiver is in operation. Operation of the receiver without the rear cover involves the danger of a shock hazard from the receiver power supply. Servicing should not be attempted by any one who is not competent with the precautions necessary when working on the high voltage equipment. Always discharge the anode of the tube. 3. When servicing observe the original lead dress in the high voltage circuits. If a short circuit is found, replace all the parts which have been overheated or damaged by the short circuit. 4. Always use the manufacturer's replacement safety components. The critical safety components marked with on the schematics diagrams should not be replaced by other substitutes. Other substitute may create the electrical shock, fire or other hazards. Take attention to replace the spacers with the originals. Furthermore where a short circuit has occurred, replace those components that indicate evidence of overheating. 5. After servicing, see that all the protective devices such as insulation barriers, insulation papers, shields and isolation R-C combinations are correctly installed. 6. When the receiver is not being used for a long time of period of time, unplug the power cord from the AC outlet. 7. After servicing make the following leakage current checks to prevent the customer from being exposed to shock hazard. LEAKAGE CURRENT COLD CHECK 1. Unplug the AC cord and connect a jumper between the two prongs of the plug. 2. Turn the receiver's power switch on. 3. Measure the resistance value with an ohmmeter, between the jumpered AC plug and each exposed metallic cabinet part on the receiver, such as screw heads, aerials, connectors, control shafts etc. When the exposed metallic part a return path to the chassis the reading should be between 4Mohm and the 20Mohm. When the exposed metal does not have a return path to the chassis, the reading must be infinite. LEAKAGE CURRENT HOT CHECK 1. Plug the AC cord directly in to the AC outlet. Do not use an isolation transformer for this check. 2. Connect a 2Kohm 10W resistor in series with an exposed metallic part on the receiver and an earth, such as a water pipe. 3. Use an AC voltmeter with high impedance to measure the potential across the resistor. 4. Check each exposed metallic part and check the voltage at the each point. 5. Reverse the AC plug at the outlet and repeat each of the above measurements. 6. The potential at the any point should not exceed 1.4 Vrms. In case a measurement is outside the limits specified, there is the possibility of a shock hazard, and the receiver should be repaired and rechecked before it is returned to the customer.

Figure 1 X-RAY RADIATION WARNING The primary source of X-ray radiation in this receiver is the picture tube. The chassis is specially constructed to limit X-ray radiation. For continued X-ray radiation protection, replace the tube with the same type of the original one. CAUTION AFTER REMOVAL OF THE ANODE CAP, DISCHARGE THE ANODE OF THE PICTURE TUBE AND THE ANODE CAP TO THE METAL CHASSIS, CRT SHIELD, OR THE CARBON PAINTED ON THE CRT WITH A HIGH VOLTAGE PROBE AND MULTIMETER (SELECT VDC) AND THEN SHORT CIRCUIT DIRECTLY TO DISCHARGE COMPLETELY.

1. ELECTRICAL ADJUSTMENTS
1.1. Supply Voltage Adjustment Connect a digital voltmeter to the cathode of diode D611 at the AV1 mode of the TV and set the screen voltage to the minimum with the screen potentiometer. Adjust the main supply voltage (B+) with P601 potentiometer to the following value (after adjustment, readjust Screen voltage). 21" Pure Flat : 132 VDC 25" : 145 VDC 28" : 145 VDC (147 VDC for A66EAK071X11) 28" Pure Flat 16/9 : 140 VDC 28" Super Flat 16/9 : 140 VDC 29" Pure Flat : 125 VDC 29" Super Flat : 125 VDC 32" Pure Flat 16/9 : 140 VDC 32" Super Flat 16/9 : 131 VDC 33" : 158 VDC
2. SERVICE ADJUSTMENTS
You need the special service remote control to enter and exit the service menu of the TV (you can order it from the manufacturer). All buttons of the Service RC are same with the user remote control, only service menu In / Out is added to it (please see the picture below). Navigation Service In/Out : Enters to / exits from the Service Menu P+ / P: Moves upward / downward inside the menu V+ / V: Changes the values or options
2.1. AGC Adjustment · · · Apply an RF signal with amplitude 70±1 dBuV to the antenna input of TV with a pattern generator (switch sound carrier to Off and switch "Video Ext" to On). Switch on the Service Menu with the Service RC and find the AGC with P+ / P- buttons. Measure the 38.9 MHz signal on pin 11 (IF) of Tuner with an oscilloscope. Adjust "AGC" to get following values: PAL BG, PAL SECAM BG, PAL SECAM BG-DK, PAL I versions : 840 ± 20 mVpp PAL SECAM BG-LL version : 600 ± 20 mVpp PAL BG MONO, PAL SECAM BG MONO : 750 ± 20 mVpp PAL I MONO : 900 ± 20 mVpp Substract 5 from "AGC" value and change "TEST" to this value. Exit from the service menu with the Service RC.
· ·
2.2. Screen Adjustment Adjustment is change according to SW versions. New SW versions start from SB8643_A05, SB8643_B04, SB8643_C04, SB8643_D04, SB8645_A05, SB8645_B04, SB8645_C03 and SB8645_D04. · If CRT brand is Philips and SW is old version, then Set Brightness value to "00" in the Picture menu and store. · Enter the Service Menu with the Service RC and select "SCRN" option with P+ / P- buttons and switch to ON with V+ / V- button. For new SW versions (or Philips CRT) "BRI 00" is shown on the screen. For old SW versions "BRI 32" is shown on the screen. · Adjust the screen potentiometer to the level where the screen is just black. · By pressing one of V+ / V- buttons, get the picture (SCRN is switched to Off). · Exit from the Service menu. · If CRT brand is Philips and SW is old version, Set Brightness value to "32" in the Picture menu and store. 2.3. Geometry Adjustments · · · · · · · · · · Apply a Cross Hatch Test pattern. Enter Service Menu with Service RC and select "VSLP" option with P+ / P- buttons (In this option, the upper half part of the pattern is shown and lower half part is blanked). Adjust VSLP such that middle line of the pattern is cut. For 16/9 sets, adjust VZOM to 25. On 4/3 sets, when VZOM is selected, set switches to 16/9 mode. In this case, adjust the circle of the pattern just touches to the upper and lower edges. Re adjust the VSLP if required. Adjust vertical position with VSHT, vertical linearity with SCOR and vertical height with VAMP. For 4/3 sets, adjust the horizontal amplitude with EWW. For 16/9 sets, adjust the 16/9 horizontal amplitude with EWW1 and 4/3 horizontal amplitude with EWW (EWW value is 21 lower than EWW1 value). For 16/9 sets, find the VZM1 option and adjust such that second lines from top and bottom just touches to the edges. Adjust horizontal centering with HSHT, parabola with EWPW and trapezium with EWT. For 4/3 sets, adjust the 16/9 general parabola with EWP1. Adjust the upper corner parabola with EWCU and lower corner parabola with EWCL, vertical parallelogram with HPAR, horizontal bow with HBOW.
For PIP versions : Select "PIP PRESS OK" and press "OK" button in the service menu. Adjust "HORPOS0" for horizontal shift of PIP window, "VERPOS0" for vertical shift of PIP window (press "POS" button to place PIP to the left-top corner), "HORPOS1" for 12-window PIP horizontal shift, "HORPOS2" for 11-window PIP horizontal shift, "HORPOS4" for right PIP horizontal shift. 2.4. White Balance Adjustment · · · · Enter the Service Menu with the Service RC and select "GRN" option with P+ / P- buttons and adjust it to "32" V+ / V- button. Adjust RED and BLUE for white balance. If white balance can not be adjusted properly change GRN value. Adjust BLOR and BLOG for red and green cut off. Exit from the Service menu.

Note: 1. All values in the diagrams are for 230 VAC mains supply. 2. Before replacing T601, check following components: R640, R604, R605, R609, C615. 3. Burst type standby mode was designed (Fixed frequency is 21.5 kHz for standby and 38.8 kHz for normal operation) . In standby the output voltages drop to about 1/10 of the normal operation values (except +12V which stays same), i.e. from +145V to 14.7V, from 15V to 1.1V, from 28V to 2.5V. In standby, Standby signal from IC101 is high. Then, T605 conducts, T604 blocks and thristor TH601 conducts. Therefore, +145 line which is now14.7V is connected to 12V. The regulation is done by ZD603 in standby and by ZD602 (TL431) in normal mode.
