SERVICING TROUBLESHOOTING NO POWER No Power Check all supply voltages from SMPS. Are all sources present? Is power control line on P808 (RLY) at 5.0V power on. Yes Yes No Are any sources present? Replace SMPS. Loc (18), Pt # 809-10723 No Yes No No Unload missing/low source. Turn unit on. Does the source return to normal? For additional technical support Contact 877-9-ZENITH Yes If problem is other than main Video Scan Converter PCB. Contact Technical Support at 877-9-ZENITH.
SERVICING NO RASTER No Raster Is all of the raster missing? No Is part of the raster missing? Yes No Is 15V present on P803 and P804 on SMPS? Yes No Unload P803 and P804, does 15V return? Yes No Replace SMPS Loc # (18) Pn # 809-10723 Yes Check ribbon cables for proper seating or damage.
SERVICING 2. Press the VOL + or VOL - button. ADJUSTMENT INSTRUCTIONS 3. It displayed all of the black on the screen and then adjustment is started. PRECAUTIONS Because this is not a hot chassis, it is not necessary to use an isolation transformer. However, the use of isolation transformer will help protect test instruments. Adjustments must be done in the correct order. They must be performed in the at a temperature of 25±5°C and 65±10% of relative humidity.
SERVICING AGC ADJUSTMENT 1. Connect the signal of PAL-B/G 05ch. to Antenna jack. 2. Connect Multi meter to point(J150) of AGC adjustment. 3. Adjustment the voltage of Multi meter to 2.3 0.1V by changing VR102. 3. Supply window Signal to TD-710 in pattern generator. [ When adjustment is operated manually, operate process (3) to (7) regular sequence, when adjustment is operated automatically perate process (1) to (2). 4. Select STB CXA2101 by pressing SVC,ADJUST button on Remote Control for adjustment. 5.
SERVICING SERVICE MENU ADJUSTMENTS 2. The chart shows starting value settings for adjustments. 3. Use the UP or DOWN keys to scroll through the menu and the LEFT or RIGHT keys to make the adjustments. 4. To exit this portion of the service menu cycle power off and on. If the Main Video Scan Converter module (Part# 80910722) is installed the unit will come on when A/C is applied. The EEPROM data will be in Factory default values.
