G BOARD
3-3. +B MAX VOLTAGE CONFIRMATION
The following adjustments should always be performed when replacing
IC6503 R6590.
1. Supply 130VAC to variable autotransformer.
2. Receive dot signal pattern and set the PICTURE and BRIGHTNESS
settings to their minimum.
3. Confi rm the voltage of TP +B 135V is less than 137.0Vdc.
4. If step 3 is not satisfi ed, replace IC6503 and repeat steps 1-3.
3-4. +B OVP CONFIRMATION
1. Turn on set.
2. Set input conditions.
3. Turn off set.
4. Separate R6809 (D Board) from +135.
5. Apply external 160 ± 1V DC to open end of R6809.
6. Turn on set.
7. Measure voltage at Pin 8 of CN5006 (D Board). Voltage should be
less than 0.8V.
