ADJUSTMENTS AFTER REPLACING THE MEMORY IC [IC802]
When IC802 (EEPROM) is replaced, IC801 (CPU)
will automatically write the initial reference data into IC802 for basic TV
operation. However, the bus data should
be checked and some bus data should be set up before attempting the service
adjustments.
INITIAL BUS DATA SET-UP
Note: When IC802 (EEPROM) is replaced, the Service Menu No.
4 VS (V Size), No. 10 VSC (V S Cor.) , No. 28 PRE (Pre Shoot Adj), No. 32 BSG
(Blk Str Gain), No. 42 RAD (RF AGC Delay), No. 48 SCO (Sub Color), No. 49 STI
(Sub Tint), No. 50 SSH (Sub Sharpness), No. 51 OPT (Option 1), and No. 52 OPT2
(Option 2) should be set up for proper TV operation before attempting the
service adjustments.
(Bus data is in hexadecimal format)

- Press the MENU key to turn off the Service Menu display.
This unit is equipped with a Power Failure Detector function
included in the CPU which checks for an abnormal condition in the chassis power
supplies, including the power supply derived from the Horizontal Output
Transformer. If, while the power is on,
a failure is caused by any of the following that results in a low voltage
supply, the CPU will turn the unit off in 1.5 seconds to prevent unnecessary
damage:
- Failure within the power supply circuits.
- A short circuit in the load side from the supply.
- Stoppage of the Horizontal Output Oscillator caused by the X-Radiation protection Hold-Down Circuit.
Check the following if the unit is turned off by the power
failure detector.
- Disconnect the AC power cord (120V AC line) for at least 10 seconds.
- Connect a DC Voltmeter to the following TEST POINTS.
- Press the Power key and check for the proper voltage supplies.
- If any of these voltages is low, the power failure detector should turn the unit off within 3 seconds.
- Check all circuits listed above.
