8. Slowly increase AC voltage at the input of the isolation

transformer and confirm HHS voltage measure 31kV for 20”
models and 33kV for 25” models.

9. Turn power off and remove jigs.

3. EEPROM replacement

If a new EEPROM integrated circuit is replaced for servicing, follow the next procedure once that
the memory is properly assembled:

1. Turn the TV set ON.

2. Enter to service mode.

3. Once inside service mode the first image that appears on-screen

is the ID1 register with the respective address value (FF) like the
image below.

Note:

All 3 registers (ID1,ID2,ID3) should appear with FF values if a new
EEPROM is assembled.

4. With “VOL” keys adjust the correct value according with the

service adjustment table (see “Service Mode” section in page 15).

5. Change to the next ID switch register with “CH” keys and repeat

the same procedure as step 4.

6. When replacing a new EEPROM be sure to set the correct ID

switch values for each model.
