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.
