Why do you think there is an eeprom?
Many micro computers have them inside now days.
Hopefully he might get back to us, and give us details as I asked above - but certainly only a few years ago use of 8 pin EEPROM's was still commonplace in TV's. Corruption of them was also
EXTREMELY common, and manufacturers seemed to struggle with preventing it. I used to keep a folder of different EEPROM files for different makes and models, for that exact reason.
The classic example was probably Samsung, who for years knowingly fitted sub-standard electrolytics (which often failed while still under the initial 12 months warranty) - the resulting ripple and wrong voltages on the supply rails commonly corrupted, or damaged the EEPROM.
On the Samsung sets there were basically four options:
1) Replace the EEPROM with a new ready programmed one from Samsung.
2) Replace the EEPROM with a new blank one, which you programmed using the file from the folder I mentioned above.
3) Replace the EEPROM with a new blank one, which the TV detects, and then fills with original factory defaults that are stored inside the micro-controller.
4) Short SDA and SCK together on the EEPROM (with a small screwdriver) and power the set ON, this makes the set think the EEPROM is blank, and by removing the short at the correct time the existing EEPROM will be programmed with the factory defaults.
The problem with option 4 is if the EEPROM is faulty or damaged, but it was the preferred option, as it was faster and low cost - and if it didn't cure it, then replace the EEPROM.
