I know there are a lot of faults listed re this model Sammy but I havent seen this one before. The set works with a good picture, then about half an hour later the contrast will begin to advance by itself to 100%. You can reduce this in the menu, but again after a short while, it will increase once again.
Now, my instincts tell me faulty EEPROM, but before I embark on a wild goose chase, has anyone had this or a similar fault before.
Many thanks
Bill

Remove the t-con cover. Is there an AS15G [or F] on the t-con, small square 48 pin ic? If so, hit it with freeze when the picture gets bright. Picture back to normal - replace the ic.

Thanks Downunder, I'll have a look at that, but I rather doubt that a fault on the tcon board would alter the software values in the menu, which is what makes me think EEPROM
Cheers

Kilroys:
I agree with Downunder, but I changed the T-con card BN81-01909A

Hi, thanks to those for the replies. This is a fault I haven't encountered on this model before, and I don't want to swap the tcon needlessly. I'm going to try a new eeprom first and will let you all know the outcome. Kilroy, did you have the same symptom? or are you going from gut feeling ? Personally I can't see how a fault on the tcon could alter the values in the menu.
