So other problem was the power supply. This problem is the TCON board.

what do you mean by distorted?


are colors wrong? or are colors washed out?

Power supply board u fixed before was good,but the tv main Tuner signal board it was working on it last leg.Distorted picture screen loud static noises are the indications of the tv main Tuner signal board are not regulating signals of all of those ICS output on the tv main Tuner signal board it is dying and now it is dead.Don't change the T-CON bord it is good.Tries Shopjimmy.com,Ebay.com to buy a whole refurbish tv main Tuner signal board for the replacement.

Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish board that call T-CON board to do a replacement.This T-CON board sit in the middle at the bottom of the tv LCD screen panel.This T-CON board control all the picture pixels going throught to the tv LCD screen panel.

had a very similar situation with my Phillips 42 in. LCD TV.

Here was my Problem. The Power Supply Board. I opened it up( Warranty was Expired) and found several faulty capacitors on the PSB. Its pretty common. Major Electronic companies were sold faulty capacitors that fail in 2-5 years instead of 10-20 due to a lack of preservatives. It wouldn't surprise me if you have the same problem. TV will work fine for a few years and then just fail completely or slowly deteriorate.

Here are the solutions
1. Have it Repaired
2. Check for faulty caps and if you find some(budged or leaking) you know you have located a problem
Remove the board and replace the whole thing.
3. If you have some soldering skills you can replace the faulty caps.
Caps are very inexpensive, under a dollar in most cases. I replaced 4 for about $5.00

Hope this Helps.
Good Luck

Hi Bob. The first Board to cause this problen is the Main bd. The next bd to cause this is the T-Con bd which is mounted on the Panel. Since you saw horizontal lines and that you have text on the screen and are missing audio from the tv means that the Main bd has gone bad. Have a trained Samsung tech service your tv. Call 1-8020-Samsung as they can direct you to a Qualified tech in your area.
