The TCON board is something you read about on the web and frankly WAY OVER DONE as a fix. The problem is not only do folk wish for it to be this board there is now a shortage of boards as folk buy them up in hope.
The cost of the counter is 150 bucks here so the fix is to replace the display if out of warranty.
I have a Samsung LA32A550P1RLXL LCD TV and few days before suddenly the display came with small squares in whole screen though the picture from all sources are visible but with above mentioned squares and sound is OK. Pls check the below image links for better understanding. Please help me to identify and to rectify the problem. Is it TCON Board problem or any other?
