Samsung lcd tv with model number LA32R91B Is repaired

The problem of this tv was saturation of white color in picture. first I contact to sam service as customer  to ask any help For repair of this TV they asked me about model number and answered me that  these model numbers are not repair able and due to panel problem the best way to get ride of is salvage.  by experience I knew that this could be the problem of gray scale ic in the TIME CONTROL BOARD .this is 48 pin ic that more or less the size is little bite bigger than a lentis  AS15-G



Mean while a repair friend of main offered me a used TCON BOARD   in good condition with same specification but very expensive that is why I preferred to buy a new board .also i have to mention that I can not find the  ic in our local market and in case I find the ic replacing such small smd is a big challenge so I decided to order it to china suppliers and buy a new time control 
After one month receiving the board from china and replacing the 
board problem solved







This is only example of timing control board or T-con
