Does it go away when the set warms up? or if you tap the set? Sounds like a possible defective LCD panel tab. Samsungs and Sony's are known for this.

I had the same problem with my Samsung 40" LED tv. I was able to fix it for no money, all on my own. It took a little bit to get the picture back but it was a very easy fix. Watch this video on YouTube. I hope this helps.

SOURCE: LN37A550 LCD TV has washed out image

It is possible the problem is caused by a wrong option byte setting in the service menu. The correct setting depends on the type LCD panel used in that version. Version number can be found on a sticker on the right side of the television. A bad main board or TCON board can also cause that type of problem.

SOURCE: LNS4692D - TCON Board (seems there is a systemic issue)

You have to be very careful with the flat ribbon cables and be sure not to have an electro static discharge to the board while handling it but it is not that difficult of a repair. It is the board that is located at the top center of the back of the lcd panel. Depending on your problem, eg. line in picture, no picture with backlight.... it unfortunately only fixes about half of the units. The other half need lcd panels which are very expensive. hope this helps.

SOURCE: Hello, I have a Samsung LN-S4692D.

You cannot test the T-Con bd with a meter. However if you have the luxury of having another same model tv, you can install the bought T-Con bd and see if it is good or bad. Since you said the Menu and channel flashses, then I would replace the Main board.

I have a Samsung model LN40D630 with double picture ,I changed the t - CON BOARD AND ribbon still have a double picture what next?

Always the double image will not by the faulty T con board. There can be problem with the buffer ics which are located in between the tcon and the lcd panel . The buffer ics are not replaceable one because it integrated to the ribbon which is moulded to the panel. Either you have to go for a new panel or a new tv.

This may be due to a faulty Timing Control board (TCON board). I had a similar problem with my Samsung LCD TV picture being split vertically down the middle. The image on both halves appeared fuzzy and in reverse (mirror) including the menus. I replaced the TCON board and the problem was resolved.
