How do I fix a washed out picture problem on my 46 inch samsung series 7100 led tv?

The common cause of this issue is down to a board that connects the screen to the main circuit video board of the tv. It is usually located top middle of the tv and has 2 white ribbon type wires coming from the top and is normally covered in a metal shield.
There will be a part number on the circuit board, this will be the one to find online which matches your screen. If you got an identical tv with another fault, it may not have the same part as each combination is different depending on the manufacturing line or part revisions.

The part you are looking for is called the T-Con board . Hope this helps.

Yor tv have problem with T con board. T con board is one which drives the pixels of the LCD panel. If any of the driver satge in the T con board is faulty then this problem can occur.

Some times bad contacts on the connections of the t con board can cause same problem. Remove the tv and find out the t con bard. Remove the connections to it and the reconnect the connections. Then check, if the problem remains the same then the tv need a new T con board.

You have didn't mentaioned any model number of your tv. So it is not possible to show you exactly how T con board looks.

Normally in all lcd tvs the tcon board is place on the bottom or top middile position. Which will be cover with metal cover or aluminium foil.

You didnt specify the brand and model number of your TV any way the above mentioned problem can occur when the T-con board of the lcd Tv have some problem. There is no repare possible with these boards. The t-con board controls the pixels of the lcd panel. When any one of the out put from the t-con is faulty then the specific pixel or row of pixel will be absent. That's we see as lines or missing pixels. You can find the T con board normally in the bottom centre or top centre of the LCD tv covered with metal cover or aluminium foil. There will be a part number in the board. You have to replace a board with the same part number.

Some time there will be some loose contact in the connections of these board can cause these problems. Before going for a new board remove all the connection to the board and then reconnect it. If then also the problem is there then you need to replace the t con board. This is a common problem to the lcd TVs. Normally t con board will look like one in the picture. If you need any more assistance fell free to contact me through fixya. Next time when you post a question remember to add the make and model number of the product.

This might be a bad T-Con Board. This is the board that is in the middle top side of your TV. It connects to your main board (with the hdmi inputs) to the LCD Screen. Your TV has a major issue with the T-Con Board going back. The T-Con for that TV is avaialble here 55 46T03 C11 Samsung Con Board for LN46B650T1FXZA
