Check the caps in the High Voltage section. The voltage needed to ignite the gas to inside your screen to illuminate the whole screen is being depleted before it has a chance to light up your screen. The problem will be in the capacitors in your set.

Its probably a bad ribbon cable on that side of the tv. if u put pressure on that side ( on the plastic) it may resovle the issue. otherwise it could be a bad tcon board and the tcon board would need to be replaced.

Why my 42" sanyo DP42841 HDTV LCD SCREEN GOES BLACK ON THE LEFT SIDE?


That sounds like a faulty LCD panel tab. The only true fix is to replace the screen. This usually isn't cost effective.

Vizio 46 inch black screen on left side


Sounds like you either have a faulty LCD panel tab, failed LCD driver board, LCD/t-con panel bad connection, or a bad t-con. You will need to get a diagnoses to be sure.

I have a sanyo LCD 46 inch tv the model number is DP42848 and the left side of the screen is black when it is on. Even when left on for a while it does not clear up. we are still able to see what is behind...


It could be the video processor board (T-connector board) or its ribbon cables. This board has two ribbon cable that supply each of the two circuit boards for the LCD glass. One for the left and one for the right. If one of these cables has become disconnected, then only one half of the screen will work. To check the cables, you must remove the back of the TV. The video processor board is under a metal cover. Remove the 4 screws to expose the board. Check the one input and two output cables to be sure they are properly seated. If one side of the screen remains dark, the problem may be in the video processor board itself. You can probably get one on ebay. Otherwise the problem will be in the LCD glass circuits and it can not be fixed.

I have the same problem, my television is faded black on the left side with lines on the left top side. I have had the 46 inch unit for 1 year and 7 months. I am planning to write a demand letter to Sanyo and then taking them to small claims court woth evidence that this is a common problem with their units that they know about and is not trying to remedy. Also the Attorney general in Texas should have an interest in them (Walmart and Sanyo) selling these defective proucts in the state.
