Samsung led tv after turning on the screen will become fuzzy/vertical color lines then will click to turn off to on again....Samsung model# LN52A650A1FXZA

SOURCE: vertical colored lines no picture.

if the tv is less than a year old , call 1-800-SAMSUNG for warranty repair, the lcd panel is bad

SOURCE: When I turned the tv on only vertical lines appeared

I talked to a Samsung support helpline and it needs to be taken to a service center for repair.

The machine is overheating and the graphics chip on the main board is acting up cause of it. Make sure there is no dust or dirt blocking the air vents that would cause the system to heat up more then normal.

If that doesn't do it then maybe think about getting a cooler for the system, here is a website that talks about a few of them. Click here.

If that doesn't help then your mainboard is going bad and would need to be replaced.

Go to the last page of troubleshooting in the manual and perform the system reset procedure. Basically hold the Wega "arrow up" as you manually switch the TV off. It will automatically switch back on and reset. I had only vertical colored lines on the screen, with audio but no response to any remote control functions. The rest worked perfectly.

I had this problem on a 37" Viewsonic LCD. Pulled it apart and through a process of elimination, I traced the problem back to a small board with several flat white ribbon cables coming out of it. The board was near the top center of the screen and under a ton of other equipment requiring almost a total disassembly.

This small board was clean but I noticed one of the rubber standoffs had slipped down and was making contact with one of the outputs running to the LCD. It also happened to be the output running to the section of the screen with the problem.

I postulated that the sticky glue on the rubber standoff may have just enough conductivity to cause a problem. Moved it so that it was no longer touching anything electrical and then reassembled the TV.

Afterwards, I turned it on and was pleased to see the problem has gone away! If you're having the vertical line problem, then maybe this could be your problem too, especially if you have a Viewsonic since it could be a manufacturing defect.
