Led tv half screen goes dark after warm up. Sound and picture good on left half. Started with dark spot upper left, then left side completely dark.

SOURCE: TV has a greenish tint

first off are there any speakers close to the tv ?. if so move them secondly your degauss circuit may need servicing.

Hi Guys

The Blue dots or discolouration you are seeing is due too the Blue LCD screen having cracked from excessive heat. This normally happens when you have a power failure while the Television was on. This obviously because the Blue LCD sits next to the lamp - the main cause of heat. The correct part number on the 60" is A-1086-952-A. It is very, very ,expensive.

Sorry to have been the bearer of bad news. Good luck : )

I had the same problem. Panasonic is kind of a pain about the whole thing. You have to find out who your local Panasonic repair place is, tell them there is a service bulletin and they will get on it. You must be diligent! Do not take no for an answer! If it comes down to it, and the repair shop won't do it for you, then call Panasonic and endure a loooooong wait time. Trust me though...this is the issue. Once the eeprom gets fixed/updated/whatever, the picture looks amazing! Good luck.

SOURCE: screen goes dark, sound goes quiet...

I have a sony KDF-E60A20 projection tv. The picture would go out for about 30 seconds and come back on. It would continue to cycle this way. The green power light would stay on and not flash. The sound would go off when the picture went out and come back on when the picture came back on. I tried taking the bottom cover off the back exposing the fan and blowed it out with a vacuum cleaner, also taking out the bulb and blowing it out. That didn't help. So I ordered a new bulb from Advancedlamps.com and that's what it was. I have now had it on and off for two days and no problems. Cost of lamp was $107.00 including shipping. Good Luck!

SOURCE: Vertical colored lines on left half of screen.

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.
