It can be a couple things. Something bad on the power board. Or the vertical output circuit. How long ago did you purchase the television. Your best course of action is to have it serviced. If you need any information or other assistance let me know. Thanks, Lee
You have a chip that is overheating due to heatsink coumpound being dried up. You need to find that chip and heatsink and apply new compound to both parts.
The light engine on your set is burned out.
This is a very complex replacement.
I hope your tv is under warranty repair cause it is expensive.
It happens because the heat from he lamp over time burns out the lcd's that create th ed and blue leaving the gren which is always furthest from the lightbulb (YOUR tv has four lcd's in a row..red, blue, gren and then black.
If you wish to try and replace it yourself there are places online where you can buy a replacement engine.
Sounds like the green tube shorting intermittantly. Have a qualified tech use a tube restorer to check for shorts, or the loss of the 300v line to the green tube.
screen goes green
