Hi ,it has to do with the light engine.Either the DMD board and this it how it works:http://electronics.howstuffworks.com/dlp1.htm Basically if your tv is a dlp it has a chip that carries 2 million pixels when those chips are in the off position you'll get lines or discoloration.God bless you and your family.

If you have the following symptoms check the site www.TvRepairKits.com . They have a repair kit for this problem. 


Screen shrinks and expands - may or may not correct itself after the TV warms up. After a few days, weeks, or months of having the shrinking/expanding problem you may loose all audio/video but the power light will remain lit!

Hope this helps,
