T.v works fine for a while then goes to thin rainbow across middle of screen. If you turn it off for a while it will come on and work fine again for a while. It has a thin bar of color all the way across the middle of the screen. Please help what could be wrong?
The signals on each projector are the same and swappable. you can use a signal cable or plug off of another gun like green to trouble shoot with to see if the red signal is the problem. also press on any chips or plugs to make sure they are seated good on the board inside TV. Also on the pc board inside diods and regulators break down with heat when they are going bad.

I have worked on projection displays for about 17 years 20years electronic. and this sounds like a vertical deflection amplifier problem. this is if the lines or the rainbow you said that you see are horizantal.

now the tv is working fine but there is a faint
red line across the middle of the screen going
horizantally. Is this in the screen or in the signal?
thank you for trying to help me.Im pretty sure
something in a board is starting to short out or burn up. the problem is I cant parts for this t.v.
If the problem was identified could it be resoldered. Should I just buy a new tv
this one is a little over a year old
