Question about Projection Televisions
Try replacing the electrolytic capacitors in the power supply section. I started with replacing (2) 860uf 180v caps just after the bridge rectifier and continued along the circuit. Some (15) or so capacitors later,it finally cleared the the horizontal bars and lines and the high pitched noise. It also fixed another intermediate problem of no video, when turning on the power.
Here is a picture of what they look like:
