Question about JVC HD-70G886 70" Rear Projection HDTV
Get some freeze spray from radio shack then try placing a little spray on each chip on the video board and power supply board and each time you spray a chip look for the picture to clear up. When the lines go away you have located the bad IC.

I have the exact same issue. TV guy told me today that it's the light engine but I'm doubting that prognosis now.
I have a JVC HD-70G886. Today when I was watching it vertical lines appeared in about 5 areas across the screen. I checked input sources and it was the same for all. I had replaced the lamp about 2 months ago and it has worked great until this. I unplugged it and let it cool for a couple hours. When I turned in back on the same lines showed up about 15 seconds after I turned it and seemed to get worse. Is it a power supply problem? Any suggestions? My email is [email protected].
