I was given this TV with some issues in the hopes that i can fix it up and use it. it's a nice 42" plasma, around 3 years old.
it powers up and really works about 80% fine, but the image is not normal. i've attached 3 images.
i really only expect to use it for analog cable, and for HD OTA, so for testing, i'm using the OTA antenna and decoder.
1. when first powered up, static across the whole screen, but with the TV picture behind. there are 2 areas that dont' have the static. one is where the channel display was, and the other is where a warning of no signal was before it found the signal.
2. when i bring up the menu, most of the static disappears (except for a band about an inch wide near the top), and the menu is perfectly clear.
3. after the menu is cleared, the band of static stays, and i get green flashing vertical lines over the top of the whole screen.
i tried to find general troubleshooting webpages, and examples of images with issues, but i couldn't find any. are there websites out there that can help me figure this out?
in the mean time, i did pull the back off and compare some of the voltages with those in the service manual, and they were pretty far off, all high. i didn't adjust anything because i figure it's indicative of something bigger being wrong.
any advice?
