I have a 3 yo Zenith 50 inch plasma HDTV manufactured by LG. Tonight it made squealing and popping noises and we shut it down. Now, when we turn it on, you can sort of see a picture through shifting pixels. The sort of static covers part of the screen and moves around. Any ideas?
kenpogue, Yes, I'll just bet it's a "switch-mode-power-supply" that has failed because of some bad or poor quality electrolytic filter capacitors or poor quality of wave soldering of components on said printed circuit boards. Ask the service tech when you call him up, how many $100 bills you should have in your hand when he shows up!!! Prior to making the CALL, do yourself a favor and view some LCD repair vids at YOUTUBE first. The longer ones will be more imformative. You might even find one very similar to your own being repaired. Some of them are pretty good and you will learn a lot. You may even want to tear off the rear plastic panel to see what is inside your set as long as it is out of warranty?? Please pay particular attention to where these do-it-yourself-guys perform the task at hand. They and spouse may need to sleep on floor for a day or two!!! lol.... good luck guy. They (ZEC) laid me off over 10 yrs ago when Lucky Goldstar took over. Bye for now. 12fixlouie If this response was helpful, please rate on fixya.

My plasma Panasonic's color is off. ERverything that should be blue looks green. Green looks almost grey. What is going on here? Have tried to adjust the color with on screen adjustments and nothing gets even close. What is going on?

for some odd reason, it only does it on the regular non-HD channels?? It never cuts out when watching something in HD. Also, using the DVR, if I rewind back over where the sound cut out, the sound comes through. Makes me think it is the TV versus the source (cable box). Any ideas? Thanks!!
