I have a sanyo 50 inch plasma tv that when you turn it on in the mornings it would click on and off repeatedly until warm up then it would be fine until it cools off when you shut it off the whole clicking thing would start again. well after 2 years of dealing with that it finally just lost picture yesterday but it still will do the clicking thing and once warmed up i still get sound just no picture at all. any ideas?

Our LG 50" plasma tv screen went black after a popping noise but still had sound, after great diliberations decided to take the back off and have a peek!
We unplugged the tv and tested the fuses (there were three we could see) one had blown, the one on the left as you look at the back of the tv it also has one above it. We wrote the code/seriel number down and took the fuse to the electrical wholesalers Maplin and bought a pack of 10 fuses for £1.29 replaced the fuse in the tv and everything now fine!!!!!!
Hope this might be of use to anyone whose lost the picture after a loud popping/snacking noise but still has sound.

I am a military spouse and our same tv did the same thing on Super Bowl Sunday 2009! We did everything we know to do: call the company, called the repair man, etc. There apparently isn't a solution to this that wouldn't cost more than the tv is worth. So I got an attorney to start a class action:

Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.
