Panasonic 42" Plasma TV

My TV constantly makes popping sounds when the TV is on. The picture and sound are fine.....Any idea what's going on?

    Panasonic TH-50PX77U - same problem. It starts after about 20min of the TV being on. Some pops are louder than others. I'm thinking its a relay of some sort in the power supply. But who knows. I haven't called Panasonic yet... The TV is 5 months old.

If the sound isn't coming the speakers then its cabinet expansion. Specifically between the panel and the front cabinet.
I believe Panasonic has a fix for this.

We bought an LG 42'' plasma T.V. 42pcida-ec from dixons 2006 £1500. the other night heard a popping sound and the picture went off but the sound stayed on. LG wanted nothing to do with it and were no...

That pop was a "cap" capacitor blowing, open up the TV and look for a burn mark. And of course LG isn't going to fix or supply info for free to fix this for free, that is just good business, I would agree with them..

42 inch LG Plasma TV - Lost picture

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.

42 inch LG Plasma TV - Lost picture

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.
