This afternoon our LG Plasman tv was working fine. There was a popping noice and then the picture was gone. I have turned everything off and back off. Unplugged and plugged connections back but still not picture.
You popped the plasma HV generator. Do you use a UPC all the time, if not then power line surges or brownouts can cause this type of problem. Needs Pro shop repair, expect around 450.00. PS: buy a upc for around 10 minutes run time $80.00 ??

The Video (Picture) is SEPERATE from the Audio component of the TV. One can work when the other has gone south. From what I see, the Audio controller board may have been damaged somehow and needs to be replaced. Contact a serviceman for details.
I've also had a popping noise on our 50" LG plasma TV, however the picture has not gone, but has turned grainy and colors are weird. Can this also be a blown fuse or a more severe problem (ysus board or similar)?
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.
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 had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions
