SOURCE: 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.

Open the back cover and check the fuses on Y Sus Board and X Sus Board. If you can find a blown fuse, just replace that board and your problem will be fixed.

I had the same exact problem as posted above. My 50" LG plasma was out of warranty for 1 year! I called the LG executive call center, and they were very helpful. They offered to pay for the parts and labor. They recommended a few local repair shops, and they set everything up for me. The tech came out within 4 days with one part. The tech had to come out one more time the following week, since more parts were needed for the repair. The Y sustain board, along with 2 adjacent parts that are required to be replaced as a set, and the power supply had to be replaced (parts alone cost just over $900). TV is like new again; I'm very happy with how LG handled it, and made what could have been a bad experience a good one.

I have an LG TV 50PV450 Plasma TV, and after a storm last night, it won't power on, however,standby light remains lit, solid.


Look for blown capacitors on the power supply board. They will have domed tops instead of flat tops Some will look puffy too. You can get a repair kit if you're handy with a soldering iron or replace the entire board from here: TV Parts Universal TV Stands DLP Chips ShopJimmy

White Screen, Video is readable but faint


Any time there is a distortion in the picture/graphics on the screen, this is an indication of a defective LCD display. LCD displays can fail even if the screen isn't cracked. It sounds like the graphics are washed out. More info on defective LCD displays can be found here:
