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.

There is probably a bad capacitor on the power board, I had the same thing happen to my 42LB1DR after 2 years. T.V. would turn on and white power light would blink, no pictue and no sound. If your'e a diy'er, it is not that hard of a fix. Take all the covers off of the back of the tv(UNPLUGGED!!!), then look at all the capacitors on the power board. lcd_repair_4_bad_capacitors_lg.jpg
These are the capacitors, look to see if any of them appear to have a bump on the top of them. They are supposed to be flat, you can also tell if one of them has gone bad if there is an oily substance on the metal cover that was removed. If one of them is in question, carefully remove the board, and take it to an electronics store to have them sotter ?sp on a new capacitor. It ended up costing me around $40.00 to have this done. Good luck and if you are not comfortable trying this, than take it to a repair shop, but I was quoted around $450 to take the T.V. in. No Thanks

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)?

Use that to see if you can sort it... Otherwise get a "Quote" for a professional approved service center.

My 42PB4D turns itself off and immediately back on. Interestingly this happens a lot but never when watching a dvd nor in the wee small hours of the night.


There can be several causes for this, few of which you can do anything about. However, a few things to try:

1) Replace the batteries on your remote control.
2) Try resetting the logic functions on your tv by unplugging it for a minute, then plugging it back in.
3) Try covering up the infra-red receptor on the front of your TV to see if you're getting unwanted signals from the receptor. taping a piece of foil over that area is perfect. If it doesn't stop after doing these two things you'll probably need to take it to a shop.
4) If this does stop it, then look for unexpected signal sources. Have you added a remote control extender? Added a new device to your audio-video system? Changed to a new remote?

I hope this helps. Joe
