    The cable seemed to "go out" while watching tv then started working again for about 2 weeks then went out again. The weather was colder so thought this had something to do with it since it was warm when it started working.

    When I switched my LG TV on the screen is blank although the light on the bottom panel shows that the TV is on. It seems I've to leave the TV on (with the blank screen) for several minutes then switch it off and wait for a minute or so and switch it on again for the screen to light up and picture to show. It's like the screen needs 'warming up' time. Can you assist? Many thanks!

I have a LG plasma 42PC1DG, watching tv loud pop then no picture but still have sound, left tv unplugged for a while still no picture?


probably the pop was a fuse blowing inside that only controls the lamp should be an easy fix but open the tv at your own risk

My LG Plasma television DU-42PX12XC had a loud pop


Your tv contains protection circuitry that would shut down the tv if the ymain was out. If the ymain had blown, you'd have no sound and just a flashing standby light. My gut tells me you need to replace the Power Supply Board (PSB). I've seen this before and after spending too much money trying to diagnose a ymain failure, I was surprised to learn that when you have sound but no picture, the psb is a gonner. Try ebay, shopjimmy.com or discount-merchant.com for a replacement.
Good Luck!

Unfortunately, that board is the inverter board. And for this model the inverter board is only supplied with the the PDP panel. The panel is quite expensive, here's a link if needed:

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.
