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.

SOURCE: LG 42'' TV has no sound but great picture. How do I get the sound?

You shouldn't need anything plugged into the accessory jacks to get local sound from your set. Go through the main setup menu and check audio settings; they may be set to turn off the internal speakers to send the sound to a home theatre that you apparently don't have. Most sets have that as a selection and supply L-R audio for an external system and mute the internal speakers.
FYI: The three connectors you mention are coded as follows:
Red - right channel audio White - left channel audio Yellow - composite video (contains synchronization signals and video)
These may be input connectors (for external VCR/DVD decks) so check your owner's guide to verify.

This is almost certainly the device that sends electricity to the the plasma in the panel after failing. Bring to your local repair shop and expect to pay 300-400 parts and 100-200 labour.

Cheers,
Stephen

47LG70 - PICTURE WENT OUT. STILL HAVE SOUND. HEARD A POPPING NOISE WHEN PICTURE WENT. TV IS ONLY 1 1/2 YEARS OLD. ANY IDEAS WHAT MAY OF HAPPENED.

I have had the same problem off and on with my 47LG70 for months. When the "popping" noise happens, the blue light in the corner stays on, so I know the tv is still on (sometimes I still have sound, sometimes I don't). Sometimes the screen goes black, but other times it is blue. If I turn the tv off then on again, it might stay on for seconds, minutes or hours. It's been very frustrating.

This seemed to happen right after I got my new Comcast box, which came with an HDMI 1.3 cable. I read somewhere online that this tv might not be compatible with that cable, so I unplugged it and am using component cables again. I just did this today, so I don't know if it will work, but so far the tv has been on for 30 minutes with no problems.

I'm pretty ignorant about HDMI compared to component cables. I imagine I will not get as good a picture with the component cables, but I am willing to sacrifice quality if I can just get the darn thing to work. Mine is also only 18 months old.

Hope this helps. If it doesn't, maybe someone else out there can help us both.

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.

LG TV completely dead

Hi,

I'll think your power supply is down.
Since your tv is 15 month old, you've still got waranty left.
Just contact you supplier or LG service.

Kind regards,
Gerard

There could be two possible failures:
1. The backlights are defective (not a common failure for a 14 months old LCD) or the backlights driver/inverter is defective.
2. Power supply failure(very common failure on LCDs) will cause the symptoms you described.
