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.

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.
