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.

The red stand by light is on but the screen is


This is a common problem with LG 42 and many were recalled to change the offending board and part of this p-oor quality TV

March 9th, 2009

Pros: The picture is good, great size for our well lit 7m x 7m room.

Cons: Sound delay - we assume that is to do with being digital, the sound lags behind other analog TV's in the house.

Overall: LG service is pretty ordinary (not just for TV). There was a product recall on this TV, but the service department was unaware it covered this model - I had to print out the details from the LG website when the serviceman came. We've now had the TV for over 2 years and a red tinge became apparent at top and bottom of screen, we placed a warranty call and the local service agent came and took the TV away two weeks ago. They are still awaiting parts from LG to repair the problem.
Please rate my help++++Thanks for using FIXYA

I have an LG flat screen no picture or sound


As your TV is three years old, I would suggest you contact your LG dealer to arrange an engineer to call to do a software upgrade on the it. The current software will be out of date & if you are connected via the HDMI connector then this can give audio/video problems.

Have LG 42 inch plasma, 1 inch black line down center of screen, picture good other than black line blocking center of screen, comes and goes sometimes


Sounds like the middle scalar board is defective. Since the issue comes and goes it could just be a loose connection to the between the scalar board and the PDP Module (plasma panel).

Great caution needs to be taken when checking this connection because it is a ribbon cable connection it and needs to be put in correctly aligned or it could cause a short in one of the circuit boards.
