Check Your Rear Projection Light Open Back Cover it a little Door on the back ov your TV Set Possibilty Light Burn Out ....Cause of this Problem Fan Malfunctioning Or The Bulb as to be change for new one ...

have you attempted a different video source into the TV (Gaming system, another DVD player, Reciever)?
The issue may be that the cables you are using may be old, and are severely damaged. inside of those cables is a standard RG-59 Coaxial Line that is extremely flimsie.
try and use separate cables or a separate input.
If the input change works, is most likely the switchboard on your TV (Hardware) and will need to be serviced. Another option to use is a Video switch ($35USD), and not pay $300+ for system repairs.
Have you tried selecting a different input( do you have the remote?), if so have you set your input to accept HD input ( you access this thru your 'Menu" button on your remote). I run my HD input from my game console (X-Box 360) and have to select HDTV input channel (there are 2 of them along with 2 cable inputs), and have not had a problem with this at all. good luck.
I have the same tv but my dvd surround is a toshiba, that shouldn't matter though. When I watch a dvd I go to component 2 which is where I have my dvd connected on the input of the tv when I watch tv and want the surround on I go to component 1 which is the tv input then on my dvd player I go to auxillary and I can watch tv in surround. I don't know the LG home theatre system but you should be able to select your inputs like between dvd, tuner, aux. Flip between them and you should get sound. hope this helps.
