Could be y board, tuning control board, solder problem, internal cabling problem, lose connection, bad power supply etc...
You will have to open the back cover and see all connection or ok, tapping here and there to see if the problem goes' away for bad connection or solder problem.
Try insulating were the problem is, I would think it would more on the y board seen this. Most board or not repairable I have tried and tried and tried and find that I was just wasting my time , most board or about $400.00 .

Good luck

How do I connect my old Sony 5.1 surround system to my new LG Plasma set?


You should be able to run most of your systems trough it. I do belive that it has IR connections that either your TV or possibly the cable box has to export the audio to the Sony. Hope this helps

Hello
The T Con board of your LG that generates high voltage to plasma screen is fauty. It is somewhat costly board, and can be repalce as card basis. As the set is new, and warranty will be there with it, just contact the authorised service center and get it repalced by them. They have the liability to do that. If you want to repair it by yourself, tou have to spend an amount from your pocket. OK.

I have a LG plasma, do i need a optical digital audio out cord to use surround sound?


In order to get true 5.1 surround sound you need to use either digital optical (fiber optic) cord or digital coax cord(RCA style ends) to link between your TV and your digital source such as DVD,digital cable box,digital satelitte receiver.You can route the audio through the TV but that's not the best way to go,I recommend going directly from the digital source to your surround sound receiver for optimum sound. Good luck !

I have a LG Plasma Flat screen TV. I purchased it


With seeing the picture it will be hard fro me to tell what..I am going to guess according to the information you've provided.
It could a buffer or a signal board(s). This TV is only 4 Months old I would call LG and file a warranty claim. LG (800) 243-0000

Best of luck

Unfortunately damage of this nature is not covered by the manufacturer warranty, however you may be lucky as it does not sound like the plasma panel fractured. Find your nearest LG auth service center and maybe they will find some plug or connector may have have been jarred loose. Good Luck
