Re: LG 50PA4500 - Sound with no picture
Hold off on swapping them over for now.
Unfortunately (as above) these TVs have a -serious- design flaw where the ribbon cable (orange thing) that connects to the plasma "glass" can become torn, due to a mis-placed plastic notch.
This would, unfortunately, mean the TV is scrap! (Sorry) And your symptoms, of a top chip shorted, are very similar. So I am a little concerned.
Do you think you can carefully lift off the plastic facia of the TV (the front plastic) and have a look at the ribbon cable? The damage should be very obvious. From what I remember, the plastic is held on only by a single screw at the top. You can leave speakers etc. attached, and the stand on the TV, as it will make working on it easier. Just need to lift it down a little to check that ribbon. Be careful as the front filter glass may come off - it's the anti-reflective screen for the display.
