Replace 6870QZE013C or 6871QYH053A (more likely).
The second is the Y-Sustain board, located to the left of your TV when looking from the back.
This is the one that usually burns and the fuse on it is likely shorted. Do not replace it, it will burn again.

My experience with 42" plasma tv's with no picture or sound was a missing power supply voltage. On the power supply board check voltages on the plug. The voltages should be marked on the board,

It might be one of the power supplies. There are three in this model. One for the sound, one for the video, and one for the computer components. The video power supply is probably shot. They cost about $200 a peice from LG. If there was a "pop" sound when the video stoped, then it might be one of the circuit boards in the back. Yet again, they are three, each costing around $200 from LG.
