I had the same issue on a LG 50PX5D, bought in 2006. I changed channels and the picture froze, audio was OK. Then after shutting off, when turning back on got exactly same symptoms. Repair guy says X and Y boards to be replaced. I expect to have it back in a week. PS happened after a power hit, it worked ok for a few hours then this.

Your unit is in protect mode a short circuit has occured either at x,y z board.Check fuses F52 on y Board,FS1,FS2 on Zboard.Remove P1,P2,P3,P4 if power supply voltage is normal replace right x-board.Remove P6,P7 if the power supply voltage is normal replace left x-board
