    Turn on tv, power light blinks for a few seconds then nothing. The screen does power up but stays a grayish black. Occasionally pink stripes flash across the screen, but that is it. It sometimes turns on without any problem, but freezes and goes blank after a few seconds (20-30). Began having problems on 9-15-08

Ok so I had the "EXACT" same problem. I came here and read the posts. I ordered a new power supply and replaced it myself. It worked like a charm, and I know nothing about electronics. It was super easy. For anyone haveing this problem, just replace the powersupply. You don't need a TV repairman you just need to take the plastic back off your TV, and remove the second metal back and then remove the power supply and replace it with a new one. That's it.

I have an LG Plasma TV model 50pc5d-ul That powers up with no picture. Green power-on light blinks 13 times (staying on with the 13th blink).

Green LED flashes 13 times means power supply board is the issue. If you are familiar with the electronic repair, open the back and check if any capacitors are blown.. if they are bulgy on top, replace them. Attached link may help you in investigating the problem:

LG 42 LCD no sound or picture

This is probably bad capacitors on the power supply board. My LG 42LB1DR has a known problem with this and I replaced the four bac capacitors myself and saved 5-6 hundered dollars that I was also told that it would cost to fix. I fixed for under 10 dollars and about 20 minutes. LG knows about it but they dont really want to admit it. My TV was only 26 months old when this happened. The four capacitors are made by Samxon and are 2200uf @ 10v. They are junk so even if you have the entire board replaced for say $200 its just going to happen again. They need to be replaced with a different brand.
