Question about Televison & Video
SOURCE: Panasonic TV Shuts off by itself
I had the same problem , Good sign of a cold solder or cracked trace.
On my PT51HX41 after a long check with a magnifying glass I found the problem on the main board just below the AC daughter board there is a Blue rectangular box (relay R801) and it had two cracked solder joints.

Your TV most likely has one or more possible problems.
Problem #1: Convergence Chip Failure ( common problem )
Here are some of the most common symptoms and example photos of a convergence problem
Here is a quick test....
Using your original remote go-to the tv settings then goto the convergence section.
Try to adjust the red and then the blue convergence.
You should be able to move them up, down, left, and right.
If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.
You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

My system is doing the same thing... runs for ten minutes an then no piture and no sound, I just get a blinking green light.
I was thinking heat was the problem, I opened it and vacumed it out. This did nothing.
Now , is it the powersupply or the lamp? Would a bad lamp also cut the sound?
