Question about Flat Panel Televisions
Last week the power went out in our community for a few minutes. When it came back on the tv was snowy or fuzzy. We had a very clear beautiful picture before this.
We have it hooked up to Directv. The upstairs tv is very clear so i dont think it is the Directv.
All power cords are plugged into a power strip. I unplugged the main power cord to the tv and plugged it directly into the wall. This did not help, tv is still fuzzy.
I dont know if it is directly related to the power outage but it seemed to all happen around the same time?
If you check underneath the t.v there may be a button that you need to push. then you can use the remote to turn it on. took about 2 hours before I found it.
mine is located on the bottom left, right underneath the screen.

It's definitely an overheating problem if your plasma turns off by itself after a while. I would suggest to place a cooling fan near the back of it as a temporary fix.
There could be a power supply issue along with a Ysustainer board but in order to know that for sure, you should use a hair drier and blow hot air to the power supply and see if the TV turns off, if the time that the tv turns off is shorter when blowing hot air to the power supply; then is the power supply issue.

It related with Power Board(50%) or Y-Main(50%).
But, if you use the power bar with surge protacton, need to check
the power bar's lamp when the TV is turning on & off.

You are having problems with component failure. This could be a simple problem of over expanded solder connections that have expanded beyond the contact points on the board. This is reffered to as cold or broken solder joints. The other problem amy be actual component failure, such as bad capacitors or semi-conductor components. The unit need to serviced. You can call the Best Buy customer support telephone line at 1888-237-8289 and give them the model number of your television and the problem you are having. They should be able to give you a evalution and esimate of the repair costs. I hope this information helps you with your problem.

It can be that it has unstable power supply or the CPU/EPROM are getting scrambled by the noise and spike in the AC line, you may try better AC line conditioner to see if it will help.
