The most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

I have a Sylvania 42 inch Plasma HD TV. It is 3


Hello

Before taking this to a local repair person, I suggest you check with your cable provider. See if they are having trouble with their HD transmission and then have them test your lines. Out here in Arizona with have constant problems with HD due to heat, rodents and poor installations. Your DVR only recorded the problems that were on your set. If these prove fruitless then take the TV to a reputable repair person.

Good Luck

I had the same issue. Turned out to be a blown capacitor on the power board.

Sylvania 6842PEM


Have fixed a bunch of those as a Sylvania ASC. There is a small ceramic capacitor on the main power PCB that has ruptured. It must be replaced with a different part, a special type of capacitor, or it will just fail again. Sylvania had recommended replacing the main power PCB rather than repair because sometimes there was additional damage on the board, however replacing the capacitor fixed every one that came to us. I preferred that because some electrical voltages have to be adjusted if the circuit board is replaced with a different one.
