I've had a Sony Plasma TV for just under a year, and a few days ago it started going out on me. It's connected to a DVR box, and every 1-10 seconds, the screen goes black. The sound is not interrupted and the power does not actually shut off, it's just the picture that is affected. The TV is connected to a DVR box and has external speakers. Do you know what could be causing this and if it can be fixed easily?

I had the same problem with a Sony tv a couple of years ago. The cable connection was going through the VCR, then to the tv, so we thought we could try making a direct connnection, and the lines went away! I'm not sure if this is your problem, but if so, this should do the trick.
If not, call a repairman, and they may be able to help.
Hello. You probably did not have that tv plugged into a surge protector. When the power was restored, a surge came through the line. A power surge is a spike in voltage above the maximum a tv, appliance etc. can handle of 169 volts. They are very brief, usually lasting millinths of a second. Power surges can vary in duration and magnitude, varying from a few hundred volts to several thousand volts.
That said, now what do you do. If the tv is under 3 years old I recommend that you take it into a local TV repair shop for a free estimate of repair. If it is older than that, I would not repair, just replace. J.
The TV is under a LG factory 1 year warranty.
Unless you bought a refurbished unit which has a 30 day warranty.
Contact LG @ 1 800 243-0000 for warranty repairs.
Be sure to have the...
Date of purchase
And Product code.
The information is on the back of the TV or on a small white tag
on the side of the TV.
the red blinking light usually has a pattern that gives you a code to the possible problem. Maybe you have a bad power supply board. You have to open the panel and do a few tests on the power supply's outputs to be sure. It produces a variety of voltages for different parts of the tv ie. the plasma display panel and the audio system. The components supplying power to the audio system may have failed a year ago and recently the pdp.
plasma tv's are expensive to repair, most of the time you can get a better tv for the same price. You can reduce that cost by learning and troubleshooting it yourself.
It could be the LVDS cable that is connected between the logic main board and the main board, sometimes this cable is too short and comes loose from one of the boards, it could also be a sign that the logic main is going out or the panel itself is shorting out
