Sounds like your power supply is causing the problem. Unplug the TV wait 10 minutes, look in the back for a red button (circuit breaker) push it in. If this does not work you have a low voltage power supply fault.
The first step here is to isolate the problem. You need to know if it is in your TV or DVR. Unplug your TV from the DVR and connect it directly to the wall outlet. Then connect a TV antenna, or a small thin wire, to the F connector on the back of the TV (this is the threaded connector - where you plug your cable). Try searching for some air channels and see if you get any channels at all, and post back.
This may denote a proble in either your switching powers supply or your Horizontal section derived high voltage power supply. These are both very dangerous sections in your television. My next question is important; do you have a background in electronics? If not I would not advise you working on this problem yourself and that you take the TV to a repair shop for servicing. If you do have some background in electronics, I would like for you to make the following obeservations:
What was the TV doing (it actions)prior to it going out?
Did you hear any sounds before it went out like buzzing or crackling?
What do you hear when you try to turn it on now, clicking?
These questions are just to develop some background into what might be happening to your set.
Hey Jim, The high voltage protection circuit has gone out on the D-board and will need to be replaced. The fuse to the power supply is probably fine. A good repair tech shouldn't charge over $125 for this and it only takes a couple of hours. Let me know if I can be of further assistance.
