I have the same set and had the same problem. I repalced the DT board and now its fine except I have no video signal. I get sound all day long!! I also have the on screen menu to make adjustments but still no video from any input.

First unplug the set for about 10 secs and plug it back in to force it to reboot its firmware. The on/off switch does not do this. It takes about 10 seconds for the reboot to occur so wait that long then turn on the TV with the on/off switch. If that doesn't work try a factory reset. Turn off the TV. Open the front door on the TV and HOLD the OK button down and then press and HOLD the power button at the same time for about 2-3 seconds. Hopefully you will see a screen come up and say Self Check. The TV does some built in tests and then goes to the menu screen like it came out of the box. You will have to reprogram all your stations and settings.

This may be a power supply relay actuating, What I would suggest is taking this set to a TV repair shop since the attempt to try to repair this yourself may lead to further complications.

There are some factors of this kind of problem.
First you could have a failure in the power supply. Next could be the main board. Lastly you could have a problem with the panel itself, this would mean a new set for sure because the part cost is more than a new set.
However try troubleshooting the problem before spending money on repairing or replacing the television. Possibly you can restore the picture and sound to your television ...
Verify the TV is powered on by pressing the power button on the TV's remote or the front panel of the set. This may seem like an obvious step, but many TVs are equipped with a standby light that will illuminate if the TV is turned off, making it appear that the TV is on when it is not.Cycle through the TV's video inputs to verify that your TV is set to the right one. For instance, if you are attempting to use a digital cable converter box that is plugged into the Video 1 input and the TV is set to a Video 2 input that has nothing plugged into it, the TV will not display any picture or sound and may even say "No signal" on the screen. To cycle through the inputs, use the input selection button, typically labeled "input," "source," "TV/video" or the like.
Re-seat the video and audio input connections to verify a loose cable is not causing the TV's loss of signal. If you have a coaxial cable connected from your wall cable jack directly into the TV, it may have come loose thereby eliminating all picture and sound on the TV. Locate the connection cable or cables of whatever device you are attempting to watch and unplug them from where they plug into the TV. Plug them back in and check for a signal. If there is still no picture or sound at this point, the best option is to contact technical support for further assistance.
