    I have the same problem. I've checked a few voltages at the PF-board(Power filter board). The 10.5 voltages were at 1.6 to .4 volts. The 24v is at 0.0 and the 5v standby is 0.0. I suspect the PF board. There is also a very light clicking coming from the PF board in beat with the louder clicking noise. I want to replace the PF board but I want to be sure. Anyone out their have any suggestions

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.
