The problem with this model is the large parts due to poor wave
soldering. Locate the transistor Q605. Using a
small wattage soldering iron melt the solder and add a little solder to
all the large parts in the area. Small wattage = 15 to 30 watt. Stay
away from the surface mounts they are not the problem. I resoldered the
following: D647

These parts are
located on the main board, the one the power cord connects to.
Carefully press the clip on the left side of the board (as you look at
it from the rear of the tv) carefully pull the main board back and out
of the rails. You will find the parts on the right side of the main
board about 2 inches over 2 inches down.

Try this: Turn it off, disconnect everything from the set (speakers, DVR, etc.). Unplug it from the wall, push the on/off button and hold it in for a least sixty seconds. Hook it all back up and it may have reset. No guarantees but it has worked for me.
