While turning on the set, with the front button or remote--see if that line changes, (either from 0-3v. or more--or possibly the other way--3 to 0. it should be a noticeable, definite change.
It is does NOT--then you likely DO have a bad signal board.
If it DOES_-then something is wrong with the run supply on the PS.
You can VERY easily have full standby--but still have a run supply problem.

That's the strange thing... I have no power on or off. If I plug the unit in, the LED backlights come on though the power on/off switch does nothing. And of course if I unplug the unit, the LEDs go off.
