I am finally getting back to working on this Plasma TV that occasionally shuts down.
I would like to isolate the power supply to be certain that it is where the problem lies. I have tried powering it up using 2 100V light bulbs as a load on the 60v and 80v rails to no avail. It doesnt attempt to power up unless it is attached to the Y-sus board.
Im guessing it gets some kind of ok signal from the VSS line?? Or is the
150W light bulb not enough of a load?
