Hi Art,
Did one with the same symptoms.
It was the Vert. chip.Shorted.
It triggers the protect-shutdown ckt.
I have the factory print on disc if you need it.

This is the first one of these we've ever seen and we have nothing on it at
all. It's a flat-screen DVD combo, and when you try turning it on, it goes
through three startup attempts (you can hear kind of a click from the power
supply area) and then quits.
Sitting in standby, there is 115V on the collector of the horiz output
transistor, and I spotted two three legged regulator IC's that had the
proper 8 and 9 volts on their output pins.
Does anyone have anything on this one? We'd like to get it out of here.
Thanks, Art
