frame collapse. trace the wires back from the yoke to the pcb, look
for an i.c with at least 6 or 8 pins, probably heatsinked, or a pair
of transistors. start there. check there is a supply voltage, usually
between 20 and 60v, probably from a secondary of the big black line
output transformer. could be an open resistor in this feed.


Mine is totally dead.

well, have you checked for missing voltages inside? bad solder joints?
protection diode near 12v inlet?

thankies, I'll post the resutls in a day or so.
