Re: Sony Trinitron KD-28DL10U red, green, red, green OCP fault
Check and see if you get the +135 volts on the main board near the flyback, it should be marked, if not check it on pin 3 of the flyback transformer or C525.
If it is there for a short time before shut down the power supply is working and you don't need to check in that area.
I suspect that it is a is a shorted component somewhere in the high voltage/horz. deflection circuit.
So is there +135 volts? if yes
is there the +200 volts on c513 or cn508 pin3 ?
