out of circuit and dischargedHow did you measure the capacitor? Was it discharged first, in-circuit?
What type of meter did you use to measure it? Ideally, you need to measure the ESR. The capacitance is slightly lower than what it should be.out of circuit and discharged
you mean those two resistors?You will need to trace the resistors that form a potential divider for that IC. Watch the video above, you are looking for the equivalent to R204 and R205 connected in the same way to IC1 on your board.

yup got another one lol, the old one would make good spare parts don't you thinkThe same one you have been repairing here:

ok i changed the big cap and measure the voltage under load and now everything is fine , although i don't understand what would be the relation between the big cap and the output voltages , someone told me the cause might be the OptocouplerPossibly, you need to trace if they are connected in the same way as the resistor numbers I mentioned above in the video.
There are two other resistors close to the KA431 which could also be the potential divider for it.
did i bother you in any way BluejetsNow now, no need to yell.
Not an accepted practice .
