Hello guys!
Sorry for raising this topic again but has anyone managed to find the schematic?
Looks like it is a typical problem for this power supply - my PCB has the same failure: blown QX801, QX802; RX802, RX804, RX833, RX832, RX803 have infinite resistance; DX803, D804 are not functional; the area is blacken due to overheat at the moment of failure.
What DX803, DX804 are? Zener diodes or something else? Couldn't find anything appropriate marked as 'B3' and in SOT23 package. Digikey has this part: BZB84-B30,215-ND, is it the one?
Thank you very much in advance,
