Re: MACKIE PPM608 repair

Hi my friends. I need your help with this power supply...

After the replacement of a sorted D24 and some electrolytic capacitors with optical problems the power supply don't turning on. Also I don't have any ticking or something else... I have check all Mosfet and diodes and they are OK.

I measured the power voltage when I turn it on and in the drain of Q1 and everything is OK. But in the drain of Q2 started from 150 Volts and dropping to zero 0 after few seconds.

I can't understand what is going wrong... Please...
