Hello there,
I have a psu, bk precision 1550, i bought it broken from ebay, b1n60fh - dead, irf3205 - dead, s8550 - dead and two resistors, I replaced all dead parts, have voltage on the screen, can change the voltage, but no output and the on/off button won't respond when is pressed. My question, can somebody help me with some schematics, I saw this model have the same board with Tenma 72-8345, Manson NSP 3630, Voltcraft LSP 1363.
