I need help identifying and finding a pin out for IC31, DAP017A (PFC I think) and IC32, DAP015A (PWM controller I think). A schematic would also work but from my searching on this forum, they don't seem to be available. I have a self drawn schematic which I've attached below. Both parts seem to be in SOIC16 packages. I can't seem to get any PFC boost out of this unit even though I have changed all the bad components I could find:
F1 open
Bridge rectifier, BD1, T4KB80F is shorted.
Q1,Q3, SPA07N60C3 open.
Any further troubleshooting tips would be welcome.
