Hi guys
I'm working on some whatspower P222C power supplies. I have short circuits in either or both of the PFC mosfets and/or output transistors. I need to remove at least one heatsink to diagnose this but they are very hard to get to (the device screws) and there is this white sh!t everywhere on the PCB (which is double sided tracks at least)
Anyone can suggest the best way of working on this sort of thing?
