EXPERIENCED-We have been building labs, equipping labs, and supplying lab equipment parts and service for over 20 years. I replaced it with the current replacement part and had to insulate the back of the the MOSFET from the heat sink using Kapton tape.1. MOSFET visually looks fine, got me there. Resistance measuring of the MOSFET shows 3.5 ohms from the gate to Drain as well as the Gate and Source. More board probing and I found that the diode is input protection from the MOSFET on the lower right of the board. Replaced the diode and fuse (3.15A 250V) and reinstalled the board. It is not so burned to be able to read that it is a US1M diode (Got lucky on this one), it seems to read funny it passes diode test on my Fluke in both directions. I noticed the signs of a hot component between the 2 heat sinks on the bottom right.next to the 2 red film capacitors. That said the board is broken, it is more than likely that I cant possibly break it any further. this is a little weird since the status LEDs on the board clearly show that the 120VDC is working normally. A little reading of the service manual and the section of the PDB that has the blown fuse is the 120VDC section.
