I found that both of the fuses had blown despite being plugged into a surge protector with battery backup. I replaced them and one of the new fuses blew immediately upon power-up with a loud pop.
I removed the power supply (OEM part number 5061-3375), which was surprisingly easy - there's a pull ring on the back and it just slides out. Upon inspecting the interior, I found a burnt resistor. We decided to order a replacement power supply for about $250.
I plan to check the other boards in the system (ASC, AQB, CMP, and Communication Interface Board CRB) for secondary damage. I'm not sure how I'll gain access to the LUM Mother Board Assembly since it's deep inside the instrument.
Has anyone else encountered a failed power supply in these instruments, and did you have secondary damage to other boards? I've dealt with failed PC power supplies that resulted in dead motherboards, so I'm dreading any further issues with this instrument.
