I have a PX-42VM5A and my Power supply is a PNT-426 (by Sanken Electric Co. LDT). Here are my specs: INPUT: AC 100-240V; OUTPUT: (there are nine outputs) +170v 1.6A; +60v 1.6A; +5v 4.0A; +2.5v 1.9A; +3.5v 1.9A; +7v 1.0A; +12v 0.5A; +12 v 1.9A and +6v 1.2A
I assume the part needing to be replaced is discontinued and there is no cross-reference for it thus the need for specs...if so:
The problem is the transistors, MOSFETs, most likely, that are used for high speed power switching. They're about .30 to 2 bucks but you'll have to order them direct as they've been discontinued. Just read the part number on the transistor and Google it. Matching specs on a discontinued part can be difficult.
