The attached image is my failed 120VAC 1.0A -> 30VDC 0.5A power supply. I'm trying to figure out what I need to change to fix it without changing everything.
I'm not an electronics expert, but looking at the board it has a transformer, one big capacitor and two smaller ones, a transistor attached to a heatsink, 2 filters, some diodes and resistors, and two other components that I'm not sure what they are. I understand this is a fairly common design.
The power supply actually still works when initially plugged in. But once a load is applied, it shuts down. So I'm hoping that's a big clue what component is probably failed. I'm thinking it's probably one of the capacitors, or maybe the transistor, but what do others here more knowledgeable about these things think?
