hi there,
I am trying to troubleshoot the ATX in question.
I have it connected in series with a bulb.
It randomly goes into startup trouble where the bulb turns itself fully on, only to work ok right after turnoff/turnon cycle.
I checked the primary side - caps capacities (including main filtering one), bridge, diodes, transistors, soldered off varistors. nothing blown.
the PSU is based on ICE3AR2280JZ, datasheet

Here's a video showing the behavior
- first switch on - short / loop
- second switch on - works OK
- third switch on - short / loop

I would appreciate some guiding hand as to where to go next.
