Hello, I have problem with Delta GPS-750AB A PSU.
I checked almost all components on the PCB, desoldered and measured them.
The power transistors were desoldered tested with transistor tester.
All capacitors tested.
All diodes tested.
SMD transistors not tested.
The IC was blown TNY280PN, replaced
Also the resistor was blown is the blue one red arrow
on +5VSB I measure 0.9-1.9V jumping
What else to try?
