hello guys,
noob here with dumb questions.
Got hands on PS Slim (EDM-041) with single beep no lights issue. PSU OK, with bench power supply board at idle draws 0.004A, at switch on (beep no light) draws 0.15A and goes back to 0.004. Been probing board and can’t find any shorts except one place I where resistance is 2.1 Ohms. I dont know what it’s responsible for. It’s on dual mosfet NTMFD1 SW legs, is this low impedance rail or it’s shorted? Nothing in it’s way except coil and 2 tantalum caps on another side grounded. Will UART show anything if its been no light ? Any help would be appreciated.
small update, UART scaner by The Cod3r shows this:
Error code: 80871055
