Sorry the foto service has reduced the resolution. Reuploaded “pastebin /nDTa85at”.
I came home very late today, I’m too tired to disassemble the switch for more measurements at the moment. But here are some answers:
I thought there would be different modes for charging. Max 500mA for standard USB, max. 2A for classic 5V USB power supplies, and the new increased voltage modes.
I have now connected my working Switch to my 5V Anker supply, it takes 1,44A in stand by mode (not switched off).
I connected my working Switch power supply to the defective switch, I still get the blue screen. At the moment I don’t have any solution to connect my multimeter into the USB C connection. Because of the continuity check across the capacitors I still think it must be a hardware defect.
I have also tried to enter the RCM mode (it’s a first generation model, so it should normally work), but I still get the blue screen. By the way, I know for sure nobody tried to run homebrew on this switch, so it should not be a firmware/software problem.
Thanks!
Simon
P.S. as soon as I can include fotos I will add them directly for reference.
