Hi, I bought 2 Nintendo switch that weren’t turning on. The first one had already been opened and I think they tried to reflow the cpu (I will keep this one for pieces).
It is with the second one that I am having a hard time finding where the issue is coming from. When I first opened it there were some signs of liquid damage around the BQ chip and on the other side of the board, under the charge connector. I cleaned that up and then went to check for shorts around the BQ, M92 and PI3USB chips and found none.
I reassembled everything and no backlight, no screen, no sound coming from the console. Fuse is ok, 5V 0.4A constant, charged the battery externally and still nothing.
I tried to put the switch in rcm mode, it is recognised by tegrarcm and I can inject payloads but the screen doesn’t light up.
I also tried the screen from the first switch but didn’t change anything.
I don’t know what to do, so I was wandering if anyone had the same problem or maybe knows where to look ?
