Hi I have purchased x4 non working switches which all take a good charge but won’t power on. No water damage, all BQ, MT and P13 chips seem to work with no shorts around them. I tried using a known good screen but still won’t turn on. I’ve replace the P13, BQ and MT chips on one of them but still no charge. Any ideas?
Ist dies eine gute Frage?

Hi! I had this same issue with my Switch. I tested all of those chips and they seemed to work fine, but it still wouldn’t power on. When I tested some of the capacitors on the back of the motherboard, I realized that the CPU on the Switch was shorted. If the CPU is shorted, there is no way to fix it other than replacing the motherboard.
