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?

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.
