New to doing this.
I took the switch apart, and tested for shorts. There were shorts around the M92T36. I replaced the chip, and shorts went away.
I plugged in the amp meter on the USBC and there is no draw. Amps read 0.0. Turned the plug over, 0.0. With battery disconnected, all the same, 0.0. With battery still disconnected, I get 5v at the m92t36. I also get 5v on the USBC pins. The fuse is good, and the coil is good.
I am not getting anything on the screen of the switch, and no response with the power button.
I was wondering what the next step should be. I was thinking about changing the BQ chip. Any advice?
