Ok,
Working on a Air 2 wifi version. I changed the tristar and passed with the tester. when I power the board alone or just with the battery it pulls 1.5A steady. When I attach the screen it does this repeating boost cycle where the current jumps to 1.5 amps then to 0. Each cycle is maybe 5 seconds. Running out of knowledge and no schematic on ZXW.
