So I had a customer bring in his device with water damage. Very clean. NO chime, No backlight. Only real corrosion was on R3201 on the PP3V3RHV pad which was entirely gone. I ran a Jumper from the thunderbolt connector pad, to the replacement resistor and tied it all back in. But I can not for the life of me find where this thing is shorting to ground on the PPVCC rail. I put 1.5v to the rail but nothing got hot. (not sure anything will at that low voltage.) Am I just stupid and don't know how a multimeter works?
