Hey guys.
13" 2017 4 port, powering on and stuck at Apple logo on first inspection.
Discovered customer severed trackpad cable while attempting DIY battery replacement WITH BATTERY CONNECTED and fried L4500 (charcoal!).
Full short to ground on PP5VS4. I removed L4500 and cleaned/dug around the roasted section and all layers seem to be clean and seperate so I suspect the short is somewhere else.
Any suggestions on a likely culprit on this rail, any "usual suspects"?
Just thought I'd ask before I inject voltage on the line since Banjo (u7800) is on this rail and I don't want to fry him...
Cheers,
Mick
