MacBook Pro Retina Early 2013 820-3332-A Powers on bot won't load any OS

Even with external SSD it tries to load but shutsdown right after, holing the Alt key at the start brings up the drive boot menu but as soon as you select any HD including ASD one it shuts down, sometimes when it does load the OS it gets really really hot.

Reflow/resolder U8900.
Change it, if still the same.
After that, only remains GPU as culprit.
See if pass all ASD EFI tests.
