820-00045 no liquid damage. takes charge, touchpad clicks, blank screen

[kevinklinkmuller]

have a 12 incher here, takes 20V on the charger and current is going in. In fact the touchpad also clicks. I tested with a known working display without any luck. These boards are super weird, where do i begin?

Start listening some classic for these boards... "Return to Sender"

Did you test external video at least?

 

[kevinklinkmuller]

Hahahaha oh no!
I just realised that my initial assessment of liquid damage might be wrong. there's liquid (or oil) all around the underside of the board where it sits on the seal.
Yes external video I tested as well, no sign of life (except the click on the trackpad)

Dead CPU as always

 

[kevinklinkmuller]

Really?? Is there a way I can confirm this?

 

[JohnB8812]

It?s a 12? MacBook. That?s all the confirmation you need...

If customer needs data, try reflowing or reballing the CPU. If they don?t need data, throw it in the trash
