Hi im new here and i search the powerfull machine for Debian and MorphOS.
So i got two A1138, but both got a defect.:rolleyes:

First one : when powering the screen stays black the fans run full blast the led stays on no chime.
Second one : chime the lcd flickers, and then the Powerbook is off.
I renewed the cooling paste and clean the fans, but nothing.
no obvious damage visible on the mainboard.
Anybody a advice or anybody has successfully repaired such a machine?
Thanks
