[Repairs] screen stays grey

[Daniel Fuhry]

Hi Luke,

I checked the screen connector but it looks fine.

Via serial I got into the open firmware prompt:
 +
Forthmacs
Type 'i' to interrupt stand-init sequence

USB2 devices:
/pci/usb at f,5/device at 0,0
USB1 devices:
Unimplemented package interface procedure

after this message it just keeps rebooting.
I tried to intercept by pressing "i" and typed probe-pci probe-usb
flash u:\q2d16.rom
I got an reading u:\q2d16.rom message but it isn't actually working.
(AC and battery are connected)

I give it another try tomorrow.


Thanks

Daniel
