Powerbook 140 screen contrast black
Posted by: gijsmans on 2020-10-08 23:34:14
Just acquired a PowerBook 140, previous owner was an old lady. Set includes everything including the original bill. Adapter the was failing, opened it and needs recapping, serious leaking. Bought new 7.5v 2a adapter. Boots from original System 7 install floppy. But screen is black, backlight is fine, looks like contrast is max or min. Contrast slider does not have an effect on contrast. Recap or easier fix?

Thanks, send Macintosh Portable capping to a handyman. Will try this thing myself. PowerBook 140 state is amazing.
