Bad screen…
Posted by: jimhent on 2025-03-09 15:54:40
Hello everyone! hope everyone is well. I have an issue with an old Powerbook Duo 250. It has an active matrix screen, I believe it was the first to have one. I have an issue where after the screen stays on for a while it starts to fade to Black. I fear of course that there is no solution to this problem, but has anyone had any experience with this? Thanks.

also known as "lcd tunnel vision", you'll find more info if you search for that

... might also be failing CCFL backlighting - in a dark room is the display still illuminated when black? If not, can you see an image shining a torch at the display

I have a 170 that somehow doesn't have tunnel vision yet. I'm beginning to think leaving it in the same room as my orchids that need 45% ambient humidity or better is pushing my luck...
