I am sure this has been posted about before, but my lack of technical expertise doesn't even know what to search for.
I have an original mac - Last week it worked fine. This week, when I turned it on, I got nothing on the screen. The boot chime sounded as normal, and when a disk is inserted I can hear the disk drive reading it as normal.
I opened the machine and messed around with the brightness dial on the board itself. If both it and the "normal" brightness dial are turned all the way up, I see diagonal white lines. If I kind of touch the "Voltage" dial on the board (the small screw adjustment), I catch glimpses of the blinking question mark through the diagonal white lines.
Any ideas what has given up the ghost here and is it fixable short of a complete replacement?
