I recently attached another monitor to my NetBook; it worked fine for a few hours.
I turned it off a while ago. I then tried to turn it back on, and all it does is a weird noise, sort of like a hard-drive seek, but higher pitched and faster (sorry I don't really know how to describe it).
The image appears, the backlight flickers a little, but then the monitor goes completely black (backlight shuts off) within about 2 seconds. If I attempt to turn it off and on again, it does the exact same thing.
I don't think it's a power issue, because the green light indicating that the monitor is on is still lit, even after the screens turns black (I also tried switching outlets and AC cables, but it didn't help).
Any ideas as to what might be causing this and how to fix it if possible?
The monitor is a Sony LCD SDM-S75A.
