It looks like it was a mistake to let a friend borow my Sony Trinitron monitor (GDM-400PS). He used it for about 6 months before getting an LCD, then stored it in a spare bedroom. I went to pick it up today and when I got it home, glad to be back to my dual monitor setup, the image was jumping back and forth vertically.
I know its a problem with the monitor itself and not the video card or cable. When the monitor can't detect a signal, a "no input" box appears on the screen. Even that isn't stable. The only external controls on this thing are reset to factory defaults, auto screen center, input to choose VGA or BNC connections, menu and arrows to adjust brightness/contrast and move through the menus.
The input and auto screen center on the left of the control panel work, but the other buttons don't seem to do anything. Its sitting right next to its twin and there's never been any problem with interference between the two or anything else nearby.
Am I sh*t out of luck or is there some chance to fix this thing? Even Sony CRTs aren't that much, but once you ship these monsters they aren't cheap. And I loathe monitors with the DELL logo even if they are the same underneath. HELP! I need my expanded desktop back!
