Gateway FDP2485W DVI in broken

[HeezDeadJim]

I've had this monitor for maybe 6+ years now? I used to use the DVI input, but a I think a PSU from a computer might have overvolted and fried something to the monitor. That happened 3+ years ago. I've been using VGA since (the only difference I see is no "pixel mapping"), and it does very well with "auto" syncing phase and getting each pixel to where it needs to go. In fact, it does such a tremendous job at it, there really isn't any difference that I can see with the VGA input....and I do photography so color accuracy is a huge deal to me (I calibrate all of my monitors).

The only reason why I care about trying to get the DVI input to work is because I have a new video card that seems to introduce noise when I play games on it. It gets worse over a few minutes of playing and I have to use the "auto" button to re-sync to a clear picture (it looks the same when older TV's were losing a signal from the bunny ears).

I've opened it up before to see if there was any fuse or burnt cap for the DVI input, but honestly, I don't know where to look. If need be, I can open it up again (kind of a chore since it's quite heavy) and take photos inside if one would like. To be clear, that is the only problem with it. No power issues, no button issues or anything like that. The DVI input refuses to show any signal.
