I bought an LG452T-TF monitor about two years ago and the DVI port seems to be busted. The problems first started about a week ago. After waking my computer up from sleep the monitor only showed grey static or flickering. I initially tried different cabling to rule out a bad cable with no success. I gave up frustrated and the tried again the next day and it worked perfectly with the original cables. Then a few days later it died again and it's been about a week with no luck trying different DVI cabels. However, it does work via the VGA input. Since it died, resurrected, died again and given that the VGA port works I've concluded it's probably a loose or broken DVI input port on the monitor. Since LG doesn't seem to want to honor their three year warranty (no word from them) and I don't really want a new monitor (most new affordable 24" monitors are all 16/9 instead of 16/10) I'd like to try to fix it myself, but I'd like some advice before I begin as I've never repaired TV or a monitor before.
I'm hopping someone can pass on some advice about how to fix it. Specifically I'd like to know how difficult it would be, what tools I'd need, and if there are any general how to guides you could point me to.
