So a couple weeks ago my monitor started having periodic flashes where it seems to lose its sync for an instant. Today it started doing this thing where the picture shakes and shrinks while losing focus for a moment. It will go through a spell where it does it for about 5 minutes and then it stops, then again sometime later. It seems like it's dying.
The thing that bugs me though, is that otherwise the picture looks great. Colors are still great, and sharpness is till perfect (besides when it is acting up). Does anybody know what exactly is failing? Are there any adjustments I could make to the flyback to get a few more months out of this thing?
I even read somewhere that stuff like this can be caused by bad solder joints. Should I go in and look around for some bad solder spots?
