Hello again, I've got another odd problem...I seem to get a lot of those lol....anyways, here is the short version of the story...got this monitor when I got my system 256...was paying for the sys 256 so didn't care about the cab but figured since it was a vga monitor what the heck I'll keep it....
obviously that was before I had read all the threads about this model here lol!
So anyways, it had been working relatively well but has recently developed an odd problem....well there are several problems, but I think they're all related so let's just tackle the big one for now...
first just let me say that the monitor works...it powers up and there is picture...
the screen will, for lack of a better way to put it, flicker slightly...if the screen is blank you can see little balls of light flash momentarily in random places and occasionally a line will momentarily flash all the way across horizontally...as this happens, if there is a picture, you will notice that the focus seems to go slightly blurry, then snap back into sharp focus. This happens constantly, not sporadically. I have also noticed a sort of faint buzzing noise, which is not constant, but seems to randomly happen for random amounts of time...as best I can tell, this seems to be coming from the flyback...
so, after reading through 14 pages of threads about problems with this monitor type let me tell you what I've done thus far...
I've replaced the major caps, I've reflowed solder on both the main board and neck board, I've tried all available adjustments(including factory mode), I've tried different power supplies, I've tried different boards and systems, I've tried no boards or systems, I've tried vga mode vs cga/ega mode, I've deguassed, checked my grounds, etc, etc, etc. Basically all the very basic stuff I've checked and the problems persists...
Soooooo...I'm thinking based upon what I've read that this is a flyback problem and replacing it should be the obvious fix here....does that sound correct to you guys?
At any rate, looking for opinions, verifications, input, etc. and as always, am extremely grateful for any and all help you guys might care to offer...thanks!
