Why does my 1710AV do this?

[LCGuy]

I have an AppleVision 1710AV display. As I mentioned about a year ago, it has a problem where the horizontal width goes out on it, and you have to literally belt the crap out of the display to get the image right again, for a few minutes before it goes again. I normally use it on a LC630 that has a Performa 5260 logic board in it, which can do 640x480 in 16 bit colour, or 800x600 or 832x624 in 8 bit colour. Today I decided to connect it to my LC475, and set the resolution to 1152x870. At 1152x870, or 1024x768, the display works perfectly, the horizontal width holds, the image is stable, and basically its like a new monitor. However, if I set it to any resolution below, it does all stupid on me. How is it that it only does this on the lower resolutions, and is there any way to fix it?

The exact seem thing happened to our old Packard Bell monitor.

I had a misbehaving Apple Multiple Scan 17 that required abusive treatment when the video got stupid. I finally decided to apply my considerable experience in fixing things to track down the intermittent using various long and highly insulated tools to mechanically probe while running the thing open and staring the red wire of death in the face. Well, I NEVER found the thing: when there are a jillion tiny parts close together everything feels the slightest PC board flexing. Hours later in a moment of clarity I realized this thing was calling to be recycled. So I Freecycled an excellently working Apple Multiple Scan 1705 Display, marked the old one "Known Bad" and shipped it off to the local computer recycling center.

Quality control at Sony (the monitor OEM) was not great in those days and out of a batch of 40, I recall returning 8 under warranty. I'm surprised that yours has lasted this long -- I scrapped one with similar symptoms last year.

Indeed...even back in the day I remember hearing about all the problems that people were having with the AppleVision 1710 displays, a road Apple indeed. I'm not going to scrap mine...at the right resolution, its still a fine monitor, so there's no point in scrapping it yet.
