I'm having more problems with my monochrome monitor again. A few weeks ago my monitor "died". Luckily a few people on the network informed me that all I had to do was to replace several diodes. I did that and it has worked fine. A few days ago the picture started to "shake". The entire screen vibrates, with the left side being more noticeable. I didn't replace the diodes in the monitor with the *exact* diodes, but the salesperson at the electronics shop said the ones I have will work. I think the differene is that the ones I'm using now have a higher voltage rating (??). Has anybody seen this problem? Is there a fix, or do I need to buy another monitor? Thanks in advance. vovut@prism.cs.orst.edu

My monitor has been on top of my Megafile 30 for over a year now without any interference. There are no other sources of interference around the monitor. The darn thing just decided to "shake" on day and hasn't stopped yet. It still works, but I'd *REALLY* like to get rid of the shaking. vovut@prism.cs.orst.edu

The SM124 is _extremely_ sensitive to magnetic fields. Even a small magnet placed next to the monitor will sometimes cause an annoying jitter in the display; a small flourescent lamp next to the monitor will cause it to go crazy. When I first got my ST the display sometimes jittered and it took me two months to track down the source of the problem. There was nothing in my office that made any difference, and no wiring buried in the wall, etc.; but the jitters got really bad whenever a guy on the other side of the building turned on his electric heater. It turned out that the electrical service for the building was on the wall _outside_ my office, about 1-1/2 feet from my monitor, and the heater was drawing enough extra current through the service to cause the problem. Anyway, try moving your monitor to the center of the room or something like that to rule out magnetic interference.

I had this problem about 3 years ago with my monochrome monitor. After three trips to Atari to get it fixed (they kept claiming that it was interference. Funny how it happened anywhere I took it, and anywhere I put it), they finaly replaced the monitor for me for free. I am not suggesting that they will always do this, but since I never found out what the problem was, I would be interested in knowing how it turns out. ------------------------------------------------------------------ Peter Santangeli -- Graphics Software Designer / Alias Strategic Research / \ Research psantan@alias.com / \_ Inc.
