leftmost column on the screen are strangely compressed. Their height is normal but they are noticeably less wide than normal. After a few minutes the effect goes away, and all characters look normal. Can anyone tell me what causes this and/or how to avoid it? Thanks in advance.

I noticed the same effect when my 520ST+ at work got a SH205 harddisk. Whenever I switch on the SH205 before the ST the effect appears. However, when I switch on the ST before the harddisk everything looks as it should. So this is what I am doing: 1. Switch on the ST 2. Wait until the desktop appears 3. Switch on harddisk and floppy 4. Press reset to boot from harddisk On a ST with built-in floppy this procedure would require a boot from floppy as you cannot switch it off separatly. Ok, the whole thing takes a bit longer than a direct harddisk startup but I couldn't stand that nasty monitor look for hours.

First, you could have a defective component in the horizontal sweep circuitry that gets a bit better as it warms up. One way to track down such beasties is with a can of "freeze mist" (assuming you want to fix it yourself). Another thing that perhaps the horizontal centering control is near the edge of it's useful range. The way I adjusted mine was this: Turn the horizontal centering control in one direction until you notice a bit of folding (characters getting squished). Back the control off 'til this just disappears. Note the position of the control. Now, turn it the other direction and watch for the same thing on the other side of the screen. Back the control off again and not its new position. Move the control exactly between these two points. If the resulting picture is not centered on the screen, then use the centering rings on the back of the yoke to correct it. This adjustment should be done when the monitor is fully warmed up. If you do this adjustment, and the folding is still present when the monitor is cold, then you'll need to track down the defective component. I can provide more details if you like; they're a bit tedious, so I hesitate to post them. Good luck! -- Farrell T.
