I have my A3000/25/50 since 3 weeks. Last night, the screen began to be quite "jumpy" (it seems to move vertically). I tried to adjust the display enhancer but it didn't change anything. I wonder if someone has a solution (it's a very annoying problem and I don't want to lose my 3000 for 2 weeks after only 3 weeks of use). Thank you for your responses.

Skank | >skank@iastate.edu |Fast cars, fast women, fast computers... >Senior, Electrical Engineering |(not necessarily in that order) Francis, Are you using a 1950 color monitor? The problem you describe sounds like the one I've been experiencing (and been trying to solve) for several months now. George, I give, what's the problem? I've been in contact with Commodore Customer Satisfaction and _they_ don't know what it is. They say they are not even aware that such a problem exists. They even shipped me an advance replacement unit 'cuz my dealer can't help me, and it has the same problem. I've now been through no less than four (4) 1950's and they all suffer the vertical jitter problem. I've found, at any rate, that it's highly sensitive to temperature. Cool the room down, cool the monitor down with a fan on top of it, heat the unit up a bit by blocking off part of the top vents, and viola' - the problem goes away (or, at least, the symptoms subside). BTW: So far I've found Commodore to be one of the most responsive manufacturers I've ever encountered. Now, if they can only get me a less nervous 1950 :-) -- Jim Seymour | Medar, Inc. ...!uunet!medar!jseymour | 38700 Grand River Ave. jseymour@medar.com | Farmington Hills, MI. 48331 CIS: 72730,1166 GEnie: jseymour | FAX: (313)477-8897

I have notices that my 1950 has had similar problems sometimes. I have also noticed that if you fool around with the Vertical postion controls on the side of the montior, they might clear up. If this is the case it might be that the potentiometer that controls this is dirty or has some other problems. I have noticed the problem on many of the 1950's I have seen as well.

The jitter problem is a registered problem with the early 1950. If you have the problem your dealer should service it under warenty (ship it back). -- "The problem with the Eunuch's Operating System is that it has no balls!" - John Richter Amiga@ccwf.cc.utexas.edu .....Paul......

Your first course of action should be to return the monitor to your dealer which he should replace. A few months ago, I posted a way to "fix" it yourself, but this requires you to open your monitor. If you are desparate, I'll mail you a copy.
