    Four months ago we lost a 17 inch monitor suddenly...it started popping and suddenly went black (like an electrical short).

    Now this monitor is starting to jitter and sometimes pop, and the desktop images are keystoned (larger at the top, compressed at the bottom). The margins have been set to be parallel, and all setting have been adjusted in order to try to correct the problem.

    Yes, we degaussed.

    Are we about to lose another one?

    Why doesn't this happen to our old junky computers?

    I never had problems with monitors. I wonder what could cause the problem.

    Maybe it's something to do with the electrical current, have you checked it recently to see if it's properly grounded? You can get a thingie for cheap to check it, that you just plug in.
    Also, are you using a surge protector?

    Yes we are grounded and, yes, we are using a surge protector. I am suspicioning dust build up within the monitor and am waiting to hear from the manufacturer to see how far we can go without voiding our warranty.

    Monitors go out. I bought one, had to replace it a year later--just after the warranty went out. Then that one went out--just after the warranty ran out.

    Yikes! Is that how yours went? Popping, jittering, distortion, and then ZAP?

    Often, popping and jittering is simply a loose connection. Make sure both ends of both cables (the one from the computer, and the power to the wall) are all fully in place. If it still jitters and pops, it is likely a loose power wire inside the monitor and I'd check the ones directly attached to the power socket first, adding a little solder as necessary. As for the distortion, there are a bunch of little adjustment screws inside the monitor you can tweak - BUT WARNING: opening your monitor case can be dangerous, as even unplugged the monitor will still have a very large stored electrical charge at the rear of the display tube - you could get injured if you don't know what you're doing.

    Im recalling my brothers old monitor -

    Buncha questions

    1. do you have it near another major user of electricity something possibly unshielded or less shielded?

    2. How old is this computer? More specifically the video card - Ie is it capable of handling anything anymore?

    3. Software faults can often cause what appear to be catastrophic hardware failures - Are your drivers compatible with the monitor type? Or have you done what I did and found a driver that isnt company code but doesnt conflict with other things

    4. Often conflicts in other areas such as sound can cause display problems. Have you changed anything about the computer except the monitor recently?

    5. Often having a bunch of near worthless resident memory programs can cause problems with display. How much stuff do you have pre-loading?

    6. If you actually hear physical sounds refer to previous post by other guy

    I ran across this same problem with a client about two years ago. It ended up being a problem with the fan on the cpu. Who would have guessed? It was evidently dirty and once it was replaced it was fine and never gave them another problem.

    I also had a similar problem and it ended up being my UPS. I replace it and everything was hunky dory.

    Another option that you may want to consider is that the governement is monitoring your usage of your computer with microwaves that could be interfering with your monitor. :rolleyes:

    Check your owners guide for the term 'Degauss', &/or go here to read more on what I suspect may be your problem.

    Degauss

    ...or here to read much more than you ever wanted to know about 'Degaussing' your monitor.

    oops! just read that you degaussed, sorry. I've no idea past that, but I just read this...

    "On rare occasions, there may be geometric distortion caused by magnetic fields as well without color problems."

    Hummm...? Do you have any really, really big magnets nearby? [​IMG]

    We appreciate all the suggestions. Margie raised the manufacturer on the phone today and they are sending a replacement monitor. The tech guy is confident that it is a faulty part on a monitor with a three year warranty!

    If this pans out the way it is promised, I highly recommend KDS brand products. No muss, no fuss, just send the thing back home. You gotta love that! [​IMG]
