    Monitor sounds

    My Sync Master 930a analog monitor is starting to make a strange sound. It sounds like short bursts of grinding or static. I'm told that it does not need degaussing as it does that automatically each time it's turn on. I have 6 buttons at the bottom of the monitor but I don't know which one to select if the problem lies there.

    Can someone please tell me what the noise means and what I can do to correct it? A friend told me that the sound means that someone near to me is using some kind of electrical equipment.

    Re: Monitor sounds

    If it sounds like short bursts of static coming from your monitor, you probably have short bursts of high voltage discharge in your monitor - not a good symptom.
    This has nothing to do with degaussing and has nothing to do with nearby electrical equipment. If the latter were true you would be hearing the sound from the speaker(s). The most common reason for such discharges is dust/dirt inside the monitor at places where the high voltage runs. If you are very comfortable with electronics including high voltage practices you could go inside the monitor and try using a compressed air can to clean things out. If you are not experienced in these matters then NEVER open up an analog monitor. The voltage on the end of the CRT (cathode ray tube) is really high, in the neighborhood of 25,000 volts, high enough for the electrons accelerated by this voltage to produce X-rays.

    The other main reason a monitor may act this way is dielectric breakdown. If this is the case what you are hearing is just the beginning of a complete collapse of the operation of your monitor. Even if it is simply a HV capacitor failing, it makes no sense these days to try and get it fixed.

    I see a new LCD monitor in your future!

    Re: Monitor sounds

    I was so afraid that would be the case, but was hoping that a repair shop was in my future. It's a bad time of year to have to go to the expense of purchasing a new monitor, but I guess I will have to bite the bullet.

    I'll probably stick with Samsung, and take the next step up to a larger screen. I've got a 19" probably shoot for the next size.

    Thanks for the bad news right at Christmas time.

    Re: Monitor sounds

    Is this happening often?
    Loud?

    IF you are near enough to a source for a new tube, why rush out and buy a new one right away?
    Haste makes waste.

    Re: Monitor sounds

    No, Viking, it's not happening often, just about every 30 - 40 minutes or so. The sounds not loud, more like static.and lasts for about 1 to 2 seconds.

    I don't understand what you mean by 'source for a new tube'. Please explain.

    Re: Monitor sounds

    You can wait and replace the unit when (and if) it fails. This could easily work out to be after Christmas. So the best approach, in my opinion, is to use the monitor as is and start spending some time looking at possible replacement monitors and good buys on them. There are a lot of choices out there and the single biggest piece of advice I can give you is to try and view the monitor working in a store or office to decide if you like its visual attributes: Is it bright enough, is it easy to read ( characters crisp and big enough) , does it have strong front surface reflection, is the package and its size suited to your tastes. The operating parameters can be read from a spec sheet (# of pixels, contrast, bits of grayscale, viewing angles, does it have usb ports or speakers, ...etc). You do not have to see these parameters to make a choice, but the viewing characteristics you have to SEE.

    I meant a CLOSE sourcestore for a new monitor so you could get a replacement quickly enough, <big>IF</big> it did suddenly go down the tubes. <img src=/S/frown.gif border=0 alt=frown width=15 height=15>

    Re: Monitor sounds

    Good idea. I will take your post with me (after Christmas) when I go shopping for my new monitor.

    By the way, is your first name Paul? Mine is Gloria, glad to meet you.

    Merry Christmas to you and yours. <img src=/S/music.gif border=0 alt=music width=97 height=29>

    Re: Monitor sounds

    I'm going to wait until I move back to New Jersey, on Jan. 15, 2008. I'll be living across the street from the Cherry Hill Mall and in the same vicinity there will be lots of computer,and furniture stores from which to make my selection. I'll be in the market for a large flat screen TV and a large flat screen monitor.

    I finally settled the case against the store that caused me to fall and break my elbow and my knee. Santa Claus will indeed be good to me this year..

    Re: Monitor sounds

    I am more than pleased to inform everyone that once I updated the driver, the noise has disappeared. I hope this solves the problem and I have another year using the monitor.
