    This is a pic of what I mean, the computer monitor shows a good sharp
    picture, but it is all squeezed up narrow, and the controls to adjusted it
    change, but don't change the picture. my guess is that its got to do with
    the magnets that pull the picture out.. any idea as to how to fix this???
    what I should do.. or anyone recommend someone / somewhere that would do it

    A friend of mine had this happen to his monitor. He used to be able to fix
    it by banging it a few times, but that stopped working after a while

    Apparently it was caused by cheap, unshielded speakers he had next to his
    monitor. It wasn't worth fixing, they told him.

    Looks like it Could be set at a refresh rate the moniter can't handle.????

    Who was they? Sounds a bit suspect to me.
    Stray magnetic fields from speaker etc cause discoloured areas because
    the electron beams been bent and go thru the wrong hole in the shadow
    mask. It is fixed by deGaussing. (and moving whatever is causing the
    magnetic noise further away from the monitor).

    This is a volatage problem I think, the electron beams are not being
    bent far enough horizontally.

    Refresh rate is at 60, so I don't think that that is likely.

  7. Last time I had a problem like this, rolling the monitor down the flight of
    stairs helped alot... for my mental wellbeing. :)

  9. Ew. Headache city.

    IIRC current OSH guidelines state that the refresh has to be at least 72Hz

    PC isn't it? At 640 x 480 60 Hz is just about right IIRC.

    yeah same thing happened to my brothers monitor - horizontal sync went out.
    probably cost an hours labour to get fixed.

  12. It still flickers. Modern monitors have short persistence phosphors.

    60Hz used to be OK with old monitors - but we're talking 8-12 years old.

    TVs are only OK at 50Hz because the phosphor used in those tubes has quite long

  13. not true. it will be a loose solder joint. it is unrelated to adjacent
    speakers. about $40-60 would fix it.

  14. loss of width and E-W correction. possible a transistor has failed.
    are you in chch?

    i fix monitors.
    Alan Liefting, Nov 19, 2003
  15. that monitor should be able to work up to 1024x768

    Interesting. His explanation seemed plausable enough to me, and as it was
    such an old monitor I didn't bother arguing. Noted for future reference :)

    That was meant to be specialise.
    dickydoo, Nov 19, 2003
  20. Bruce Dix in Main Street (Bruces) and another outfit in Ftizherbert Ave
    also deal with monitors.

    They're somewhat closer than Shannon.
