    Just a purely informational request.

    I've had this monitor forjust under 3 1/2 years (the warranty was for
    3 - damnit :p). I want to keep it - though I have already purchased
    an LCD to replace it, if temporarily.

    Anyway, the monitor still works well. The only complaint I have is
    that every so often, the focus of the screen suddenly goes out of
    whack. It is *not* less in the center and it does not seem to be a
    'shift' towards any direction.

    In the defect's infancy (for this monitor :)), after 5 minutes of
    this, there would be a slight pop and the focus would return to it's
    normal state (or so I think). The other way around this was (and
    still is) to shut the monitor off for almost any length of time - from
    a few seconds to a few minutes - andthe time left off didn't seem to
    affect the recurrence of the problem...

    .... except for the inevitability... time. The problem occurs at least
    once a day and sometimes rears its head after 10 minutes for several
    recurrences. It has also come to the pont that the popping doesn't
    happen anymore (admittedly I haven't fully tested this - but the
    popping always occurred within 5 minutes).

    I've read the very long FAQ located at
    http://www.repairfaq.org/sam/monfaq.htm#monrmcoc but it's well over my
    head.

    Since CRT's are a dying breed - does anyone have a clue what is wrong?
    This way I can see if repairing it is worthwhile (even if it's a few
    hundred!). The brightness is still very good (If there has been any
    degradation, I haven't noticed) and everything else performs as I
    remember: it's a very good mointor.

    I appreciate any feedback - whether positive or negative, chiding or
    kind.

    Thanks!

    Blooming. Look for that word and see whether your symptoms match.

    The high voltage multiplier may be defective. In most CRT monitors, this
    device is part of the flyback assembly. There are other support components
    that can cause some types of problems.

    The set should be properly checked by a tech who has the proper training and
    service experience.

    This is a defective CRT, I have one that does exactly the same thing and
    have messed with a couple others. Sony had a bad run of tubes, there's
    nothing you can do, however I find mine only acts up once in a blue moon,
    and a power cycle or two will usually "fix" it.

    Wow, thanks all! Good advice here. I found a good online shop that
    sells the same montiors so I may just order another backup CRT.

    As one of the posters have mentioned - the problem is very sporadic.
    As soon as I power down, it could rear its ugly head in a half an hour
    or two days.

    I guess it's just a fact of life (but strangely, every other monitor
    I've had has lasted for 7 years plus easily) that this just simply
    happens.

    Again, thanks for the advice all. Good reading. :)
