    CRT monitor failing - health risk?

    Hi all,
    I have a 19" CRT Sony Trinitron Multiscan E400 monitor. It has been
    working fine until the last few days, but now all of a sudden the
    screens brightness seems to be altering by itself (eg dimmer, then
    lighter) of its own accord. It happens very rarely - maybe once every
    few hours. On one occasion the screen started resizing itself aswell.

    I would like to continue using it until it eventually dies, but when
    googling the problem I came across a poster that seems to have a
    similar problem here:-
    http://groups.google.com/group/sci.electronics.repair/browse_thread/t...
    and this post has me worried:-

    "This ain't what you asked, but I'd be concerned...
    The death of the monitor is NOT your primary concern.
    CRT monitors are run at about the maximum voltage you can get away
    with
    without generating excessive X-rays.
    If your voltage is normal but dropping as you increase brightness, no
    problem. But what if it's unregulated and going HIGHER when you turn
    down the brightness??? That's what happens when the bleeder resistor
    goes open.
    Can't tell from your description. But how much risk do you want to
    take with your eyesight?
    Where'd I put my flameproof suit??? OK, let me have it...
    mike"

    Now all I really want to know if should I be worried? Could the
    monitor be emitting x-rays? Or am I safe to continue using it? Is there any part that could fail in a CRT which could make it pose a health risk?
    Thanks in advance

    As far as I know the only "radiation" that comes out the front of a CRT is Electro Magnetic and only tiny amounts, which aren't enough to cause any harm.
    I doubt your faulty screen will cause you any health risks like that, your screen is more likely to be an electrical hazard.
