I know some people still prefer old CRT monitors over more modern LCD monitors even today. Unfortunately Cathode Ray Tubes or CRTs aren't serviceable since they are a factory vacuum sealed unit and this probably why no-one has replied. The black dot is probably a burn mark on the inside of the CRT if it's always there. When there's a problem with the CRT itself there's nothing one can do except replace the unit and it's not worth changing the tube as it will cost much more than the monitor is worth and anyway I'd be very surprised if they even bother making these old parts any more. One can buy 17" CRT monitors as cheap as 10 pounds and larger CRT monitors for a bit more at recycling businesses like Speedie Computers near Birmingham in the UK, so if you you still want to use an old CRT monitor, replacing the whole unit is certainly the best option. There's currently still an excess of old CRT monitors that need recycling after being replaced by newer LCD monitors and recycling companies like Speedie often have literally pallet loads piled up high and they'll be only too glad to let you take one or more off their hands for next to nothing. It's better if you can find somewhere local to yourself rather than purchasing online if at all possible or you'll probably end up paying more in postage than the cost of a replacement used CRT monitor because they're fragile, heavy and bulky to transport.
What kind of monitor, a CRT or LCD type?
What kind of parts are you looking for?
The CRT type has dangerous voltages inside the unit and unless you know what you are doing, I would not suggest you go poking around inside a CRT monitor.
you will need to update a new driver for the monitor
if it's too old you will need a new video card thats compatible with the new monitor.Which i think your brtter off doing.
please don't forget to rate me
we use the old CRT monitor made by motorola with TTL video signal and different
vertical &horizontal frequency signals than monitor with vga signal.at now we can not replace crt with lcd .is
there any interface to convert this crt signal to vga monitor signal for replacing the crt with lcd or vga monitor ,beacause this crt
is discontinued and the quality of video is weak.if you needs the crt specification i will post it for you.thanks.
Try setting the refresh rate to 60 Hz. (Maybe 75).
Is it xp?
Right click an empty part of the screen, properties, under monitor (I think; I'm on Vista) you can choose the refresh rate.
Most LCD's should be at 60 Hz.
