Sounds to me like the refresh rate my be set too high and the monitor is
eating itself. But I would think that a recent monitor would just reject a
refresh rate that was set too high. All my Sony and Hitachi monitors just
refuse to run at a refresh rate that is not supported.
Both flyback transformers and caps will discolor when abused, this is visable
if you open the case. Caps are easy if they are not too burned, you can
order a new one through digikey, if you can read the specs.
In the case of a fried flyback I always just replaced the HV card in the
monitor. The flyback will often have a needle sized hole burned in the
casing. You can both smell and hear this , it smells like a thunderstorm
and sounds like a car with a pinhole leak somewhere in the catalytic
converter, much like pushing air through your teeth.
If you decide to swap the HV card on your own be careful to discharge the
tube before you try to disconnect it, two screwdrivers work well for this.
One the is inserted into the hole in the back of the tube and one that is
slid down the first and makes contact with the back of the tube, you will get
a nice blue arc about 1/4 inch long. Do that a couple of times before
attempting to disconnect the card from the tube, the connection will often
look like a suction cup with two prongs in it. If you don't do this it you
will probably not die but you will jump higher and faster than you ever have.
(50KV will do that) The couple of times I didn't fully discharge a tube
before trying to change out a HV card I lost the feeling in a couple of
fingers for a week or so, it burns a really neat hole in your finger as you
jump straight up nearly 3 feet. Interesting to say the least.
You are better off just tossing the old monitor and buying a new one.
