First, make sure the CRT glasss is clean and not dirty along both
sides. (A little humor) Next, you need to degauss the CRT. Normally
this is done automatically at each cold-start turn-on. But, something
may have become magnetized that the internal degaussing can't overcome.
A regular degaussing coil is several hundred turns of 20 to 22 gauge
wire wound in a 12 - 18 inch diameter coil and connected to 130V AC
(assuming you are in the USA). You move the coil very slowly all
around the CRT face, sides and top and bottom and back of the housing.
Then you move slowly away at least 10 feet from the crt and then unplug
the power cord of the degaussing coil. The outlet into which the coil
is plugged should also be ten feet away. Do all this with the monitor
facing the samme direction it will be facing when in final use as the
earth's magnetic field can have an effect.
Noe, if you don't have a degaussing coil. you can try to borrow one
from someone who does, or you can try the following.
Use a small soldering gun as a degausser. It is not as powerful, but
sometimes works in a pinch. The only problem is that the tip gets
red-hot after a few seconds. So, do your degaussing with the tip of
the soldering gun placed in the middle of a wet rag to keep it cool.
Report back the results.
