I believe the CRT is set to a 75Hz refresh rate. If the local power frequency is 50Hz (quite common in Europe), then setting the CRT to 85Hz (or, if you can't manage that, 72Hz) may help; 75Hz and 50Hz are likely to have some strobe effects.
Other things to try; turning off the lights in the room for a while - if the problem goes away, you know it's not a problem with the monitor. If the problem persists, try putting a power conditioner (ideally, a UPS) on the monitor power.
