if u unplug the monitor for an hour or so, so it's totally cold, then turn it on, you should hear that common boing/crunch sound you hear with tv's/monitors as the degauss circuit kicks in during cold power up.
if u cant hear that, the degauss circuit is faulty
in which case theres a good chance the degauss posistor (a.k.a positive temperature coefficient thermistor, or 'PTC') itself is faulty
often they will look like as seen in the pictures below....
u'd need to replace that part (often you will find the degauss posistor close to where the degauss coil (which surrounds your monitor tube) plugs into the main board.....), or, modify the circuit so that it bypasses the posistor altogether and allows for manual degaussing via. eg. a pushbutton (see here:
http://www.ukvac.com/forum/plz-help-me-add-manual-degauss-button-to-circuit_topic328792.html) .. or other option, buy a manual degauss wand as mentioned in the post above. you get cheap chinese ones, or more expensive ones.. im not personally recommending the chinese cheap ones though.. just saying they are out there ...
