This sounds as if the EHT is arcing somewhere.  If you take the monitor
apart, inspect the lead which goes to the side of the tube for any signs
of tracking.  This will show up as a black line, pay particular
attention to the round insulating cap at the tube end of the lead.

Be _very_ careful, the voltage in this region is several tens of
kilovolts and it holds charge almost forever so you _will_ get bitten if
you don't know what you are doing and it can be fatal.
