The problem you describe is consistant with low B+ going to the flyback
transformer which results in low brightness level, poor focus, and blooming
when the brightness and/or screen level is turned up. More than likely if this
monitor has been sitting around for awhile, the filter capacitors have gone to
mush. Sometimes they can be revived by leaving the monitor on for a long period
of time <over 24hrs> but, usually, they require replacement.
