If it's a bypass cap or power supply filter, you should NOT see any signal

Other than checking for obvious shorts and opens, what's a good way to
check a (safely discharged) capacitor for such problems? I do have one monitor. I haven't tried to
power it up, but written on
the case is the word "DIM", presumably identifying a failure in the
monitor somewhere. I've never repaired monitors, so I'm not sure what
a dim image is suppose to indicate. Failing HV drive circuitry?
Power supply problems more likely than anything else. Maybe caused by
weak capacitors, as those will age more than any other part. Other
failure modes will all (mostly) cause an outright failure.
