Hello,
My old (1994 mfg) 21" DEC digital monitor was screaming/whistling when i
went to log on this morning not loud but annoying high pitch about
frquency/pitch ? of whistling through teeth. there were *no* power indicator
lights (eg. amber for low power sleep mode and green for active ). i turned
it off few minutes turned it on and same whistle immediately with no flash
flicker from screen or power lights. of course immediatelt turned it off
my first guess is some internal switching power supply problem maybe ( just
from symptoms) ???
Any ideas about what i could do to repair ? *OR*
should i seek professional help because i might kill myself trying to
repair this ? *OR*
should i just toss it ?
thanks for any help to my (1) primery concern prevent killing myself and
to my (2) secondary concern repair

Unless you have sucessfully repaired a device with a switch mode power
supply and a hi volt supply capable of 30kv, stay out of it.

Hi, Rob. Your reluctance to dig into this is telling you something
(Examine your feelings, Luke). Very high voltage, potentially lethal.
You got 12 good years out of your monitor. Time for an upgrade.
Unless you're experienced with high voltage repairs, just toss it.
Good luck
