Maybe... If you apply the HV to the mains connector, I suspect the only
thing that would fail would be the fuse (the 5151 has a linear PSU with a
nice fat mains transformer at the input).
If you apply it to the signal cable, well, it'll probably take out the
input buffer chip (a '04 IIRC, I can't be bothered to go and get the
schematics). Maybe some smoke. I doubt you'd get many interesting effects
In any case, the monitor is not unchanged at the end, so I would class
that as a modification :-)
