Thank you (and everyone else) for your advice. I indeed think it has
something to do with a bad capacitor or transistor... Alas, without a
schematic, it's like searching with blindfolded eyes.

I don't know if it's the same beast, but a service manual with
circuits for an NEC Multisync 3D (model JC-1404) is available for free
download (in four parts) from he

If your monitor has an LA7835 vertical output chip, then change the
capacitors nearby.
