MegaPixel Display N4000A Question

[nickzinn]

I have a MegaPixel Display N4000A (manufactured 1991), that I have lightly used since I picked it up in 1999 (loading dock of Moore building at UPenn).   I recently started getting back into the NeXT scene and it has developed this white fringing outside of the display image.  This was only after a recent weekend of using the computer.  Oddly adjusting the brightness changes the white fringe but doesn't actually remove it, even when brightness is all the way down.  It doesn't seem like burn in, because it is outside of the display area.  Is this a sign of the dreaded NeXT monitor death or is there something I can do fix it?

Thanks in advance!

I forget and this might be 100% wrong, but there used to be like a voltage pan twisty thing to regulate positioning/overscan etc inside the monitor, and it may be a sign one of the caps might need to be replaced. We have more hardware experts here that will know the answer but that may be a lead on some research.

I have the adjustments documented here:

Could be caps, but try the dynamic focus.

Thank you guys so much!  Yes monitor just needed to be adjusted.  The cutoff and white levels had shifted over 35 years I guess.   Sort of easy to fix (needed to use mirror and plastic screw driver head).
