Does anyone repair NEC PM-1971A Monitors?

Show us how it was hooked up to the unit. If hooked up to the
VTR you may need to make an adapter to run it on a regular
TV set. Someone may pipe in on that. If it used the regular
2 or 3 cables to run it you need BNC to RCA adapters.

Screen burn in can only be fixed with another CRT. I would guess
an NEC 19" from the same era will use the same one.
In any case show us how it was hooked uo to the game with pixs.
We can take it from there. Remember the more info you give the easier
we can all help.
