Don't do it!!!  I use to do convergence adjustments on TVs so I assumed that 
I would be qualified to do it on a computer monitor as well.  Well ... after
trying to converg two or three different monitors (including a NEC 4FG), I 
have come to the embarrassing conclusion that computer monitors are beyond my
skills.  

Because you are sitting so close to the tube when you look at a monitor, the
gun alignment is critical.  I believe that monitor manufacturers must 
invest a lot of money and time in developing equipment to aid in the convergence
and alignment procedure during the assembly process.  Mere mortals don't
stand a chance of duplicating their ability.

Furthermore, it is my opinion that local computer repair technicians don't
have the equipment or practice to do a decent job either.  If I were you, I
would continue to return the monitor until you get one you are satisfied with.
If you bought it locally, don't let the place you bought it from attempt to
mess with it.

There has been a lot of discussion in this news group about the poor quality
of the new NECs in terms of convergence and alignment.  I went through three
4FGs until I got one that was OK.  It is a real shame that NEC doesn't do a
better job of QA.
