Monitor problems

["Frank Townsend" <ftownsen@iamdigex.net>]

I've had a setback in my Apple II and other computer endeavors:  my
venerable NEC 6FGP monitor is on the fritz.  The way this relates to Apple
II is that this monitor has both D-sub and BNC connectors and a switch so
that I can use it with my PC and Mac LCIII/Apple IIe card set up.

The screen image is squashed in the vertical dimension to about 25% of the
usual screen size.

Repair costs are fairly prohibitive since NEC charges ~$360 flat rate not
including shipping, and most local places won't look at them.

Does this sound like anything I might fix myself?  I am fairly adept with
soldering, checking components etc. and can deal with discharging the high
CRT voltages before beginning work.

Help would be appreciated!
