[comp.sys.zenith.z100] Monitor dead on zenith 151

I have a zenith model 151 PC whose monitor recently died, or so I thought.
Let me describe the history of the problem:

The characters on the top lines of the monitor have become increasing skewed
to the right, breaking characters in the process. The characters below
these few top lines are fine. Also, when the monitor is on for a little while
the monitor goes blank.  I go back the next day and the monitor works, but 
the skew is worse and the monitor dies in less time. This process has
continued for a week or so and finally the monitor will not
work at all. So, I borrow a zenith monitor from my friend and plug it in. The
skew problem is worse than ever and the skew oscillates back and forth on
the screen, but the monitor does not go blank.

I still think that my monitor is dead as a doornail, but after plugging
in my freind's monitor I think it may be a video card problem also. Any ideas?
By the way, the monitor is monochrome.

Any suggestions where I can get inexpensive repair parts for this job?
Thanks for all help.
