I am trying to repair a vertical size and liniarity problem with a Viewsonic
E771. The picture only fills about 75% of the screen and is non linear. It
is squishes and bows a bit toward the top of the picture. I have searched
and searched in the vertical deflection
circuits but have been unable to find a problem. I tested a lot of
components and even replaced a few, but no luck. I do have a schematic. I
can stretch it using the OSD controls, but that only fills about 75% of the
screen.

I'm know I'm not the first person to try to fix a problem like this. I find
other reports on the internet of this same model with the same problem.
But, I can't find and reports of what was done to fix it. Has anyone seen
this before? Or can someone give me some more direction?

Thanks.



To your question about has any else seen this problem befo The
answer is "Yes!" I like you, had tried everything I could think of
since this was the ONLY problem with the monitor. After more hours than
I wish to admit to, I tore the monitor apart for parts so that I would
stop going back to it with another idea. It became almost an obsession.
I shall watch this thread to see if you find the problem. Good luck.
