There's been a bit of talk of the A1080 monitors snapping and locking the A1000

My problem is similar but different. After warmup the A1080 starts tosnap and
the screen momentarily shrinks. It gets more and more frequent as the system is
on longer, until, after a couple of hours, it snaps and the display dies. The
computer is still working fine. I power cycle the monitor and it is fine until
the next snap. This got progressively worse (shorter warmup period before it
starts, and once the display started dying, power cycling only gave me 5 - 10
minutes before it died again).

My service man checked it out and thought that some voltages were too high and
perhaps a leak in the flyback transformer, but he hasn't been able to cure it.
A friend has an A1080 with his Amiga too, but our serviceman says that the 
two monitors are only the same cosmetically. the chassis are entirely different.

Since I'm doing mostly programming, I decided to get a cheap composite,
monochrome monitor. It works fine. The problem is entirely with the A1080.

Are schematics available for the A1080? CBM? Is there more than one design for
an A1080? Is there a non-messy (ie no chroma-dope) treatment?

                                Thanx,
                                   Terry
