Hi,


While something mangetic in the vicinity is the most likely cause as
suggested in another posting, note that monitors are adjusted assumgint
they will be used in the normal orientation. When tilted as far as
you have it, the Earth's magnetic field direction is significantly
different than normal.


I'm pretty sure it isn't something magnetic because I had a different
monitor in it that didn't have this issue.

What do you guys think about my theory that the built in degauss coil is
actually messing it back up slightly? I haven't proven it yet, but the
manual degauss coil seems to make it look pretty good and then when I turn
the monitor back on the internal coil seems to mess it up a little more. I
haven't tried rotating it 180 degrees to see if it works better in that
orientation yet, I might give that a shot too. Any other ideas?

Thanks,

Alan

Hi Alan...

If you mentioned the age of the setup I musta missed it...
but is it possible that the monitor is old enough that it
requires purity setup?

Us really old guys will recall the days when the yoke wasn't
cemented to the tube... used to loosen a setscrew, slide the
yoke back on the neck of the tube. Find a red blob, center it
with centering magnets, "purify" it with yet another magnet,
then slide the yoke back as close to the bell as you could
without upsetting purity.

All behind the set, while holding a mirror in one hand around
the front so you could see what was happening. And hoping not
to grab the yoke itself And then came convergence...

Ahhh, the good old days
