We have a 2205 with geometry problems on the crt. It has fairly
severe trapezoiding ,the spacing at the top is narrower than that at
the bottom, appx .4div narrow at top, .2 div wide at bottom. Any idea
what caused this? We tried degaussing the screen, absolutely no
effect. I inspected the tube for visible damage inside, nothing
sticks out as obvious. The horizontal deflection is fine, the trace
is inline with the graticules across the screen within less than .
1div. Any ideas how to fix this?
Thanks,
Steve
