Hello,

a) My monitor has a greenish picture with retrace lines. I
disconnected the
cathode for green, result: no change. A measurement with a crt-meter
show's
no problems like hk-short, the emission from green is the same as red
and
blue. The focus of the picture is okay, turning the SC-pot (G1 ?) on
the
flyback changes the brightness.
When I switch off the monitor i can see green and purple spot in the
middle
of the screen.

The monitor is a Iiyama 17" Vision Master 404.


Thanks for your help.

First off it sounds like the tube is being overdiven. Have you tried
turning the screen voltage down to see if the retrace lines disappear?
Is the degaussing coil working?
