Tech: WGK7000 Vertical shrink

Hi all,

Tonight a buddy and I finished rebuilding a WGk7000 chassis. It has a new
flyback, HOT, cap kit and even the little tantalum cap that all comes with
Bob's kit. The monitor is now back to life but it has a vertical display
issue. The flyback was replaced because the old one burned out and even
damaged a trace in the process which was repaired. My theory is that it
might have taken out some other part with it that is now causing my display
issue. Here's a picture of what I have.

Thanks in advance.

Yeah we tried the card from the other side (which was working) and
there was no change in the status of the picture...

Yep. It's got to be something on the chassis.

Replace IC3 (vertical output) and IC2. This should fix it.

Did you check the components on the burnt trace? Sounds like something
pulled excessive current through the trace. It may be that a component
shorted and caused the flyback to die. That could be the source of your
continuing problem. At least that's my 2 cents worth.

Yeah we're talking about the remote cards that you can adjust the
monitor with without having to actually get near the monitor. Swapping
those had no influence on the right side monitor so I assume it's
something on the chassis.
