Hi, I need some help diagnosing and solving a screen distortion problem on my WG U3000 monitor. There are distortions along the sides of the screen, and I am stumped as to what to do next to correct the problem.

I have recapped the monitor board using Bob Robert's kit, and I have replaced the B+ filter. Additionally, in an attempt to solve screen jitter, I replaced C115, Q205 and Q101.

Here's a video of what the display is doing with no input signal and the brightness turned way up to show the field.

Any input or suggestions are appreciated.

Thanks.
