MS9-29 green bleeding

[gamezer0]

This is from an MS9 that I picked up recently. It got its flyback replaced (due to a focus issue) and I recently noticed that the green bleeds if I turn it up on the remote. This video was recorded with the remote pot at max value, but even at a normal value there is a bit of bleeding. No bleeding at all on the R and B channels. Is this normal and can be fixed with more tweaking of pots, or is there an actual issue?

There's zener diodes on the neck board that can break down and start leaking current. Try swapping them between the color circuits to see if it makes a difference.

30x is red, 31x is green, 32x is blue.

As I'm not great at electronics and the chassis repair is still under warranty, I'd prefer to not solder/desolder stuff for now, but thanks a lot for the suggestion!

Last night I tried adjusting the G pot on the chassis. It was too low, so turning it up and then the G on remote board down, doesn't display the issue (and the colors look amazing). I'll keep an eye on it, and test the tube with another MS9 I have; otherwise I'll send back for repair.

Thanks again.
