Hi guys,
so I just got my hands on another MS9-29 chassis. After 4-5 minutes warming up, it exhibits some issues on the green signal where green is flickering or what it looks like bleeding green.
I have no problems with the red and blue signal. See the link the to video. The following were performed but still exhibiting the same problems.

1.) Suspected faulty transistor on the green signal from the neckboard. Swapped green(2SC4001) with blue.
Result: No change, still showing same symptoms.
2.) Recap the whole chassis.
Result: No change, still showing same symptoms
However, green does not show over bright. Possible cause due to wrong capacitors on the board initially
I have ordered the RGB amplifier chip M51387P aka U201 chip and waiting for it to arrive, as that is my next suspected defective component.
In the meantime, I would like to know if any community members came across the same issue and what was your fix? If not, what would you suggest for this repair.
Thanks in advance!
