Hello everyone, I own the monitor MTC-9000 and the image is this, it seems that there is a red color, I proceeded to replace all the electrolytic capacitors and the 3 transistors on the neckboard, but without any result, what can I do?

does it have a pot or 3 switches for contrast?
if you ground the red gun do you see red on screen, if you swap red and blue on the input connector does the signal appear for both?

grantspain:

I have the exact same problem. Its not the tube and transistors and pots on the neck are just fine. Any help is welcomed.
