Sigma AV7000 supergun only showing green

I moved my AV7000 supergun to a different shelf on my bookshelf, and when I plugged it in now it only shows green (well there's some blue too, but definitely no red). :wtf:

I tried three PCBs and it's the same for all of them, so it can't be a problem with the PCBs (thank goodness).

I thought it might be a bad RGB cable, so I hooked it up to my TV in the lounge with the composite cable and it's still green. So it has to be either the supergun or the jamma harness. I looked inside the supergun but couldn't see anything loose or damaged. The Jamma harness doesn't have any loose or damaged wires either, but could a bad solder joint cause this? Everything else works fine (inputs, power, sound).

This AV7000 was purchased new from Tops in March 2018, so it's not that old. It's the newer version without the Color Brightness Control (CBC) knob on the top. Actually I wish I had that knob, maybe turning that would fix it...

Any ideas?

Here's the color test screen from one of my games:
