And yet again it seems to be the ribbon cable... (time to find a new game gameboy)

It seems to be something with the front PCB (changed the back one and removed all mods), but my other front PCB's have a wornout ribbon cable it seems (on an image if I keep the front a certain way) and the other a distorted screen (I think because the part above the second screen screw is torn).

Did you insulate the inside of the RCA jacks? Maybe something inside is shorting the right channel when you close it.

Unlikely, because the headphone jack also has that problem and when I switchup the cables it also changes channel.

Well the soldering seems to be fine

If you lose signal when you finish assembling the game boy, but it comes back when the case isn't putting pressure on something, it means you have a bad connection somewhere in your pro sound jacks. If it's feasible, take them out and check your soldering.

That fixed it, but still have a distorted screen... (But with another front PCB that had the same problem, it worked like a charm). And after putting it together again I yet again lost the right channel (in jack and RCA). I really don't have any luck.

I do have a right channel, but only without the top 2 screws from the case

You didn't peel the polarizer layer.

I fixed it (replaced the front PCB), but now I somehow get a biverted the screen (without a biversion chip) and on one side is distorded. and also the screen is only really visible on the lowest contrast. (I might have been a bit wild with removing the film, because all the glue was still there)

Where did you solder on the RCA jacks? Did you switch there aswell? the center is signal and outer is ground on them

apparently I had wired left to ground and ground to left. So I fixed that, but now right doesn't work....

Okay, picture explained a lot.
You could try re soldering the connections/ uploading pics of wiring/ or rewiring from the volume pots to alternative points like such:

Rewiring to these points is not controlled by the volume knob though.

Edit: Just tried soldering to those points, with the same problem
