Problem with Supergun and outputting Red on certain Sony tv's

I Bought a supergun recently and i'm having problem with the red output, i've been told that it's due to the chassis used for this model of TV that the red out is weak on AV1.

I was wondering if anybody else has a Supergun set up on this model of TV or any other TV, and if you've experienced similar problems?

This is what the output looks like at the moment, the camera has made it look slightly better than it is.

I've been told that fitting RGB will not remedy it, all my other retro consoles work fine thought.

 

Never heard of it before but it doesn't surprise me.

What supergun are you using?

 

I'm not sure if I understand what you're saying. Are you saying that the red output from your supergun has a weak signal? If that's the case, you could build a small amp for it. I know nothing about that, but someone else ought to be able to help you.
