I've owned this Trinity since day 1 and this is my first problem i'm having. When I'm in sequence mode and i'm on a track and have a patch picked out and I start recording, as I'm playing the patch will change randomly on it's own. It also happens when I have a bank of sounds open and the safety pin is locked so I can run through the different patches to see what I want to use - it will also change randomly as I'm playing them. Has anyone had this issue before?

Is it changing to any random number or just one up or down?

It's changing to any random patch number. It seems to be changing only when i begin to play on the keys after about 15 seconds into it. if I just leave it alone and not play it won't change patches.

I think that you have problems with the Value slider. I had the same and I changed the slider. Now I don't have such problems.

This would be my first guess, too. Try to clean it with compressed air and some special electronics contact cleaner - or have the complete fader replaced. Might not be trivial, as you'll have to acquire the exact same type of fader. Probably the vibration caused by your playing causes this. You can try gently tapping the case near the fader to ensure that it is indeed a mechanical type of problem, not directly related to keyboard electronics.
