Discoloured Edge (possible source/lens misalignment?)

Been using the PPM for about a week now and am absolutely loving it! Played my first dark scene and noticed about 6-8" vertical band on the right hand side of the screen that is noticably a different colour/tone to the rest of the screen.

I originally thought it was because of reflections from the environment however the band moves with the projector.

I decided to have a look at it and I can see a grey edge inside/behind the lens on the same side (PPM right hand side). i think this is what is causling the band of discolouration…
