rainbow on hd75 not on hd70

[tomk246]

I opened my brand new hd75 last night, put on a bluray (diehard 4) and watched; watched a rainbow pattern everytime I moved my eyes.
My neighbour has a hd70 and I've watched loads of DVDs and played for hours and hours on it with a xbox360 - never noticing a rainbow - making me think I was immune.
Is there anything I can do? Or will I have to take back the pj? The screen is a 92" beamax matte White
Thanks,
Tom

Acording to what i read somewhere the 75 was supposed to have a better colour wheel than the 70 that was even less prone to rainbows

I had a demo on a 70 a few months ago and only saw the odd rainbow which prompted me to buy my first dlp pj (Planar 7010) which shows virtually no rainbows(thank goodness).

your eyes will adjust to it, it may also be effected by the way its setup.
