Kramer's back
Have you voted in the AE-100 reliability poll?
AFAIK, colour uniformity is a problem with the AE-100. In my experience, ALL units suffer this problem to some extent - some more than others.
My second unit was far better than my first - acceptable but not perfect. The first unit was very bad - unacceptable.
ALL LCD PJs suffer from colour uniformity problems, but again, some are tolerable (not noticeable under normal viewing conditions), some just cr*p.
After 2 units I'd be looking for a refund & a newer model.
Best of luck with your retailer
