Thanks for the input.  At first I thought maybe it got caught looking into the sun but even on cloudy days it was washed out. It's about 4 years old.  I have tried looking the problem up on the net and have seen in several places that many trail cams start doing that after 4 or 5 years.  Not that big a deal to replace it but I just wanted to find out if I was missing something before I did.
