Have you tried viewing the picture on your tv??
Try checking to see if there are digital effects turned on, like sephia, mosiac, etc. Maybe that is causing it. See if you can find an option in the menu to reset camera to factory settings. Hope that helps.
I have a Samsung SCD86 and I got it off of ebay sold as is (yes I've been told that that was a bad idea!) It came with everything but just not the original box. Now, the picture is very dark and fuzzy, I can't see really anything. even in the viewfinder it is extremely fuzzy and I've cleaned the heads. The screen is really dark and you I can only see outlines if it's pointed at the light and the front door. Is there any way to fix it?
