Your camera LCD could be defective.
You need to contact Olympus Service.
Your camera should still be under warranty, so you should contact Olympus Service before the one year warranty expires.
Regarding Olympus stylus 1010: When looking in the viewfinder (the lcd screen) everything looks yellowish, but the picure I take looks pretty well color-balanced. This is on either the Auto or the other mode (the one that looks like an outline of a camera). I have
not adjusted the white balance. Is my camera defective?
