Sensor Issue?

I've navigated the forums here for a while (a year or so), but never really posted any questions. Now I'm in need of some input, and I hope you all can help me.

I have owned my Pentax k-r for almost a year now. I bought it brand new as a replacement for my k-m. For the past month or so, only when I turn it on after it's been off for a day or so, the first 5-10 images I shoot are either black or very dark, and the internal light meter reads everything as dark as well. It does clear up and register the correct light after I fire a few shots, but I'd really like to know whether or not this issue would be an easy fix or if I need to start searching for a replacement.

Any input is appreciated!!! Thanks

If you get this kind of behavior consistently, something may be wrong with the camera.

Are you use that it's not because of the way you've set up the meter (i.e. spot vs matrix), or due to changes in ambient lighting?

Would be great if you could post a few problematic photos.

Also, a few checks to do:
1. Different lenses
2. Different metering modes
3. Different modes
4. How does it behave with different shutter speeds?
5. Have you tried factory reset?

Right now it could be shutter, light metering, sensor...

... but in any event, I would check the purchase date so that you can make arrangements to send it back for repair if you still have a valid warranty.

My first thought as well.
