Report "I've had a pentax K110 for 4 years now. everything has worked great until recently. when I put freshly charged batteries in (no matter what brand) the camera will work for about 20 shots and than 1-the sutter clicks once as if trying to take the picture but does not want to re-open. it will only re-open if i turn the power off. also if i try to use the flash it will show that i have no battery power. but when i turn it on and off again the battery will show full. I need your help. Karl"
