Help! I was taking pics with my Kodak Easyshare z730 and it froze- optical zoom out - just shut off. I removed the battery thinking it needed to be charged- charged it completely and now it still doesn't work right. I turn it on- works for about 3 seconds- green light blinks 5 times and it shuts off again. Is there anything I can do to fix it? Any help is greatly appreciated.
