My cannon EOS 7D is not turning
My cannon EOS 7D is not turning on despite using a fully charged battery. Instead an empty signal of battery flashes at the top LCD (where f/nos, s/speed and ISO are displayed). The camera is 1.5 years old. I purchased 3 batteries as someone suggested me it as a battery problem. But none of them could turn on my camera. The empty signal flashes even the power switch is not ON i.e. in OFF position also. Please help.
