I just posted about an issue with my 1D Mark IV, so I pulled out my 50D backup camera, which I have not used for at least 5 years. It has been sitting in a camera bag the entire time. When I charged up the batteries which were totally drained and tried to turn on the camera, I get nothing. There does not seem to be any power to the camera. I ordered new batteries and charged them up, but got the same results. Absolutely nothing, no power to the camera. I tried taking the battery grip off and using a single battery in, but have the same results.
Any suggestions, please help. I have a number of upcoming shoots in the next few weeks.
