I have a 50d its only about 2 months old, i have not had any problems with it at all untill now. the last time I used it it worked fine , loaded pics on computer and put it away in my camera bag. Now, i pull it out today to use it and it wont turn on Ive tried everything checked lens connections, batteries , took out the clock battery, made sure cf was in right and door closed. Im going nuts here and the closest best buy is 3 hrs from my house. Please tell me im missing something and its something simple, any ideas would be greatly appreciated.
