Oh well today was my first day with issues with this body, I was shooting in video mode and switched to camera mode and nothing would happen, pressing buttons, nothing, the only screen that was on was the lower one showing your memory card (if you have it set like that) pulled the battery, worked fine.....until it went into sleep mode after 1 minute. Pressed the shutter button and same again, only the small screen was showing and none of the buttons would do anything, pulled the battery and it was fine. Sleep mode again camera would not operate. Same issue all the time, turning the camera off will turn it off but once you turn it on again nothing works.
Im gonna be contacting Canon in the morning and taking it from there, got a wedding in 8 weeks so I should be ok by then.
