I have checked that all doors are latched and that no door sensor is stuck. I also cannot access the camera via USB as my computer does not "see" that anything is plugged in. Thus, I cannot try to install any new firmware.

Call Canon Service for a repair form.

My T4i is completely unresponsive. I have tried different cards, batteries and lenses. Ideas?
