My canon eos1200D was working ok till suddenly it stopped showing display. People suggested to take off the SD CARD and BATTERY for some time. This was done. Now any activity on my part, be it plugging in the lens, or changing the setting the flash opens up and starts click click click ... and then stops. My next any move will start this clicking again. It is not flashing, but just the flash release hook goes back and forth. I can push this hook forward and stop clicking. But it would start again. Please help. What is this new problem? For any setting of the round knob this is happening. Can I ever have my normal camera back?
