Hi Pramit.

Please help if you can :o)


I will try my best to help you out.


First, please try removing the memory card/s and turning it up. Let me know if that changes anything.

I don't understand. Turning it up?


I mean turn it on. Once you have done that and it doesn't help, follow the steps below. If it works then do not try the steps below and let me know.


1. Remove the main battery.
2. Remove the Time/Date battery (the tiny Lithium battery). Click on the pic below to see how.
3. Turn the ON/OFF switch to ON allow the camera to sit idle for 10 minutes. Then turn it OFF.
4. Clean the battery contacts with alcohol and q-tip and get some sandpaper and rub the contacts on the battery. Clean the small battery too. Also, clean the battery compartment with alcohol and q-tip. make sure there are no bent pins or any dust particle.
5. Insert both the batteries(Main battery as well as the small time/date battery). DO NOT insert the memory card. Turn the camera ON.

Let me know if it helps.

If it doesn't then the problem is internal and probably any of the circuit board will require replacement.
For that you can either send it to Canon.

If all fails, then you can try for repair. Also, you may try search for "Camera Repair" and provide your area details so that you can locate local shops.


If you have any queries, please do not hesitate to ask.
