My Canon Rebel T1I won't power up. It may have started when

Customer Question

My Canon Rebel T1I won't power up. It may have started when I bumped it lightly on a doorway. I've fiddled a lot and nothing happens. Is there an easy fix of some kind?
Thanks,
Scott

Hello and thank you for your question, I would be happy to help you today. Have you checked the SD card hatch to make sure it is latched tight?
Customer: replied 2 years ago.
Yes, it is latched tightly and so is the battery compartment.
Customer: replied 2 years ago.
I'm a very good do it yourselfer and am willing to open the camera up if needed.
Expert:  Dan replied 2 years ago.
Try pressing the display button to see if anything comes up on the screen.
Customer: replied 2 years ago.
Nothing comes up on the screen. There does not seem to be power to anything. I have measured the battery voltage and it's fine. As I mentioned this started when I bumped the unit against a doorway. I think something got knocked loose.
Expert:  Dan replied 2 years ago.
Possible, but there is not really much that would be lose inside that would disconnect. Try removing the battery and thoroughly clean the metal contacts. You can use a cotton swab moistened with alcohol. Rub vigorously and make sure they are completely dry before inserting it back into the camera.
Customer: replied 2 years ago.
Will do but will have to be a bit later. Could the matter compartment switch be faulty? Or the one on the SD card compartment?
Expert:  Dan replied 2 years ago.
Definitely. I was going to have you check them next to make sure both micro switches are intact.
Customer: replied 2 years ago.
How do I do this?
Expert:  Dan replied 2 years ago.
Check both the battery and media covers. Look carefully for a small switch under both covers.
Customer: replied 2 years ago.
I see the switches. They seem to move just fine. How can I test them electrically?
Expert:  Dan replied 2 years ago.
As long as they are intact and appear to move freely, they are probably good. Try using a tooth pick and make sure the spring back up when you push them down.
Expert:  Dan replied 2 years ago.
Did you try cleaning the battery yet?
Customer: replied 2 years ago.
Cleaned the contacts. Didn't help.
Expert:  Dan replied 2 years ago.
When you bumped the camera, how hard and where approximately on the body did the impact occur?
Customer: replied 2 years ago.
It was not very hard and I don't know where it hit. There is no mark on the exterior. I'm not totally convince that this caused the problem. Could very cold temperature cause this kind of problem? I was in Antarctica when it happened.
Expert:  Dan replied 2 years ago.
Very possible as that would make the circuit boards more brittle if the camera was extremely cold. One more thing to try would be to check closely around where the lens attaches to the camera to make sure the contacts don't appear to be damaged.
Customer: replied 2 years ago.
The contacts are fine assuming they are the spring loaded pins along the bottom of the lens opening.
The camera was not super cold because I wasn't outside very long.
Expert:  Dan replied 2 years ago.
The only other thing I can think of would possibly be the flash control circuit. That would be something that would need to be sent in to be repaired.
Customer: replied 2 years ago.
Is that circuit susceptible to damage from cold or shock? And if it is faulty the whole camera goes dead?
Expert:  Dan replied 2 years ago.
Any component can be damaged by cold or shock. My concern is it doesn't sound like either was severe enough have caused this. The flash circuit can keep the camera from turning on if it is faulty, and that could have just failed coincidental to your incident. You can have the camera evaluated at several repair shops at no charge if you would like to have one of them check it out?
Customer: replied 2 years ago.
If there's nothing more to try then I guess we are done. And, I'll go have it checked out.
Expert:  Dan replied 2 years ago.
My apologies, but we have pretty much exhausted anything you can try. Do you have a local camera shop, or would you like me to recommend one?
Customer: replied 2 years ago.
I have a local one but he could not get to it in time for my travels that start tomorrow. Thanks.
Expert:  Dan replied 2 years ago.
Very good. Good luck and check out this link if your local shop doesn't work out for you.
