Thank you for contacting Canon product support. We are sorry to hear the flash on your EOS rebel T3 will not fire.
As a first step towards resolving this issue, we recommend you restore the camera's default settings, Mr. Stivers.
You can reset to the factory settings by following the procedure below. This will erase all custom settings on the camera.
1. Please remove the lens, battery, and memory card.
2. Please clean the battery contacts with a clean pencil eraser (be sure to remove all debris).
3. Please place the memory card and fully charged battery in the camera.
4. Replace the lens.
5. Power the camera to P mode.
6. Press MENU.
7. Go to the SETUP 3 tab.
8. Select CLEAR SETTINGS.
9. Press the SET button.
10. Select CLEAR ALL CAMERA SETTINGS.
11. Press the SET button.
12. Select OK.
13. Press the SET button.
Please test your flash by changing your camera to Creative Zone (P, Tv, Av, M, or A-DEP). Next, press the flash button. If you take a picture and the flash still does not fire, unfortunately, your camera will need to be sent to the service center to be examined.
For factory service, please forward your camera to one of the Factory Service Centers shown below. When shipping your camera, please be sure to remove the memory card and batteries. You are not required to send any accessories or manuals when shipping the camera. Be sure to include your name, street address (no P.O. boxes, please), telephone number, and a letter describing the issue with the product. If it has been less than one year since the camera was purchased, we ask that you also include proof of warranty in the form of a copy of your sales receipt.
As we do not provide RMA numbers for service, we suggest using a trackable and insurable service (i.e. UPS, Federal Express, Priority Mail) to ship your camera. Please package the camera very securely in a sturdy shipping box to prevent damage during shipment.
Please send your camera to one of the Factory Service Centers below:
Canon Factory Service Center
12022 Canon Boulevard
Newport News, VA 23606
Or
Canon Factory Service Center
100 Ridge Road
Jamesburg, NJ 08831
Or
Canon Factory Service Center
15955 Alton Parkway
Irvine, CA 92618
Upon arrival at the Factory Service Center, your camera will be logged in to our repair database and assigned a repair number. Next, the camera will be visually inspected and you will be advised of the findings. If the required repairs are covered by the warranty, the repairs will begin immediately, and you will not be contacted. When the repairs are complete, the camera will be shipped back to you via Federal Express. The length of time for the repair will be dependent upon the nature of the repair and availability of parts, if needed. Usually, warranted repairs are completed within approximately seven to ten business days of the camera's arrival at the Factory Service Center.
All decisions regarding warranty coverage are made by the Factory Service Center at the time of repair. If the repair entails something that is not covered in warranty, a written estimate will be sent to you at the address that you have provided. The repairs to your camera will not begin until you approve this estimate and make payment arrangements. If, after receiving the estimate, you do not wish to have the camera repaired, please inform the Factory Service Center of your decision as soon as possible. If you decline the estimate, the camera will be shipped back to you unrepaired.
Once you have confirmed with your shipper that the camera has been delivered, you are more than welcome to contact us for repair updates. Please include your name, address, and telephone number, as well as the serial number of the camera, in all repair status inquiries.
Please note that our U.S. Factory Service Centers are unable to accept packages from or return equipment to addresses outside the United States.
Please let us know if we can be of any further assistance with your EOS Rebel T3.
Thank you for choosing Canon.
Sincerely,
Robert
