EOS Rebel T7 Flashing green light and busy message. Stopped working…??

[Gream19]

I am a newbie to using this camera (Canon Rebel EOS T7). I ve used it for a couple hundred pictures and then I am unable to get the shutter to take a picture. In the view finder, I get a flashing green light with a number 9 next to it. I also get a busy message that flashes, the ISO is 3200 and have it set on the A+ on the dial… Like I said, its work the whole time until Bam…I am not sure if a setting got changed that I can’t figure out? Like I said - total newbie here!

Hi and welcome to the forum:

Have you got a spare card?  I suggest shutting down the camera, removing and replacing the card.  Turn it on format the card in the camera.  Then try to take a photo.  See if you get the same result.
I is possible you have inadvertently changed a setting.  In that case go to the menu and do a camera reset to factory defaults - the instructions to do so are at P194 in your manual. At this link 

Also, I strongly recommend you view the following tutorial:

If you are not familiar with DSLR cameras, you might first want to watch the following tutorial:

Also, make yourself familiar with your camera's manual, it is a wealth of information on how to use your camera specifically.

The OP has the Rebel T7 not the R7.

Is your memory card full? Try another empty card.

I have a T7 and, so far and knocking on wood, no problems that are caused by the camera. The operator is a different story. Let us know what you find. Also, download the manual, go through it with camera in hand and learn what the T7 can do.

Your descriptions are consistent with taking photo of subjects that are too close to the camera in a poorly lit environment, at least poorly lit for the camera to function.

It also sounds like you could be experiencing issues with your memory card!

Nope, I switched that out and I also changed batteries… didn’t change. Thx

Good thought - I will Thanks

Thanks Demetrius.  I did type in T7 in the search for the video, but obviously missed that it was actually offering the R7!

Hi again:  Sorry about the mixup of models for the video on the camera controls.  This is the most comprehensive tutorial I can find on the T7/T7i (almost identical):  You may find it helpful
