T4i Autofocus Issue

[Wen]

Hello, 

I have an EOS Rebel T4i. The camera works when I use manual, but it won't take the picture when I switch it to auto. Switching the lens didn't help. Is there a way to fix this or do I need to buy a new camera?

You should try 2 things:

1. Switch to full auto (green square) and see if AF now works.

2. Check if this option is inadvertently set to 1.  If so set it to zero

Thank you for your help! It's working now.
