I have a Canon Eos Rebel T7I and i have two lens a 55mm and 300mm, when I switch them between the two I always turn the camera off and then change my lens. Well when I changed my lens to the 300mm and turned my camera back on my digital screen would not turn on so I couldnt use my touch screen to change my camera settings. However I can look through the eye piece and still take pictures but if I wanted it to playback and see the image it would not show me. Any suggestions I just bought this camera and both lens maybe 2months ago.

skylaird93,
There are a few troubleshooting steps I'd like to help resolve this issue. We'll reset the camera, which should restore it to a default state. These steps should clear out the memory and thereby any errors which may be present.
- Anything attached or installed in the camera — memory cards, the lens, the battery, battery grips should all be removed.
- Once the lens is off let's check it using the steps below.
a) Clean the lens contacts* to restore connection with the body.
b) Try using a different memory card. All memory cards should be properly formatted in your camera prior to use.
*Warning - Do not clean lens contacts on either a Canon lens or the camera body with an eraser! It's easy to rub off the gold plating on these contacts and end up with data communication problems! Our strong recommendation is to use a soft, clean, micro fiber cloth. Please do not use anything abrasive.
c) Try using a different Canon EF series lens. It doesn't have to be the same focal length as the one you were using.
d) If you are using a third party lens, we recommend discontinuing its use. There can sometimes be communication error related issues with third-party lenses. Ensuring that you're using a Canon lens eliminates that as a potential factor in the error.
If the issues seem to persist the next step would be to send the equipment to Canon for service. You can set up service through the Canon web site at www.usa.canon.com/repair
