LCD screen has gone blank

[RLaCount]

I received the Rebel t4i for Christmas. It's been working great until today. The lcd screen no longer shows any information. If I press any of the setting buttons (ISO, etc), nothing shows up. It worked fine this past weekend.

Thank you, ScottyP!!! This issue happened to me over the summer, (and just fixed itself) and then again tonight. Didn't even know about the eyecup thing. Thought I was going to have to send it in for repair.

Good! It is always great when there is a painless solution to something that seemed like it was going to be a pain.

I just had the same problem happen to me today. The viewfinder had somehow been pushed up. So this comment was EXTREMELY helpful.

My rebel T3i screen has gone permanently dark.  I do not find a proximity sensor around the view finder on the T3i and no mention in the manual.  No point asking about settings because the screen is dark and settings are not visible.  Help, please?

My rebel T3i LCD screen has gone black, too.  Nothing so far suggested has cured.  The instructions for the T3i do not mention a proximity detector above the eyepiece or anywhere else, and I do not find one on the camera.  I seem to recall there were LCD indicators in the view-through view finder, but that is dark now too, except for the red focus spots when they activate.  What do you think -- is it toast?

[ScottyP]

There is a sensor there. It is how the camera turns the LCD display off when you put it to your face and then turns it on again. It senses your face is close. Look in the index, not the table of contents, of the full manual, not the quick reference booklet. You can download it pretty easy and free from the Canon site too.

Pull the eye up up and off. Wipe the whole area with a clean cloth to be sure dirt or makeup isn't blocking the sensor. Put the eye up back on, making sure the rubber cup itself didn't slide up and block the sensor.

OK, I have here the 323 page instruction manual.   http://gdlp01.c-wss.com/gds/0/0300004720/02/eosrt3i-eos600d-im2-c-en.pdf#page=319  The index has 10 entries under D, but nothing that looks like "display off sensor."  I have removed the rubber and plastic outer viewfinder fitting from the camera, but can find no such sensor.  The plastic above the view window is solid and without features.  Here is a drawing of the sensor but it does not look like my camera: http://www.manualslib.com/manual/454362/Canon-Eos-Rebel-Sl1-18-55mm-Is-Stm-Kit.html?page=15#manual  

Is it possible there was an earlier version of the T3i that did not have this sensor?

Number 2 was my issue.  it's fixed now. Thank you!

I had the same problem yesterday and the ScottyP suggestion solved it immediatily. Just an additional point, the eyecup padding was just slid 1/16. Thank you for help!

"(2.) Also make sure that the rubber "eyecup" padding has not slid up 1/4 inch and covered the "display off sensor" that turns the display off when you put your face up to the camera."
