EOS 4000d black screen but camera shoots. help!

[rigelkitty]

Hi everyone,

I've just acquired an EOS 4000d from someone who used it only sparingly (allegedly). The first time, I was able to take a few shots, and everything looked ok; today, the LCD screen went black again and never came back. Right before that, I was trying to zoom in on a flower bud. I was unhappy with the automatic mode and switched to manual, and that's when the blackout happened.

Actually, when I switch between modes, the screen flashes for a moment with the usual text, but it goes black immediately.

The camera sounds like it autofocuses with each mode I select, and it appears to shoots photos and save them to the SD. I've tried a lot of things that I've read about:

-removed SD card and battery

-put a new battery in

-cleaned all contacts

-removed the rubber cup on the viewfinder (and it looks like this model has no proximity sensor anyway)

Does anyone have another idea? Is there some hard reset button hidden somewhere that would allow me at least to reset everything to factory defaults?

Thanks in advance!

If it is taking pictures you can still transfer them to your computer but USB. Try pushing the Disp button top left on the back. Remove any battery grip you may have on it or any other add-on. Try a different lens, too.

"-removed SD card and battery"    good try

"-put a new battery in"                    good try (make sure it is a Canon brand battery)

"-cleaned all contacts"                    won't help, almost never does

"-removed the rubber cup on the viewfinder"                ??????

Many "Rebel" series cameras have an eye proximity sensor which blanks out the rear LCD when you put your eye near the viewfinder. 

Sometimes the rubber eyecup can slide up slightly and block the sensor causing the rear LCD screen to be unusable.

I do not remember that. And, I had severaal XTi's.

So, why remove it?  Removing it blanks out the screen.  It needs to be put back in place and properly seated.

Hi,

"Try pushing the Disp button top left on the back." Yeah nothing happens, regardless of which buttons I push

"If it is taking pictures you can still transfer them to your computer but USB." I know, but I can't see what picture I'm taking without the LCD 😕

"Try a different lens, too." I don't have any 😕

Thanks for replying!

"Thanks for replying!"

You won't like this post so much. But I believe your Rebel is done. Because, any repair is going to be more costly than it is worth. 

A different lens is worth trying, though first.

Yes, I read on another thread that it should be removed to check for dirt and clean up, then put back in place. Anyway, the 4000d doesn't seem to have that sensor. Not that I can see. So, that couldn't be the problem.

Completely removing it has the same effect as properly seating it. It's only when it is slightly displaced and blocking the sensor (on cameras that have the sensor) that it is a problem.

Thanks.  I'm not sure if I ever had a camera with the sensor.  It sounds like a potential nuisance.
