Please Help flash not in sync with camera

Hello, 

 

I'm a rookie yearbook teacher.  I bought 5 canon dslr rebel sl2 cameras at the same time. 

Four are working just fine.  

I sit at my desk and point all 5 at the same spot but one camera turns out dark photos.  I have tried resetting all camera settings, I have replaced the battery, and I have tried matching settings side by side with the other identical cameras but nothing works. 

The pre-flash goes off every time, the flash does not seem to go off every time, but either way the photos from this one camera always turn out dark.  If i turn the flash off the shutter stays open longer and the pictures turn out brighter but I need them to be able to use it at a night game for homecoming this weekend.  

 

PLEASE HELP

Has it worked before? It could be defective, call Canon.

It's worked for the past two years but now all of the sudden the photos are black.

If it is not in wireless master mode - and the SL2 might not even be capable of that - then it should be working. My advice still stands, call Canon, it is probably defective.

You "tried" but did you actually succeed? You need to be in M mode.  Did you have to reset the date/time?

I went into manual and did the clear all settings and the clear all format settings. Then I went line by line with other camera to make sure the settings matched.  All of the cameras worked the same until two days ago and I have no idea what changed but all of the sudden 1/5 has dark photos.

Well you pretty much answered your question.  I think it has problems that need the service center.

There are 2 possibilities that I see. As mentioned above, make sure the flash is not set to be a master for a wireless slave.

 

Also make sure that the flash firing is enabled instead of disabled. Disable will allow the flash to fire to act as a focus assist beam, but not during the shutter opening.

 

See pages 189-194 in the electronic version of the manual.
