What does a blinking top LCD panel indicate on my 5D3?

Often times when shooting numerous exposures with my 5D3, the top LCD panel begins to blink and I can't take additional images unless I turn off the camera and begin anew.  I had the same issue with other Canon cameras.  Does anyone have an idea as to why this occurs?  I do not believe that it has anything to do with a filled buffer, because waiting does not remedy the problem.  Ideas?  Thanks.

Re: What does a blinking top LCD panel indicate on my 5D3?

Which other models ? I've not heard of this before. Are you using something which you've used with the others when the issues occurred, memory cards, batteries etc. If you are, it's possible these are causing the problems. I'd probably clean the battery contacts or even take out the small backup battery and put another one in or just clean the contacts for that too. Batteries can cause so many problems with electronics. My digital vernier calipers threw a tantrum one day, I put a fresh battery in and hey, they work just fine again.

Did you install Magic Lantern?

Re: What does a blinking top LCD panel indicate on my 5D3?

Does the whole top LCD blink steadily, but otherwise shows a normal display (ie no flat battery, exposure exceeded indicator, err70 or anything "expected")? I'm not aware of any feature that behaves as you describe. It sounds more like a fault of some sort, albeit an unusual one. Perhaps you could post a video of the problem though since it's not clear what you're seeing exactly.

Another poster mentioned Magic Lantern. While ML can crash sometimes and cause eg err70 errors which require a camera reboot, it doesn't have any direct control over the top LCD so isn't able to deliberately flash it in the way that you describe.

To all:

I do no have Magic Langern installed.  When I shoot multiple images in a row, at time the camera appears to lock up and the top LCD blinks forever.  I have to turn off the camera and wait a second and turn the camera back on.  It is, to my knowledge not a buffer issue, because I use VERY fast CF cards.  I had the same issue with my 5D2.  It is bizarre and Canon can't offer an explanation.

I owned and used two 5D II and now two 5D III for years as a photojournalist. I've never experienced this behavior. My first thought was that it was a card problem.

Are you using the SD card slot? The SD slot is crippled on the 5D III but, of course, that is not a factor on the 5D II. I assume you formatted the cards in the camera. I format before every single assignment.

These fast cards--what cards are you using? That is the only thing I can think of. Good luck!

If you search, you'll see a few instances of the LCD display starting to flicker after installation of magic lantern. That's why I asked

Interesting issue. I also have never experienced any issues in 5D-series cameras, 5D1 (mirror never fell in my copy but still sent to Canon for a preemptive fix and sold later), 5D2 (converted to infrared) and 5D3.

I use Lexar Pro 1066X 32 gb cards, and have never loaded Magic Lantern.

Re: Card access lamp on?

Hi, When the top display is blinking does the card access lamp (below the quick control dial) show any activity - on or blinking?

How reproducible is the problem? If it is intermittent it will be more difficult to isolate.

Have you tried changing the lens or cleaning the contacts on the lens you have?

From what you have told us it looks like your 5D3 will need a service  If you try the suggestions from other posters and record the results you will have more data to tell Canon what the problem and what you have tried - you may even solve the problem.

Have your lens checked!

A lens with an intermittent problem will cause your problem.

It did for me!
