I have an eos 6d and all buttons, except backlight simply

Customer Question

I have an eos 6d and all buttons, except for the backlight simply quit working yesterday. The top and back wheels both work and will change time and aperture in Manual mode. I shot some 60-70 images yesterday before they quit, and over 150 images on Monday. I've changed lenses, batteries, flash cards. The sensor cleaning message comes up on the display when starting or shutting down the camera. Unfortunately I can't tell for certain what firmware is on the camera (menu button doesn't work), and hence also can't flash the latest firmware. Any help would be appreciated!

Hi, thank you for contacting JustAnswer.com. My name is***** will do my best to provide the right answer to your question.

It's possible that your camera had a static discharge susceptibility episode.

Were you wearing woolen garments at the time the problem started yesterday? or at least a woven sweater?

Those garments tend to generate static electricity, which is then discharged into any device you touch carelessly, through your fingers. The discharge may be too faint to feel, but still in the hundreds of volts even if very low-powered, and can cause problems varying from temporary eccentricity of the device, up to and including permanent damage to its functions.

Was the weather hot yesterday, also? if so, that could have affected the camera for the worse, also.

Try removing the batteries, and leaving the camera on a (dry, non-humid, non-dusty) shelf for overnight. Then put the batteries back in and try the camera again. This would be called a rest-reset, and might help. If not, a rest-reset of two or three days could be tried also.

How old is the camera? in months or years since you bought it.

Has the camera been dropped or otherwise subjected to mechanical shock(s) in its lifetime?

Has the camera been operated in or subjected to, temperatures below 32 degrees F (freezing point) or above about 100 degrees F ?

Has it ever been subjected to a humidity higher than 85 % or gotten wet ?

Has the camera been operated in a gritty or sandy environment, such as a beach, a seaside, a construction site, or the like?

The camera was purchased in October 2014. It is primarily used for my travel photography, so it see's most environments when shooting. It is well protected however with rain jackets, and sun/sand protection as appropriate. The day it quit working properly we were at the beach in mid-80's temperatures, the camera was protected in the shade and from sand (although the 6-D shouldn't have a problem with this anyway). it's never been dropped, 80's, no sweater hence no static. I've changed lenses as well. I'm now charging a full set of batteries which will take a couple of hours and I'll try and jump start it again. I'll also format a fresh card in my 7D as well to use with the troubleshooting. It's unfortunate there's no way except through the menu to hard reset the camera, at least that I know of or could google.

These Canon cameras generally only have menu-mediated resets, which actually are just resets of the Settings.

I'm glad to hear that you have taken good care of your camera.

Let me know if fresh, freshly charged, batteries have any good effect.

Also remember my advice:

Try removing the batteries, and leaving the camera on a (dry, non-humid, non-dusty) shelf for overnight. Then put the batteries back in and try the camera again. This would be called a rest-reset, and might help. If not, a rest-reset of two or three days could be tried also.
