5D MarkIII Screen not working

[CourtneyGoldman]

My screen isn't working. It doesn't matter if I press play or info or any other button, nothing comes up. However the *Sensor Cleaning* message comes up, so it isn't just a dead screen. Any ideas?

Remove the lens and any accessories.

I've done that. And tried other lenses and cards and batteries. No help.

Sounds like you have bad board or something.  Time to contact Canon Support.
