7D buttons not working

[cschwartzy]

Hey all. I was out shooting some college football today (video) and the camera was working fine. Then all of a sudden I noticed that my record button was not working. Once I realized this I look closer and noticed that none of the other buttons (menu, iso, playback etc..) were working. 

This evening I sat down and tried to research the issue. I didn't find much. I took out both batteries and even did a software update. The only mode that buttons actually work in (Menu, play back etc.) is Full Auto. If I put it in any of the others the buttons become non responsive. The only thing that works in manual is the wheel by the shutter button but instead of it doing the Shutter, it controls the aperture, oh that and the light button. 

I really have no clue what the deal is. I am guessing there is an issue with the camera and it will need to be sent in. Anyone have any ideas?

Anything is appreciated!

I had a similar problem with my 7D1, especially when it got wet due to getting splashed or sweaty palms from heavy use. It ended up needing a new shutter button and a whole new back plate assembly. I was told the was some corrosion in the buttons.

Hi , unfortunately i have exactly the same problem. Could you please let me know how did this end up? Thanks

In case anyone is still looking and has this problem.

I had no functioning buttons except top display light, pop up flash and shutter. I'm CA I could get into the menu but not in M, Tv, Av. Tried leaving the battery out, trying without CF card and nothing. Put into C1 and got the menu up. Couldn't reset settings in that mode.

Could also get the menu up in bulb, B, mode. Reset camera setting from there and everything now works.

Would also like to know what happened as I am now finding the same fault and can it be repaired or do we just toss the body overboard?

I just had to look up my video on how I fixed it. But.... If I put it in bulb mode I could get the menu button to work. Then I cleared all camera settings and it started working. May be worth replacing the watch batter inside the battery compartment also. Mines been working ever since.
