I was out shooting with the 7d today, I was shooting raw,in the middle of some fast action, a loon eating some fish, the camera locked. The top display stayed on. I noticed the auto focus started freezing right before this happened. I could turn the camera power button on and off, nothing would happen.
I pulled the batteries out and clock battery out, after a couple mins replaced batteries, back to the action all seemed fine. We continued shooting, my wife with 60d, once it settled down I noticed that my LCD would not come on to review my images. I freaked thinking maybe it was not recording to the flash card. I checked all ok.
Removed the grip and clock battery, left for a couple hrs, reinstalled set clock all seemed good.
Went to shoot a sunset tonight noticed no LCD again>>> or wait, in auto modes green bad and ca, all fine you can shoot and play back, in all other modes from P on through C3, you can shoot but not review, also no other buttons on back function, if you shoot shots in any none auto the pictures are fine if you flip dial back to auto mode you can review.
Live view button does not work either, video does not work.
Can I reinstall software its been good even the GPS has now been working fine, or any other ideas??
Thanks in advance.
