Customer Question

I upgraded my canon 7d mark ii to the 1.0.4 firmware now it makes a grinding noise and you can barely hear the audio on playback of videos. What happened? I was working perfectly before then.

Hi there,Please try the following resets, then try updating the firmware again:First, try a Power Reset:1. Make sure the camera is off, and then remove the battery, memory card, and lens.2. Close the battery/memory card doors.3. Turn the power switch to the "ON" position, and then press and hold down the shutter button for 10 seconds.4. Release the shutter button, turn the power switch to the "OFF" position, reinsert the battery, memory card, and attach the lens.5. Power the camera on.Next, try a Settings Reset:1. While the camera is on turn the mode dial to "P" (Program mode), which allows all menu options to become available, then press the menu button.2. Move across the top of the menu to the last wrench tab. (Yellow tabs)3. Go down the menu list to "Clear Settings" and press the Set button.4. Choose "Clear all Camera Settings", and press the set button.5. To complete the reset highlight "OK" and press the Func./Set button again.6. Next, move over to the Custom Functions menu list.7. Reset the "Clear all Custom Func." settings as well.Before attempting the update again remove the lens from the camera body. Let me know how it works out....
