Canon EOS 6D: Canon eos 6D buttons not working constatly trying to focus

Sat, 29 Jul 2023 03:18:50 -0700

Hi, I have a problem with my Canon 6D. It was working fine and one day when I turned it on it started this behavior: when turned on it starts focusing but no buttons are pressed, Top lcd shows information as unusual, AF mode, Drive, ISO buttons not working, only backlight button works, shutter button works...

I've tried reset it by removing battery and card with no succes, even tried removing internal clock battery and cleaning all the buttons, nothing changed, tried top cover with all buttons from another 6D still same results, I think it's corrupted software or motherboard issue it is running firmware 1.1.2 I've tried update with EOS utility because usual method with SD card is not possible because menu button doesn't work as well but in EOS utility I get a error message "update not possible, camera busy"

Has anyone had similar problem or know how to "force update" it?

Canon EOS 6D: Main dial replacement, there's some grease?

Sun, 25 Dec 2022 03:01:25 -0700

I was about to replace the main dial (next to shutter button) but I figured out there's some white vaseline-looking stuff between these parts there. What stuff it is actually? I think it would be wise to clean the old greases off at least, so I probably need to put some new grease there.

Canon EOS 6D: How can I hack the USB of my Canon camera?

Fri, 22 Nov 2024 19:11:48 -0700

I damaged the Mini USB port of my Canon EOS 6D and I’m trying to get a few cables out from the PCB directly to comunicate with the camera, I soldered a few cables for VUSB, GND, D+ and D- but when I plug the camera to the PC is not detected…

I saw the Data signal with my scope and I see some data bursts sometimes but nothing on the PC… What m I missing?

How can I recover the USB comunication without changing the whole PCB?

Canon EOS 6D: Battery door is stuck

Wed, 13 Oct 2021 15:39:32 -0700

Help! My battery door is stuck, this happened because when I was trying to put the battery door back in, it got stuck somehow…

I removed it so I could put a battery grip on it…but when I tried to put the battery door back I accidentally got it stuck somehow, and it’s gonna be costly if I can’t get it fixed myself.

I uploaded a video to Youtube to show you guys what I mean.

Canon EOS 6D: My Canon 6D is not working properly

Mon, 26 Apr 2021 00:00:00 -0700

My Canon 6D is not working properly. I noticed my coloring is off, pink tones. I also have trouble shooting in low light with a 50mm 1.4. It is like not enough light is coming in even though I know there is. The images are blurry and and coloring is off. Every time I search this it says user error, I have manually set all my settings. My partner who does photography with me tried and she can shot fine with all the same settings and lens but my camera will not budge. Took it to repair shop, they said either communication error between the sensor and main board or main board is bad. Any thoughts?

Canon EOS 6D: How to clean 8-way controller?

Tue, 16 Mar 2021 14:40:58 -0700

Down-direction of the 8-way controller in my 6D does not work anymore. It's behaviour has been degrading slowly so the problem could be some kind of dirt between the contacts. Is there a way to clean it without opening whole back cover? If the back cover has to be opened using the guides here is there a way to actually access the contacts of the 8-way controller and still be able to put everything back together?

Canon EOS 6D: Optical viewfinder display went black

Sat, 26 Dec 2020 11:39:00 -0700

My Canon 6D status bar at the bottom of viewfinder display didn’t turn on. I cannot see ISO, shutter speed, etc insider the optical viewfinder. However, the 11 focus point sill turned on with ‘Red’ once in focus. I recently replaced the Shutter Curtain myself, hence, opening up the Canon 6D is fine for me. I would like to know where to look if I am going to open the 6D and fix this ViewFinder display issue?

Also, the WiFi is not working as well. Can I get the WiFi module from T6i and replace the 6D WiFi module?

Thanks!

Canon EOS 6D: Replacing Mainboard on Canon 6D

Thu, 20 Aug 2020 05:07:40 -0700

Dears engineers, photographers and friends,

If replacing mainboard of Canon 6D, does the camera need to be calibrated? I see that the CCD board is screwed to the chasis, so is really calibration needed if just replacing the mainboard?

Any advise is appreciated,

Thank you!

Canon EOS 6D: Has anyone replaced or repaired the Mode Dial?

Tue, 23 Jun 2020 09:16:39 -0700

Our 6D was loaned out and when it was returned the person borrowing it told us that the mode dial plate had come off, but she just put it back on. Now, however, the mode dial itself seems to be locked. The button depresses unevenly and won't seem to go down all the way to unlock allowing it to turn. Any suggest fixes or guides? I'm reluctant to pony up $350 for a Canon repair for what seems to be a small issue.

Canon EOS 6D: Overexposure in top right corner

Sat, 23 Mar 2019 07:07:07 -0700

For a couple months now, every photo I take with my Canon 6D has had an angled strip of overexposure in the top right hand corner in the exact same spot every time. I don’t know exactly how to google the issue to find possible solutions. I have a couple examples attached below. Could it be somehow that the shutter is getting stuck? Has anyone else experienced this issue or have an idea for a solution?

How do I use a high precision micrometer to replace the sensor and make sure I can get perfect focus once I put it back? I'm not actually sure what I have to measure. Any guide or videos I can follow? Any recommendation on what high precision micrometer I should purchase?

Canon EOS 6D: What connector is this?

Wed, 22 Nov 2017 09:32:23 -0700

Does anyone know what the 10 pin connector is that sits behind the rear rubber piece on the right side of this camera? I'm assuming it's some sort of service port but curious to know if there's any ability to interface to it. Looks like most Canon DSLRs have some variation of this connector (number of pins varies)
