A way to get rid of stuck pixels on a Canon 40D
by Mice007 on jún.18, 2008, under Other
After I bought my new Canon EOS 40D and played around a bit I found out that i have a bright white pixel near the center of the captured image. It is called a stuck pixel, or sometimes dead pixel.
I was not happy about this because i thought it meant that I have to send the brand new camera back for a replacement or repair (with a software remapping process to calculate the average brightness and color value using the surrounding pixels around the stuck one).
I thought I’d take a chance myself and google the issue, and deep in a forum I found something, something interesting: It is possible to do this remapping process from the camera itself! And it is easy, just charge up the batteries and go to the menu and initiate a “Manual Sensor Cleaning” then wait about a half minute then turn off the camera: if you’re lucky the stuck pixel is gone! I’d taken several before and after photos, and the stuck pixel really is no longer there…. the problem was fixed!
So if you have a Canon 40D with a stuck pixel or dead pixel give a try to this solution, maybe it would save you a few days or weeks of being without the camera.
UPDATE: According to my visitorts it seems this method works on Canon EOS 400D / Digital Rebel XTi, Canon EOS 500D, Canon EOS 50D and Canon EOS 5D Mark II too.

Worked great on a DEAD green pixel on a brand new Canon 40D.
I was afraid I would have to use the warranty on this thing.
Thanks!

Very helpful, thank you very much.
It fixed my red pixel(hot pixel).
all I did was the following (as you’ve explained):
- charge battery to full
- remove the lens.
- put on the cap in place of the lens, and make sure its all dark and no light is getting to the mirror.
- Menu -> Manual sensor cleaning -> ok
- left it do it’s job for 45 seconds
- turn off
- turn on
- WOOOOT!

Thanks for letting me know

Man this so saved me. I am going to go to Burning Man in about 6 weeks and plan to take alot of night shots and the last thing I wanted to was send in my 40D and pray I get it back in time. I did run a pixel checker and it said there were 65 dead pixels and 40 hot ones. I noticed that they would start to show up anything over over 1/3 of a second. I followed Kagami directions ( i think I let it “clean” for like 4 minutes though) worked great.
Number one best blog info tip TO DATE!!!!

Thanks for the feedback, good to hear that this post helped you out

OH MY GOD. I have been cleaning the red pixels off of my images manually in post for over a year now. I just tried this method and it fixed my sensor! Thank you so much!

Thanks a lot.
It worked on my brand new EOS 500D / T1i with a double purple pixel.
I still see a couple of odd coloured pixels if I take a 30 sec exposure / iso1600 photo with the lens cap on, but they do not show with “regular” (sub second exp.) pictures.

Didn’t work for my brand new 450D with 10 white, 2 red, 3 blue/purple pixels.
Method tried:
- Manual clean with lens and lens cap on, viewfinder covered.
- Manual clean with body cap on, no lens, viewfinder covered.
RAW n JPG photo were taken with iso 100, 30s, LENR=off. Both still showing the bad pixels.
Thanks for the info though, glad it help others.

Thanks for the feedback. What firmware do you have on the camera?
március 27th, 2010 on 01:07
I've heard it's worth trying again, for a longer time manual cleaning before you turn off your camera.

Thanks, it worked perfectly on EOS 500D.

Thanks for the feedback!

Just tried this with my 450D and it worked, the only thing i did differently was to take out the battery for a few minutes after doing the manual clean thing and the turning the cam on and off.
Took some samples with lens cap on and no more Stuck/Dead/Hot pixels. Thanks for the tips.

I have a Conon 50D. After a backpacking trip I found some what looked like dust looking through view finder. Strange….I changed lenses and found it was seen through all my lenses. There was something on my mirror. I tried to blow it off, then wipe it off. No good. While it did frustrate me, it didn't show up on my pictures.
I found this blog posting and thought I would try it. It worked!
This was a great bit of info.
Thanks.

Well you're lucky then because that was a dust in your focusing screen in the viewfinder and during you played with the camera it felt off.

Brilliant. I have a new 500D and I had a red pixel in the center of my photos right from the 1st 10 photos of the brand new camera…
I tried out the steps and BOOM… it has vanished now… am quite a relieved man now. Thanks a ton for the post…

Worked great on my 500D. I had taken about 6000 pictures before 3-4 white pixels started showing up on high ISO-settings. Now they're gone! Thank you so much.
január 20th, 2010 on 21:59
thanks bro its working!

Didn't work on my 500D. I took 3-4 pictures after I put it out of the pack and I found one white pixel on each of them. I tried all methods described here (post & comments), but unsuccessfully: the white pixel still persists.
What can I do to solve this problem?
január 31st, 2010 on 19:00
Are you seeing the white pixel on the image itself (after uploading to computer and zooming into the picture? If no then it may be on the camera's LCD screen. Maybe you should check the firmware version (make sure it is the latest) or try to remove the main and the backup battery for a few minutes and try again the whole process.

Thank you very much. Worked perfectly with my brand new 550D. Stuck double purple pixels gone. Yes, now I am completely happy with my new toy.
március 3rd, 2010 on 22:29
Thanks dear. It worked for me on Canon T1i.
március 27th, 2010 on 01:05
Thank you – you saved my new canon 5d ii from being returned!
április 2nd, 2010 on 21:24
Worked on my 550d. Tnx
április 26th, 2010 on 20:14

I LOVE U!!!!!!!!!!!!!!!!
május 23rd, 2010 on 18:44
Lol! I’m glad it helped
május 30th, 2010 on 21:54
Did work for my 550D (1 pixel). Thanks very much!!!
július 5th, 2010 on 23:02
I did work for me, not just for one camera but for two: T1i and T2i. Both of them showed one hot pixel ( green and violet respectively about the centre of the image) and in 30 secs. just disapeared. I tried in every resolution for video and photo… they are just gone. I'd like to thank for this valuable tip and ask, if I may to do so… how it works?
