کسی جواب منو نداد، اشکالی نداره خوب خودم دست بکار میشم.
یکم تو اینترنت جستجو کردم ظاهرا این مشکل عادی هست. یه موضوع پیدا کردم که مشکل منو حل کرد منم مثل نویسنده نمیدونم چرا اینکار مشکلو حل میکنه اما بهر حال جواب داد.
After shooting with my Canon 50D for a while i realized there was a hot blue pixel in all pictures, i was about to send of my camera to canon to get that fix. but i was postponing sending it off because i didnt want to be left without a camera, so after some searching i came across a very simple and harmless quick fix. I was surprised that it worked, but it did!

Hot Pixel Fix for the Canon 50D worked for Rebel XTi as well [update, from comments i understand that it works for the Rebel XSi, Rebel T1i, rebel T2i, 7D, 5D M-II] :
- Remove the lens and put the body cap in place on the camera [not sure if this is a must]
- Put the camera in to “manual sensor cleaning mode”. It is the same for both the 40D and 50D – Press the “Menu” button, then select the middle “yellow wrench” tab, then “Sensor Cleaning” then “Clean Manually”. You will hear – the click of the mirror coming up (so you *could* be using a swab on the sensor – but don’t do that – leave the body cap in place).
- Leave the camera in this mode for 30-60 seconds, I kept it this way for closer to 60 seconds.
- Power off the camera off – you should hear another click as the mirror drops down into place
- That was it. Test the camera and see if the dead pixels are gone – they were for me.
Thanks for reading!
I still have no idea why/how this works, but it does. I was about to send in my camera to Canon to Fix this problem, but this was way easier!
