New EOS550D - stuck pixel - amazed at Canon's response!

I bought a new EOS550D less than 2 weeks ago and, yesterday, noticed an anomaly on every image.

I blew this area up to 1000% and sent a copy to Canon technical service (NZ) asking how to fix it.

Before receiving an answer I spent a couple of hours online searching for possible solutions.

Google suggested it was a stuck pixel. The info described and showed exactly what I had. And pointed me to a page telling me how to fix it.

I followed that procedure and it was fixed in less than a minute.

Following that, an email arrives from Canon. I was expecting their experts to outline this procedure... but no! They want me to send this new camera in to their service department to be repaired!

Anyone else had the same kind of experience?

Haven't had the experience of dealing with Canon customer services but I have used a bizarre technique to remove stuck or hot pixels from a 400D.

It involved setting the custom function to allow manual sensor cleaning while keeping a lens attached! After the 30 second time frame, the mirror returned to its normal position and I fired off some test shots. Amazing the hot or stuck pixels had disappeared!

I'd be interested in hearing how you fixed your problem, even if Canon don't sanction it! Surely they must have wanted to do something else upon return?

No I have not have this experience - but if it's a hardware fault, then it will need to be sent to the repair centre.

(* I Believe*) Most manufactures have a standard where it's only considered a fault if a certain percentage of pixels are faulty - so if Canon are willing to repair the camera for a single pixel - then that sounds fair to me.

I don't know what the returns policy is with the shop you purchased from are - but as you have only have the camera for 2 weeks, you could enquire if you could exchange for another 550D.

You are right... set the camera to manual sensor clean (with lens still attached) and switch off after 30 seconds to reset mirror. Stuck pixel had cleared after that!
