Burning the censor's pixels

Hi guys,

I've just recently entered the interesting world of DSLR videography and already problems start to arise...

A few days ago I bought a Canon t3i from a local vendor. Once I got it home, I immediately started testing it and shooting all over the place. But once I uploaded the footage to my computer, I was shocked to find a burned pixel in all my shots. Now that might not sound like such a big problem but because the camera downscales the image from the sensor's size to HD, somehow that one tiny pixel because really big and really distracting in video.

The problem is that I bought the camera from a local vendor that gave out it's own warranty and not the official supplier's. And the store's warranty clearly states that if only one or two pixels in the sensor are damaged it will not replace the camera.

Now I can either cough up the money to pay for a new sensor to my new camera,
OR I can find a way to burn two more pixels in the sensor and apply the warranty.

So my question is - Does anyone have a suggestion how to slightly burn a DSLR sensor?:huh:

Thanks
 
There are "hot pixel" fixes posted all over the net that may or may not work (seems they are hit or miss). Usually involve repeated Sensor Cleaning. You might try that.

Go outside, put 135mm on it, put it on a tripod, point it at the sun, put on really dark sunglasses and focus, switch it into live view and walk away for about 20 minutes.
 
i have a 5DmkII and it has a small cluster of hot pixels when i shoot video above 1000 iso that can be seen on some shots where the hot pixels are in a dark area. hot pixels for video cant be fixed by the user although hot pixels for the photos from the camera can by certain procedures.

my first 5DmkII was worse and i took it right back to my local store and they swapped it out right away. too bad you dont have a warranty. im not sure Canon would swap it out anyway for just a hot pixel. i buy a ton of gear from my local store so they took care of me.

this is what i use to fix the hot pixels. its fast and works in realtime.

dude, I know he's asking a question that's been answered on these boards a million times, but giving advice that could kill his camera ("point at the sun and leave it there in live view for 20min") is some nasty retaliation!! anyway, here's the usual solution for dead/hot pixels: take lens out and place the body cap on the camera. Go to M picture mode. Go to menu and look for sensor cleaning. Choose clean manually. Hit ok and wait 30 seconds. Then resume regular use. It will get rid of the dead pixel - http://www.dvxuser.com/V6/showthread.php?201351-uh-oh-is-this-a-dead-pixel-in-my-T2i/page2
 
Read the first post again. The op asked how to kill his camera, Norman. The warranty only kicks in if it's really dead, he said.
 
oh, sorry, I didn't get that (I thought he only wanted to create a couple more dead pixels, not utterly destroy it!!) - sorry, my bad - but still, I'd think fixing it is a better option, it only takes a minute

yup, norman bates post will most likely fix it in a minute or so, I would try that before you fry it completely.
 
Wow! Magic!!!!

I didn't know there was a solution for dead pixels. (I also didn't know the term 'dead pixel' so I didn't find something in the forums...)

Anyway, thanks a lot. Saved me a heap of troubles. :)

Thanks Green Goblin.
