Cost to replace a sensor?

I have an opportunity to purchase a 7d with a bunch of dead pixels for $500.

Has anyone received an estimate from Canon to replace a sensor or have any knowledge of how much replacing a sensor will cost?

how many pixels are dead? if you use lightroom you can map them out and not worry about it.

Not sure how many. The ad just mentions several dead pixels.

I will be using this for pictures and video, so replacing the sensor is something I will probably want to do.

dead pixels on the backscreen LCD you mean? personally I wouldn't be bothered by dead pixels if the price is right.

I almost feel that I have some bad pixels just never done anthing about it. Not sure if they are dead or not or if they are called "Hot pixels" they jump around some and only noticable at iso 12,800. maybe it's just from being at the max?

Best bet is to call Canon up and ask for a quote and then figure a 7D goes for $950ish these days, subtract the difference and see how you make out.

having a quick look around for parts info, found one for $340 here

factor in a couple of hours labour for installation, programming & calibration. Probably won't get much change out of $500 to fix.

Thanks for that link.

Hmmm...$340 for just the part. I'm guessing a canon repair shop will be able to get the part cheaper, but labor will make up all of the difference plus more.

This puts the total price at $850+. Probably not worth the hassle.

ask to see some sample images, you may not even notice them. video may be another story but for images they are very easy to fix and get around.

You can have the 7D automatically map out the dead pixels. Unless there are a ton of them there's no reason to replace the sensor. It's quite easy to do:

1. Turn on body and leave on body cap, no lens.
   
2. Turn on live view and let it sit for about two minutes.
   
3. Navigate through the menus and perform a manual sensor cleaning.
   
4. Let it sit for at least one minute and then shut the camera off
   
5. Camera is automagically fixed.

Not exactly fixed. This procedure only causes the hot/dead pixel to be mapped out. It is filled in (interpolated) from the surrounding pixels. As long as they are few (0.1% or less, I imagine) and spread out, you'll never notice them in any print.
