XDCAM Bad Pixels
on Apr 13, 2007 at 12:15:44 am

I have an F330 and an F350. Each has a couple of bad pixels. My Sony tech told me to black balance as many as 15 times in a row and that will clear them up, and they shouldn't come back after I do that. Is this true?

He said to keep an accurate record for each camera of where the bad pixels were. If they return, that's serious, and in that case I should send the camera in to have the block replaced.

Does this sound correct? I thought the repeated black balancing cleared bad pixels temporarily? The reason I want to be certain about this is that both cameras are under warranty. I don't want the warranties to run out then find out that I should have had the blocks replaced the moment I discovered the bad pixels.

Any input is greatly appreciated. Thank you.

My 330 had a large bad pixel or group of as well. I was told the same thing, black balance. Mine went away and haven't come back yet (5 months). Let's hope this is the way it works and they don't come back! A bad pixel in HD is really noticeable!

I agree. My 350 had a white pixel back in september 2006 when I got it out of the box. 3-4 times black balance took care of it and I've never seen it since.
You should be okay if you don't have the odd one out with a really damaged block

Good luck,

Ron

The correct process is to black balance once in each of the gain positions. We use 0, 6, and 9. Before you fix it, make sure you record some footage and pull a screen shot to send to your sales rep for clarification later should the block become unusable after the unit is out of warranty. If you have something recorded to tape, that could work as proof. We had a pixel group blow out on a DSR-500 right in the middle of a Kenny Rogers concert and we had it fixed in less than 60 seconds.

This works on all Sony 2/3" digital cameras.

Don't yell at me but black balancing also worked on our Panasonic HDX900 lit pixel problem.

That is really great news, Ray. For years, the only solution was to replace a very expensive pick up block.

So, I guess what you're saying is that there is hope for the Panicsonic line of products after all.

Had you heard that Matt DeJesus has two RED cameras on order? If not, consider yourself advised.

I bumped into Matt at NAB. He told me he had a low number, around #18 or so. I expect to drooling over his Red camera this summer.
I can't justify it but I am real curious.
Later,
Ray
