Sensor cleaning

I searched around and around and couldn't come up with much info.
so does anyone know how to do this or has anyone try to do this on a DVX100A or is this a job for the electronics dude?

I'm seeing some cloudy looking spots/dots on my footage when the light hits the lens a certain way, typically outdoor shots.
 
100 percent a job for the "electronics dude"!

To get anywhere near the sensor you will basically have to take your whole camera apart, and then somehow break your way into the lens assembly, and even if you did manage that, attempting to clean the sensor would probably do more harm than good as its such a delicate component.

Are you sure its not dust on the inside of the lens rather than sensor that's causing the problem? I have a similar issue with my DVX; there's a single speck of dust on the 2nd lens element, however it only ever shows up in bright sunlight, and I've found that by using a wide aperture with 1/64 nd it will not appear 99 percent of the time (and if the shot is still over exposed just knock the shutter speed up). Not the most convenient way of doing things, but it's a solution that doesn't cost any money...

If your camera is still under warranty you should have no problem getting it repaired, however if its not, this kind of thing could be very expensive to fix as who ever repairs it would probably just replace the whole lens rather than go to the trouble of cleaning it.

I read in a thread on this forum (which i cant find again) that its possible to physically shake dust and grime of your lens elements, but you have get your camera into a cold enough state so that the moisture that's holding said grime onto your cam freezes then all the crap should just fall off, however I'm not to keen on the idea of wantonly sticking a camera worth 1000's in the freezer for a couple of hours to experiment with this theory...
 
Josh,

thanks so much for elaborating on this issue for me and those who looked and had no answer. I've seen tutorials on cleaning digi still cameras, but nothing on video, so I guess I'll just deal with it as I have cleaned the exterior portion of the lens and covered it up with a uv filter, but still see those dreadful spots from time to time.

your explanation makes perfect sense. my electronics guy is reasonable, but it does seem like an extensive job that I am not willing to try and now that you explained the procedure, again I think I'll just deal with it and try not to shoot directly into light whenever possible.

I'm sure you'll be an asset to this great community here...and i hear you loud and clear about putting the dvx in the freezer, just the thought gives me the chills LOL.

thanks again and keep it reel
