Damaged Sensor?

I have a problem with my camera, i get these wierd lines running through my pictures, it only happen when the picture is dark.

It goes through the top (landscape) and the left side.
Have anyone had this problem before, or know how much it would cost to fix it?

Its a canon 5d Mark 1, no warranty

looks ****ty to me .
might consider adress to closest canon service.

Is that with flash. Maybe your shutter sync speed is to high or your shutter is failing. I don`t think it a Sensor issue.

Are you using Cactus triggers with the 5D?

Some models has issues with the 5D mrk1

This guy did some modification work to cause it.
*******
so I did the cactus radio trigger mod (antenna on the transmitter) and to my surprise I discovered the following effect:
the bands occur not only when the transmitter is mounted on the hotshoe, but also when it is near the camera.
the affected sensor was the full frame cmos in canon 5d
the smaller sensor of canon 20d was also affected, but to a lesser extent, (bands are clearly visible after boosting the raw brigntness adjustment up a one stop. see here
the mod I did was basically aKuster based mod - the difference is that I used a copper TV wire instead of an antenna - so it would be cool is someone with that mod and a 5d could check if the dedicated 433 mhz antenna mod also produces this effect.

the good news is that it is not a permanent damage - at least not after about 200 exposures,

anyway - for me that make the mod unacceptable, even if I finally reached a 99% reliability in studio conditions.

Found a better link. Apparently, it's not only the modded ones

Check out the banding in http://photodecal.org …/main.php?g2_it​emId=46122

Looks pretty much the same as the OP's to me?

Another question, just in case--did you try a different CF card?

Yes i have tried different CF's..
ABout the cactus issue, that MIGHT be the problem.. I used a cactus for that shot there, but i cant remember if i used cactus on the other shots.. I might have to do some testing again

The cactus is a friends, so i dont always use it..
Thanks for the info, i will come back with more!

looks like RF interference to me.

My problem looks very much like the ones described in the other posts.. Thanks guyes, you saved me alot of money :P

No. Not really. Can't you feel that burning, allmost intolerable urge to buy some Pocket Wizards instead. You know you want them. You neeeed them...

I'll tell you I am getting PW's when I get my lighting setup. I've read enough about the quality difference between Ebay triggers and others. I may however be shooting PCSync for the next while.
