Possible Canon 7D fault

Hey guys i just bought a 2nd hand canon 7D it at first glance all seems fine but after taking a few photo's on it i decided to have a closer look on my computer when i zoomed into the images i noticed alot of thin black lines on them, ill upload them to show you any ideas what this is? does the camera have a fault? or need an update or somthing?

Many Thanks

Sensor is probably on its way out.

here is another

what program were you using when you did this zooming in?

Adobe photoshop CS6 but i can also see the lines on the LCD on the camera when i zoom in

Never see anything like this. If it is the program then probably there is something wrong with the camera. You know how many shutter actuations has?

It's probably time to contact Canon to get the camera repaired. First, though, try a new memory card and see if the problem disappears.

i ran a check and it showed 1760

possible other thread with same issue

What did you use to check the shutter actuation count?

EOSCount.com it was recomended by some forums

This^

Does it do the same with a different card? Looks like more of a camera/sensor issue but you never know, maybe there is something wrong with the card.

sadly right now i only have the one Compact Flash card ill try a friends now and let you know
