the line going down the middle ( you may have to zoom in abit)

Thanks Blake

If this is a closed lens/no light shot it looks like a column of bad pixels.

It could be, and looks like, a hot, stuck or dead, pixel.  If it is there are ways to map it out or discuise it.  They don't fix the pixel(s).  They just try to make it so you can't see it.  But I will guess that doesn't show up in normal photographs.  Does it?

One fix is remapping.  Set it is to run the manual sensor cleaning procedure for a minute with the body cap on. This resets the pixel map in order to hide the stuck pixels from your pictures. Works most of the time.

Another is post processing of your photos.

That's a whole row of dead pixels. Doesn't hurt to try the remapping trick used with single stuck/dead pixels (all sensors have a few).... but I doubt it will be effective with an entire row like that. Most likely, the sensor or another part downstream from it is going bad and needs replacement.

thanks for the fast replies guys.
i have just bought this camera second hand and was hoping it was a simple fix.

not the case it seems.

any ideas on what it would cost to get something like this fixed in australia?

If in fact it is the sensor, it is usually not worht repairing.  Probably way more than the value of the camera.
