I take say 5 images in RAW, download via cable to computer using Nikon ViewNX2 software. As soon as I edit an image I get verticle or horizontal coloured lines through the image. I always reformat my card in the camera and this has happened to old cards as well as brand new cards (Sandisc 4& 8GB Extreme). Uninstalled Nikon Software and did a scanreg to remove remnants from Registry, Re-installed software from Nikon website. Carried out a computer System scan and sent to Nikon (all fine). Firmware up to date. Camera takes good pictures but sometimes after downloading images are corrupted or become corrupted with editing, sometime ok. This also happens in Jpeg.
Will be sending camera to Service Centre, but dont think its mechanical. Whe I noticed it there were affected images and unaffected images side by side. Anyone any ideas.
