Nikon D5100 Distorted Pictures Green and Pink Color

There were green and pink patches on the photographs taken using my three months old Nikon D5100 DSLR. If I would click 10 photographs the problem occurred in 2 or more photographs.

I googled the below text phrases to know more about the problem and eventually to solve it by any means

Searches turned out to be useless, the same problem was never reported or discussed earlier. Then, I contacted the Nikon Technical Support online; raised a service ticket explaining the problem. I got the below reply for the ticket.

Immediately I bought a new SD card (Nikon approved card as mentioned in manual) and took couple of shots. But the problem still showed up :(

I had no hope and no clue about the problem. After couple of days I took my camera to the Nikon authorized service center.

After 3 days I collected the camera and they have replaced the Camera SENSOR. The charge was Rs 1x,xxx. But since the camera was covered under 2 years standard warranty I repaired the camera without any expense. 

Nikon D5100 Firmware Update 1.01

This service provides software for upgrading D5100 A and B firmware to ver.1.01. This software allows for simultaneous update of both A and B firmware to the latest version. If this latest firmware version is already installed in your camera, you need not proceed with download or installation of this Firmware Upgrade. Current firmware versions can be verified from the Firmware version item in the camera's setup menu.


Updates/modifications enabled with A and B firmware Ver. 1.01:

• An error where the card may not have been recognized when some memory cards were used has been addressed.
• When "Selective color" from the retouch menu is performed on a picture taken with the image quality set to "NEF (RAW)+JPEG" and an image size of "M" or "S", the edges of the image may not have changed color. This issue has been resolved.
• When "Metering" was set to "Matrix metering", the exposure mode set to "M (Manual)", and the HDR exposure differential set to "Auto", the exposure differential was fixed at a value equivalent to "2 EV". This has been changed to enable automatic adjustment of exposure differential so that it is appropriate for the scene.
