This looks like a hardware problem. One cause can be the cable that connects the video chip to the screen has been pinched/damaged, causing the display to show the color bands. More likely, in my opinion, is the video chip itself is damaged from overheating or the memory attached to it is going bad.
If possible, take it in to a service center for diagnosis. I do not think there is an easy software fix or patch that you can do to solve this. It will likely involve a bit of cash and getting the motherboard and/or the screen replaced.

I sent the same photographs to authorized Apple service centre but they are not replying, or answering my phone calls.

I done the basic hardware test, holding down the D key while booting. There were no hardware problem in the result.

I think what you are saying is right.

I will do the test again using "Perform extended testing" option. and will post the results.

I tried reinstalling the OS but not happening.
