Default Canvas 2 Colours - Engineering mode?

Hi guys. This is my first post here, though i have used it sometimes for reading things.

I just bought Canvas 2 Colours A120. but the engineering code * # * # 3646633 # * # * is not opening the engineering mode. all over the google, this code is being used for Canvas 2 , Canvas 2 plus , and other siblings of it..

I have even tried it on Canvas Fun.

Please tell me how to go to engineering mode in A120 Canvas Colours. or guide me how to unlock the TV -out in my mobile.

Thanks in advance.
