Lundin Thanks a lot for the advice mate.
I may be getting somewhere but I don't know if it is the right direction.
As you said I cleaned the library and kept only Adafruit libraries and ran Graphicstest.ino.
Bingo it says "unknown lcd driver chip c0c"
however going further with your advice I hardcoded all 5 types of drivers but yet no success.
It makes me wonder could there be another driver IC which we may have missed.
your thoughts are greatly appreciated.
Thanks in advance.
