2.4 tft display not working

Hi
I recntly acquired an arduino uno r3 and a 2.4 tft screen module.
I followed a tutorial on youtube and when it came time to calibrate the screen with the touch screen demo the screen doesn't turn white and doesn't allow for any input.

Ps. I am new to arduino

Thanks in advance

Please post a link to the actual display you have bought e.g. Ebay sale.
Please say which library(s) and which tutorial(s)

If you can't find a link post a photo of the pcb side of the display.

David.
