7" touchscreen sanscreen SSD1963QL9 controller Mega 2560 not working

Hello everyone! I'm not really an expert programming on arduino. I bought a 7" touchscreen+shield on Amazon and I'm trying to make it work with an Arduino Mega 2560. I'm trying with the UTFT_ViewFont example code that comes with the UTFT library butn I can't make it work. The controller in the back of the touchscreen is SSD1963QL9 which I've found is not included in the library, although I've tried to make it work changing the controller in the following line of the code, I haven't found one that works with my screen.

UTFT myGLCD(ITDB43,38,39,40,41);

ITDB43 is just one of the many I've tried.

Thank you!

Hi - I have got the same problem: 4.3"" TFT and no function - no LED no display.
