Thanks for your reply, now i wanted to start working with my display and i stuck with an black screen, no backlight at all.
I downloaded the UTFT 2.0 lib and have installed the latest arduino software.
Then i startet the UTFT_320x240 example and changed the LCD setup to:
which should be the right setup for my display, i also checked the hole UTFT documentation.
the only thing i noticed is that on the front bottom side of the display where the cable for Touch and the display itself are mounted the area got a little warm.
I should mention that my displayglass cracked a bit but i cannot believe that know not even the backlight works.
Who knows what to do or has some advice?
