I'm in the same boat as Roin316 in that I a bought a combo screen, shield and mega(Serial SPI Arduino 7"TFT LCD Touch Shield RA8875 for Mega/Due/Uno) from BuyDisplay. It works great right out of the box with the code that was preloaded into the Mega. So I had an extra Mega board that I swapped out and loaded the libraries and example code from the website. With the website code the display is dead. No backlight, only power LEDs light up. Have tried several different examples all with the same result. As the display works with the Mega board purchased with the display and shield, there must be something different in the code on the website verses what was preloaded from BuyDisplay. One thing that I found that is different is the model numbers on the website indicate ER-TFTM070-5 and the model number on the board is ER-TFTM070-4. Does someone have suggestion on where I might find the code the was shipped with the Mega from BuyDisplay?
