I have followed all the directions for connecting the 7" display to the board and to the raspberry pi. I cannot get any type of picture to display on the screen.
I have tried multiple power supplies(all listed at 2amp) but that did not help. I tried inverting the display cable but no help. I have powered the display board and the raspberry pi separately(I removed the jumper wires first) but no luck. Could it be a bad display module board or bad display? The display board does pass power through to the raspberry pi but I have not seen any lights on it(are there any)?
