    7" touch screen will not function.


      Not sure I'm in the correct section but here it is. I have a 7" touch screen that I tried to use with a Raspberry Pi 2B. the touchscreen does not want to power up (I assume this because there is no backlight?) I do have 5V and ground attached from the GPIO and i verified with a scope that i have the proper voltage. i do have various voltages on the display board on the touch screen. I have downloaded the latest Rasbian software and installed. I have turned on the SPI in the Raspberry Pi Configuration screen. so my question is: is this a fault with the touch screen or a software issue? the Raspberry works fine when connected to the HDMI and a TV. I even tried to put power to the power connector via a micro USB, still nothing.
