Can someone help me find the reason my screen will not power up?

    When I first connected mine, I followed the instructions and did "sudo apt-get upgrade", to upgrade my OS.  The display did not work.  I had to change to Rasputin-Jessie OS.  That worked.

     

    Recently, I had a bad micro SD card and had to format another with the OS.  Jessie has been replaced by Pixel.  It works with my touch screen.

    Custom metal enclosure.  Pi2 is mounted to back of the display.  The GPIO pins are extended to a DB25 and DB15 connector on top.

    I am working on putting a battery pack inside the case, making it self contained.

    Please excuse the messy work bench.

     

    Yes the display works great with Pixel.

    Nice Enclosure. The DB25 and DB15 are Nice Retro Touches.

    Like I said I use a SmartiPi Enclosure:

    Pic of my unit assembled. That is a Bitscope USB Oscilloscope mounted on a Lego Brick (i.e. detachable)image

    Pic of the back of the SmartiPi -opened-Up. Note that the HDMI Port is blocked

    Cutaway (using Dremel Tool) to expose the HDMI Port

    BTW the SmartiPi Enclosure Back Panel (Not Shown) has an Opening for attaching a 40pin Ribbon

    Cable to the GPIO Pins in the Photo above.

    The Touchscreen & the HDMI Port  (w/ HDMI Monitor) can be used CONCURRENTLY. Same as a USB

    Mouse and the Touchscreen Mouse, can be used CONCURRENTLY. I Didn't try using a USB Keyboard

    and the Touchscreen Keyboard at the Same Time Though. I didn't wan to push my Luck
