Hi,

I'm having some touble getting the screen to work, its just black, no backlight or anything. I already posted in this other thread viewtopic.php?f=44&t=8279&p=76861#p76861 but this may be the better place to get support with your board.

Thanks,
I think infinitLoop's response in that thread was spot on. If the board is getting power, you should at least get the backlight, making the screen white. Can you check for continuity between the 3v3 pad and the far side of the resistor (near the connector)? It should read as 10ohms of resistance. You can also check for continuity between the 8 GPIO pads on the Pi and the pads on the adapter.

So I managed to get the screen to come on and show the white backlight. I haven’t managed to get an image on it though.

Did you set up your SD card image to use fbcp or fbcp-ili9341? It'll stay a white screen until that's configured. It's usually easiest to do that while you still have access to the HDMI port, or if you have another Pi Zero you can set it up on that first. (or, you could even use the composite TV connector, but HDMI's easier)
