Lights are on but nobody is home!!!

Post by docbrownie5 » Sat Apr 03, 2021 5:19 pm

Hi All -

I've gotten a large amount of my soldering and wiring done on my GBZ project, but now I'm having what I hope is a small issue. When I plug in the power, the screen turns on, but nothing is coming up! I tested the pi zero W before and it seemed to work. I'm hoping that you all might have some advice regarding where I should go from here. Thanks in advance!!! Image is attached.

Double check all the soldered connections between the gpio of the pi and the DPI board. Some of them don't look great.

Also ensure you have a properly formatted SD card with an image that has the DPI drivers installed.

When connected to power do you see the LED on the pi at all?

Hi! So since I last posted I got a new board and tried it again. Again, I'm having the same issue. This time I skipped the pins and when by the method recommended here, https://www.tinkerboy.xyz/tinkerboy-dpi ... ader-pins/
The only differences are the updated DPI board and that I'm using a Pi Zero W. The screen turns on every which way I power it, but nothing seems to be transmitting. However, when I plug the HDMI in on the Pi, I see signs of life. Any suggestions?
