I recently received a HyperPixel 4 w/touch. After booting a fresh image of Rpi OS, installing the software via script, shutting down, and attaching the screen, my SBCs will not boot with the screen attached. I have tested on a Rpi 4B as well as a Rpi Zero W. Both units exhibit the same behavior, with the added bonus of the Rpi 4B growing extremely hot and emitting a magic smoke smell after 10 seconds with both the HP4 and power connected. Both boards booted fine after detaching the HP4. Seems like a short within the component to me. Please let me know if there are some troubleshooting steps I’m missing or if I just received a defective unit.
