I have a Raspberry Pi 4 4gb with a 3.5" Kuman LCD touch screen. I am running a Raspiblitz Lightning node on the setup and just received a Fan Shim to install on it. For some reason, with both the Fan Shim and LCD screen installed, the system will not boot. The LCD will turn on along with the fan and randomly display code without proceeding anywhere. Ends up stopping on a blank screen with a little dash in the top left corner.
If I remove the LCD and keep the fan installed, the system will boot and operate as normal. If I remove the fan and install the LCD, the system boots and operates as normal. With them both installed, no luck. Any ideas which part could be causing the issue? Power supply is the Cana Kit 5.1v, 3.5A
