Display not working on the new Pi Zero 2

[Brent Fraser]

I've got two 3.5 inch displays. They work fine on a Pi Zero 1 and on a Pi 3B. But not on a Pi 2 W (the new quad core).

The install procedure works and doesn't report any errors, but on reboot the display just shows the back light.

Never mind. Looks like it was a bad solder joint on the Pi header. It works fine on my other Pi Zero 2.
