I’ve just ordered a Pi Zero W, but it’s completely non-responsive.
I have a few Zero’s and a couple of Zero W’s already, so I’ve used 2 Zero’s and 2 Zero W’s to troubleshoot.
- Each power cable works with each Pi.
- Each SD works with each of the working Pi’s
- Each working Pi’s activity LED works
- Each working Pi shows on the TV (2 mini-HDMI adaptors plus mini-HDMI lead)
In retrospect, I should have tested it before attaching the headers, but I’ve never had any Pi fail, Zero or otherwise. The headers were attached in the same way I’ve done in the past. I’ve attached photos for reference in case I’ve damaged it somehow.
My multitester shows there’s current to the GPIO pins on the new Pi. Both 5V and 3.3V have been tested against each ground pin in turn.
At this point I’m looking for suggestions.
