I am powering from a known good phone charger, with a mini-SD with recent version NOOBS and connected to a known good LG screen via mini-HDMI adapter and HDMI cable. The HDMI cable is known good, the mini-HDMI I do not know.
On power-up the PZW AC LED flashes a few time, blinks then settles quickly into a steady green. Nothing appears on the screen at all - it seems to indicate that it is not connected to anything
Troubleshooting so far :
All the above leads me to conclude :
- something wrong with the mini-HDMI adaptor ? (Any way to test this without a known good mini-HDMI output ?)
- Something wrong with the mini-HDMI output of the PZW
- Something in the NOOBS software image that works well on the older Pi but not on the PZW
Pi Hut, who supplied the device and accessories have offered to do a return. But I am just interested to know of any other trouble-shooting ideas that can be done quickly, saving the hassle of return (e.g. if it is just the mini-HDMI adaptor then that is easier to send back than the PZW).
