I just purchased 3 RPi3 boards from Pimorini. It powers up but will not boot - hangs at colors screen. No console is ever displayed.
- I have created multiple new OS installs on new SD card (Type 10) - No luck
- I have used existing good SD cards with OS on them - Tested on Pi2 just before running on Pi3 - No Luck.
- I have changed power supply - Using one that has just successfully powered several other Pi2 units - No Luck
- The SD card holder type seems to have been changed from the spring lock type to simple slide. I might think it was faulty card holder but I have three brand new Pi3s and they all have the same problem.
This should be a no-brainer but so far I am not sure that the Pi3 is the success I have hoped it would be. Any thoughts will be greatly appreciated.
