Today I got a Raspberry Pi 3. When I powered it on for the first time I've putted on my SD Card the last image of Ubuntu Mate, but the red led was on and the green led was flickering and screen blank. So I decided to download Noobs Lite and when I turn on the Pi there's no green led and the red led is on and screen blank. I've formatted correctly and repeated all the steps twice to ensure to not have forgot something.
Can you please help?
UPDATE: My noobs SD Card which was previously 14,4gb, now has 120mb. I think something is working.
UPDATE 2: I've tried a different SD card and still the same problem. I've also tried to use a Power Bank 5V 3A but still nothing.
