So far not a happy customer

[pine.tree]

Received my Pine64+ today. Been playing with it for 3hrs now.  All I get is a black screen, tried it on a monitor with HDMI-DVI and a TV. Nothing

Have tried 3 versions of the Android Lollipop and remix os. Been using a class 10 SD card and power cable from my Ras PI. Get the red light, but nothing else..

Think I should have gone with the PI 3, I'm sure I noticed my network cable light flickering earlier but then nothing..

Have left it for 10mins even 30 mins after a clean install..

Any other ideas guys..  

Is there any signal coming into the TV? If not, try another power cable. Make sure it's at least 2A, and the thicker the cable the better. Quick advice, i would use trial and error to see if changing cables and adapters does anything. That seems to be the main problem with Pine64's, certain cables don't work. 
How are you installing the OS's onto the card? There's a whole thread for just sd card burning software, some people had to use a different program to do it to work properly. Sorry you're having issues, i'm sure it'll work out soon enough
