I used the Android LCD image. Also in case it was the LCD pulling too much power for my power supply I detatched the LCD and tried both android image that isn't specfgically for the LCD screen and also the Debian image both showed the same although I didn't have a display connected to the HDMI. I assume the power light should still not go off even if you don't have a display connected...
No, you shouldn't need a battery, unless you want your pine64 to be mobile ;D
Since you also the debian nonLCD image, and the power light still went off, I suspect either the USB lead you're using is wimpy and the voltage is dropping too low, or the power supplies you're using just aren't up to the task. Unfortunately, most 5v power supplies are around 5v when not loaded, and at hte power supply. Add to that thin wires, and load them up, and the voltage can easily sag to v4.75 or lower, and things like the Pine64 and Raspberry pi get unhappy! Try and grab yourself a power supply like the one Mark recommended, or one of the ones Adafruit sells... And no, the power light certainly should go off if there's a valid image on the microSD, and enough power is provided, regardless of if you have a monitor connected or not.
So I got the power supply tried it - same result red light flashes on then goes off....
Anything else I can try?
Ok, maybe we need to rewind a bit, and check something more basic... how are you putting on the images on the microSD card? Maybe something is wrong with the microSD which is causing it to crash and poweroff?
Otherwise, what happens when you have absolutely nothing plugged into the pine64 (no keyboard, mouse, etc). You can even remove the microSD card. Does the red power light come on when you connect the power usb lead and stay on? I just realised with mine that if I remove the SD card, and power it up, it will power on, and is still 'on' a couple of minutes later... although absolutely nothing is happening. Which is different from your case as it won't stay on.
