Hello everyone, I have a Pine64-db rev b i bought a while ago, i've never used it and it was sitting in the static bag , i now decide to use it with
octoprint for my 3d printer and i applied power and while the monitor get drive for a few seconds, it reverts to no signal present , only the power 
led is illuminate , the usb keyboard led flashes when power is applied but thats it..it sits there dead..nothing , can anyone help me how to proceed
from here.
you need a good power supply. probably 2amp. you would be best to have ethernet connected at 1st boot. if i remember you need a monitor that does 720p or 1080p. it can stall if you do not have ethernet. then just have kb/mouse. it takes a while for 1st boot. what you experience is a common experience. if it persists try powering it via the pins. the usb power socket is lame.

Thank you for the reply i'm currently using a 5V 2.5Amp psu , i had an hdmi->dvi adapter connected and the monitor got drive, i also switched to a TV set with hdmi
and the same thing..no display , just a drive signal and then back to no signal, i however didnt have the ethernet connected as i was hoping to use wifi.. i will try with this and report 
back.. thanks again.
as i recall the dvi-hdmi did not work except in a limited number of setups with a certain type of dvi-hdmi adapter, don't remember the details. also, tv sets were problematic for some reason. it's all here in the forum if you care to search, but a straight hdmi monitor with 720p or 1080p is best bet. this pine64 board can be a frustrating beast until you get to know the ins & outs. good luck.
Reporting back: so i connected the Ethernet and DVI->HDMI and behold she powers up..only to be faced with another error
but this is related to the image i downloaded i suspected , but i wanted to thank you for your guidance. i'll try another image
and see if i can get a terminal or desktop and work from there..i can now justify buying another board for my openHAB..
