Hi, suddently my U9H sems refuses to power up, I mean if I press the power button the blue light led quicky blinks but don't stay lit. There is no video signal at all. Tried to factory reset (pin hole on the bottom), alse keep pressing the power button for many seconds but no change.
Quicky reading here, seems that it might be a problem with the power adapter ? I don't have yet and 5V adapter to check it, but I can try buy one if the symptoms I described suggest that this might be the problem.
Any other advice ?
Thank you !a

Tried with another cable/monitor, same. The problem is that the power blue light don't stay lit, and as far as I remember, it should stay lit.

So the problem is power. Replace power adapter.

Partially solved with a new power adapter, but after short time I suddently loose HDMI signal (the power led stays on) and I have to unplug the power and power it again.
I guess that the power supplied is not enough ? It's rated for 22W/1A max, I ordered a 5V / 3A universal adapter, hope this is the culprit.
But not sure about the tip, it is 5.5 x 2.5 mm ?
 
Yeah . You have right. Needs more A.

MINIX NEO U9-H needs a 5V/3A power adapter. Your power adapter has a maximum output of 1A, and the current is not enough to drive the device.
The 5V/3A power adapter can be purchased from Amazon.

Thanks, it's kinda of hard to order from US (being in Europe), but I've ordered this one, hope it's okay.

I've got the one I've put in the link above, and finally my Minix seems to rock stable, runs Kodi since last night and no freeze, no HDMI signal lost :cool:!

That's good, but I wouldn't trust an adjustable PSU like this to be permanently connected to my device. If the voltage switch failed and the device receives a higher voltage it may kill the device.
