I have a Minix Neo X7 fails to boot up. I bought it new but have not used it for a couple of years after if failed. The power supply seems ok as a red light is blinking inside the box. But when I power on nothing happens. I tested the HDMI line to the screen, which was active when I plugged it into my PC, but not when I plug it back into the Minix. I have tried factory reset and same result nothing is live. It was a great when it worked and I would like to use it again. Any suggestions.
