I own Nebula Mars 2, and i have an issue with it now. The HDMI port was working as expected, and all of a sudden there is no video output and I have only audio output. The last I connected was my laptop, and the Next day when I try to connect my gaming console, it gives only audio output, and no display output.
I then tried to connect my laptop back, and its the same result, no display.
I tried to change the HDMI cable as well, but no luck.
