I have a Kingbox K3 (S912) 2/16GB Wi-Fi HS2734A
I have tried several slimbox and M96X ATV plus 4chip ram, when using USB tool to install successfully,
When i plug it in, i cannot display the image.
Light source on, optical port indicator on, but not outputting HDMI and AV signals.
Please give me advice or ask for some ROM for this box.
