    Maby the hdmi handshake between your tv and box isn't okay.

    Did you turn off hdmi-cec on box and tv?

    Do you use official hdmi cable?

    Did you try other hdmi port?

    Did you already tried latest update? And or beta update? 1339 code in software update? Please try first-->

    Did you tried a factory reset once?


    Please be more specific please.

    Maby other hdmi port is already fine. And it's not the power adapter.


    Let us know my friend. Goodday

    Tried all that still the same with factory reset

    Factory reset, other same power adapters, other hdmi cable and ports and still the problem exist?


    Do you have warrenty?


    Can you test it on a computer screen with hdmi connection and other tv?

    If it works on a computer screen and or other tv you can exclude the problem.
