Hi there! You are my last hope. Trouble: when turn on Zidoo X9S everytyhing seems ok(first goes "Boot" then "Hello" and "Time"). Box connected by HDMI. Tv shows message "HDMI no signal"(i tried several TVs, on one was black screen for severak secs and again this msg). If i use AV input everything is ok. But TV resolution is 4K and quality is bad. I change resolution, do hard reset and flash firmware to 1.4.12 but nothing helped. Still "no signal". Please help me. PSrevious owner use it it with projector and everything was ok! Sorry for my English.
Try using a brand new cerified 4k high bandwith hdmi 2.0 cable And a name Quality name brand or borrow one to test out .
