It’s been a while since I last open UnifiTV on my Mecool KM3 tv box, everything works fine for the app. Audio and subtitles are there, but I have no visual of the video played.
It’s a blackscreen with just subtitled.
So, I uninstalled the modified version, and get the official version frkm Playstore. Login in fine as well, but still the same issue as above. Channel can be played with audio and subtitle, but no video.
Has anyone face this issue before? It seems rather weird to me, as I can see subtitles but not the video at all.

Ah I see. Not sure how do I fix this or what may had caused it.

Turns out that it was the HDMI cable issue. It's pretty weird though. I can watch netflix but not unifitv.
Either way, it was fixed! Thank you!
