SS IPTV

Hello, I just bought new HISENSE H50A6140 and I updated TV and decided to install SS IPTV on it via VIDAA U app store, I successfuly added my IPTV channels but it wont play any channel, black screen, no sound..I use the same channel list for KODI and VLC on desktop and everything works on it, but on TV it just wont work, I don't know why..there is one channel from my list for example:

#EXTINF:0,HRT 1

Is something wrong with formatting or ?
Anyone had same problem?
