NFPS / Private audio and picture way off

IPTV Private Server (NFPS)
The reset did not sync audio and video. It seemed to work for a bit then changed channels and no luck. Something else I can try?

try to connect different hdmi cable if you have one as well try to connect on different hdmi port behind tv. make sure to turn you box and tv off before you connect them. after connecting cable turn tv on first then your box and lets see what happened. I dont know if this will fix your problem but you have nothing to loose here. unless problem is with app it self thats different story. kof
