Try a different HDMI cable. See if that works first. Sometimes the HDMI cables are poor quality and will cause loss of signal and TV will shut off or appear to shut off. Also double check the plug and coaxial cable coming into the satellite TV or cable box. Make sure there is good connection. If all plugs are nice and tight and cords are good then next try starting TV and downloading the latest firmware. If firmware is outdated it can cause issues. Have to go to Smart Hub or settings to do this on TV. Might take a few tries if keeps cutting off. Also make sure using surge protector to plug in TV to prevent power fluctuations. If none of this works need to use Samsung 1 year warranty service and have them replace the TV or repair it.
