Thanks. Not 3-month free? Maybe I see incorrectly.
On your TV and soundbar issue. If you have already plugged in your S/PDIF cable to the TV, look at the other end without plugging into the soundbar, got red light? If no, make sure the TV setting sound output is set to digital optical out. Check for red light again. If no light, change to a new digital optical cable and repeat the steps. If still no red light means TV S/PDIF port got problem, call PRISM.
However, if the above steps got red light and you plug into your soundbar and no sound, check TV settings again and check if you select the correct input setting on your soundbar. No sound? If you have other input sources for your soundbar, try it. If got sound from other input sources, you have to test your soundbar with another S/PDIF out electronic device like computer or Hi-Fi system. If got sound, call PRISM.
HDMI? Don’t know. Either incompatible cable or device.
BTW, Samsung soundbar what model? Digital optical connection quite plug-and-play one.
