For those with full digital AVR's you'll notice after 4-6 months with the Samsung Smart TV (possibly all smart TVs)hooked to it the TV might flash black screen for 1-5 seconds and do it quite frequently, if you have a AVR that has a auto calibration feature in the setting use the calibration mic it came with plug it up and recalibrate your speakers this fixed it for me but after about 4 to 6 months it does it again and I just recalibrate the speakers and it fixes it again. This Auto recalibration will also fixed the sound level with your speakers you may have trouble hearing the words but when you recalibrate it it fixes that too.
