Recently my TV has stopped receiving video via HDMI. I have a Roku connected to a Denon Receiver (the receiver handle the device switching) and one HDMI cable that goes OUT from the receiver to the Samsung One Connect box. So far I have... Swapped HDMI cables. Swapped Inputs. Reset the Receiver. At this point I can do nothing else. I can be watching the Roku and the TV just goes black and the "no input" error pops up. But I can still hear audio. After doing any number of the three things above, the video comes back. But only temporarily. It eventually goes black again. While this is an issue, one other thing I noticed was that I have a light strip (that runs behind the TV for ambient lighting) connected to the USB port on the One Connect box. This light strip recently went out. After a few days , the TV went black again and I started unplugging and replugging cables and I unplugged and replugged the One Connect cable. The TV "rebooted" and the picture came back as well as the light strip. This seems to indicate an issue with the One Connect box. I realize this is a 2017 TV, but surely it should last longer than this.
