We've been having this issue ever since we moved into our house a year ago. We have a 2017 55" 4K Sony Bravia. Out of nowhere, the PS4 (literally a Sony device) that's always been plugged in and never moved or unplugged showed "no signal". We tried to plug it into other HDMI ports but still "no signal". Other things worked, like the Xbox One or the Chromecast that was plugged in. We tried every HDMI cable in the house, but no luck. The PS4 worked on another TV so the console was not the problem. After talking to support, I reset the TV to factory settings and we were able to fix the issue but only temporarily. A few months later, the same problem occurred with our Chromecast. Same exact issue where it only stopped working on one TV's HDMI's. Usually resetting to factory settings fixes this but not this time. And even when we do fix this issue, it just repeats itself after a few weeks. On top of everything, the Bose soundbar we have attached via optical cable just stopped working. Lights are on so the soundbar itself is functioning, just not with the TV. This should NOT be happening on a TV that costs this much. We have a MUCH cheaper TLC 4K 55" and it never has such issues. I'd like to know who to talk to or call to see if the HDMI ports themselves are shot. It wouldn't explain why they work only sometimes. This is incredibly frustrating.
