I cannot turn off subtitles (closed captioning) for one of my three chromecast devices that are used to support my usage of YouTube TV and other apps such as Netflix on my TV. The subtitles are showing up regardless of which app is in use. I've tried everything in settings for both the apps and for the TVs themselves. I even bought a new TV, believing it was a fault of the TV. But, surprisingly, even the new TV continued to display the closed captioning. So next, I switched the chromecast devices between TVs. Lo and behold, the unwanted closed captioning followed the switched (faulty) chromecast device! So, it's clearly the one single chromecast device that is causing the closed captioning. There is no resolution I've found on any help sessions, searches, etc. I've seen other posts where a person has been frustrated in not getting resolution, but I've now done sufficient experimentation to isolate the only remaining possible issue. It is not a TV nor app setting as I've verified I can watch TV without closed captioning on any two of my three TVs that are not using the (faulty) chromecast device without changing any other settings. I now believe it is a faulty chromecast device itself, but am willing to hear if there is some other resolution or means to fix my faulty chromecast device. If true, how do I get a replacement?
