Pocket-Lint Recommendations: Fire TV Stick.The Sony's Chromecast is powered by an external power strip, which is why that Chromecast can turn the TV on when you select it. The 2 on the Samsungs are powered (when the TV is on) by a USB connection in the TVs themselves. 'All the Chromecasts connect to the TVs via HDMI, but are powered by USB. I'll make some switches later and see if that works. I think all the other HDMI slots on the main tv are occupied so I can't test the HDMI theory just yet. I haven't tried any of my other Chromecast-compatible apps. It just doesn't appear in Hulu, Netflix, Google Photos, or Youtube. Again, it also shows up in the Google Home app. I meant to also say that the main Chromecast screen DOES show up on the tv with my preferred background settings. I'm wondering if this is where the issue is. On our bedroom tv, it is connected via HDMI. The device on our main tv is plugged in via the USB. We powered the tv off/on several times and my husband, a audio/video professional doesn't think the tv would be the issue anyway. I hesitate to say 'device' because we tried to different devices on the main network -the tv in our living room. Meanwhile, the network on my phone switched from my FIOS network to the Chromecast network from the device in the bedroom which is the network that is working. It's hard to remember those names but it seemed familiar. I think it might be trying to connect to the network name we had before we got a new router several years ago. Now, when we re-booted the router, the device on the problem area tv kept trying to connect to the wrong Wi-Fi network. It also happens on my laptop running Chrome. We know it is not a phone issue because it happens on my husband's phone as well as mine. All three show up in Google Home as active and ready to cast but the main room device does not show up in any of the regular streaming apps we use. We have 3 Chromecast devices in our house. DOn't really feel like typing it all out again but Im frustrated as hell and I have yet to find a fix. You would think there would be a save mode when that happens.

I just wrote a long comment and when it went to make me sign in I lost it.
