Yep, good firestick. I took it out of the house. The TV simply won't recognize any other input than the cable for OTA. Despite changing the input on the TV, it's just a blue screen. Even when I switch input to Cable whicle hooked up to CG cable, it scans and finds channels but wont let me actually change the channels. It's weird, it scans, says 100 channels found and then a blue screen. Maybe the TV itself is just garbage. It's the OEM Connexx brand which I have never heard of. I think it's a division of Furrion and my experience with their stuff has not been great.
So either the TV is just bad, or I am just not understanding something with how the input is being changed. But if I take a good firestick and plug it into an HDMI directly on the TV, logic tells me that despite any switch somewhere else, it should still recognize it.
