I have a Q80D and I'm having a hard time with the fire stick. It's showing up on my screen, but when I click on it I can only watch it for a few minutes and then the screen goes black and it says check device power. At first it would do that and then automatically come on itself, but now it's just stuck on the check device power screen. I tried plugging it into a different HDMI port and it does the same thing. It's a new fire stick and I used it with my older TV for a couple of months with no issues.
Is it only the Fire Stick you are having problems with? Try this, turn off TV, unplug from power. Unplug all HDMI cables, wait 20 minutes. Plug TV back into power, plug devices back into HDMI ports.
Thank you! I'll try that if I continue to have an issue. I just tried turning off the HDMI CEC, as well as reducing the screen resolution to my fire stick. Fingers crossed
I believe I found the solution. I tried what Robin suggested ,and I also turned off the screensaver on my fire stick, as I read from another article that could be an issue. Seems to be working now. The only thing I notice is that on the home screen of my TV, instead of saying Amazon Fire stick, which is what it said when I first set up the tv, it just says HDM1. I can live with that
