Roku Express 3200X suddenly says an incompatible video signal has been received
I bought this device in 2018 to use with my Sharp TV and it's worked fine. Now for some reason this morning I got the incompatible video signal error and nothing seems to fix it. I've unplugged the Roku and the TV, I've checked the HDMI cable in another device to confirm it is working. I can't test the Roku with another TV cause I only have the one. I'm stumped.
