Sudden Errror (no code): “Unsupported Signal”. Check device output.
I bought 3 Roku Premier Plus devices in Feb-20 for my 3 TVs. One of them suddenly stopped working for no apparent reason. I have tried restarting, unplugging, changing the input port to HDMI2 and resetting the device but I get the same error. This is the same Sony Bravia TV that we have used since we bought the device.
Re: Sudden Errror (no code): “Unsupported Signal”. Check device output.
Additional note: When I turn on the device, it goes through the Roku Start up screen with the letters jumping but does not ever get to the Home Screen. The screen just eventually goes black and I get the above error message which is likely from my TV stating the device is not sending a recognizable signal.
I would be happy to look further into this issue for you.
Can you please send me a PM with the following information: -Roku device model -device serial number -device ID -device OS (all of these can be found in Settings > System > About) -what brand and model TV you are connecting the device
With this information I will be able to pass it along to the appropriate team to look into.
