Hi Danny, thank you.
Here's the info you asked for.
Can you please provide us the following information:
-Roku device model, 3910RW Roku Express +
serial number, Y9005H450897
device ID, C53915450897
and software OS/version , 10.5.0 Build 4201-51
Issue# ID 97-459-287
Noticed the issue on 11/14/21 after being away for the weekend. It was working fine on Thursday 11th.
The HDMI cable error notice only comes up on Amazon. Netflix is fine and the Roku and Tubi channels are fine as long as I haven't tried to play Amazon. After I try to play Amazon, neither Tubi or Roku start and the Roku system even went into a re-start cycle on its own.
