Hello, my name is ***** ***** I'll assist you. I'm sorry you're having trouble with it.
I need additional info to troubleshoot the issue.

- Have you tried to unplug TV and Roku box power cords from wall outlet for 10 minutes to reset, connect another HDMI cable, replug power cords back in and check?
If not yet, can you try it now and reply back with the result?

Sorry to hear that, did you try another HDMI cable as requested in previous reply?

Customer: replied 1 year ago.
as stated in the beginning I did use another HDMI cable still no change, people are saying it the "tv notshakinghands with roku
Expert:  Shahid replied 1 year ago.

That's correct, it is HDMI handshake problem (communication data issue) and mostly it resolved if use high speed HDMI cable having version 1.4 or higher. Please get the HDMI cable from other TV that works fine with this Roku box and try that cable on this Toshiba TV.

If problem persist then I'm sorry it seems HDMI processor chip mounted on main board of Toshiba TV has got internal issue and causing the error message, replacement of main board in this TV will help to resolve the problem. If you are not comfortable working on it yourself then you may please use following link to get list of TV repair shops in area which will help to get repair quote...
I'm sorry there is no easy or quick fix for this problem and it is definitely hardware failure that needs defective board replacement to resolve the issue. I trust my input will help you out to make decision about this TV repair or invest that money on new replacement TV. Please feel free to respond if you have any additional questions.
