TCL 65S401 PC HDMI No Signal

TCL Model 65S401

Hardware ID 7113X

Software Version 12.5.5 build 4174-30

Problem: My TV will no longer display a PC connected to HDMI Port 2 only displaying 'No Signal (is it on?)'

Context: I have had this PC-to-TV connection functioning for over a year with no issues. I have checked everything in Windows 11 and Nvidia control panel. My PC detects the TV just fine. I have moved all of the ports around. The TV displays a chromecast on port 3 fine. I have factory reset the TV.

I took an LG tv and plugged it in to the same HDMI cable to rule out the cable and PC and the LG displayed the PC input immediately with no issues. So it is not a problem on the input side.

Reading historical issues with these kinds of TVs it certainly seems like a software update broke this input connection somehow which is really really frustrating. I have spent hours troubleshooting this issue from every angle and the only one I don't have control over is bad TV software that updates automatically.

    OP here, still have not been able to resolve this issue.

     

    Help from an official Roku support account would be appreciated.

     

    Is there a software patch planned to fix this problem?

      Thank you, goodshot.

      This is acknowledged and appreciated.

      However, we need one last detail which is a Tracker ID (when you see this issue occur, press the Home button 5 times, followed by the Back button 5 times, and provide us with this ID) as this will serve as your report tracker.

      We'll be looking forward to your update!

      Best regards,
      Carly

    Not sure if this issue is still and issue, but I am having similar problems connecting my 65S401 TCL Roku TV to my PC via HDMI. I will look at a movie, pause it, then--when I resume playing--the sound would be off. This has happened with a more than one video streaming app and a browser-based set of youtube.com videos. Each time, I have to turn the TV off and turn it back on...or...worst case...reset the TV despite it being updated. I hope a solution (i.e. software update) come soon.
