All HDMI inputs have stopped working on my TCL 50 tv

It didn't happen all at once but over the past week the 4 HDMI ports on my 50" TCL Roku tv have stopped working and I'm not sure what exactly may be causing this issue. The TCL model number is # 50S...

    Hi Dfresh567,

    Thank you for posting here in the Roku Community!

    We get that your Roku TV HDMI port is not detecting the device that you are connecting to. We're here to assist you with this.

    Before we proceed, we would like to know what external device you connected to your Roku TV and what error you are getting.

    In the meantime let's see if this will work for you.

    • Switch the HDMI cord to a different HDMI port. (Example: From HDMI 1 to HDMI 2 or 3)
    • Firmly plugged in the HDMI cord to the HDMI port.
    • Try connecting your external device to a different television and see if the same issue occurs.

    We look forward to hearing from you soon.

    Thanks,
    John

    I've gone pretty crazy with making sure i try each HDMI port and triple checking to make sure they are firmly plugged in. I had a retro upscaler which i was using to play my SNES which I thought was broken and was able to return it cause one day it stopped working and figure it was that was the issues,

    After that my Nintendo switch hmdi port stopped working and my apply TV hdmi port I can't really tell which came first but now I've tried my apple TV which is the newest version in every HDMI port. I'm done the same with my switch. I'm tried different HDMI cords you name it.

    One thing i have yet to try is unplugging the TV or if there is a hard reset for the TCL that cause have a postive effect on the HDMI ports. I've had the TV for a handful of year

    Thanks for responding and trying to help!

      What was the fix for this?

       

      ((Fixed))! Inexplicably unplugging the TV and waiting a minute, then plugging it back in and then all my HDMI PORTS are working again.

        Try unplugging your HDMI cables out of the TV as well as unplugging the power on your TV for 60 seconds.  Then plug the power back on the TV and reconnecting the HDMI cables.  Make sure they are firmly in place.  Sometimes HDMI ports have to resync and don't always reconnect when something gets out of order, especially older versions of the HDMI specs.  If that doesn't work, you can try new HDMI cables (make sure you get 2.1 or later and certified) and try that.  If those suggestions don't work, you might want to reach out to TCL tech support directly and see if they can help.  Unfortunately, most of the budget level TVs don't use good quality or long-lasting components and it is possible the control board for the HDMI has failed or the ports or cables have been damaged.  You can check to see if any pins are bent on the cables or ports and try to straighten them as another option.
