Why does my TV say no signal when HDMI is plugged in?

Check the HDMI input you are using with your TV remote control. The input button on your TV remote control will cycle between the various input ports. Every device connected to your TV is linked to an input port on the rear or side of your television. If the wrong input is selected, the image will not appear on the TV screen and it will say NO SIGNAL. If your video equipment is connected to the HDMI 1 input, use the TV remote control to switch to that input. Also double check that the connected device is switched on.

Why does my TV say no input detected?

Check the back of the TV or where the HDMI cables are connected. Look at the various ports on the rear or the side of your television to see which one is connected to the device. You may need to simply move the HDMI cable into a different input port as the TV HDMI port may not be working. Make sure the HDMI cable is connected into the correct port. Make sure the TV and source device are both switched on, and you can also try unplugging the HDMI cable from both the TV and connected device and reconnect them. Don’t forget to select the new source or HDMI port if applicable.

Troubleshoot the issue with the following steps by performing a reset:

The HDMI cable may have a faulty or loose connection this reset will tell you if you have a problem…

  1. Remove power to the TV and all components.
  2. Disconnect the HDMI cable from the TV’s HDMI Input connection and the HDMI cable from the linked device’s HDMI Output connection.
  3. Reconnect the HDMI cable to the same port on the TV and connected device.
  4. Plug the power to the TV and the component back into power.
  5. Turn on the television and your connected device and give it some time to “see” each other. This should fix the issue and act as a basic reset.
  6. If you still have issues with the TV not seeing or recognizing the HDMI, try using a different HDMI input on your TV to see if the problem persists. This means using the same HDMI cable but plugging it into a different HDMI port on the TV.
  7. How do I know if the HDMI cable is broken or faulty?
  8. It’s possible the HDMI cable is broken and unable to work as needed. Use a new HDMI cable or one that you know works to see if this is the issue. Some cheaper or older HDMI cables can get twisted or pinched and stop working.
  9. Connect a different component using HDMI and see if that works.
  10. Connect a new device such as a Blu-Ray or Xbox with an HDMI cable to your TV, if it works then the issue is with the original device. The TV is not the issue and the problem is with the component.

  1. I Have a TCL TV and i have a roku and ps5 plugged into the tv… tv wrks fine everyday until lastnight, which carried on thill the next day..ive unplugged replugged the hdmi cords.. but No matter what we do, the tv keeps saying no signal. Not sure what else to do…what to do from here.

  2. We just bought a RCA to hdmi adaptor for our playstation 2 and google tv. All the cords and what not have been unplugged and replugged with all the different input ports. No matter what we do, the tv keeps saying no signal. Not sure in the adapter we bought was faulty or what to do from here.

  3. I’m pet sitting for a friend and their switch doc works, my switch works fine, the hdmi port is fine and I switched hdmi cords, but the TV isn’t recognizing the device as “turned on” for me when it is. Just saying that the power is off when I go to hdmi troubleshooting despite the light saying that it’s on, being on, on the actual device. This TV is not even a month old and has been working with this switch doc within the past week, and a month ago my switch worked fine with the same exact doc but with their old TV. Nothing seems broken at all but I can’t figure out why it isn’t registering it as turned on.

  4. My TV detects some tv players like Roku but not google Chromecast tv or mi stick, Sony blue ray doesn’t show up as well.
    When I stream Roku, YouTube, any one after 2 minutes goes back to home page keeps doing that every 2 min.
    It is a plasma tv with just 1 HDMI port.
    They work on all other tv but not the plasma.
    Don’t want to change my tv because picture is great and everything else is working and can’t afford an other tv right now.
