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.
