I understand how this may be frustrating and want to help, have you tried the following?
Newer TVs will automatically detect a device once it is connected via HDMI. If your TV was manufactured in 2017 or later, you should be able to skip step 2.
Press the power button on the connected device.
Verify that the connected device is actually powered on. If it doesn't turn on, then you need to contact the manufacturer of your external device.
Select the correct source on your TV.
When your device is connected to your TV, you have to set the source on the TV to the same port you connected your device to. For example, if you connected your Xbox to the port labeled HDMI 1 on the back of your TV, then you need to set your TV's source to HDMI 1.
Disconnect and reconnect the HDMI cable.
Disconnect the HDMI cable from the back of the TV and the external device. Then reconnect it firmly to the external device first, then connect it to your TV.
If it still doesn't work, try the cable in a different port. Don't forget to select the new source.
- If it works in a different port, your external device and HDMI cable work, but there seems to be an issue with the original HDMI port and you need to schedule repair.
- If it doesn't work, continue troubleshooting.
Try a different HDMI cable.
Use a different HDMI cable to connect your external device to the TV.
Connect a different external device to see if it works.
- If the new device works, the issue is with the original device. Contact the manufacturer of the original device for further assistance.
- If both devices do not work, and all other steps have been completed, the TV requires service.
If the troubleshooting steps did not help above then you have a couple of options based on your warranty.
- If your unit was recently purchased, you can check with your retailer on their return/exchange processes.
- If you have an extended warranty you can reach out to them to have service set up.
- If you're within the one year warranty, you can Private message me or one of our moderators with your full model and serial number to have service setup
- If you're OUT of warranty, you can use this link below to find a service center in your area.
