Use The HDMI Cable Test Function
Did you know that some TVs have a built-in HDMI Cable Test function that can help you diagnose any issues with your HDMI cable? It’s a handy feature, but it might not be available on all TV models. Try it to see if you have a faulty HDMI cable.

Try Replacing The HDMI Cable
If unplugging and plugging back in your HDMI cable doesn’t do the trick, it might be time to swap it out with a new one. Try using a compatible and certified HDMI cable with your device for the best results. Using a non-certified cable may cause issues with connectivity, and we don’t want that! So, grab a new cable, plug it in, and see if that fixes the problem.
Try Connecting Another Device
If you are having trouble getting your TV to display properly, a few different things could be the cause. Say your TV works fine when other devices are connected but experiencing issues with a specific external device. The external device itself may be causing the problem. We suggest contacting the device manufacturer and requesting a repair or replacement.
