Make sure the TV and source device are both turned on, then disconnect the HDMI cable from one of the devices and then connect it again. If your TV supports HDMI Enhanced Format, and the source supports 4K, turn on the HDMI Input Enhanced setting to receive high quality 4K signals from the source.
Why does my TV show no signal when HDMI is plugged in?
To fix the HDMI no signal problem, check for any loose connections or frayed wires. If the cable is not damaged, change the input source and enable the HDMI connection setting. In addition to this, I have also mentioned other solutions such as updating the chipset and graphics of the TV and performing a power cycle.
What does it mean when it says no HDMI signal from your device?
In most cases, you get no signal from the HDMI source due to weak physical connections. You may not have plugged the cable all the way in, or the connection has become loose over time or due to movements. Before doing anything software-related, unplug and plug the HDMI cable on both ends.
How do I fix my TV when it says no signal?
Check the cable connections between the TV and your video device or receiver. Change the channel or try a different input device or movie. The received signal may be weak. If your TV uses a cable or satellite box, you may need to contact your service provider for further assistance in improving the signal strength.
