![]() It might seem silly, but it's a fairly common reason why the No HDMI Signal error might appear. It's also worth checking if the source device is connected to power. If it's not working, it might be an issue with the device's HDMI port or the HDMI cable. If another device is successfully connected to your TV over HDMI, unplug it and plug the new device into the same port. Plug the device into the different HDMI ports on the TV and try each one. If this doesn't work, the next step is making sure the HDMI port is working properly. Switch to the correct HDMI input, and the signal problem should be resolved. To change the input, check your TV remote (not the one that comes with your Fire TV Stick, Roku, or Apple TV) and look for the 'Input' button (usually denoted by a box with an arrow).

This could be due to a faulty HDMI port, a faulty HDMI cable, a projector malfunction, a computer malfunction, or the computer being turned off. So, if you turned on the display before your HDMI source, try turning both off and then powering them on in the opposite order. If that doesn't work, the next thing to consider is changing the boot sequence. It's an underwhelming troubleshooting method, but it forces lots of important processes to restart and often results in a successful handshake. For this reason, the primary solution - and the first thing you should always try - is to simply unplug the HDMI cable from the source device, wait for one minute, and plug it back in. Almost all of them are simply various ways of making the two devices attempt the handshake again. ![]() In those cases where the handshake doesn't play out how it should, and you're certain there isn't just a loose cable, there are multiple, simple solutions to the problem.
