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). Most TVs have multiple HDMI ports, and even if the source device and TV are connected to the HDMI cable correctly, choosing a different input can result in the error. In many cases, the order in which these devices are powered on will dictate the success of the handshake.Īnother common reason why your TV might display the 'No HDMI Signal' error is because the wrong input is selected on the TV. This is an extremely common solution for people with HDMI sources connected to a home theater system or an audio/video receiver. 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.
