The HDMI standard transmits picture and sound to your screen or television at the same time - with just a single cable. As a rule, this transfer also succeeds without any problems. But what if you get the error message that no signal is arriving at the device? We have summarized the most important causes and solutions for this problem for you.
No signal on HDMI cable - you can do that
Checking the connections
First of all, you should check on the receiver and also on the TV whether all plugs are connected correctly and are securely in place. Sometimes that solves the problem. In order to rule out a loose connection due to a damaged plug or a defective HDMI socket, you should carefully wiggle the plug and check whether you can establish such a connection.
Setting HDMI as input
source In order to be able to produce a picture, HDMI must be selected as the source on the output device or on the TV. You can usually select the signal source with the " Source " button on the remote control and then have the option of switching between HDMI and other signal sources..
Most common TV remote controls have a "Source" button to select the signal source. Checking the Cable for Damage
If you still cannot connect, inspect the HDMI cable for damage. For example, if the cable is jammed in one place or has other damage, a cable break may have occurred. In this case, you should replace the cable.
Check whether there is any damage to the HDMI cable. Using the latest driver software
When using the device on a PC as well as on a TV, you should ensure that your device has downloaded and installed the latest driver software. Again, this can be a cause of the HDMI connection not working. If you are using a PC, you should download the latest driver software for your graphics card. You should check in the device settings on the television whether the software is up-to-date. An automatic update of the driver software is often available on the TV; you should activate this if possible..
Ruling out invisible damage
Even without visible damage, the HDMI cable may be defective. To rule this out, you can connect the HDMI cable to another device. If the connection works here, the cable is OK.
If none of these tips worked, it is very likely that the cable is defective. In this case you should exchange the cable for a new one.
