We have already written several times about how to best connect a home cinema system and in most cases an HDMI cable is the best solution. Still, it can happen that after connecting equipment via HDMI you encounter problems such as no image or no audio. In this article, we’ll provide some easy ways to find out if you face No picture or audio via HDMI.
No picture or audio via HDMI
Two devices that are linked with HDMI must be able to communicate with each other and use a copy protection called HDCP. The fact that both devices can see each other and communicate with each other is also called the ‘HDMI handshake’. If this does not work (correctly), it can cause that no image is forwarded and displayed. With the suggestions below you can investigate the cause of the problems like No picture or audio via HDMI.
Check the connections if No picture or audio via HDMI
It sounds very obvious but check that everything is connected correctly. It may just be that you have used the wrong input or output and if this is not the case, a connector may be bent or a cable may have become loose due to moving equipment.
Check the cables
It is a misconception that an HDMI cable of 100 euros gives a better picture than a cable of 10 euros. An HDMI cable works or it doesn’t work, it’s that simple. If you have tried everything but still do not get a picture through your HDMI cable , it may sometimes be that another (cheap) cable works. So it pays to try at least two cables before giving up.
Check the settings
Before you can enjoy your newly connected home cinema system, it is important to check whether the correct settings are used for HDMI. For example, is the video resolution set correctly (can the display handle this resolution?), And is the correct input assigned to the correct connection on your home cinema set or receiver? It is also possible that the source is set to only pass audio or only video via HDMI.
Turning on equipment
Sometimes it may be the case that all equipment is correctly connected and that all settings are correct, but you still do not get a picture. This is usually the case when an HDMI signal is sent through, for example, a receiver or home cinema set. One of the reasons for this may be the sequence of switching on equipment. It can therefore help to switch on your home cinema system in different sequences and see if an image appears. For example, first switch on the Blu-ray player, then the receiver and then the TV. If you have a receiver or home cinema set with multiple inputs, switching to a different input and back can sometimes also ensure a correct ‘handshake’.
If the above ways still don’t answer the question of where the problem is, try simplifying the process of sending the image to the TV. Do you use a receiver, home cinema set or soundbar that is located between the source and the TV? Then disconnect it and connect the source directly to the TV? If you do get an image, then you know that the problem is with the receiver, home cinema set or soundbar. What you can do now is connect the source directly to the TV and lay a separate (digital) audio cable towards the receiver, home cinema set or soundbar. This is not an optimal solution because HD audio formats are not supported now, but at least you have image and sound.
Because the ‘HDMI handshake’ can be affected by the software on one of the connected devices, it is wise to immediately check whether there are firmware updates for your TV, Blu-ray player, home cinema set and receiver, for example. This update may bring newer software that enables a correct ‘handshake’. Read more about firmware updates in your home cinema system .
Still No picture or audio via HDMI? Contact the manufacturer
Unfortunately, you may still not get a picture after trying the above solutions. This could be due to a problem with the hardware or software. Search the Internet for users who have the same complaint, and perhaps they have found a solution. In addition, contact the manufacturer. They may take the device back to check and repair it.
