You are watching your favorite series and out of nowhere your TV quits the service. At least it seems that way at first glance - but your TV continues to play the sound. A defective TV set is not always responsible for this. In order to rule out possible sources of error, we will show you what the cause could be.

Black screen - you can do that

Probably the simplest reason why you get no picture and still get sound could be a defective HDMI cable . If the signal is disturbed here, the picture on the television remains black. So, take a working HDMI cable off another device and test again on your TV.

On the other hand, loose cable connections between the television and the DVD player, TV box or other additional devices can also be responsible for this. Therefore, carefully check all cables that are connected to the device..

Carefully check the power supply and connections. The trivial answer to your problem - before you panic - can also be defective connections. To do this, proceed as follows:

  • Turn off your TV and unplug it.
  • After 15 minutes, plug the TV back in and press and hold the power button for a few seconds.
  • Release the button and turn on the device.
  • If the image is transmitted from a cable box or other device, you may want to replace that device or try a game console.
  • Go to the settings menu of your TV and check the settings here.

If you cannot call up the menu either and the screen remains completely black, there is probably a defect on the TV. Common causes are defects in the power supply board or other internal hardware. If you can rule out that defective cables such as HDMI are responsible for the problem, you should check whether the television is still covered by the two-year warranty. Apply for a repair from the manufacturer, stating that the sound works, but the screen remains black. Otherwise, you only have the option of repairing the TV yourself or contacting a specialist. Here, however, you have to estimate whether the additional costs are worthwhile compared to buying a new one.
