Having no signal on certain DStv channels is one of the most common problems that DStv subscribers experience. This error is caused by either poor signal strength or quality below 50%.
So, generally, your decoder will display a “DStv signal error” on other channels that require a strong signal. Since your satellite dish is not completely out of alignment, channels that require low signal strength will be playing with no problem.
In this post, I will explain the reason why your decoder is not having the signal on certain channels. Also, I will tell you what you can do to restore signal back on all DStv channels.

What causes some channels not to work on DStv?
As I have said earlier, poor signal strength or quality is the main reason why some DStv channels are not working on your decoder. In most cases, it is the misaligned satellite dish that causes the problem. Remember, an LNB that is out of alignment can also cause this problem.
Poor DStv signal causes problems on other channels
If your signal strength or quality is below 50% then you are more likely to experience this error. Your DStv signal consists of horizontal and vertical channels. To add to that, some channels do not require a strong signal strength to play. These are the channels that play even when your signal strength and quality is low.
On the contrary, other channels need a very strong signal strength and quality. So, when the signal strength goes below 50% your decoder will start displaying signal problems.
If you have a DStv extra view set up then there is a simple way to find out if the problem is being caused by poor signal strength and quality. All you need to do is to find out whether all the decoders are experiencing that same problem. Remember, all decoders in an extra view set up watch the same channels.
What to do when some DStv channels are not working
The only thing that you need to do to solve this problem is to improve your signal strength and quality. Follow these steps:
- First, check the DStv signal strength and quality.
You can do this by pressing the “Help” button on your remote control and choosing “General Information“. You can then select “Information Central” to see the values of strength and quality. If the values are below 50% then you have a problem.
- Check the condition of the F-connectors on the signal cable.
Faulty connectors reduce DStv signal strength and quality. So, fix them if they are the problem. Here is a link to my video on how to connect an F-connector on a DStv coaxial cable: https://youtu.be/s27OXw8t0L8
- Check for joints along the DStv signal cable that are not properly connected.
- Check the alignment of the LNB.
Align your LNB at an angle relative to the satellite dish. It should not be facing down.
- Align your satellite dish properly.
You will need a satellite digital meter to do this task in order to get the best results.
