We often get queries about TV links not working. This is usually a very simple thing to fix, but clients get confused because they are not sure how to proceed through the process of elimination.
Snow is caused by
- RF signal from the DSTV decoder not reaching the TV.
- Remove the TV Link.
- Connect the RF cable from the decoder straight to the TV antenna in plug.
- using the TV remote, change the signal source on the TV to “TV”.
- using the TV remote, press the “menu” button and autotune the TV.
- Check P1, P2, P3 etc up to about P8 to see if the tuning has found your decoder signal.
If not, there is a problem with the connection from the decoder to the TV.
- Check the f-connector connecting to the “RF-Out” output of the decoder. If necessary re-seat the f-connector.
- Check the f-connector on the TV side of this same cable. If necessary re-seat this f-connector.
- Check the cable for joins, such as a barrel. You might have to be prepared to climb into your ceiling for this. If you find a barrel, replace it with a new one and re-seat the f-connectors on either side of it. Sometimes you might come across a splitter in the ceiling where your cable enters and leaves again. Most often it will be an “SLX Splitter” which are used to relay RF signals to TV Links. If this is the case, replace the SLX Splitter; most users at this point will probably be getting out of their depth so it will probably be best to call an accredited DSTV Installer. However, this is not often the case, so read on – the solution is usually a very simple one!
- Signal from the DSTV decoder reaching the TV but the TV not tuned in to the decoder “channel” frequency.
This is a very common problem. Some TVs will lose their tuning when powered off and on. So try autotuning the TV again as mentioned above.
- A faulty TV link This in turn has two parts to it:
- The electronic unit of the TV link is faulty
- The connector where the TV link plugs into the TV can be faulty. If one moves this plug where it fits into the TV antenna socket, and you see a fluctuating picture on the TV, this is a sign of a poor connection.
In either of these two cases, replace the TV Link and the problem will resolve.
Please note that this snow problem is a separate one from “My TV Link won’t allow me to change channels”, which we will address in a separate post.
