Solve the problem of interruption of the signal from the receiver

When you return home after a hard day, you are definitely looking to relax in front of the TV to watch your interesting series, but the phrase No Signal appears . This is the solution to the problem of signal interruption from the receiver. Make your own satellite TV, and we hope to help you get it working again.

Necessary tools and materials

• receiver
• LNB cable.
• pliers.
• Signal tuning device.
• sharp scalpel;
• Rubber adhesive.
• Satellite dish.
• links.
• cables.

Solve the problem of the signal interruption on the receiver No Signal

1- Check the cables that are not connected correctly

We start solving the problem of the signal interruption from the receiver No Signal with the problem that occurs when the cables are too short, which leads to them swinging in place inside the receiver, which leads to a sudden interruption of the signal, complete loss of the signal, and a lack of good contact with the main plug body on the receiver To solve this problem, do the following.

• First, unplug the receiver and the TV from the mains.
• Remove the LNB cable from the receiver by rotating its metal head counterclockwise.
• Look at the copper tip, as it may be too short, or become bent due to the shortness of the cable.
• Try to make the cable longer either by changing the location of the receiver so that it is closer to the cable, or find that any extra length of the cable is outside the house, and pull it inside.
• Remove the old rubber adhesive on the cable head, and remove the metal head.
• Using a serious scalpel, cut the cable from the front if the copper tip is bent, or too short.
• The length of the copper head should be about 1 cm, to ensure the best contact with the socket of the receiver .
• Return the metal head and secure it well with electrical tape.
• Then connect it to the receiver and check the network again.

2- Breakage or bending of the satellite dish

Satellite signals are transmitted to satellites in space and are reflected on a round or oval part of the satellite dish, and then to the LNB cable that transmits the signals to the receiver. If the round part of the dish is distorted or rusted , this can cause the satellite signals to bounce Industrial at different angles.

Make sure that no one has tampered with your satellite dish, and physically inspect it for any dents or widespread rust. If there are such problems, the dish should be replaced immediately.

3- Heavy rain and thunderstorms

Since the satellite signal is emitted from the Earth by satellites in space, the atmosphere and weather conditions can affect the reception of satellites , especially heavy rain, clouds, and thunderstorms, because satellite waves travel through these layers, and the water is an electrical conductor. This causes the signal to stop temporarily while the storm subsides.

4- The dish is not connected to satellites

The satellite dishes must be aligned very precisely to get a signal, because of the way they work, and the frequencies the channels use, it is not easy to align the satellite dish by sight alone, or by looking at the direction of the neighboring satellite dish, one millimeter tuning can be It is the difference between a good satellite signal and no signal at all.

If you are going to try to reset your satellite if it has been shifted from its direction, or you think that this is the reason why the signal from the receiver is interrupted. It should be noted that you need to correct this on three directions, east, west, elevation, and skew adjustment on the LNB itself. If you are going to try it yourself, you should bring a TV Spectrum Analyzer, where you can see on its small screen numbers that you have reached the strongest signal.

If you are looking to solve the problem of signal interruption on the receiver, No Signal, and you are a fan of repairing things with your own hands, you should buy satellite tuning tools that are available at reasonable prices.

5- Ensure that there are no obstacles in front of the satellite dish

It is possible that after installing the satellite dish, a nearby tree has grown, and this tree constitutes an obstacle to sending and receiving signals to the satellites in space. The satellite is to a higher altitude, but the connecting cables must also be long enough to reach the top.

If the problem still persists even if you raised the dish to the top, the trees may still block the signal, you can consider raising it more than that, or installing on a wall away from obstacles whatever they are, or installing it on a pole overlooking the roof, or the building so that it does not block The building itself is referenced.

6- Cables exposed to water

Since the satellite dishes must be installed outside, and because the cables need to be connected externally to the receiver, they are likely to become exposed to rain, so appropriate measures must be taken to prevent rainwater from entering the cable, there are several ways in which this can be done, but as Here are some of the most common methods.

• First check the watertight cap on the LNB if it has become worn out and cannot be relied upon to prevent water from seeping into the cable.
• Use of F-type pressure seals that can withstand water pressure, are ideal but are expensive, and require a specialized tool to attach to the cable.
• Using silicon to cover the connections on the LNB cable, silicon is a satellite's best friend, as it can be distributed over the top of the sockets to protect them from the elements, because the outside of the components remains completely dry.
• If the satellite signal does not work, and you notice that the connectors themselves are submerged, you may need to cut a portion of the cable, and reconnect it using the cable connectors, but if the inside of the cable gets too wet it may be best to replace the cable completely.

7- Malfunction of the LNB cable

It is possible that the LNB itself is faulty, LNB errors can be responsible for a lot of problems, where the satellite signal becomes good for long periods, then suddenly stops and the message No signal appears.

It can be difficult to diagnose this type of defect, even with expensive test equipment, but if you are sure that the dish is installed and oriented correctly, and you notice a sudden signal cut and then return after a while, you should replace the LNB cable with a new one.
