The channels on the digital set-top box disappeared, digital television freezes – what to do if there is no signal?

The TV in standard mode shows 20 digital channels, but it happens that even this small number suddenly disappears. Since the channels are free,
broadcast failure can be due to various factors, but most often these are problems in the program or in the device receiving the signal. Some issues can be dealt with on your own.

Digital TV does not show due to technological violations or technical work

In most cases, the factors for the disappearance of several channels on a digital set-top box are technological disturbances associated with signal reception. It also happens that the broadcast of digital television is interrupted due to technical work, which is a mandatory point for maintaining the functionality of the system. Before you figure out the problem or call the wizard, you should try to look for the missing channels yourself:

1. Go to the settings section on the TV.
2. Select “Auto settings” first, then “Auto search”. The system will try to find channels.
3. If there is no result, you should try searching manually. To do this, select the “Manual configuration” subsection, set the required parameters in it, after which the process starts.

How to set up a digital set-top box in manual mode is described in the following video (the only thing you need to do is find a plate with the frequencies and channel numbers of digital terrestrial television for your city or region on the Internet): https://youtu.be/hcioy_kAZYQ

After the first try, some but not all channels may be found. Then the process must be repeated until each disappeared channel appears.

If attempts are useless, then you will have to look for a more significant problem. A channel that disappeared from a digital set-top box could simply be closed. Then it is natural that it is not on the network. The channel could be encoded, but this situation can be corrected if desired: you need to purchase a SMART card from the provider. Other causes of digital signal reception disturbance and their elimination are given below.

Lost channels on a digital set-top box due to incorrect encoding of the DRE channel

Sometimes the factor in the disappearance of several channels on a digital set-top box is the erroneous encoding of the DRE channel. It appears when the set-top box is in a state disconnected from the network for a long time. You don’t need to configure anything: you just need to turn on the device and leave it running for a couple of hours. This time is enough to synchronize the work. The restored set-top box will start showing channels again.

No digital TV signal due to lack of digital tuner registration

One of the reasons for the disappearance of several channels at once is the lack of registration of the tuner. The presence of registration on the official website of the provider is checked. If it is not there, then you need to register the prefix: enter the identification number – the numbers on the back of the device case.

Termination of the subscription to the services provided by the provider

If the user has not paid for the use of digital television in a timely manner, then the broadcast is interrupted, and an indication appears on the screen that the channels are paid. The solution to the problem is obvious: you need to pay for the service, and paid channels will appear again. However, the paid status alert may also appear on the free channel, which should not be the case. In this case, you need to require an explanation from the provider. Perhaps the channels have moved from free to paid status.

The effect of bad weather on the antenna

Digital television often disappears or shows poorly due to adverse atmospheric phenomena. During thunderstorms, the signal is transmitted intermittently. Gusty wind adversely affects the operation
of the antenna , as a result of which the channels on the digital set-top box are completely or partially lost.

You don’t need to do anything: when the weather returns to normal, the channels will start functioning again. Pull the antenna, do not move it. After the end of the thunderstorm, it is worth checking whether the cable connecting the antenna and the set-top box is intact.

No digital television signal: why and what to do

The reasons for the fact that the message “No signal” pops up on the television screen can be various factors. To understand the problem, the user should proceed in stages:

1. Check the condition and stability of the connection of each wire . It happens that the antenna wires are torn, bent, oxidized. It is enough to clean the oxidized cable, and the damaged wires must be replaced. Even a slight bend in the cable can cause malfunction of the device.
2. Make sure that the operating menu of the set-top box is displayed on the screen . If not, then you need to check the RCA connectors. Often the outer plates are damaged on them, due to which the signal is interrupted.
3. Check out the digital TV coverage map . Some users buy a set-top box without knowing that digital communication has not yet been established in their area of ​​​​residence.

Incompatible software

In the GS-HD satellite receiver, you need to enter the menu, select the “Restore channel list” option. If software incompatibility is confirmed, then on the remote control you need to find the CHANNEL and TV / RADIO buttons. These buttons must be pressed simultaneously on the set-top box and the remote control, after which the STANDBY command must be selected on the remote control.

Antenna settings failure

Half of the channels may be lost if the antenna settings fail. Only a master can deal with this trouble, so you should call the provider’s office and request a reconfiguration. The connection between the cable and the antenna or set-top box is also weakened. It is necessary to check if the wire is well connected to the LNB IN connector.

Insufficient antenna power

Digital signal transmission in a particular region is carried out at the same frequency, that is, the channels are broadcast jointly. If several channels are missing, then the cause may be inappropriate antenna power. To check your guess, you need to take the remote control and double-click on the “i” icon. The antenna diagnostic process will start. Two bars will appear on the TV screen, showing the degree of power of the device. If the indicator is weak, then you need to move the antenna to get at least 50% power. So the signal will improve, the disappeared channels will start working. How to test the antenna signal, see the following video: https://youtu.be/R-IKTeVhGvc

If there is no “i” icon on the remote, then you need to look in the instructions for the name of the power diagnostic button. It must be, but under a different name.

When choosing an antenna in a store, you need to consider how far from the place of residence the television tower is located:

• if the distance is up to 2 km, then it is enough to buy a simple home antenna;
• if the distance reaches 30 km, then the device is purchased complete with a signal amplifier ;
• distance up to 70 km – requires an external antenna, supplemented by an amplifier.

The power of the amplifier must also be taken into account. You should not take a device that is too powerful – it may not improve, but weaken the signal.

to make an antenna for digital TV is described in our other article. Perhaps it will be useful to you.

The TV does not find digital channels due to damage to the set-top box

The prefix must be taken to a repair shop if:

• information about it is not shown on the TV, but the RCA connectors are definitely working;
• the configured device reboots itself;
• when searching for a channel, information about the quality of the received signal is not shown, but the antenna is tuned.

TV damage

If the TV does not turn on at all, then the problem may be serious, requiring costly repairs. But you should not rush to the service center – first you should try to correct the situation yourself. Perhaps the reason for the non-working state of the TV is not terrible. You need to act in stages:

1. Check if the cable is connected to the outlet and if there is electricity in the room . Children playing at home or pets may inadvertently disconnect the cord.
2. Make sure the batteries in the remote control are charged . Change them if necessary.
3. Check if the surface of the set-top box to which the remote control is pointed is not blocked by anything .
4. Check the operation of the remote control . On the TV turned off, a small light should be on, indicating that the equipment is working. If the light does not go out, but the TV cannot be turned on, then the remote control is faulty.
5. Make sure the equipment is working properly . If the user accidentally pressed the wrong buttons, turned on the wrong mode, entered through the software interface, then the screen of the working TV will be black. You need to return to the correct mode. If you can’t fix the error on your own, you will have to contact the master.
6. Take the TV to a workshop if it was damaged during a thunderstorm . In this case, it is unlikely that it will be possible to make repairs on your own.

Most often, the channels on the set-top box disappear due to the erroneous actions of the users themselves, ignorance of the digital television coverage area. You should not fix a serious problem on your own, so as not to make it worse, it is better to contact a qualified master.
