When watching TV, there is always a signal interruption, is it the reason for the set top box?

When watching TV, there is always a signal interruption, and the reason for signal input is mostly the reason for set-top box.

One, when using a satellite antenna, there will be signal interruptions in the following situations:

1. The elevation angle and deflection angle of the pot are touched by the wind or people, and deviate from the best state;

2. The feeder from the high-frequency head to the set-top box is broken or the heads at both ends are not done well or screwed well;

4. The set-top box is faulty.

Second, with a digital TV set-top box, the signal will be interrupted in the following situations:

1. Power failure or equipment maintenance in cable TV room;

2. Cable TV line failure or amplifier damage;

3. The feeder head from the inlet line to the set-top box is not done well or screwed well;

5. The set-top box is faulty.

There's a white wire connected to the set-top box,Look at the head at the connection,,Is there a problem,,Lock the head tightly or move the head left and right,Look at whether the picture of the TV has returned to normal,,, If there is recovery, change the head,,If there is no change。。 Check whether the other connections are plugged in,,, or directly dial the service of the local radio and television network**,

Kindness. Basically, the set-top box has been used for too long. Aging lines. Just change it.

It seems that the set-top box is dead, and it is OK to replace the set-top box

Check it out with a local ** businessman.

Step 3: Look at whether the cable of your cable TV is plugged in normally, whether the interface is loose, and there is no RF signal detection equipment at home, so what you can do is to see if the appearance is plugged in tightly.

The reasons for the signal interruption of the set-top box and the solutions are as follows:

1. The plug of the signal cable connecting the set-top box is loose or has fallen. Solution: Reconnect the signal cable to restore the complete recovery signal.

2. The direction of the quasi-satellite is shifted by the lid of the pot or the high-frequency head is broken, and there is an obstacle in the direction of the satellite with the lid of the pot. Solution: It is necessary to adjust the position of the lid of the small pot accurately, remove the obstacles, and replace the high-frequency head.

3. Signal interruption caused by wired front-end failure. Solution: You can only wait until the cable staff completes the repair and restores the signal.

4. The signal demodulator of the set-top box is broken. Solution: Ask a professional to replace the signal demodulator.

The set-top box is a device that connects the TV with an external signal source, the full name is the digital conversion box, which can convert the compressed digital signal into TV content, so that users can use the existing TV set to perform digital TV programs, and carry out interactive digital entertainment, education and commercialization activities through the network.

Hello, received your question here. If the TV screen appears on the set-top box and then prompts "no signal" or acceptance, this phenomenon proves that the audio ** line (red, yellow, white) connection between your set-top box and the TV is basically fine, but the TV shooter does not have a frequency input signal cable (note: not the red, yellow and white) is not connected to the RF input port of the set-top box, or the TV RF input signal cable is not connected to the terminal box on the wall, or there are other open circuits in your room.
