What should I do if the small TV pot suddenly has no signal?

Check the connection line between the set-top box and the pot, there will be no signal if the plug of the connection line falls off and is loose, and there will be no signal if the pot is offset by the wind, and the pot surface should always be aligned with the satellite.

It belongs to the electronic tuning selector, which has the advantage of saving spectrum resources.

Determine the cause of the failure.

When receiving an analog satellite signal, if an image is received, and noise.

If there is a lot of noise, the cause of the fault can be determined based on the noise situation. Specifically, when the screen is full of black noise, it means that the frequency of the receiver is high and should be lowered; When the screen is full of white noise, it means that the receiver frequency is low and should be turned up.

If there is a lot of black and white noise on the screen, it may be the installation, focus, polarization, and azimuth angle of the high-frequency head.

and improper adjustment of elevation angle, or there are buildings, trees and other obstructions in the direction of the antenna, which should be solved.

Possible causes and solutions for sudden no signal on satellite TV:

1. The plug of the signal cable connecting the set-top box is loose or has fallen off.

Solution: Reconnect the signal cable to restore the signal.

2. The lid of the pot is shifted in the direction of the satellite or the high-frequency head is broken.

The reasons why there is no program in the TV pot are as follows:1. The signal quality is not good, resulting in no program.

2. There is a problem with the receiver, and the receiver I bought is broken and cannot accept the signal, resulting in no program in Qinshan.

3. The TV program is old, so the satellite can't receive the signal, and there is no program.

5. The show has no resources, so there is no program.

Precautions for using a TV pot.

The first thing to do when using a TV pot is to determine which TV signals you want to **, and which satellite TV you like to watch, because the satellite TV receiver receives the TV signal of the satellite in the sky, but the TV program on a satellite is fixed.

After determining the TV program you want to watch, you need to put the satellite TV receiver in this direction, and adjust its position through the remote control after installation. And when you determine the installation location of your satellite TV receiver, you need to take a look at the general direction of the satellite TV receiver antenna, and see if there are buildings, trees, etc. in front of you, if there is a block, then you have to place the antenna in a high place.

Extended information: Satellite TV receiver refers to the electronic equipment that converts the output of the satellite frequency downsizer to the audio signal or radio frequency signal. Satellite TV receivers belong to electronic tuning selectors, which have the advantage of saving spectrum resources.

First of all, connect the cable with the set-top box and high-frequency head.

Then turn on the TV and use the remote control of the set-top box to bring up the signal quality icon.

Then turn the lid of the pot, and wait for the signal quality to turn green, and there will be a table above 50%.

1) First of all, install the small pot satellite receiver, and put the lid of the pot receiving the signal facing southwest.

2) Take out a yellow and white cable, and connect the display of the search channel at one end.

3) The other end is connected to the TV, both need to be connected with the color check mark, and then connect the TV and the small pot.

5) Adjust the small pot satellite when the numbers keep jumping.

6) When the adjustment is above P45, press Confirm to watch TV.

2. TV pot adjustment method 2.

1) Make sure that the column is adjusted to vertical.

2) Then adjust the polarization angle of LNB to the appropriate position, and adjust the elevation angle of the antenna accurately.

3) Adjust the azimuth angle of the antenna to the approximate position, and then rotate the antenna slowly, remember to just let the antenna rotate left and right, and do not use too much force to change the elevation angle that has been adjusted. In this way, because the polarization angle and elevation angle of the antenna have been adjusted very accurately, once the azimuth angle of the antenna reaches the target value in the process of rotating left and right, the signal quality will appear, and then after careful adjustment, the signal quality will rise to about 80%, and then it will be aligned with the star, and you can watch the wonderful TV program transmitted by the satellite normally.

First of all, it is necessary to determine whether the local satellite signal has been upgraded, if the upgrade needs to be re-decrypted, the second is to the star, call up the satellite signal quality, the satellite selects Zhongxing 6b, look at the change in the quality of the signal source, and the general signal grows to green, which is a very critical step, that is, to align the small pot at the satellite, generally in the southeast direction, and the ground angle between 15-30 ° (Zhongxing 6b, Shandong region, other remote locations will be slightly deviated), adjust the direction of the pot lid gently, If the action is too large, it is easy to lose the signal instantaneously. Finally, press the channel search button after the star, generally the second button on the right at the bottom of the remote control (buy a small pot is a remote control), and then wait for a period of time for all the channels to search out. This is a search method for the smallest small pots that can only be pointed at one star, and is not suitable for other larger pots.

Summary. If there is no signal, it is recommended that you check the connection on the TV side for any poor contact, including. Check your pot signal head.

If there is no signal, it is recommended that you check the connection on the TV side for any poor contact, including. Check your pot signal head.
