What should I do if the satellite digital dual mode machine has no signal quality?

The satellite digital dual-mode machine has no signal quality, and the satellite pot is not connected well. How to adjust the satellite dish:

The first step is to open the TV and satellite set-top box, press the menu button on the remote control of the satellite receiver and then press the program settings to increase the program to input the downlink frequency, symbol rate, polarization mode in turn, take Fujian Satellite TV as an example: downlink frequency: 3706 symbol rate:

4420 Polarization Mode: Horizontal. (In addition, the local oscillator frequency should be correct to 5150).

The second step is to look at the signal quality and signal strength below, at this time, the signal strength is generally about 70% (if not, it means that the connecting feeder is not connected), and the signal quality is 0%. This requires adjusting the outdoor satellite antenna, (adjusting the antenna to adjust the triangle: azimuth, elevation, and polarization.

Go outside, turn the antenna up and down left and right to find the star, turn to see the signal quality to make it the highest, and then turn the high-frequency head clockwise back and forth to the best signal quality (the most important thing is to turn the pot slowly, be patient).

Finally, the satellite dish is compacted with bricks. And find a larger Coke bottle to cover the high-frequency head to prevent water from entering the high-frequency head.

First see if you switch to the live star mode (that is, the middle nine mode), and then adjust the pot, there can be no shelter in front of the pot, (such as a new tree with leaves, etc.), connect the wire, find: install and signal detection interface, first adjust the elevation angle, adjust the signal strength to the highest, and then adjust the azimuth, the middle nine in our country is generally about 30 degrees south-west, slowly turn the pot from due south to west, the signal quality appears and adjust to the highest, and finally you can turn the high-frequency head a little more, adjust the signal to the highest, and see if all the stations are closed, Fix it and you're good to go.

What they said is not unreasonable, and you can borrow a receiver to try it in your small pot, and you will know whether the high-frequency head is broken, or the receiver is broken.

The signal strength has been around 80%, indicating that the connection is normal and not facing the satellite.

First, if there is a signal on one of the stations, it may be that the antenna position is moved a little by the wind, you can first adjust the azimuth angle of the antenna, then fine-tune the elevation angle, and finally fine-tune the polarization angle until the signal quality is the maximum green value, second, if there is no signal in any station.

1. Adjust the antenna according to the above method.

2. If it does not work, it means that there is a problem with the polarization circuit in the high-frequency head or set-top box, it is recommended to change to other high-frequency heads to try it (some high-frequency heads have quality problems, and they are damaged for a long time, and similar problems may occur, before.)

I've seen it), or try it with another set-top box.
