It s been useless for a long time, and now there s no signal, how can you do love?

Turn on the TV,Turn on Huhutong,Use the remote control to quickly press F1Four times,Then press the confirm button,See what the signal quality is,It must be greater than 65%,Otherwise, you need to adjust the direction of the small pot。 If the signal quality is normal, you need to scan the *** in the lower right corner, pay attention to the satellite live broadcast, and enter it according to the relevant prompts to complete the authorization.

Hello, there will be no signal if the household is not used for a long time, and this needs to be reinstalled and debugged to solve the problem.

If it's not the kind of household pass that is upgraded,You may have to upgrade,If it's upgraded,Or if it doesn't work for a year or two, there is no signal,You can find someone who installed it at the time or someone who specializes in installing it for TV maintenance to debug it for you to receive the signal。

The one you use.

It should be piracy.

of,Genuine Hutong will often be upgraded,Upgrade your Huhu Tong will have no signal and can't **,If you can find someone to help you upgrade,You can continue to watch,Otherwise, you can only throw it away,Now no one uses this thing,It's all broadband TV。

First of all, connect the set-top box to the power supply.

Check if the set-top box TV signal light is green.

If the green light is on, the signal is normal, if the red light is on, there is no signal, 1If the TV screen indicates that the signal is interrupted, the lack of signal may be due to weather conditions, and the signal will be available after the weather is clear.

2.It is possible that the receiving antenna of the satellite is shifted and the signal cannot be received.

The direction of the satellite receiving antenna can be adjusted appropriately, and after adjusting to the accurate latitude and longitude, the signal of the set-top box is green, 3If there is no signal for a long time, then it is necessary to consider whether the "signal line" is connected normally, or whether the "receiving and high-frequency head" is faulty, and find out the specific reason, which can solve the problem of no signal in every household.

Reason 1: The feeder is not well connected to the receiverSolution: The feeder needs to be checked and connected to the feeder Reason 2: The pot is not adjusted well.

Solution: After the small pot lid and the receiver are connected, press the F3 button on the remote control (or the star adjustment key), and the signal strength and signal quality will be displayed on the TV, and the strength is 60%--70% (this must be there, it does not mean that the feeder is not connected well or the high-frequency head is bad); The signal quality is 0, now you can adjust the lid of the pot, turn the antenna up and down left and right to find the star, the general orientation is southwest, and look at the signal quality when you turn to make it the highest (the general receiver reaches 50% to reach the threshold, and the image can be produced). Adjust the angle and direction of the pot surface, you can have signal quality, and if you can't find the signal, you can try to change it to other frequency bands.

Take a look.

Take a look.

Questions. I watched it normally, but in the morning I connected the cable from the set-top box to the TV once, and there was no signal when I connected it again.

Pro: Maybe it's because of the set-top box.

It is recommended that you debug carefully.

Questions. The cable is disconnected once, and it will not work if you connect it again.

Pro: It may be because of the line, it is recommended that if you can't solve it, find a professional to take a look.

Questions. I'm in Hai Duong.

I can't find any information for you.

Questions. None of the other keys can be used.

Pro: It's because of the set-top box line, I recommend that you find a professional to repair it.

When there is no signal, the processing steps are as follows:

1. First of all, the wire should be connected, and the signal strength and signal quality bar will appear when the information key is pressed (the signal strength is about 50 70 after the line is connected).

2. Adjust the elevation angle, adjust the signal strength to the highest, and then adjust the azimuth angle. So, slowly turn the pot from due south to west, and the signal quality appears and turn it to the highest.

3. 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, and fix it.

2.If method 1 is useless, press the remote control board F1, the first installation and signal detection, the frequency sequence number is adjusted to 2, confirm, the display signal should be about 70% later, exit later, try a few more times, sometimes the response is slow, you return or 1 channel.

3.Still no, adjust the direction of the lid, I can't remember the direction, you can get there.

4.None of the above, it may be broken.

1.Press the F3 button of the remote control to adjust the star button;

2.Squat behind the small pot and slowly turn the chassis first to maximize the signal quality;

3.Adjust the elevation angle to maximize the signal quality;

If the card is removed and then installed, it will not be able to be seen.

There is no signal, it may be that the feeder is not connected to the receiver well, just check and connect the feeder. Of course, it is also possible that the pot has not been adjusted well, and it only needs to be adjusted in the following way. Here's how:

1. When the Huhu only shows the signal strength but no signal quality, first check whether the signal line is connected.

2. Then connect the receiver and the set-top box with an electric line of sight, so that the signal can be received.

3、Then connect to the TV with a set-top box,Generally, it is connected with three wires of red, yellow and white,Pay attention to the connection of red to red、Yellow to yellow,Otherwise the TV will not receive the signal。

4. After the connection is completed, manually align the satellite test signal back and forth until the TV program is clear.

5. If no errors are found in the above steps, you can replace a set-top box device and debug it again.

Notes:

Installation equipment: 1. Assemble the antenna and install the high-frequency head: install and connect the antenna and the high-frequency head according to the instructions (the pot body is generally pressed by the seller, including the elevation angle).

2. Cable: Connect the cable on the set-top box with the cable on the TV.

3. Adjust the antenna elevation angle and azimuth angle: elevation angle: scale The antenna elevation angle of the previous preparation work is -22 °, if the scale on the antenna has been corrected to the deflection angle, the queried angle is used; Azimuth: due south to west.

There are many reasons why there is no signal in Huhutong, it may be that Huhutong has no signal or has not adjusted the orientation, or it may be that the set-top box is not powered on and the remote control panel display is a problem, which needs to be investigated one by one.

1. There is no signal for Household Pass.

You need to check and connect the signal cable, and the signal strength and signal quality bar will appear when you press the information key.

2. The orientation is not adjusted.

Adjust the elevation angle, adjust the signal strength to the highest, and then adjust the azimuth. See if all the tables are taken down and fixed.

3. The set-top box is not powered on.

Check whether there is power in the power socket, and then check whether the power cord of the set-top box is obviously damaged or broken. Whether the power switch is turned on, if the above is normal, it may be that there is a problem with the power board of the set-top box.

4. Remote control panel display.

Replace the remote control or a new set of batteries, and replace the front panel display of the set-top box.

Notes:1. If the problem is still not solved, find a professional for maintenance.

2. In the process of checking the problem, do not change the parameters at will.
