What is the reason why the live broadcast machine of Zhongxing No. 9 has a signal and no program

Your machine may be about to be upgraded.

The process is as follows: First open the menu > System Settings > Password 9999 > Restore Factory Settings > Exit Menu > Open Menu > System Settings > Password 9999 > Manual Search > Frequency Sequence Number Change to 2 >> Show 16 Stations & 4 Broadcasts >> Exit Menu >> Show 005 Channel Updated" Press OK >>

Mine is almost the same as you, now it's okay, unplug the signal cable, turn on, select the menu, select the system settings, enter the password 9999, select the factory reset, insert the signal cable, the player moves to search, press the right volume button, press the confirm button.

Players move to search, select serial number 1, press confirm key to search, select serial number 2, press confirm key to search, select serial number 3, press confirm key to search, select serial number 4, press confirm key to search, select serial number 5, press confirm key to search, press confirm key, return to the menu, select automatic search, press confirm key, and that's it!

At present, Zhongjiu has stopped the 11840 parameter program, and the other three parameters of the program have been repackaged, 11880 is 16 sets of TV, 4 sets of ** radio, 11920 is 16 sets of TV, 11960 is 14 sets of TV. Provincial radio broadcasts have disappeared.

After 11840 is stopped, the program signal is still there, and the follow-up may increase the program, so everyone will continue to pay attention.

The reason why the Zhongxing 9 received fewer channels:

After the upgrade of the Zhongxing-9 satellite, the parameters were stopped or modified, and most of the programs were encrypted and transmitted, resulting in the set-top box programs not being able to be watched, which required a regular Zhongxing-9 third-generation positioning encryption machine to watch all the programs of the Zhongxing-9 satellite.

Installation method: 1. Press the "Menu" button on the remote control to enter the "Main Menu" interface and select "System Settings";

2. Enter the password "9999";

3. Select "Installation and Signal Detection" in the "System Settings" interface (selected by default), and press the "Confirm" button of the remote control twice. Stand behind the satellite dish and slowly turn the front of the satellite dish from due south to the direction of the satellite.

Moving (it is recommended to turn slower than the speed of the second hand of the watch). During the rotation process, always keep an eye on the TV satellite receiver debugging interface, the "signal strength" and "signal quality" change indication signal turns green.

When the action is stopped, it means that the satellite has been preliminarily identified and the satellite signal has been locked;

4. Network connection settings. IP settings: , port settings: 4567 or 04567;

5. The area code is set to the first six digits of the local ID number;

6. Turn off the power of the set-top box, insert the mobile ** card and smart card, and then turn it on;

7. Select "Base Station Information" in the system settings and press Confirm;

This is caused by the upgrade of the middle nine system, to put it bluntly, it has changed the frequency, you can operate the letter shooting according to the following method:

1: Disconnect the feeder first (that is, cut off the signal).

2: Turn on the computer again, press the "menu" on the remote control to enter the "System Settings", enter the super password "9999", select "Restore factory settings", then plug in the signal feeder, and then automatically or manually search for frequency and several channels, the first frequency point has been changed to no station, the second frequency point 16 stations and 4 broadcasts, the third frequency point 16 stations, the fourth frequency point 14 stations, call the head (a total of 46 stations and 4 broadcasts).

3: Exit the system settings, OK, enter CCTV-1, haha, you can watch TV again, normal

Mine is the same as yours, now it's fine.

Unplug the signal cable, turn it on, select the menu, select the system to set it, enter the password 9999, select the factory reset, insert the signal cable, search for the player, press the right volume button, and press the key to confirm the preparation of the mountain.

Players roll the base search, select the serial number 1, press the confirm key to search, select the serial number 2, press the confirm key to search, select the serial number 3, press the confirm key to search, select the serial number 4, press the confirm key to search, select the serial number 5, press the confirm key to search, press the confirm key, return to the menu, select automatic search, press the confirm key, and you can!

First of all, it is very noisy to sell the middle nine receivers. There are generally few sales in places that are too prosperous in the urban area, after all, cable TV or cable TV digital set-top boxes are installed in the city, so if you sell this, it will be very difficult to sell, and the inspection and confiscation of the radio and television department is the most in the urban area, so there are few sales. There are more needs in remote places such as suburbs!!

Now the ** of the receiver has been relatively transparent, and a complete set is about 200 yuan each.

Remember: buy must buy genuine, with a serial number, because in the future satellite software upgrade needs to bend Qi to use, such as buried bent Lingguo does not have a serial number or the sequence Ha shows are ffffff a string of such f is not good, this reputation oh serial number, once the satellite is upgraded in the future, this machine can not be used!!

Gauss Bell Free Machine October 2009 Upgrade Steps.

1.Turn off the power of the set-top box when the TV is receiving the signal from the set-top box, and turn off the signal cable connected to the antenna. Disturbance.

2.Turn on the power supply of the set-top box.

3.Press the "Menu" button on the remote control (the TV displays the "Main Menu").

4.Select "System Settings" and press "Confirm" (the TV display asks for a password).

5.Enter the password "9999" and press "Confirm".

6.Select "State Richai Factory Reset" and press "Confirm".

7.Connect the signal cable connected to the antenna (the TV shows the signal strength and quality, both green).

1. First of all, look at the signal strength, if the signal strength is also up and down, it means that the signal line is not in good contact;

2. If the signal strength is constant and the value is high, it may be that the antenna angle is a little wrong or there is a signal source interfering;

3. In the case that the above problems are ruled out, it may be that the pot body is deformed or there is a problem with the high-frequency head.

The angle of the star is actually very small, check the satellite frequency table and you will find that there is a satellite almost every 2 ° or so in the sky, so be patient when adjusting the star, I believe you should be successful. Thank you!

Mine is the same as yours, now it's fine.

Unplug the signal cable, turn on, select the menu, select the system settings, enter the password 9999, select the factory reset, insert the signal cable, player dynamic search, press the right volume key, press the confirm key to player mobile search, select the serial number 1, press the confirm key to search, select the serial number 2, press the confirm key to search, select the serial number 3, press the confirm key to search, select the serial number 4, press the confirmation key to search, select the serial number 5, press the confirm key to search, press the confirm key, return to the menu, select the automatic search, press the confirm key, and you can!

This is caused by the upgrade of the Middle 9 system, to put it bluntly, it has changed the frequency, you can operate according to the following methods:

1: Disconnect the feeder first (that is, cut off the signal).

2: Turn on the phone again, press the "menu" on the remote control to enter the "System Settings", enter the super password "9999", select "Restore factory settings", then plug in the signal feeder, and then search for the channel automatically or manually, the first frequency point has changed to no station, the second frequency point 16 stations and 4 broadcasts, the third frequency point 16 stations, the fourth frequency point 14 stations, (a total of 46 stations and 4 broadcasts).

3: Exit the system settings, OK, enter CCTV-1, haha, you can watch TV again, normal

Hello, this kind of receiver is an exclusive access to receive China's self-developed Zhongxing-9 satellite program.

The set-top box has a total of 58 programs, including 16 sets of CCTV.

Programs and provincial capitals serve rural areas that are not accessible by television networks.

The transmission and reception of the nine satellite programs is realized by circular polarization, divided into left-handed polarization and right-handed polarization, the receiver applies the voltage control mode to realize the mutual conversion of the two polarizations, this conversion must have a polarization conversion circuit, called the polarization switching circuit, the circuit realizes the conversion by switching two voltages, and the left-handed polarization voltage power supply is about 18V, and the right-handed polarization voltage is about 12V.

CCTV programs are right-handed polarized programs, and there are several reasons why CCTV programs cannot be received:

2.If possible, replace a new head to try, or borrow a normal receiving household set-top box from a neighbor to connect to their own antenna, if the result is still not received, it is a bad frequency converter, if it can be collected, it is a problem with their own set-top box.

3.The polarization switching circuit is damaged, and there is a polarization switching circuit based on the model SS8550 triode on the motherboard of the set-top box (the design of various models is different, and the circuit is also different), and the damage causes only 18V voltage to supply the outdoor high-frequency head and no right-handed polarized 12V voltage supply, so it cannot receive the right-handed part of the program, generally the 8550 triode breakdown damage is the majority, and it is good to replace it, and it is not excluded that other components of the polarization circuit are damaged, but it is rare, and the general main chip rarely fails.

4.Power strip issues. If the right-handed program is not received, a set of 15V voltage may be lost, and the 12V voltage is not provided to the outdoor high-frequency head.

It is also possible that the overall increase in voltage causes the polarization voltage to increase by 12V to more than 15V, which is generally the 1000UF filter capacitor of the main 5V voltage group of the power board.

Caused by capacity loss, it can be replaced to normal, and the phenomenon of circuit desoldering and virtual soldering is not ruled out.

It's because you didn't find the preparation position,When the Zhongxing No. 9 small pot adjusts the signal,The direction of the small pot to prepare:south-west degree,The elevation angle of the small pot:degree,If you don't find the preparation,After you connect the small pot,Turn on the TV,Use the remote control to press the menu--Parameter setting--Antenna parameter setting,You will see two information bars showing % under the screen,The upper one is"Signal strength",The lower one is"Signal quality",If there is no signal, your "signal strength" is 60%,And it remains the same,"Signal quality"It's empty, which is 0.

You use a wrench to loosen the up and down adjustment screws and left and right adjustment screws of the small pot, and then according to the general direction mentioned above, gently adjust the position up and down, left and right, the amplitude in the process of adjustment must be small, and pay attention to the "signal strength" displayed on the TV at any time, and when the "signal strength" changes, and reaches the highest (up to 90% or more), then you will find that the "signal quality" also appears (up to more than 80%), if you think it is the best state, okay, please lock your small pot, Press the exit of the remote control and it's OK,There will be a program on the TV.。

Don't worry about adjusting it slowly, it will definitely be able to tune it out, only a small range has a signal, and it is not easy to grasp.

Connect the wire, press the information key, the signal strength and signal quality bar appear, (the signal strength is about 50 70 after the line is connected) first adjust the elevation angle, adjust the signal strength to the highest, and then adjust the azimuth angle, in the ninth in our country is generally about 30 degrees from south to west, slowly turn the pot from south to west, the signal quality appears and adjust to the highest, and finally you can turn the high-frequency head a little, adjust the signal to the highest, see if all the stations are closed, fixed on it.

If you're still in place, the angle of the pot doesn't change, but your set-top box needs to be upgraded, and the high-frequency head probably needs to be replaced before you can receive the program.

Zhongxing Nine is the easiest to face the stars, the asterisk is super strong, facing the southwest sky, just fiddle with it a few times if you can't get it.

That's trouble.

First of all, look at the settings page of the receiver, the signal quality, there must be, if it is zero, it means that the connection is not connected well, broken, or simply the high-frequency head is broken.

Buy a new one, which is 10 yuan.

If the signal quality has a number, but there is no signal strength, it will be matched slowly, very slowly, and finally it can be matched, and if it is matched, the signal strength will have a number.

Tune to the highest, see if there is a program, if there is still wood, it is really the one upstairs who said, your machine, that is, the set-top box needs to be upgraded.

Go for it, it's 10 bucks too. gag
