Before the launch of cable TV and optical cable, many consumers used small satellite covers to receive signals to watch TV. However, after long-term use of small covers, there may be no signal. What should we do if there is no signal in the small covers? Let's learn it with Xiaobian.

First, what should I do if there is no signal in the small pot cover?

1, first of all, you should confirm whether the small pot cover of your home is blocked by other buildings or objects, and then you need to check the wiring of the small pot cover. When the connecting cable between the small pot cover and the TV is connected, you should start the test and use the remote control to call up the program information column. If there is no signal strength, there may be something wrong with the wiring or the tuner.

2. When the signal intensity is lower than 60%, it may be the direction of the small pot cover or the signal difference in the area where you are located, then you need to call up the information bar to check the specific value of the signal intensity. Generally, when the signal intensity is 20%, the TV will have an image.

3. If there is no signal from the small pot cover, then you need to move the small pot cover slightly for circular motion (the key direction is southeast), or lift one side of the base of the small pot cover for up-and-down motion and circular motion, and your eyes need to look at the image signal quality column of the TV. When you see the signal flashing and rising, you can basically determine the orientation, and then slowly adjust the orientation according to the up, down, left and right until the image of the TV is clear.

Second, how to install the small pot cover

1, installation materials and tools:

60 cm antenna, "omni-directional" frequency down converter, RCA-992 special receiver, TV set, wrench tool for antenna assembly, etc.

2, survey terrain:

Find the east direction, that is, the compass azimuth is about 120 degrees, and it can be installed on the ground or on the wall.

3, fixed line:

When installing the antenna, it should be assembled according to the instructions in the assembly instructions, and the antenna should be fixed with brackets, usually on the ground or on the wall, and the LNB should be installed on the antenna LNB fixing frame, and the inductive antenna of LNB should be straightened according to the horizontal polarization direction of166 E satellite.

4. Connecting cable:

Connect the receiver with the video line and audio line of the TV set by using the AV cable, and then connect the receiver with the small pot cover by using the closed line.

5. Receiving signal:

Turn on the TV and receiver, then press TVAV, and point the lid of the small pot to the southwest.

The above is a detailed introduction about how to do without signal and how to install the lid. Friends who want to install the lid can learn from it. In addition, when debugging the lid, be sure not to have a house blocking the southwest direction of the lid.
