Let's consider how to properly connect your receiver to a satellite dish without the help of specialists, if for some reason the settings in the tuner were disrupted (bought a new tuner; "firmware" flew off; "poked" where you shouldn't; "helped" children, etc.) and instead of broadcasting your favorite channel, we see a terribly unpleasant inscription "no signal".
There are 2 ways to solve this problem yourself.
First of all, you need to determine which satellites the antennas are tuned to. This will not be difficult if you remember which channels were previously available to you. From the following table you can determine which satellites these channels belong to. Most often, one antenna is installed on 3 satellites: Amos, Sirius (Astra) and HotBird. Sometimes an additional antenna with one head (converter) is installed on an additional satellite. We recommend that you write down the list of received satellites in a "column" and opposite each satellite - any frequency from this "satellite", on which a large number of channels "sit".
If there is easy access to the satellite dish:
The image shows which satellite a particular head is tuned to. A cable (or several cables) comes out of each head, connecting it to a special diseqc switch (usually located behind the antenna). All inputs on the switch are numbered (lnb 1, lnb 2, lnb 3, etc.). Having determined from which head, to which input of the diseqc switch the cable is connected, you can determine which satellite the number on the switch corresponds to. Thus, we mark in the list opposite each defined satellite the corresponding port number of the diseqc switch. It is important not to make a mistake, different satellites cannot have the same port number.
Having compiled such a list, you can proceed to the receiver settings. To do this, follow these steps:
1. Turn on the receiver and find the antenna settings (installation) item in the main menu. If there is no such item, in some tuners these settings may be located in the "channel search" item. Entering this menu item, we should find the satellite settings parameters (satellite name, LNB type, DiSEqC, polarization, LNB power, signal level and quality scale, etc.). In different receivers, these captions may differ slightly.
2. Click on the satellite name, a list of embedded satellites will drop down. From all the variety, we choose one of those that we need.
3. Go to the DiSEqC tab (DiSEqC 1.0), select from the drop-down list the number corresponding to the selected satellite (for example: "3", or "LNB 3", or "C", or "3/4" (where 3 is the port number of the switch, 4 means that our switch has only 4 ports)). In some receivers, the diseqc numbering is not digital, but alphabetical, for example, LNB «A», LNB «B», LNB «C», etc. Thus, we "tie" other satellites to their DiSEqC switch ports.
4. By pressing the "EXIT" button on the remote control, exit the menu. When asked to save the settings, agree by selecting the appropriate answer option and pressing "OK".
If access to the satellite dish is difficult:
In this case, it is also possible to solve the problem, but already by the "poke" method.
From the above method, we perform steps 1 and 2.
Next, go to the "TP Number" ("Frequency","Transponder") tab - a list of frequencies from this satellite drops down. Select the operating frequency from our previously compiled list, press "OK" on the remote control.
Go to the DiSEqC tab (DiSEqC 1.0), select a random number from the drop-down list (for example: "3", or "LNB 3", or "C", or "3/4" (where 3 is the port number of the switch, 4 means that our switch has only 4 ports)). Press "OK" to fix the value and look at the signal quality scale. If the indicator on the scale has increased significantly, then the selected satellite corresponds to the checked switch number. If not, try the next DiSEqC number in the same way until the quality scale increases. If the result is positive, leave this value and return to the selection of the next satellite. Next, select the DiSEqC port number by analogy with the previous satellite.
Then it remains to perform step 4 of the previous method.
If everything is done without errors, and the channels still do not want to be displayed, most likely there are problems with the signal coming to the receiver. In this case, you should call a specialist for proper diagnostics and troubleshooting.
