How to Set Up a TV Tuner on a TV
We will consider how to properly attach your receiver to a satellite dish without the help of specialists if, for whatever reason, the settings in the tuner were incorrect (bought a new tuner; “flew off” firmware; “poked around”where not worth it; “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.
The first step is to determine which satellites the antennas are tuned to. It will not be difficult to do this 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 for 3 satellites: Amos, Sirius (Astra) and HotBird. Sometimes an additional antenna with one head (converter) is placed on an additional satellite. We recommend recording the list of received satellites in “column” and opposite each satellite. any frequency from this “satellite”, on which “is sitting” a large number of channels.
If there is easy access to the satellite dish:
The image indicates which satellite a particular head is tuned to. A cable (or several cables) emerges from 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, it can be determined which satellite the number on the switch corresponds to. Thus, we mark in the list opposite each specific satellite the corresponding diseqc switch port number. 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 in main menu paragraph settings (installation, installation) antennas. If there is no such item, in some tuners these settings may be in the item “channel search”. Entering this menu item, we should find the satellite settings (satellite name, type LNB, DiSEqC, polarization, LNB power, signal level and quality scale, etc.). In different receivers, these signatures may vary slightly.
2. Click on the name of the satellite, a list of embedded satellites appears. From all the variety we choose one of those that we need.
3. Go to the DiSEqC tab (DiSEqC 1.0), select the number corresponding to the selected satellite from the drop-down list (for example: “3”, or “LNB 3”, or “FROM”, or “3/4” (where 3 is the switch port number, 4 means that our switch has only 4 ports)). In some receivers, diseqc numbering is not digital, but alphanumeric, for example, LNB “A”, LNB “B”, LNB “C”, etc. Thus “tie up” other satellites to their DiSEqC switch ports.
4. By pressing the button “EXIT” remote control, exit the menu. When asked to save the settings, we agree by selecting the appropriate answer option and clicking “Ok”.
If access to the satellite dish is difficult:
In this case, it is also possible to solve the problem, but by the method “poke”.
From the above method, perform steps 1 and 2.
Next, go to the tab “TP number” (“Frequency”,”Transponder”) The list of frequencies from this satellite appears. We select the working frequency in it from our previously compiled list, click “Ok” on the remote.
We follow the DiSEqC tab (DiSEqC 1.0), select an arbitrary number from the drop-down list (for example: “3”, or “LNB 3”, or “FROM”, or “3/4” (where 3 is the switch port number, 4 means that our switch has only 4 ports)). Click “Ok”to fix the value and look at the signal quality scale. If the indicator has significantly increased on the scale, 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 choice of the next satellite. Next, we 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 arriving at the receiver. In this case it is worth calling a specialist for the correct diagnosis and elimination of this problem.
