Why don't you see La 1 and La 2 on television? Look at this solution

There are many users who have encountered trouble watching certain TV channels at home. When connecting certain strings, the message of "no signal" on the black screen. Or it can also happen that the channel is tuned, but with so much interference that it is impossible to watch TV. And this is more common with channels Spanish Television. Why can't I see La 1 and La 2?

The situation can become very irritating, but as always, there are solutions. If these are the only channels that we cannot see, it is most likely that we will have to proceed to a DTT retune (Digital Terrestrial Television). This is the first step we should try:

Retune channels

Firstly, It must be taken into account is the type of housing where we reside. The process will differ depending on whether we live in a single family home or in a building with more neighbors.

In the first case (or in a building where there are less than three dwellings) it is not necessary to hire an installer. This is because the house is already prepared to reproduce the channels even if they have changed frequency. If that is our case, or if we have a home installation with broadband amplifier, retune will be easy.

In other cases, the antenna will have to be adapted using the services of a professional. This must install a programmable control unit and a single channel amplifier. This means that your pocket will have to be scratched.

If we are in the first case, which is the most common, How to retune the channels? You just have to follow the following steps:

1. To begin with, we will turn on the tv and, if necessary, also the DTT receiver.
2. Then we will press the button "Menu" from our remote control. In some models, instead of the text, the icon of a house is drawn.
3. Using the arrows on the remote control, we will scroll through the different options that appear until we find the one for "Installation" (in some cases it may appear as "Settings"), and we will validate with the button «OK».
4. Using the arrows on the control again, we will look for the option to "Channel search" (can also come as "Tune in to new channels", validating again with the button «OK».
5. Once this is done, the channel search process will start automatically, which may take several minutes. Upon completion, a notice will appear on the TV screen.
6.  After retune channels, we will be able to check if the question that we raised at the beginning (the one of why the 1 and the 2 are not seen) has been resolved. In the same way, we will also have the opportunity to organize the channels according to our preferences by accessing the options «Sort channels» o «Create list of favorite channels» through the «Menu».
7. To finish the retune process, we will simply press the button "Go out" o Exit.

Disconnect Chromecast

But if even after retuning these channels the display is still bad, with numerous interferences, it is possible that the error comes from an external device connected to our television set. And in many cases, that device is Chromecast. This has been reported by numerous users.

As you probably already know, Chromecast is a device that connects our TV to the Internet through a WiFi network. It is the cheapest and easiest way to turn a normal TV set into a Smart TV.

Once the connection between the Chromecast and our mobile phone is established (it can also be done from a tablet or a computer), we can log in and control the sending of content to the TV wirelessly. Thus, the mobile becomes a kind of remote control. The leisure possibilities are endless: for example, we can watch YouTube videos or our favorite Netflix series on TV where the Chromecast is installed.

The truth is that it is a great invention, as long as it does not cause problems like the one we are dealing with here: Why can't I see La 1 and La 2?

Chromecast connection to TV can be done via HDMI or USB. This device has WiFi connection capacity to connect to the home wireless network. This can cause interference in our television tuner. The consequence is that some TV channels cannot be viewed well. It may be the reason why 1 and 2 are not visible.

In these cases the antenista will not be able to do much to help us. We can solve the problem ourselves disconnecting Chromecast or any other device with WiFi connection that we could have connected to our TV set. Once done, the display should be correct again.

Does this mean that we have to give up Chromecast in order to watch certain TV channels? Not necessarily. In many cases, it is enough to reboot the device following these steps:

 First of all, we have to make sure that the Chromecast is turned on and connected to both the network and the TV.

• We start the application Google Home on the phone and we go to the option "Devices", that we will find in the upper right corner of the screen. There we will select "Chromecast".
• To restart the Chromecast, you just have to access the option "Restart". A confirmation pop-up window will appear to verify that we want to run that command. We will press "To accept".
• After this, you will only have to wait a few minutes and the restart will be complete.

After doing this, it is time to verify that Chromecast has stopped interfering with the viewing of television channels where we had the problems. If so, the problem is solved. If the problem persists, there will be no choice but to do without Chromecast.
