How to retune my tv: step-by-step guide

A television that is not properly retuned can cause a number of problems. The most common problem is that the television will not receive all of the channels that it is supposed to.

This can be very frustrating, especially if you are trying to watch a particular program that is only available on one of the channels that you are not receiving.

Luckily, there are a few things that you can do in order to learn how to retune TV properly.

Why Does The TV Need To Be Tuned In?

When you set up your TV for the first time, you connect it to your TV aerial to scout for channels. To make the live TV work correctly, you will have to tune your aerial in manually to the channels it is picking up.

The TV has to be tuned because there are many TV transmitters present all around, broadcasting on various frequencies, yet your TV aerial will be looking for one of them.

To have your TV know what channels/frequencies it should be pointing at, you need to make sure it’s tuning in. As the TV scans for frequencies, it’ll find TV channels available and store them on your screen.

You may be thinking, why not use the same frequencies on all TV transmitters to avoid tuning?

Well, if all the transmitters broadcast on the same frequencies they would interfere with one another. The quality of your TV signal would be severely diminished, as a result.

When two signals are on the same frequency, the stronger signal overpowers the weaker one. This phenomenon is Co-Channel interference and it can completely ruin the quality of your TV signal.

How do I retune my TV automatically?

If your television has an auto-tuning or self-scan feature, you can use this to retune the channels. This is usually found in the menu system on your television. If you can’t find it, consult your television’s instruction manual.

Once you’ve found the auto-tuning feature, follow these steps:

Step 1: Press the menu button on your remote control.

Step 2: Use the arrow keys to navigate to the settings or setup menu.

Step 3: Navigate to the channel menu or the tuning menu.

Step 4: Select the auto-tune or self-scan option.

Step 5: Your television will now scan for all available channels. This may take a few minutes.

Step 6: Once the scan is complete, you should see a list of all the channels that are now available to you.

Step 7: You can now exit the menu and start watching TV!

Before you manually retune

Before you manually retune, here is a step you should keep in mind.

Be sure you are choosing the right channels for your region before you start using your aerial.

You will need to enter these numbers in manual tuning, here is an example:

  • BBC A – ch 50
  • D3&4 – ch 59
  • BBC B HD – ch 54
  • SDN – ch 58
  • ARQ A – ch 49
  • ARQ B – ch 55
  • COM7 HD – ch 31

Manual Tuning TV Process?

If your television starts displaying a snowy picture or one with ghost images, it probably means the channels have become unscrambled and you need to retune the TV.

Retuning takes only a few minutes and can be done without any special equipment. You will need to know your TV type and the location of your nearest transmitter in order to retune.

Here is how to do it manually:

Step 1: Click on the menu button on your remote.

Step 2: Look for a Set-Up or Installation option and choose one.

Step 3: Search for Manual Retune or an option that says something similar. You may get a prompt for a passcode. This is given in the product manual of your TV. If not, enter 1234 or 0000.

Step 4: Here, you will need to enter the channel numbers.

Step 5: Repeat the previous steps for each channel group until you’ve finished the entire process.
