Why Do I Have to Keep Retuning My TV (Due To Loses Channels)?

Why Do I Have to Keep Retuning My TV (Due To Loses Channels)?

It seems like every other time you turn your TV on, you’re greeted by static and forced to retune it. While retuning your TV only takes a few minutes, it’s a tedious process that you’d rather avoid. 

Your satellite and cable box seem to be in good condition, so you don’t think this is a result of faulty hardware. Could you be retuning your TV incorrectly? 

There are a few factors that can affect your TV’s tuning process, most of which cannot be controlled by everyday consumers.

So, why do you have to keep retuning your TV? 

Keep reading to find out! 

Why Do You Have To Keep Retuning Your TV?

Need retune TV

Here are a few common reasons why you have to keep retuning your TV.

The Channel Frequency Has Changed

Channels are broadcasted on specific frequencies which are prone to change by your provider. The channels’ frequency may change regularly or very rarely depending on your provider and general location. 

So, you may have to retune your TV so that it can pick up the channels on this new frequency. 

New Channels Have Been Added 

Your provider may have added a few new channels to your TV’s channel list. So, to update your TV’s existing channels and access the new ones, you will need to retune your TV. Bear in mind that the channel’s numbers may have changed with the addition of new channels. 

The Provider Has Changed the Channel Numbers

Sometimes, providers adjust the channel numbers even if they don’t add new channels, resulting in your TV needing to be retuned. Failing to do so will make it impossible to access your favorite channels since you won’t have the correct channel numbers. 

You’re in a New Area

If you’ve just moved across the country, you will most likely have to retune your TV so it can find and sync with the area’s local channels. This process will also get rid of any local channels on your TV since you’re outside of their broadcast range.

Changes in the Transmission 

Keep a lookout for a message from your provider informing you of changes in the transmission. This announcement should come a few weeks before any adjustments. 

These transmission adjustments may affect which channels are available to you and could be a result of new movements or innovations.

When You Need to Retune Your TV

Let’s go over a few issues to look out for if you suspect your TV needs to be retuned. 

  • All or some channels are lost/no longer available.
  • The channels are blurry.
  • The channels are out of order.
  • You’re watching the wrong regional news for your area.
  • The picture is breaking up.

Deeper Issues That Can’t Be Fixed By Retuning the TV

While your TV’s blurriness or lack of certain channels may be a result of it needing to be retuned, these issues could also be symptoms of a greater problem. 

These problems could be related to your TV’s hardware or software and cannot be fixed by retuning your TV. Instead, you may have to consult an experienced technician or update your TV. 

Aerial Fault

TV antenna

Check if there’s something wrong with your TV’s antenna by ensuring all of its rods are straight and in the proper position. You may also want to ensure it’s correctly connected to all of the necessary cables and facing the right direction. 

If you’ve recently experienced harsh weather conditions, your antenna could have been damaged by rough winds or rain, so it’s a good idea to carefully inspect it or call a technician to inspect it for you. 

Pending Updates

If your TV’s software has any pending updates it could affect its ability to find and display broadcast frequencies. Instead, it will be searching for broadcast signals that no longer exist, resulting in a “No Signal” message. 

So, head to your TV settings and install any available updates. You can also select the “Auto Update” option (if available) to have your TV install updates while in standby mode. If this option is not available, you’ll have to regularly install updates manually. 

This process varies depending on your TV’s make and model, so consult the user manual for further instructions.

How to Manual/Auto-Tune Your TV?

While auto-tuning your TV is certainly easier than doing so manually, there are a few glitches that can occur during the process. That said, manually tuning your TV is a time-consuming process that many users don’t have the patience for. 

Let’s look at a few pros and cons of auto-tuning versus manually tuning a TV, and discuss how to do both on popular TV brands. 

Auto-Tune vs Manual Tune

Wrapping Things Up

You may have to keep retuning your TV if the provider is changing the channel frequency, has added new channels, or has changed the channel numbers. Additionally, moving to a new area or the release of transmission changes may also prompt you to retune your TV. 

You’ll know it’s definitely time to retune your unit if you notice any discrepancies in the picture quality, see that the channels are out of order, or are presented with another region’s local news broadcast. 

If you’d like your tuning process to take as little time as possible, we recommend auto-tuning following the instructions outlined above. However, if it’s precision you’re going for, it’s best to manually tune it.
