Why Does My TV Pixelate When It Rains?

Why Does My TV Pixelate When It Rains? – [Complete Guide]

TV signals may get affected by harsh environmental conditions like rain or snowfall. Rainfall is the leading cause of pixelation in TV screens. However, you cannot completely avoid this natural interference.

There are many reasons for the pixelated TV screen. When the rain droplets physically get contact with the satellite dishes it will cause scattering of signals. This will lead to your TV screen becoming blank.

Let’s find out the reasons behind TV screen pixelation and how to solve this problem.

Does Rain Affect TV Signals?

Yes, rain and humidity will affect the TV’s reception. Bad weather like high winds or snow can make your TV pixelated.

Apart from the fact that you are watching paid or free channels; rain affects it. Bad TV pixels are also common in digital TVs because digital TV is also affected by bad weather.

However, a soft rain shower does not affect the TV signals. But heavy rainfall, hail, or storms can. In this case, you will experience signal loss on your smart TVs.

Why Does Rain Pixelate The Smart TV?

Everyone wants to know why TV signals are affected by rain. As rainwater doesn’t get inside our homes or does not directly come into contact with TV, then what will be the reason?

Process Of Signal Interference:

The rainwater won’t contact your TV physically and interfere with the reception but still it can affect the TV signals. Fine raindrops can absorb some power from signals. Thus these raindrops will dissipate the signals and cause signal interference.

Let’s take an example; when a single light beam passes through a diamond it will lead to breaking the beam. Thus these smaller segments of light will bounce in multiple directions.

Rather than your TV signals passing straight into your smart TV, the rain droplets will cause the scattered signals. This can make your TV screen blank.

How To Solve The Poor TV Reception Issues Due To Bad Weather?

Many people experience bad TV signal issues in heavy rainfall. This issue is unavoidable. Let’s learn some ways to prevent or get rid of the pixelated TV screen.

Below are a few ways;

Solution – 1: Fix Your Satellite Dish Placement:

Usually, people do not think about the installation of satellite dishes. Satellite dish placement plays a huge role in signal interference. Specific locations of your home like near trees and leaves, or under the eave of your home can result in bad TV reception.

Because these areas drip water. This water is the biggest enemy of TV signals and causes much interference.

So you should try to change the location of the satellite dish to another place that should be dry. Additionally, you can also mount fiberglass in front of your dish to avoid water interference with TV signals.

Solution – 2: Get a Pre-Amplifier:

If you have more than one TV and you are using the same antenna for all the TVs, then you should need a signal splitter that will help to solve the signal reception problems.

When you don’t have a signal splitter with multiple TVs it shows every unit’s signals are very weak to create smooth and clear content. Thus a pre-amplifier will assist you in enhancing the TV signals and preventing TV reception issues.

Solution – 3: Get Better Aerial Antennas:

You should get an aerial antenna that can receive strong digital frequencies. You should do proper research and get help from the shop manager to discover which antenna can handle strong frequencies.

Furthermore, you can get help from a local cable technician to find out whether you need an antenna upgradation or not.

You should consider getting a better antenna when you are relocating your satellite dish, doing a home renovation, or getting the latest TV, which might affect your TV reception.

Solution – 4: Change Your Wiring:

One of the major reasons for bad TV reception during rain is loose or disconnected wiring. The wiring may disconnect or lose due to heavy rains, strong winds, or hail that will damage the wiring; thus it needs continuous maintenance.

To fix the bad signal issues, you should disconnect and reconnect the satellite cables to see whether it improves the bad reception issues or not.


In this article, you learned how rain and humidity affect TV signals. Yes, rain can affect your TV signal in multiple ways. When moisture or rain droplets are in contact with the satellite dishes, it will cause signal interference.

These issues are unavoidable but you can minimize them in multiple ways. You have to check your wiring or get a better antenna that will handle strong frequencies.

Hopefully, this guide will be helpful for you in solving interference issues.
