However, the buzzing noise in the Toshiba TV can be louder to a point it is alarming the users, reducing the state of discomfort to the user as it disrupts an individual’s mind.

Causes of the buzzing noise in a Toshiba TV

1. Starting the Toshiba television

The first place where a Toshiba television makes a buzzing noise is when the TV is turning on and when the TV is switching off. The buzzing noise results from electrical cables that expand and contract when they receive power making noise inside the television.  When the television receives power, it expands, and the other parts like the fan start compelling air, which is a source of noise in the TV.

Buzzing noise when starting the TV and switching it off is normal since it must make a buzzing noise to confirm it is working. Therefore you must not worry when the TV is making a buzzing noise when starting or when switching.

2. Dirty particles are accumulating in air vents

Dirty particles accumulate in the air vents blocking the vents such that they cannot allow cool air to flow inside and warm air outside, making the  TV produce a buzzing noise when the air is straining to pass into the system.  Sometimes the fan will make a buzzing noise as it works hard to pass air that ends up passing through the air vents. A straining fan will always make a buzzing noise in the Toshiba TV when circulating air in and out of the system.

To reduce the buzzing noise in the Toshiba TV, it is good to clean the dirty particles by wiping dust that accumulates and picking the other debris using fingers. Always use a piece of cloth or cotton wool to wipe the dust from the air vents. Failure to clean the air vents increases the buzzing noise in the TV and can lead to more damage in the TV that cannot give you peace when using the television for entertainment.

3. Fixing the Toshiba television on hard surfaces

When you install the Toshiba TV on hard surfaces like the glass surface, wall brackets, or wooden surfaces, loud buzzing noise that affects the user’s daily operations can keep worrying about what to do.  The noise results from vibrations that occur when the Toshiba TV is starting due to the expansion of cables and other components in the TV.  The hard surfaces do not tightly hold the TV due to their complex nature that causes the television to make a loud buzzing noise when running.

Therefore, use soft and spongy surfaces to fix the Toshiba TV to reduce the buzzing noise. It helps the television stick to the surface and cannot move when it is vibrating.  The spongy surfaces include rubber surfaces that provide a stable place to set the television and hold it firmly.

4. Connecting the TV with external speakers

Connecting the TV with external speakers

Most people connect their televisions with external speakers to increase their TV volume, which can cause the production of the buzzing noise in the TV through the cables that are there for connection. The noise through the cables results from a loose connection between the TV and the speaker. In a case like connecting the television with the speaker when the link between them is open causes some buzzing noise that when you use the connection for long leads to loud buzzing noise.

Therefore, it is good to avoid connecting the external devices to the television, or when they need for connection arises, ensure the connection between the two devices is tight to reduce the noise.

5. Faulty power cables

Faulty power cables

Power cables in the Toshiba television help connect the television to the power supply to provide energy for the TV parts to start working. However, when the wires are faulty, they will provide less energy, or sometimes they fail to deliver fuel to the television. The less power in the Toshiba television causes the television to start and occasionally stop, which can be a continuous process, causing the buzzing noise now and then.

With any case of faulty power cables and other cables, replacing the cables immediately as failure to replace them can cause greater damage to the whole system.
