The problem can also be an internal fault so keep that in mind. Read on.
Why is my TCL TV making a Distortion Sound?
Your TCL TV is making a distortion sound because there is an interference of external device, TV is put on uneven surface, or there are ventilation issues.
TVs are made with a combination of metal and plastic material.
These things are subject to expansion and contraction due to temperature changes around them.
An occasional creaking, popping, or cracking can be heard. Keeping this in mind, here are a few steps on how to reduce the expansion that can cause these noises.
Ideally, the only buzz your TCL TV should produce is a navigation sound or something about what’s on the screen, unlike the cathode ray tube televisions of the past, LCDs do not naturally hum, even ever so slightly.
Multiple problems, including external factors and internal device issues, can cause buzzing.
To fix these problems, start with easy solutions, before calling Customer Support and repair technicians.
Fix: TCL TV Sound Distortion, Crackling, Popping sound
Hearing distortion, cracking or popping noises after you turn off the TV can be distressing.
However, these sounds can be completely harmless and may not affect the TV. Here are a few methods to help fix this from happening.
Method 1: Ensure Ventilation
Make sure that there is enough ventilation. Some devices may not provide proper ventilation.
This causes the internal temperature to rise and the plastic inside to expand even more than normal. For recommended ventilation requirements, please see your user manual of your TV
Method 2: Check for nearby appliances
Make sure there isn’t any heater or air conditioning vent pointed directly at the TV.
Method 3: Check for uneven surfaces
Make sure that the TV is on a flat and level surface. Tilting it or keeping it on an uneven stand can also cause these noises.
The only noise you should hear from your television is the sound of what you’re watching.
A buzzing, crackling, or humming noise could also be caused by an electrical current. Arranging the power cables or any other cables and making sure the TV has good ventilation will keep it quiet.
How to Fix TCL TV making Buzzing Sound
Method 1: Check the inputs
Mute your TCL TV and listen closely. If the buzz stops when you mute the TV, the issue is likely audio or software-related.
In this case, check all of your TV’s external audio connections. Make sure that all the cables are securely plugged into their own inputs.
Method 2: Change external device audio settings
Toggle the volume settings on external devices connected to the TV, if they exist.
Some devices, such as set-top boxes, sound bars and DVD or Blu-ray players, feature their own volume control settings. If the volume on these connected devices is too high, your TV may buzz when it’s on.
Turn off the TV, then unplug it from the power outlet.
Let the device rest for at least 60 seconds before plugging it back in and powering it on. This may help the buzzing related to the TV.
Method 3: Remove interference
Move electronic devices that can cause interference away from your TCL TV.
Devices such as microwaves, power generators, hair dryers, sewing machines, electric drills, and vacuum cleaners can produce electrical interference while operating, causing your TV to emit buzzing sounds.
Method 4: Lower brightness settings
Lower your TV’s brightness settings. The capacitors that supply power to your LCD TV’s fluorescent backlight can emit an unintentional buzz.
Lower the brightness and backlight settings of your TCL TV via the TV menu. See if it fixes the problem.
