When you hear crackling, clicking, or hissing on your television, you might be wondering, “Why does my TV make noise?” A few potential causes are: broken capacitors, improperly connected audio or video components, and Ground loops. Depending on the source of the noise, these problems may not be as simple as you might think. Read on to learn how to troubleshoot your television’s noise.
Broken capacitors
If your television is making noise, you might have a broken capacitor. Those small, orange or brown caps are responsible for all kinds of noise, from hissing to popping. If you’ve ever heard this noise, you know just how frustrating it can be. But you don’t have to spend hours searching online to find the problem. You can solve this issue yourself by following these simple steps. First, unplug your TV. If you can’t, consider replacing the TV.
To fix your television, first identify the part that has blown the capacitor. You can see it on the back panel of your television, between the input and power supply boards. You should then remove the back cover or section and check the circuit board. When the power LED turns on, the problem may be with the capacitor. If you can see the power LED, the capacitor is the cause of the noise. It is possible to replace the capacitor without spending more money on a new one. Otherwise, you can bring your television to a repair shop for further assistance.
While Samsung’s attorney cited 7.5 million TV sets as the class size, the actual number of TVs affected by this problem may be higher. Samsung’s attorney also mentioned that a simple replacement of the capacitor will cost between $150 and $129, depending on the model and the problem. But before you begin the repair process, be sure to check the model number to avoid getting an incorrect part. It’s easy to find the model number on the internet.
Improperly attached cables
It’s possible that your television is making noise due to improperly attached cables. First, you should check the connections. Check the coaxial cable. If it’s loose, it will make static noise when you turn it on. Then, you should check the connections of other TVs in the house. If they’re all fine, the problem is probably related to the incoming cable signal. If you’re experiencing static noise from multiple TVs, it’s time to call your cable provider.
Another possible cause is a game console or a DVD player. If the TV makes noise when it’s connected to these devices, the problem could be with the cables. Make sure that all the cables are securely attached to the device and to the TV. If the sound is still coming from these devices, you might need to replace them. Then, try to reconnect them. You should try all the steps one by one until you solve the problem completely.
If none of these solutions work, it’s time to contact the manufacturer of the device. If it’s a game console, check the controls and the audio settings. If you’re not sure which device is making the noise, try swapping it out. If the problem persists, check the settings of the connected device. If you still see noise, try switching to the internal speakers. If nothing else seems to help, try factory reset the device. If nothing seems to fix the problem, you can try checking for software updates and factory reset the TV.
Ground loops
If you’ve ever wondered how your TV can be making such a buzzing, hissing noise, or tearing sound, you may have a problem with a ground loop. The grounding points of your television and home theatre system are not the same, and this leads to a problem known as a ground loop. As a result, the coaxial cable entering your television and home theatre system are grounded to different points. Consequently, when the power is turned on, this loop causes a constant buzzing sound from the power source. The noise is consistent, whether you are watching your favorite show or tearing up your picture.
Often, ground loops are difficult to isolate, but there are some basic steps you can take to determine whether or not your system is experiencing this issue. First, try adjusting the level of the processor. Increasing or decreasing the volume of the processor may not change the hum level, but adjusting the receiver or processor volume may have no effect. If you have recently installed new components, the problem may be caused by a ground loop.
The problem may be an internal one. You’ll need to be skilled at appliance repair to diagnose the issue and fix it, but it’s a worthwhile exercise. If the noise is coming from the TV itself, you can power cycle it to rule out this possibility. Turn the TV off, connect the power cord, and try the device again. If this doesn’t help, call the cable/satellite provider to replace the equipment.
Improperly connected audio or video components
If you notice that the sound coming from your TV is intermittent, it might be a sign that one of the video or audio components is connected incorrectly. This can happen when you have connected a Blu-ray player or gaming console to your TV. Make sure to enable ARC on your TV before connecting it. If you still hear the noise, power cycling the television may fix the problem.
The most common cause for this problem is improperly connected audio and video components. A cable connected to the soundbar or the audio component is connected improperly and could be the culprit. Make sure to connect the two cables properly. This will improve audio quality. In addition, you should also make sure the TV’s audio cable is connected to the proper ports. If you can’t figure out the cause, you might want to check the content. If it’s not, the TV might be the culprit.
Improperly connected audio or video components can cause your television to buzz. Check the audio and video cables to the TV. If they aren’t connected correctly, the signals will interfere with the signal and make your TV make noise. If you don’t find any faults, you can contact your cable or satellite provider to replace the equipment. If you’ve tried all of these solutions, but still don’t hear the noise, check your connections.
Improperly connected speakers
If your television is making noise, it may be due to improperly connected speakers. Improperly connected speakers can cause a buzzing or humming sound. Ensure the cables are properly sized for the speaker channels, inputs, and outputs. Refer to the user manual for your specific speaker to determine the right cable size for the unit. If all of the above methods fail, you may need to consider purchasing an audio isolation transformer to reduce the noise. A transformer can be used to adjust the AC voltage and minimize buzzing.
If your TV makes noise when you switch on the volume, the most common cause is improperly connected speakers. All electrical devices produce a magnetic field when an electric current flows through them. Putting two or more gadgets too close to each other disrupts this field. Larger devices can pick up the interference and cause the TV to make noise. To avoid this, check your TV’s connection cables.
A TV can make popping sounds when the speakers are not properly connected. The problem is usually easy to solve, such as wriggling the speakers back into place. If this solution does not work, you can try changing the source of the TV. If the problem persists, try switching to a different source of audio, such as a streaming service or Blu-ray player. If the source is correct, the pops will disappear.
Improperly connected remote control
If your TV makes noise while watching a show, it may be due to the sound coming from a connected device. This could be an external device, such as a game console or DVD player. Incorrectly connecting a remote control may cause your television to make noise or even stop making any sound altogether. If you suspect that your remote control is the culprit, try resetting it or connecting it to another device. If none of these steps solves the problem, call a service technician to fix the problem.
If you have a Samsung 50-inch DLP Slim TV, you can try muting the speakers to stop the static noise. To do this, simply unplug the power cord and press mute+1+8+2+power to turn off the TV. Although I’m not sure what causes the static noise, I’ve tested this fix and it’s worked for me. Make sure to test all cables and connections regularly.
If the remote control is still making noise, check to make sure that it’s working properly. Check the emitter of the remote control with your mobile phone camera. If the remote is working, you should see a small red light when you press a button. If it doesn’t, the remote might be faulty or has dead batteries. If you’re not seeing a red light, then the infrared beam receptor of your television is probably covered with dust or other small objects.
