How to Fix Blown TV Speakers
TV speakers are the sound systems that play high-quality sounds from your TV. Whenever you turn on your television, you will most likely hear the sound from its speakers. They can also be played directly with a variety of HDMI cables and audio input systems if there is no cable connection or for recording purposes. Unfortunately, sometimes these speakers get damaged for various reasons. For this reason, today, I will discuss a technique on how to fix blown TV speakers.
Types of TV Speakers
TV speakers are of different types and are available in two configurations; the front and rear speakers. The first type is a satellite (front) speaker that has a subwoofer. Satellite speakers are less expensive than loudspeakers, but they perform better than them. It comes with a tweeter and a woofer, from which sound originates. On the other hand, we have rear speakers that function as amplifiers for the satellite sound system. These speakers come with a woofer, tweeter, and three other speakers. They also have several ports that enable the smooth transmission of sound from one speaker to another.
How TV Speakers Gets Blown?
Most of the time, televisions are used for several hours a day. Some shows or movies are thunderous and require higher volume levels to enjoy the sounds.
Some people even turn up the TV louder if they want to hear something clearly. Unfortunately, it’s not always easy to find your remote control when you want to lower the volume level because it is hidden under piles of things on your couch. When you really need to grab that remote control quickly, you might accidentally press the power button and turn off your television!
A Process on How to Fix Blown TV Speakers
There are many reasons you may have blown speakers in your television. If you listen closely to the left and right speakers, you will notice that they are usually different in tone (i.e., one sounds lower than the other). This happens because there is only one speaker that produces both left and right audio from the television. This is why most televisions have blown speakers sooner or later, requiring replacement with new ones or a subwoofer system for better sound quality. The following steps describe how you can check if your TV’s blown speakers can be fixed on your own:
First, turn off all of the power to your home entertainment center so nothing can “blow up” while you’re doing this inspection! Then, unplug the TV (and the receiver if you have one) from both the wall and the surge protector. Once this is done, turn on your TV to an audio channel.
If you hear nothing or minimal sound coming from either of the speakers, it’s safe to assume that your speakers are blown. However, if you do hear a “papery” sound coming from both speakers, then there may be some hope for restoring them to their original condition. Therefore, take a headset (or headphones) and plug it into your home theater system so you can hear the “papery” sounds as well as any other random noise coming from each speaker individually.
Once everything is plugged in correctly and ready to go, play individual frequencies from 25 Hz to 15 kHz while listening for any loud, rattling, or “gurgling” sounds in each speaker. If you hear a deep “woofing” sound coming from the speakers rather than a high-pitched tone, it probably means that your audio system is blown and needs replacement. However, if you hear similar tones coming from both speakers at once, then they may be fixable after all!
If you decide to have your speakers repaired instead of replaced (or upgraded), here are some common methods you can use:
Use an Amplifier: Assuming that your home theater receiver does not have built-in preamps allowing for proper amplification of low-frequency sounds, the only way to fix blown TV speakers is with an external amplifier. This will allow for the crossover between low and high-frequency sounds coming from your audio system. Normally, you would have to contact an electronics technician to get new preamps installed into your home theater receiver, but this can be very expensive, depending on the amount of work needed.
If your speakers are still under warranty, then it’s probably best to let them deal with the problem rather than paying someone else hundreds of dollars for a repair job that can be done easily by you yourself!
Connect Another Subwoofer: Many people choose not to run whole-house speaker systems because they like the quality sound of their television better than anything else. However, if you’re serious about home entertainment, then it may be time for you to upgrade! A good subwoofer system will give you the full audio experience that your television is missing, all for the low price of around $300. There are many different types of subwoofer speakers available on the market today.
Precautions While Learning How to Fix Blown TV Speakers
- Always turn off your TV and remove the power source from it.
- Disconnect any other connected devices to your TV, such as gaming consoles, DVD players, or VCRs.
- Unplug all speakers from the back of your television set because they could be damaged during this process. Only one speaker should remain plugged in at all times. Never connect two or more speakers simultaneously to your television; otherwise, you will blow out the buzzer on each speaker, rendering it completely useless (as well as voiding its warranty). In addition, some speakers switch between internal and external connections; keep them in the external mode so that they are not accidentally damaged through possible accidental connections with other speakers or equipment during this process.
- Grab your multimeter and set it on reading resistance (Ohms). Touch the multimeter’s leads to the inside legs of each speaker’s two-wire connectors – one connector will have a red stripe, and one connector will have a black stripe. Note: Making sure that you are not touching anything metal is important; you could short your multimeter or blow a fuse in your house if you accidentally touch something metal at this point.
What Does a Blown TV Speaker Sound Like?
A blown speaker in a television produces a lot of interesting noises. However, it is important to distinguish between the harmless squealing sounds and the more problematic buzzing and rattle sounds since they require different fixes.
Squeals occur when some amplifier component (usually an output transistor) cannot deliver enough power to drive the speaker at its maximum voltage or current setting. This will produce a loud whistling sound that can damage your ears if you’re standing next to it while watching TV. Generally, this type of problem does not cause permanent damage to speakers but may cause them to fail prematurely due to overheating from excessive current flow.
How Much Does TV Speaker Repair Cost?
Let’s take a look at some of the common repairs that could need to be done to your television speakers. Two main parts make up a TV speaker: a woofer and tweeter, which both have their own power source and amplifier. If any one of these two-part fails, you will end up with blown TV speakers.
The average cost for TV speaker repair is around $200-$300. Of course, this can depend on what type of set you have and the size of either one or both speakers that have failed.
Lastly, I hope you will have a clear conception about how to fix blown TV speakers from this article. This will also provide sufficient knowledge about all the pertinent issues regarding TV speakers. Thank you and have a nice day!
