Buying a new television is only the beginning of building a good home entertainment system. The accessories connected to your TV can affect sound quality, streaming performance, gaming, connectivity, convenience, and even how well your electronics are protected from electrical damage.
The problem is that there are hundreds of TV accessories available, and many of them are marketed as if they are absolutely necessary. They are not!
Some accessories can dramatically improve your setup. Others only make sense for certain TVs or viewing habits. A few, particularly electrical protection devices, can potentially help prevent the type of damage that eventually leads to a TV repair.
At TVpartsToday, The World's #1 Hub for DIY TV Repair, we spend most of our time helping people diagnose broken televisions and find the correct replacement circuit boards. That experience also gives us a useful perspective on something equally important: protecting your television and building a setup that works properly in the first place.
So, what accessories do you actually need for your TV? Let's look at the ones that provide the most practical value!

A Quality Surge Protector Should Be Near the Top of Your List
If we could recommend one accessory for almost every television setup, it would be a quality surge protector. Modern televisions contain sensitive electronics including a power supply board, main board, processors, memory, voltage regulators, and numerous other components that depend on stable electrical power.
A sudden voltage spike can damage those components. Lightning is one possible source, but electrical disturbances can also occur because of utility problems, power restoration after an outage, switching events, or electrical issues elsewhere in the home.
The power supply board is particularly vulnerable when excess voltage enters through the TV's power connection. Depending on the severity and path of the surge, other components can be damaged as well.
A good surge protector provides an additional layer of protection between your television and the electrical outlet. Look for a reputable surge protector with an appropriate joule rating and recognized electrical safety certification rather than simply choosing the cheapest power strip available.
There is also an important distinction between a power strip and a surge protector. A basic power strip primarily gives you additional outlets. It does not necessarily provide meaningful surge protection.
TVpartsToday Tip: Do not assume that something protects your TV from surges simply because it has six outlets and an illuminated power switch. Confirm that the product is actually designed and certified for surge protection.
Protect the Devices Connected to Your TV Too
This is one of the most overlooked parts of protecting a home entertainment system. A damaging electrical surge does not necessarily have to enter your television through its power cord. Voltage can potentially reach the TV through connected equipment and communication cables.
A cable box, satellite receiver, gaming console, streaming device, sound system, or other connected electronics can provide another route into the television. In severe surge events, damage can reach HDMI ports and the main board through these connections. That means plugging the TV into a surge protector while leaving every connected device completely unprotected does not necessarily protect the entire system.
Whenever practical, think about surge protection as protection for your entertainment system rather than just protection for one television. During a severe thunderstorm, physically unplugging valuable electronics provides another level of protection. No consumer surge protector should be considered an absolute guarantee against a direct or extremely powerful lightning event.
For homeowners who experience frequent electrical disturbances, whole home surge protection installed by a qualified electrician can provide another layer of defense.
Do You Need a Soundbar for Your TV?
A soundbar is one of the accessories most likely to produce an immediately noticeable improvement. Modern televisions have become remarkably thin. That is excellent for appearance and wall mounting, but extremely thin cabinets leave limited space for large speakers.
As a result, you may have excellent 4K picture quality while voices sound thin, dialogue is difficult to understand, or movies lack the impact you expected. A soundbar can improve dialogue clarity, volume, stereo separation, and bass response without requiring a complicated surround sound installation.
When choosing one, first check which audio connections your television supports. HDMI ARC or eARC can simplify the setup because compatible televisions can send audio through an HDMI connection while allowing certain volume and power functions to work together.
Optical audio is another common option. Bluetooth can be convenient for wireless audio, although wired HDMI ARC or eARC connections are generally preferable when the television and soundbar support them. Before buying anything, verify the ports available on both devices.
TV Has No Sound Through the Soundbar? Check the Settings Before Assuming Something Is Broken
Adding accessories also creates additional troubleshooting variables. If your soundbar suddenly stops producing audio, that does not automatically mean the television or soundbar has failed.
Check the TV's audio output settings first. Confirm that the correct HDMI ARC or eARC port is being used. Make sure the cable is fully connected. Verify that the soundbar is on the correct input. You can also disconnect the soundbar temporarily and test the television's internal speakers.
If the internal speakers work normally, you have immediately narrowed the problem toward the external audio setup rather than the television's entire audio system. Simple isolation tests like this are the same type of process of elimination we recommend during DIY TV repair.
Streaming Devices Can Give an Older Smart TV a Second Life
If your television still has a good picture but its built in Smart TV software has become slow or outdated, you may not need a new television. An external streaming device can be an excellent upgrade.
Devices from platforms such as Roku, Amazon Fire TV, Google TV, and Apple TV can provide newer applications and a faster interface than the software built into some older Smart TVs. This is especially useful when manufacturers stop supporting applications or firmware on older televisions.
Before choosing a streaming device, consider your television's capabilities. If you have a 4K TV and want 4K content, choose a device that supports 4K output. If your television supports HDR formats you intend to use, verify compatibility with those formats as well.
For an older 1080p television, purchasing the most expensive 4K streaming device may provide features you cannot fully use. Match the accessory to the TV rather than simply buying the most expensive version.
Do Expensive HDMI Cables Improve Picture Quality?
HDMI cable marketing can become confusing very quickly. For a normal digital connection, spending a huge amount of money on an HDMI cable does not automatically make the picture sharper, more colorful, or more detailed.
What matters is using a cable capable of supporting the bandwidth and features required by your equipment. A basic streaming setup has different requirements than a modern gaming console running high resolution content at high refresh rates.
If you are connecting newer gaming equipment, an advanced receiver, or devices that depend on features associated with HDMI 2.1, make sure the cable is certified for the required bandwidth. For ordinary devices, however, there is little reason to assume that an extremely expensive cable will produce a magically better picture simply because it costs more.
Cable length also matters. Purchase a cable long enough to reach comfortably without creating tension on the HDMI ports, but avoid unnecessary lengths when they provide no benefit.
TVpartsToday Tip: Before assuming you have a bad HDMI port or main board, test another HDMI cable and another input. A defective or improperly connected cable is much easier and less expensive to eliminate than an internal TV component.
Why HDMI Accessories Matter During TV Troubleshooting
HDMI devices are worth discussing for another reason. They can sometimes make a perfectly functional television appear defective. Imagine your game console displays a black screen.
Is the TV broken?
Maybe, but there are several things to test first.
Try another HDMI cable. Try another HDMI input. Connect a different device to the same port. Restart both devices. Verify that the external device is outputting a resolution and refresh rate the television supports.
If every HDMI device fails on every input while the television's built in menus and streaming applications continue working normally, the HDMI circuitry on the main board becomes more suspicious.
On the other hand, if replacing a five dollar cable solves the problem, you have avoided an unnecessary TV repair. This is why troubleshooting external accessories should happen before opening the television.
Ambient Lighting Can Improve the Viewing Environment
Bias lighting or ambient lighting behind a television has become increasingly popular. These lighting systems place a soft source of light behind or around the TV rather than shining directly toward the viewer. For many people, this can make watching television in a dark room more comfortable while also creating a more dramatic entertainment setup.
Simple bias lighting kits provide a consistent glow behind the television. More advanced smart lighting systems can integrate with other home automation products or change colors based on user settings. The important factors are proper placement and brightness.
Ambient lighting should complement the screen rather than overpower it. If the wall behind the TV is glowing so brightly that it distracts you from the picture, the lighting is working against the viewing experience rather than improving it.
Is a Blu Ray Player Still Worth Buying?
Streaming dominates modern home entertainment, but physical media still has advantages. A Blu Ray or Ultra HD Blu Ray player can be worthwhile for viewers who prioritize consistent picture quality, high quality audio, physical ownership, or access to movies and bonus features that may disappear from streaming services.
Physical discs also do not depend on your internet connection. If your home has inconsistent broadband performance, a disc can provide reliable playback without buffering or sudden quality reductions. For most casual viewers, streaming may be sufficient. For movie enthusiasts with high quality TVs and audio systems, physical media can still have a place.
Wireless Headphones Are Useful for Private TV Watching
Wireless headphones can solve a very specific problem extremely well: watching television without disturbing anyone else. They can be particularly useful for late night viewing, shared living spaces, gaming, or situations where clearer dialogue is desired without dramatically increasing the television's volume.
If your television has built in Bluetooth audio support, pairing compatible headphones may be straightforward. If Bluetooth is unavailable, an external transmitter may provide another option depending on the TV's available audio outputs.
Before purchasing wireless headphones specifically for television use, verify how the TV handles Bluetooth audio and whether it supports the type of device you intend to connect. Also consider latency! A noticeable delay between someone's lips moving and the sound reaching your headphones can be distracting, so compatibility matters for video use.
Gaming Accessories Depend on How You Use Your TV
For a television connected to a PlayStation, Xbox, Nintendo system, or gaming PC, the most important accessories are not necessarily the flashy ones. Start with connectivity.
Make sure your HDMI cable and television input support the resolution, refresh rate, HDR features, and other capabilities you want to use. A gaming headset can improve communication and provide private audio. Controller charging stations can keep equipment organized and ready. Comfortable seating can make long gaming sessions more enjoyable.
But none of those accessories can compensate for an incorrectly configured television. Check whether your TV has a Game Mode or low latency picture mode. If supported, review settings related to refresh rate, variable refresh rate, HDR, and HDMI input configuration. Sometimes the best gaming upgrade costs nothing more than configuring the television correctly.
Cable Management Is More Important Than It Looks
Cable management is usually discussed as an appearance issue, but it can also protect your equipment. HDMI and power cables should have enough slack that they are not pulling against the television's connectors.
This becomes especially important with wall mounted TVs. A heavy cable hanging at an awkward angle can place unnecessary stress on an HDMI port. Cables crushed behind furniture or sharply bent around a wall mount can also develop problems over time.
Organize cables so they have a natural path between devices without excessive tension. It makes the setup look cleaner and makes troubleshooting significantly easier when you eventually need to determine which cable connects to which device.
Wall Mounts Need to Match the Television
Wall mounting can create a clean entertainment setup and free up furniture space, but the mount must be appropriate for the television.
Check the TV's weight, screen size, and VESA mounting pattern before purchasing a mount. The mounting hardware also needs to be properly secured to a suitable wall structure.
This is one accessory where guessing is a bad idea. A television falling from a wall does not create the type of damage that can usually be solved with a replacement circuit board. A cracked display panel generally means replacing the entire television because screen replacement is rarely economical. Protect the physical TV just as carefully as you protect its electronics.
Ventilation Is a Free TV Accessory
Technically, ventilation is not something you buy, but it deserves a place on this list because it can affect the longevity of your television and connected devices. Modern Smart TVs contain processors, power electronics, voltage regulators, and other components that produce heat.
Do not completely block the ventilation openings around the TV. If the television sits inside an entertainment cabinet, make sure warm air has somewhere to escape. The same principle applies to game consoles, receivers, streaming boxes, and other electronics.
Periodically remove excessive dust from the area around your entertainment system as well. Keeping electronics cool and properly ventilated is one of the simplest ways to create a healthier operating environment.
What Are the Most Important TV Accessories?
If you are starting from scratch, you do not need to purchase everything at once. Prioritize accessories according to the problems you actually need to solve. For protection, start with a quality surge protector. For weak television audio, consider a soundbar.
For an older or frustrating Smart TV interface, consider an external streaming device. For gaming, verify that your HDMI connection supports the features your console and television can actually use. For private listening, wireless headphones may be valuable.
For atmosphere and viewing comfort, bias lighting can be a worthwhile addition. The best accessory is not necessarily the most expensive one. It is the accessory that solves a real problem in your particular entertainment setup.
Accessories Can Also Help Diagnose TV Problems
There is another reason DIY repairers should understand their accessories. Every device connected to a television introduces another possible point of failure. A bad HDMI cable can resemble a failed HDMI port. A malfunctioning streaming device can make it appear that the TV is freezing.
Incorrect soundbar settings can resemble an audio failure. A weak Wi Fi connection can make a Smart TV appear slow or defective. A damaged external device can even contribute to electrical problems. Before assuming that an internal circuit board has failed, disconnect unnecessary accessories and test the television by itself whenever possible.
Then reconnect devices one at a time. This simple process of elimination can tell you whether the problem follows an accessory or remains with the television.
What If the TV Really Is Broken?
Accessories can improve and protect a television, but eventually a TV may develop an actual hardware failure. If that happens, do not immediately assume you need a new television. Many common failures originate from replaceable internal circuit boards.
A TV that will not turn on may have a power supply problem. Failed HDMI inputs, boot loops, Smart TV problems, or widespread system failures can point toward the main board. Certain picture problems may involve the T Con board on televisions equipped with a separate T Con.
The key is diagnosing the symptoms first and replacing parts second. When you do need a replacement circuit board, identify it using the exact manufacturer part number whenever possible rather than relying solely on the TV model number or a number printed directly on the PCB. The same TV model can contain different board revisions, making exact part identification essential.
Build a Better Entertainment Setup and Protect It
The best home entertainment setup is not the one with the most accessories. It is the one where every component has a purpose.
A surge protector helps defend your electronics from damaging voltage spikes. A soundbar addresses weak built in television audio. The right streaming device can modernize an older Smart TV. Proper HDMI cables allow your devices to use the capabilities they were designed for. Wireless headphones, bias lighting, gaming accessories, and physical media players can then be added according to how you actually use your television.
Just as importantly, understanding your accessories makes troubleshooting easier. When something stops working, you can isolate the television from connected devices, test cables and inputs, and determine whether you have an accessory problem or an actual internal TV failure.
