What Type of Home Theater Do You Have?

When it comes to understanding the different types of home theater systems, knowing the main components is key. Although the models vary by brand and personal preference, the main components of home theater systems include the following:

  • TVs and Projectors – Typically, options for home theater systems include LED, LCD, OLED, and plasma televisions. Projectors serve as an alternative to televisions, offering a much more cinematic experience with screens that pull down from a wall or ceiling mount.
  • Audio source – Audio in a home theater system can include sound bars, box systems, or systems built for individually chosen components. Building an audio system on your own provides the freedom to select specific features and choose an individual receiver for the system, but it may make wiring the system more difficult.
  • Video source – There are a couple of options when it comes to video in a home theater system. Some systems rely on Blu-ray or DVD players, as well as other video source components required to connect to the television and speakers. Other systems include standalone streaming players such as Apple TV and Roku, each of which have their own capabilities and compatibility requirements for equipment.
  • Receiver – Receivers work behind the scenes to process audio signals and send them through the speakers, producing sound. It is possible to set up some receivers to process video signals as well, which is helpful when using different video components with one television.
  • Connectivity – Home theater systems either connect through a series of wires, or they rely on wireless connectivity. Wireless connections make it easier to control the system through handheld devices and to add new speakers without worrying about additional wires.

Basic Types of Theater Audio Systems

The audio of a home theater system is one of the most important components, as it enhances the overall experience of enjoying a movie or film. To further understand which style of home theater system you have, consider the following types of audio systems:

  • Component systems – Component systems often include an audio and video (AV) receiver, as well as speakers and source modules like Blu-ray players. These systems may include sets of multimedia players or have wireless streaming capabilities from a standalone streaming source.
  • Component separates – Component separates are systems where a homeowner has replaced the theater system receiver with a different unit. This type includes theater systems that homeowners have built from individual components as well, creating a customized system.
  • Home-theater-in-a-box (HTIB) – Systems that fall into the home-theater-in-a-box (HTIB) category include full speaker and disc player units all in one package. Typically, these systems come equipped with surround sound speakers and a subwoofer, as well as all of the necessary wiring.
  • Sound bar – Sound bars are standalone audio units that homeowners can install to work with their existing systems. They may include a wireless subwoofer to complement the sound bar.

Common Home Theater Issues

During installation and after setup, you may come across some issues with your theater system. Common issues range from simple connectivity problems to equipment failure that requires parts and replacements. Here are some of the common problems and how much you might have to pay to get them fixed:

  • The system won't turn on – If nothing will turn on within the system, then there may be an issue with the power or cable connections. Calling an electrician for expert assistance may be necessary and can cost between $160 and $519 on average, depending on the scope of the wiring problem.
  • Poor picture quality – Poor picture quality may indicate that there is either a loose cable connection or that the cable is faulty. Swapping out the HDMI cable may improve the quality of the picture. Purchasing a new HDMI cable for a home theater system can cost from $5 up to $35 on average, depending on the type of cable.
  • No sound from speakers – If the speakers are not producing sound or the surround speakers are not functioning, it could be an issue with a poor connection or a damaged speaker. Test the speakers by playing different types of media that use surround sound effects or by going through the setup steps for your sound system's audio. If a speaker or a speaker system needs to be replaced, it can cost anywhere from $100 up to $3,000 based on the brand and size of the system.
  • Universal remote won't work – If a universal remote will not work, you should first check the batteries. If the batteries are rechargeable, they may have simply run out of power or gone bad. Otherwise, it might be an issue with a faulty remote. The cost to replace a remote varies, but typically you can spend anywhere from $30 to $100 on a new remote for a home theater system.
  • Projection lamp won't turn on – If the lamp in the projector will not turn on, then it most likely needs to be replaced. Typically, projectors feature an LED indicator light that flashes when the lamp has burned out, indicating that it needs to be replaced. Lamps that have been in use for over 1,000 hours will usually burn out or fail. Replacement lamps can cost from $30 up to $400 depending on the brand of projector.
  • Power failure after a power surge – Electrical problems during a storm or a power surge may wipe out a home theater system and cause issues with function. Purchasing a surge protector is a good way to prevent such a problem. Usually, the cost for a quality surge protector is $30 and up.
  • Frayed or worn wires and cables – Frayed or worn cables in a home theater system can cause many different kinds of connection issues. Fortunately, most wires and cables are easy to swap out. Depending on the brand and the length, wires and cables range from $10 up to $100.

Consider Upgrading to a Wireless Home Theater System

Repairs and replacements are sometimes a temporary fix for wiring and component issues in home theater systems. If you are struggling with keeping your home theater system running smoothly, then consider upgrading to a wireless system. Not only do wireless systems eliminate the need for keeping cords functional and tidy, but also they provide greater flexibility for homeowners who want to enjoy sounds from a variety of audio sources.

How Wireless Audio Systems Work

Wireless audio systems for home theaters play sound through Wi-Fi, Bluetooth, or Apple AirPlay. While it isn't necessary to set up a wireless audio system throughout the entire house, homeowners have the ability to do so if they choose. Depending on the brand, a wireless home theater system can cost anywhere from $50 to $3,000 and up, with mid-range wireless systems costing $250 to $500.

The setup process for wireless audio systems is typically very straightforward. During setup, homeowners guide the system through connecting to the desired wireless network following manufacturer instructions. Afterward, the system is simple to control using a remote, or through an app on a mobile device.

Benefits of Wireless Audio Systems

Wireless audio has many advantages when incorporated with home theater systems. Some of the benefits of wireless audio include the following:

  • They reduce cable and wire clutter around the home.
  • The speakers are easier to place around a room.
  • Installation and setup are both simple processes.
  • They have the same sound quality as classic speakers.
  • They can connect to a variety of handheld devices.
  • It is easy to add more speakers to the system later on.

Homeowners can also enjoy audio from supplementary sources such as satellite radio, which they may then transmit to wireless speakers around the home, or even outside.

DIY Home Theater Repair

When something goes wrong with a home theater system, trying to fix the problem on your own can save time and money. However, homeowners who have little to no experience working with electrical systems and wiring should always consult a licensed electrician to avoid the risk of injury and damage. Here are some tips for DIY home theater repair:

  • If a specific component or function will not work, unplug it temporarily to restart it. Plug it in and check the component's settings on the receiver, following the necessary steps to fix the issue.
  • To replace damaged, worn, or old wiring in a home theater system, begin by checking the wire's gauge so that you can purchase the right replacement wire. Avoid selecting speaker wire with a gauge thinner than 16, and instead choose a gauge between 12 and 16.
  • Measure to ensure you purchase the right amount of wire, and always maintain correct polarity when connecting new wires in a home theater system. Speaker wires in particular have red and black coloring to distinguish the two leads.
  • If possible, avoid splicing wires during replacements or upgrades. Splicing the wires in a home theater system may lower the performance of the various components. Using direct wire runs from the amplifier to the speakers will ensure that you get the best performance out of your system.
  • Labeling wires and cables during repair and installation is a good way to remember where new wires and cables need to connect. When installing new wires and cables, make sure to leave enough slack to move equipment around during and after installation.
  • When replacing a projector lamp, handle the new lamp with a microfiber cleaning cloth to keep it free of scratches and smudges. Carefully clean dust and debris from inside the projector after removing the old lamp, and properly connect power cables to the new lamp once it is inside the projector.

If a DIY home theater repair task seems too complicated, always consult a certified electrician instead of attempting it on your own.
