The Home Theater, TV & Video collection brings together TV replacement parts, home theater replacement parts, accessories, and components for televisions and related video equipment. At Genuine Replacement Parts, you can find replacement components such as mainboards, T-Con boards, power supply boards, LED backlight strips, stands, wall mounts, remote controls, IR sensors, speakers, cables, connectors, fans, and other electronic and mechanical parts. Match your equipment model number and existing part number to find the correct replacement part for your repair.
Common TV and home theater repairs involve mainboards, control boards, T-Con boards, power supply boards, LED backlight components, remote controls, IR sensors, speakers, subwoofers, cables, connectors, fans, stands, mounts, brackets, and other replacement components. These parts should be selected by model number because televisions and home theater systems that look similar can use different connectors, board revisions, mounting points, dimensions, or component configurations.
How to Find the Right TV or Home Theater Replacement Part
Your equipment model number is one of the most important details when looking for a TV or home theater replacement part. For televisions, the model label is commonly located on the back of the unit, on the side or rear panel, or in the original documentation. For home theater equipment, check the rear, bottom, or side of the component for the model and serial information.
Search using the complete model number first, then narrow the results by part type or component number. A TV that will not power on may require a power supply board or mainboard. A display problem may involve a T-Con board, LED backlight component, or another display-related part. A home theater system with missing audio may require a speaker, subwoofer, cable, amplifier-related component, or control board. Matching the exact model and existing part number is more reliable than selecting a replacement component only because it looks similar.

What TV and Home Theater Parts Are Commonly Replaced?
TV and home theater owners replace parts for both simple accessory needs and more advanced electronic repairs. Common replacements include components responsible for power, display processing, illumination, audio, control, cooling, connections, and equipment support. Instead of replacing a component based only on a symptom, identify the equipment model and inspect the related components so the replacement matches the original configuration.

How to Choose the Right TV or Home Theater Replacement Part
Start with the complete brand and model number of the television or home theater equipment. Then identify the exact component and compare the existing part number, connector type, mounting points, dimensions, and visible design. Model-based matching is more reliable than selecting an item only because it looks similar.
TV and home theater repairs can range from simple external replacements to advanced electronic component work. A television with a blank screen, for example, may have a power, backlight, signal-processing, or panel-related issue. Likewise, a home theater system with missing audio may require inspection of speakers, amplifiers, cables, or control components. Identify the equipment type, brand, model number, and symptom before selecting a replacement part.
Repair and Safety Notes Before Replacing TV or Home Theater Parts
Disconnect electrical power before opening a television, home theater component, or other electronic equipment. Internal boards, power supplies, capacitors, and display components can present electrical hazards even after the equipment has been switched off. For advanced electronic repairs, use appropriate service documentation and qualified repair support.
Do not force a connector, screw, bracket, stand, or board into position if it does not match. Confirm the model, part number, connector arrangement, mounting points, and dimensions before installation. For wall mounting, use hardware rated for the equipment and the intended mounting surface.
How to Order the Right Part from Genuine Replacement Parts
Start with the exact model number, then search the part name, symptom, or existing component number on Genuine Replacement Parts. Once the matching product appears, compare the product image, connector style, dimensions, mounting points, and compatibility information before ordering. This is especially important for circuit boards, power supply boards, display-related components, remote controls, speakers, and mounting hardware because small model differences can affect fit and compatibility.
If you are replacing more than one component, inspect related parts during the same repair. For example, a TV that will not power on may require inspection of the power supply and mainboard, a display problem may involve the backlight and display electronics, and missing home theater audio may require checking speakers, cables, and control components before the replacement is installed.
