What are LED strips?

LED strips are the light source behind the LCD screen in LED TVs (yes, the screen is still LCD). These strips get their power from the LED driver or the power supply board and control the image brightness on your TV screen.

Which symptoms do LED strips fix in a TV?

• If you see very dim video or no video on the screen, but you know your TV has power and is on, then the LED strips could be bad.

• If you see very dim video or no video on only a portion of the screen while the rest of the screen is bright/normal, then the LED strips could be bad.

*These are helpful tips to get you started and don’t represent accurate diagnoses for every TV model and failure. If you’re unsure of your diagnosis, we recommend checking out our YouTube channel or reaching out to a local TV technician for assistance.

How easy is it to replace LED strips?

While replacing your LED strips isn’t hard, you’ll need to be careful when tearing down your screen assembly to access them. We recommend following our video tutorials on YouTube and taking your time.

We recommend matching the part number on your original part with the part number listed on this page to ensure compatibility.

While matching your model number is a great start, many models use variations of each part and they're not always interchangeable.

We include brief instructions in red text on some listings (also displayed below without the red font). Please look for these instructions to confirm any important info that you'll need to identify on your original part. Additionally, we highlight the part number in our photos.

Please don't hesitate to contact us with any questions. We're here to help!
