Before you buy a full replacement kit, confirm that the backlight is actually the problem. Look for these signs:

If you can see a faint image on the screen when you shine a flashlight directly against the glass, but the screen is otherwise black, your JUQ470 strips have likely burnt out.

New strips prevent you from having to reopen the TV three months later when the next old strip fails.

LEDs degrade over time. If your screen suddenly looks cold, blue, or purple, the phosphor coating on the JUQ470 LEDs has failed.

When installing the new full kit, ensure the adhesive tape on the back is pressed firmly against the metal chassis to help draw heat away from the LEDs.

A "full" set usually refers to a complete array—often 8 to 12 individual strips—required to populate the entire backlight chassis of a specific TV model (commonly 40-inch to 55-inch displays from brands like Hisense, TCL, or Sharp). Common Symptoms of a Failing JUQ470 Strip

Always disassemble your TV first to verify the JUQ470 code printed on the actual strip. Manufacturers sometimes use different parts for the same model number.

Mixing old and new strips often results in uneven lighting or "hot spots."

Modern LED drivers work best when the resistance across all strips is identical. Installation and Specifications
