How to find the right LED strip model for your TV?

You need to replace your TV's backlight, but you don't know which LED strips to order? Warning: knowing only the TV brand and model is not always enough.

The same TV model can be equipped with several versions of LED strips. To avoid ordering the wrong part, it is important to identify the original part numbers and compare the specifications of the replacement kit.

Key takeaway: the part number printed on the original LED strips and their technical specifications are often more reliable than the TV model number alone.

1. Record the TV's full model number

Start by checking the label located on the back of your TV. You will generally find the brand, model number, and sometimes a product code or version.

  • LG: 65UJ634V
  • Samsung: UE75RU7100
  • Philips: full model and product code
  • Sony: part number starting with KD or KDL, depending on the generation
  • TCL: model and possible product version

Copy down all available information. A change in suffix or version can sometimes correspond to a different configuration.

2. Identify the part number printed on the LED strips

The most reliable method is to record the markings directly on the original backlight strips. These part numbers are generally printed on the circuit board, sometimes accompanied by a revision number or manufacturing date.

LG Example: SSC_65UJ63

On some 65-inch LG configurations, you may find the markings SSC_65UJ63 and LG Innotek 17Y 65Inch.

Samsung Example: STS750A26

The part number STS750A26 is associated with a kit offered for several 75-inch Samsung TVs, including the UE75RU7100 and UE75NU7100.

These examples show how to identify a part number. They do not replace the need to check the specifications of the strips already installed in your TV.

3. Check the kit specifications

Two LED strips that look identical in a photograph are not necessarily interchangeable. Before ordering, check each point below.

  • Strip length: a difference in length may prevent installation in the chassis.
  • Number and arrangement of LEDs: compare their quantity, spacing, and placement on each strip.
  • Connectors: check their type, number of contacts, location, and wiring.
  • Electrical specifications: some strips use 3 V or 6 V LEDs, for example. An LED's voltage should not be confused with that of the entire strip.
  • Number of strips and revisions: make sure the kit includes all the necessary bars and matches the original version.

4. Why is the TV model not enough?

Manufacturers may use different LCD panel or backlight part numbers during the production of the same series. Two TVs with the same model number may therefore require different kits.

Always compare the part number printed on the original strips, the photographs, and the product specifications rather than relying solely on a list of compatible models.

5. Do you need to disassemble the TV to find the part number?

The exact part number of the LED strips is generally only visible after removing the panel and diffusion elements. This operation requires great care: large LCD panels are particularly fragile and can crack if mishandled.

Important precaution: always unplug the TV before performing any work. Some internal components may retain a dangerous voltage even after being unplugged. If you are not experienced in disassembly, call a repair technician.

6. Check the fault before ordering

A black screen does not automatically mean that the LED strips are defective. If your TV still produces sound, the backlight is one of the elements to examine, but the backlight power supply or another circuit may also be at fault.

7. Where to buy compatible LED strips?

Once the part number has been identified and the fault confirmed, look for a kit that matches the original specifications. PiècesTV offers backlight LED strips for many TV brands, including Samsung, LG, Philips, Sony, and TCL.

Frequently Asked Questions

Can you replace only a defective LED?

This is technically possible in some cases, but replacing the entire set of strips is generally preferable. The other LEDs have often undergone comparable wear.

Are LED strips of the same length compatible?

No. Length is only one criterion. The part numbers, number of LEDs, electrical specifications, connectors, and revisions must also match.

Can you order using only your TV model?

The model allows you to start your search, but confirming the original strip part number is still preferable.

In summary: record the TV's full model number, identify the original strip part number, and compare the technical specifications before ordering. This will limit compatibility errors and unnecessary disassembly.
