3 V TV LED strip repair LEDs – pre-soldered with adhesive

3 V LEDs for TV Backlight Strip Repair

Replace only the defective LEDs on a compatible backlight strip without necessarily replacing the entire strip. These 3 V LEDs come pre-soldered to wires and have adhesive on the back for easy installation.

This solution is particularly suitable when one or more LEDs have been clearly identified as defective using a backlight tester.

What are these LEDs used for?

• Repairing a TV LED strip with one or more failed LEDs
• Fixing a black screen with sound when the backlight is at fault
• Repairing dark areas or uneven lighting
• Avoiding the complete replacement of a strip when a targeted repair is appropriate

Specifications

• Voltage: 3 V
• Pre-soldered LEDs
• Adhesive on the back
• Designed for repairing compatible TV LED strips / bars
• Available packs: 7, 14, 21, or 70 LEDs

Compatibility: Must Be Checked

Before placing an order, compare the original LED with this model. Check the following in particular:

• the voltage of the original LED: 3 V
• its dimensions
• its polarity
• its mounting method

Warning: a 3 V LED is not suitable for a strip equipped with 6 V LEDs.

PiècesTV Tip Before Replacement

Ideally, test the entire strip before repairing. When one LED fails, other LEDs of the same age may already be weakened. For a long-lasting repair, check all the LEDs and replace several elements if necessary.

When to Use This Type of Repair?

This repair is appropriate when a specific LED has been identified as defective and the rest of the strip is still in good condition. Disassembling a TV panel remains a delicate operation: work on a flat, clean, and sufficiently large surface.
