This next-gen, technician-tested guide reveals the exact display light jumper repair method for Vivo Y12 units that power on but show no backlight. Includes clear diagrams, pro soldering tips, and safety steps.

Problem Summary

The Vivo Y12 can turn on but stay dark because of a damaged backlight track. A simple jumper repair reconnects the broken line between the display connector and the backlight power source.

Step-by-Step Repair

1. Check voltage at the backlight pin using a multimeter.
2. If no voltage, clean pads and prepare the jumper points.
3. Solder a fine jumper wire between the display pin and the source pad.
4. Secure the jumper with tape or UV glue.
5. Test the phone before full assembly.

Precautions

• Use thin enameled wire to avoid pad damage.
• Never bypass if the backlight IC is shorted.
• Always protect jumper wires to prevent breaks.

Note: This repair is for experienced technicians only. Improper soldering can cause more damage.
