Fix the Samsung Galaxy A13 (A135F) display backlight issue with tested hardware and software solutions. Follow step-by-step repair guidance.

If your Samsung A13 (model A135F) shows signs of a working display (like sound, vibration, or notification light) but the screen remains dark or very dim, you are likely facing a backlight issue. This is usually due to:

A faulty backlight LED or display panel

Damaged display connector or loose flex cable

Burnt or shorted backlight filter/coil

Faulty PMIC (Power Management IC) or backlight IC

Software/firmware glitch (in rare cases)
🔧 Hardware Solution:

1. Check the Display:

Replace the display with a known-good one to rule out LCD damage.
2. Inspect the Display Connector:

Clean the display flex and connector with isopropyl alcohol.

Look for any signs of corrosion or physical damage.
3. Check Backlight Components:

Locate and test the backlight filter, coil, and diodes using a multimeter.

If faulty, replace with the same rated components.
4. Check Backlight IC (if applicable):

If the coil and filters are fine but still no light, suspect the backlight IC.

Reball or replace the IC as needed
