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
