Symptoms
- Charging light or icon appears normally
- Phone vibrates or makes a boot sound
- Screen never lights up, even dimly
- May have followed a drop, water exposure, or been sitting unused a long time
Likely causes
- CommonVery low battery not yet able to power the displaySome phones show a charging indicator before there's enough charge to power the screen.
- CommonDisplay or backlight hardware failureThe battery and charging circuit can work fine while the screen itself has failed.
- PossibleLoose display connectorA drop can disconnect the screen while leaving the rest of the phone functional.
What to do
- Leave the phone plugged in and charging for at least 30–60 minutes before trying again, especially if the battery was fully dead.
- Try a force restart after the charging period.
- Try a different cable and charger to rule out a charging issue.
- Listen and feel for a startup vibration or sound when you try to power it on, which suggests the phone itself is running.
- Connect to a computer to see if it's recognized, which would confirm the system is alive.
- If there's still no display after charging and a restart, treat it as a likely screen hardware failure.
Tools and parts
