Likely causes
- CommonBacklight failureThe display panel can fail to light up while the touch layer and rest of the phone keep working.
- CommonFull software crash or boot loopA frozen operating system can leave sound working briefly while the display never initializes.
- CommonLoose or damaged display connectorPhysical impact can disconnect the cable feeding the screen without damaging the rest of the phone.
- PossibleBattery or power delivery issueInsufficient power to the display circuit can leave everything else running but the screen dark.
What to do
- Force restart the phone using your model's button combination; keep it held for a full 10–20 seconds.
- Plug the phone into a charger and wait 15–30 minutes in case the battery is too low to power the display specifically.
- Connect the phone to a computer to see if it's still recognized, which confirms the main system is alive.
- Try connecting to an external display via any supported cast or mirroring feature if your model supports it, to check if the phone's video output works at all.
- Avoid repeatedly restarting many times in a row, which can drain the battery further.
- If the phone was recently dropped or got wet, treat this as likely hardware damage.
- Back up data through a computer connection if the phone is still recognized but the screen stays dark.
