Phone screen is black but the phone is still on.
You can hear notifications, feel vibrations, maybe even receive calls — but the screen shows nothing. This is different from a dead phone. Your phone is alive; the display just isn't working. Here's how to figure out why and what it costs to fix.
First: try a force restart
In rare cases, a software crash can freeze the display while the phone continues running in the background. A force restart clears this. iPhone: quick-press Volume Up, quick-press Volume Down, hold Side button 10–15 seconds. Samsung/Pixel: hold Power + Volume Down 10–15 seconds. If the screen comes back, it was a one-off crash — no repair needed.
If the force restart didn't help — diagnosis
Cause 1: Disconnected display cable (cheapest fix)
A drop can partially dislodge the flat flex cable that connects the screen to the logic board. The screen hardware is fine — it's just not plugged in properly. Signs: the phone was dropped recently, the screen was working fine before the drop, there's no visible damage to the glass. Fix: a technician opens the phone and reseats the cable. Cost: $0–$39 (diagnostic fee, often free if you get the repair done at the same shop). Takes 15 minutes.
Cause 2: Dead OLED/LCD panel (most common)
The display panel itself has failed — either from impact damage (even without a visible crack), pressure damage (sat on the phone, heavy bag), or component failure. Signs: no light from the screen at all (hold the phone in a dark room and look for any faint glow), phone vibrates and makes sounds normally. Fix: full screen replacement. Cost: $109–$619 depending on model.
Cause 3: Display IC failure on logic board (expensive)
The display driver IC (the chip on the logic board that sends image data to the screen) has failed. The screen is fine, the cable is connected, but the board isn't sending a signal. Signs: a new screen doesn't fix the problem (the shop tries a known-good screen and it's still black). Fix: board-level micro-soldering to replace the display IC. Cost: $149–$399. Not all shops offer this.
Cause 4: Water damage (hidden)
Moisture corrosion on the display connector or backlight circuit can cause a black screen with no other visible symptoms. Signs: the phone was exposed to moisture (even humidity, not just submersion), or there's condensation visible inside the camera lens. Fix: ultrasonic cleaning ($49–$99) plus screen replacement if the panel is damaged. See our water damage guide.
How to save your data first
If the phone is on but the screen is black, your data is almost certainly intact. Here's how to access it:
iPhone + Mac/PC: Connect via USB cable. Open iTunes (Windows) or Finder (Mac). If you've previously trusted this computer, it can back up the phone even with a black screen. If you haven't trusted the computer before, you'll need the screen working to tap "Trust" — a repair shop can connect a temporary screen to do this.
Android + PC: Connect via USB. If USB debugging was enabled, you can access files via ADB or file transfer mode. If not, some Android phones enter file transfer mode automatically when connected — check if the computer recognises a new storage device.
Either platform: If the phone has wireless backup enabled (iCloud, Google Drive), your data is likely already backed up to the cloud. Check from another device or a browser.
What the repair costs
Cable reseat: $0–$39 (diagnostic fee). The cheapest possible fix — worth checking first before committing to a screen replacement.
Screen replacement: $109–$619 depending on model. This is the most common fix for a black screen. For your specific model's pricing, use the repair calculator or see all 75+ models with pricing.
Board repair: $149–$399 for display IC replacement. Only needed if a screen replacement doesn't fix the issue — a good shop will diagnose this before charging you for a screen.
Tip: Always ask the shop to test with a known-good screen before replacing yours. This takes 5 minutes and confirms whether the problem is the screen or the board. A reputable shop will do this as part of their diagnostic process.
