Start with the simplest fixes first

A tablet screen that does not work usually means one of three things: the display is off but the tablet is running, the screen is frozen and will not respond to touch, or the glass is cracked or physically damaged. Before you assume the hardware is broken, try these steps in order, because most screen problems come from software glitches or straightforward settings you can reverse in under five minutes.

First, hold the power button for 10 seconds until the tablet shuts down completely. Wait 30 seconds, then press the power button again to turn it back on. This forces a full restart and clears temporary software errors that freeze the screen. If the tablet vibrates or shows a logo when you press the power button, the device itself is working—the problem is isolated to the display or touch layer.

If the screen stays black after restart, try plugging the tablet into a charger for at least 15 minutes. A completely drained battery can make the screen appear dead even though the tablet is trying to power on. You may see a charging indicator (a light, a logo, or a vibration) that tells you power is reaching the device.

Key Takeaways

  • Restart the tablet by holding the power button for 10 seconds, waiting 30 seconds, then powering it back on—this fixes most frozen or unresponsive screens.
  • Charge the tablet for at least 15 minutes because a dead battery can make the screen appear broken when the device is actually trying to start.
  • If the screen is black but the tablet vibrates or shows a charging light, the hardware is working and the problem is likely software, not physical damage.
  • Check whether the screen is actually off or just very dim by adjusting brightness in settings or covering the light sensor to see if auto-brightness is the issue.
  • Physical cracks, water damage, or a screen that does not respond to any touch usually means the display hardware needs replacement and cannot be fixed by software steps.

Check brightness and display settings

Sometimes the screen is on but so dim you cannot see anything. On most tablets, swipe down from the top of the screen to open the quick settings menu, then look for a brightness slider. Drag it all the way to the right to maximum brightness. If you cannot see the menu because the screen is too dark, try swiping anyway—the tablet is responding even if you cannot see it.

Many tablets have auto-brightness turned on, which dims the screen in low light. If your tablet is in a dark room or you are holding your hand over the light sensor at the top of the device, the screen will dim to almost nothing. Move to a brighter area and make sure nothing is covering the top edge of the tablet.

If the screen is still black after you have turned brightness to maximum, check whether the tablet is in a power-saving mode that turns off the display. Go to Settings, then look for Battery, Power, or Display options. Turn off any power-saving or low-power mode, then restart the tablet again.

Force the tablet to respond if the screen is frozen

A frozen screen that shows an image but does not respond to taps usually means an app has crashed and locked up the system. The fastest way to unfreeze it is to force a restart: hold the power button and the volume-down button at the same time for 10 to 15 seconds. The tablet will vibrate and the screen may go black—this is normal. Release both buttons and wait for the tablet to restart.

If that does not work, try holding only the power button for 30 seconds without releasing. Some tablets require a longer press to trigger a force restart. You should feel the tablet vibrate two or three times before the screen goes dark.

Once the tablet restarts, it will load normally. If the same app froze the screen before, do not open it again when ready. Instead, go to Settings, find Apps or process Manager, locate the app that crashed, and select Uninstall or Clear Cache. Clearing the cache removes temporary files the app stored, which often fixes crashes without losing your data.

Disconnect and reconnect the display cable if you are comfortable opening the tablet

If the screen is completely black, the tablet vibrates when you press the power button, and you have confirmed the device is charged, the display cable may have come loose inside. This is a hardware fix that requires opening the tablet, so only attempt this if you are comfortable working with small electronics and have a plastic opening tool or old credit card to pry the case apart gently.

Power off the tablet completely and unplug it from the charger. Look for a seam around the edge of the tablet—usually along the bottom or side—and slide a plastic tool into the gap to separate the back cover from the frame. Work slowly around the edges to avoid cracking the plastic. Once the back is open, look for a flat ribbon cable connected to the screen. Gently pull the connector straight out, wait 10 seconds, and push it back in until you hear or feel a click.

Close the back cover, power on the tablet, and check whether the screen now displays an image. If it does not, the cable may be damaged or the display itself may be faulty, which means you will need to replace the screen or take the tablet to a repair shop.

Identify physical damage that cannot be repaired at home

If the screen has visible cracks, the glass is shattered, or the tablet was recently dropped in water, the display hardware is damaged and software fixes will not help. A cracked screen may still show an image or respond to some touches, but it will not work reliably and the damage will spread over time.

Water damage is harder to spot. If the tablet was wet and the screen stopped working shortly after, liquid may have corroded the connections inside. Do not try to charge or restart a water-damaged tablet repeatedly—this can cause short circuits. Instead, let it dry completely in a warm, dry place for at least 48 hours before attempting to power it on again. If it still does not work after drying, the internal damage is likely permanent.

Tablets with physical damage or water damage need professional repair or replacement. Contact the tablet manufacturer's support line or visit an authorized repair center to get a quote. Some damage is covered under warranty, depending on the brand and how old the tablet is.

Test the screen with safe mode to rule out app problems

If the screen is working but behaving strangely—flickering, showing strange colors, or responding slowly—a recently installed app may be causing the problem. Boot the tablet into Safe Mode, which disables all third-party apps and runs only the system software. This tells you whether the issue is the hardware or an app you installed.

To enter Safe Mode, hold the power button until the power-off menu appears, then press and hold the "Power off" option until a Safe Mode prompt appears. Tap OK to confirm. The tablet will restart and you will see "Safe Mode" in the bottom left corner of the screen.

Use the tablet normally in Safe Mode for a few minutes. If the screen works perfectly and shows no flickering or problems, the issue is an app. Restart the tablet normally, then uninstall the most recently installed apps one at a time until the problem stops. If the screen still has problems in Safe Mode, the display hardware itself is faulty.

Update the operating system if the screen is slow or unresponsive

An outdated operating system can cause the screen to lag, freeze, or respond slowly to touches. Check for system updates by going to Settings, then About Tablet or System. Look for an option that says Software Update, System Update, or Check for Updates. If an update is available, plug the tablet into a charger and connect to Wi-Fi, then read and install it. The tablet will restart during the process, which is normal.

System updates often fix bugs that affect the display and touch response. After the update finishes and the tablet restarts, test the screen again to see whether it is more responsive. If the problem persists after updating, the issue is likely hardware-related and the steps above will not resolve it.

Know when to stop troubleshooting and seek repair

If you have restarted the tablet, charged it fully, checked brightness settings, forced the screen to respond, and tested in Safe Mode, and the screen still does not work, the problem is almost certainly a hardware failure. At this point, further troubleshooting will not help and may damage the device further.

Contact the tablet manufacturer's support team or visit an authorized repair center. Have ready the tablet model number (found in Settings under About), a description of what the screen does or does not do, and information about any physical damage or water exposure. A technician can diagnose the exact problem and tell you whether repair or replacement is the best option.

Frequently Asked Questions

What should I do if the screen is cracked but still shows an image?

A cracked screen can still display and respond to touch for a while, but the damage will worsen over time and may eventually cause the display to fail completely. If the crack is small and does not affect your use, you can continue using the tablet, but plan to replace the screen soon. If the crack is large or spreading, stop using the tablet to prevent further damage and contact a repair shop.

Can I fix a screen that got wet?

Do not try to restart a wet tablet when ready. Power it off, remove the charger, and let it dry in a warm, dry place for 48 hours or longer. After it dries completely, try powering it on. If water reached the display connections, the screen may not work even after drying, which means the hardware is damaged and needs professional repair.

Why does my screen flicker or show strange colors?

Flickering or color problems usually come from a recently installed app, outdated software, or a loose display cable. Try Safe Mode first to rule out apps, then update the operating system. If the problem continues, the display cable inside may be loose or the screen hardware may be failing, and you will need professional repair.

How long does a tablet screen usually last?

Tablet screens typically last several years with normal use. Damage from drops, water, or pressure on the glass is the most common reason screens fail. If your tablet is older than five years and the screen stops working, replacement may cost more than the tablet is worth, so consider whether upgrading is a better choice.

Will restarting my tablet erase my data?

A normal restart does not erase any data—it just turns the tablet off and back on. A factory reset erases everything, but that is a different action you have to choose deliberately in Settings. If you are only restarting to fix the screen, your photos, apps, and files will remain untouched.
