lcd touch screen dead spot in stock

Dead zones on phone and tablet screens are one of the rarest and irritating issues you can come across on your device. If you’re unable to use your device as usual because of its unresponsive touch screens, there are a handful of fixes you can try at home to resolve the problem. This article sheds light on various solutions on how to fix dead zones on phone & tablet screens.

Whether it’s the middle of the touch screen not working, the right side of the touch screen not working, or anywhere not working on the screen, this article will help you fix it. You might not need to visit a repair center too.

Before looking for how to fix dead zones on a phone screen, there are a few things to note. What causes unresponsive touch screens most times is because the screen is cracked. Broken screens may cause some parts of your display to malfunction, especially when exposed to moisture, water drops, and others. If that’s the case, we recommend you go for a screen replacement instead.

More so, if you have a screen protector on your phone, simply take it off. Sometimes, probably because of poor fixing, your screen protector may cause dead pixels on a phone. If you"re wearing a glove or anything is covering your fingers, kindly remove them.

As simple as it is, restarting your phone can fix the dead zones on screens, as well as other issues. And that’s a quick way to diagnose if it’s a hardware problem or some software glitches hanging around the corner.

The next thing to do when experiencing ghost touch or unresponsive touch on your device is to test the part of the screen that is affected. This is surely a way to get to the root of the problem.

While some people experience the middle of the touch screen not working, some might be the right side of the touch screen not working. In that case, you need to check what part of your screen is not functioning.

To do that, we’ve chosen a simple app called Touchscreen Test.You can install it from the Play Store or get its equivalent for your iPhone on the App Store, then follow the steps below.

Ghost touch, dead pixels, and unresponsive touch screens are not always hardware problems on mobile devices. Sometimes, it may be because of an app you installed earlier - a poorly coded or malware-ridden app.

To ensure that what caused unresponsive touch screen on your device is not an app, you need to boot into Safe Mode. In this mode, your phone only loads the system apps. Other apps are paused/disabled until you exit Safe Mode.

Similarly, if you’ve turned on Developer Settings on your phone, you may need to turn it off to fix the dead pixels on the screen – at least on a software level.

Another method of fixing an unresponsive touch screen on your phone is to power it off and remove all the peripherals connected to it – your SIM cards, micro SD card, earphones, and others.

Though rare, your SIM and SD card may go haywire and tamper with some functions on your phone. And most times, the issues seem to disappear after pulling out the SIM card and SD card. So you can try it to fix dead pixels on your screen.

If you experience ghost touch (the screen pressing itself), or an unresponsive touch screen only while charging your phone, the culprit might be that charger you’re using.

The first thing to do in that case is to remove the charger. If the screen behaves normally after removing it, then you might need to get a new charger, or better still, change the cable. Also, if the charger amperage is more powerful than what your phone can occupy, it can affect the screen.

If none of the methods above could fix the dead pixels on your phone screen, you might want to try a more technical solution at home. This method requires you to use an igniter – usually found inside an electronic lighter at home – to create static electricity and fix the dead pixels on your screen.

Warning:though this method has a high chance of fixing dead spots on touch screens, it will void your warranty, and it can damage your display irreversibly. Also, it’s just a temporary fix most times - dead zones may reappear after a few hours, days, or months. So, try at your own risk. Meanwhile, you"re better off visiting a repair center.

As we said earlier, this method will void your warranty and may incurably damage your screen. So, try it at your own risk. And if it worked for you, you may need to keep the igniter at reach in case your dead spots reappear. This method will also fix ghost touch on your screen if you have it.

The last resort if none of the above fixes work, or if you don"t want to lose your warranty to an igniter, is to look for how to repair the touch screen of a mobile phone.

You need to visit a repair center to fix the dead zones on your screen. We recommend you visit the official repair center if your brand has one. They will help you diagnose and fix the problem in a short time. Also, if you need to replace your screen, they will help you out.

Meanwhile, if you’re TECNO, Infinix, or itel device is still under warranty and you don’t have a broken screen, we’ll fix the dead zones on your screen for free!

Though it"s impossible to gauge how widespread the problem is, a number of users are reporting an issue where certain spots on the iPhone"s MultiTouch screen -- particularly a strip about 1/2 inch in height somewhere below the top of the screen -- will not accept input. If indeed you have a defective screen, Apple is apparently willing to replace it with little hassle. However, to ensure that a more innocuous issue isn"t at play, try the following first:

Reset your iPhone Sometimes, ostensibly dead spots on the screen are merely the result of frozen applications or an unresponsive interface rather than actual hardware failure. Press and hold the Sleep/Wake button (on the top of the unit) and the Home button simultaneously for several seconds until the Apple logo appears and check for persistence of the issue.

Clean the screen It may sound trite, but a glaze of any foreign substance can cause operational difficulties for the iPhone"s screen. Clean the screen with the cleaning cloth that came in the box with the iPhone.

Restore your iPhone As a last resort, try restoring. This can remove lingering software issues that might be causing a lack of screen response. To perform a restore, Connect your iPhone to your Mac or PC and, in iTunes, click the Restore button under the Summary tab. Restoring the phone will erase contacts, calendars, photos and other data on the phone, but will restore automatically backed-up information including text messages, notes, call history, contact favorites, sound settings, widget settings, etc.

Also, if you are indeed experiencing a hardware failure, please drop us a line indicating what version of screen your iPhone uses. To discover this information, put your iPhone in field test mode by accessing the Phone application, tapping Keypad, then entering *3001#12345#* and pressing Call. Tap Versions, then inspect the entry next to LCD Panel ID. Let us know whether your iPhone is a 7 series or 5 series

A few days ago the lower part of my device"s touchscreen went dead. Whenever I touched the bottom 2 to 3 centimetres of my screen, it simply wouldn"t respond, meaning that the spacebar and a few of the letters on the keyboard didn"t work, along with the buttons in some apps. So I did some research on Google, tried a few solutions ranging from performing a soft reset to taking the phone apart and making sure all the parts were connected correctly, but no luck. A few hours later, my phone ran out of battery and when I restarted it the problem had gone, only to return about 15 minutes later. Therefore, I"m pretty convinced that the problem is software rather than hardware based and am reluctant to perform a hard reset or to replace the digitiser. What should I do instead?

I think I figured it out It may help try it. The ghost touches could be from a lose screen that has to be fix are software. But you would have to determine that by these steps. I figured the screen would either be messed up if you dropped it and the cable is lose are a defect and can cause ghost touches are screen scrolling are wacky things going on with your screen physically or could be static shock if you do not have a static free cover or your power adapter if it"s not original for the phone are a different kind can cause it as well all this I found out just doing everything I could think of that may cause this thing to act up. Unless you have a static free case or antishock case that may cause the problem as well. As I went a whole day without plugging in my charger after I done a few things that I will explain threw this whole thread that it did not act up one time with out plugging in my charger I used a charger for my samsung galaxy as it the same volts nothing different. There is a dead spot on the screen where no matter what you do it will not let you touch anything and it"s toward the top in a straight line across. Very seldom it will let you touch anything and I think it"s where the ghost touches are right in that spot.Now for software. No matter if you reset your phone from the hard reset if your signed up with google unless you go vanilla and not let google download everything you had on there again your in trouble if you do. For one it"s software problem that has not been fixed and for 2 when cutting on and off it stops sometimes that"s software. Now for the good part what others may find out is if you go in and reset your phone with just says reset to default instead of starting from scratch the phone doesn"t act up. This phone is very picky on what it wants on it. Also I found that it could be the facebook app causing it to do this!! I promise you once I reset my phone to default and deleted the facebook app I had no problems yet all day!! Because as I got notifications from facebook on my phone locked up and started the wacky and not responding and all other kinds of things with ghost touches and all. I looked at facebook from the web with google chrome after the app was off again and no problems. Also I found out that if you do not use the default text keyboard are the default text message program on the phone no matter if you like what it does are not it will cause you problems!! I will update and let you know as I go threw finding out what really happens with doing all this again!! Thanks and hope this helps a lot of people as it certainly had me stumped. I love this phone but couldn"t use it will get back as I find more problems if things start to acting stupid again. OO and I have the verizon VS980

For example, on a device that is stable at a single touch, it is also easy to check the phenomenon becomes unstable when it comes to three or more points.

You probably touch your phone"s screen hundreds of times per day. Combined with its delicate glass build, it"s no surprise that smartphone touchscreens are one of the most common components to run into issues.

But the touch screen not working on your Android phone isn"t always the result of a hardware failure. If your phone touchscreen often isn"t working or fails to respond, there"s a lot you can do before getting professional help.

First, you should rule out the possibility of a software bug if your phone touch screen is not working. There are a handful of troubleshooting steps you can do to confirm this.

A good-old reboot might sound futile to fix such an advanced issue. However, it"s often one of the most successful ways to fix an unresponsive touch screen on Android. Restarting your phone shuts down and refreshes all background services, which could have crashed and led to your issue.

If you"re unable to touch the screen to select the option, on most devices, you can hold down the Power button for several seconds to switch off your phone. In some cases, you may need to hold down the Power button and the Volume Up button at the same time.

If your touch screen is not working, but only intermittently, then you may be able to re-boot your phone into safe mode. Android"s safe mode lets you use your phone with only the original software it shipped with, which strips out all services and apps you"ve installed. If your display works normally in safe mode, a third-party app is likely at fault here.

To enter safe mode on most new Android devices, press and hold the power button. In the resulting prompt, touch and hold the Power off button. Once you see the prompt to enter safe mode, tap OK, and your phone will soon restart. To exit safe mode, just restart your phone normally.

If you"re scratching your head wondering, "Why is my phone touchscreen not working?", you"ll find a range of apps on the Play Store that could help you to diagnose your display issues. These are designed to pinpoint what exactly is wrong with your phone"s touchscreen. We recommend trying out one simply called Display Tester.

When you launch Display Tester, head into its Tests tab. Here, you have the option to test a whole bunch of aspects. The app can detect dead pixels, burn-in on OLED screens, whether the contrast and saturation are accurate, multi-touch status, and more.

If you got positive results in touch-based tests, you should review all recently installed apps or consider performing a factory reset. Since your touchscreen functioned as intended under special circumstances, a third-party app is most likely the root cause.

Many people apply a screen protector on their phones as an added safety against drops and scratches. But that same sheet of plastic or glass could prevent your touch signals from reaching the display panel.

If your phone"s screen has been acting up lately, try removing the protector. Of course, this doesn"t guarantee a fix. However, it could increase the response rate on an already weak screen.

Touchscreen Repair is a lightweight app that calibrates your screen to reduce response times. The app asks you to consecutively tap several sections of the touchscreen. Based on your phone"s internals, it then artificially drops the latency as much as possible.

The effectiveness of Touchscreen Repair varies depending on your phone maker. Many OEMs ship their phones with optimal response rates. In those scenarios, Touchscreen Repair won"t be able to do much. But it"s worth a try if nothing else has worked yet.

You don"t have to rely on touch inputs to control your phone. To better serve users with accessibility needs, voice and facial-based interaction methods for Android have come a long way.

With the right apps, you can navigate on your phone entirely through your voice and facial movements. Of course, these solutions only apply if your phone"s touchscreen works enough to install an app from the Play Store.

Else, you can try installing the app to your phone through the Play Store web interface. And you can disable touchscreen input on your phone until you get the screen fixed.

Google"s Voice Access app proactively listens for your commands and assigns a number to every action available on the screen. Instead of touching an app icon or menu element, you just have to call out the assigned digit.

Voice Access links fundamental actions to fixed phrases. So you can say "screen down" for moving around pages and "go back" to return to the previous screen, for example.

This app does exactly what its name suggests. It adds a virtual cursor on your screen, which you can manipulate with your face. To move the pointer, you simply have to move your head in the appropriate direction.

If you can"t install any apps due to screen problems, connecting an external keyboard and mouse might do the trick. This assumes you can still see the screen, though.

With these possible fixes, you should hopefully be able to revive your phone"s touchscreen if it"s just a software bug. Failing that, the apps mentioned can grant you a temporary workaround.

Otherwise, you will have to visit a service center for help. If you"re lucky, a professional will be able to restore the touchscreen"s functions, although depending on the device, it may be a pricey repair. If not, you"ll have to look at replacing your phone.

Your Android touch screen might not be working for various reasons. Hopefully, one of the fixes above helped solve your touch screen issues. If everything fails, perhaps it"s time to upgrade.

Your iPhone"s touchscreen is its defining feature. In fact, an iPhone is essentially useless without a working touchscreen, so if it fails to respond to your touch, it"s a problem you need to solve — immediately.

The good news, though, is that unless there"s a fatal hardware problem that requires a trip to an Apple store to get the entire phone repaired or replaced, you may be able to get it up and running again with a few simple fixes.Quick tip: If your iPad touch screen isn"t working either, there are several other ways to troubleshoot the issue.

If your iPhone"s touchscreen is not working, try each of these troubleshooting tips. Hopefully, one of these will get you up and running. If not, it"s likely you have a hardware problem that may only be fixable by contacting Apple customer service to repair or replace your phone.

If your iPhone has gone completely haywire, the first thing you should do is restart it — turn it off completely, wait a minute or two, and then turn it on again. Restarting an iPhone can wipe out temporary glitches in memory, which can restore, for example, an unresponsive screen.

Of course, if the touchscreen is not working, you can"t shut down the phone in the usual way using the Settings menu; you"ll need to force the phone to restart by pressing some combination of power and volume buttons.

The iPhone uses a capacitive touchscreen that senses your fingertips using electrical conductance. That means various things can interfere with the way your screen works — dirt and grime can affect it, but a much larger problem is moisture and liquid. If the screen is wet or even just damp, dry it thoroughly and try again.

The Whoosh! Cleaning kit is an inexpensive solution to keeping your iPhone screen clean and working properly. We chose it as one of the best iPhone accessories you can buy.Whoosh! Screen Cleaning Kit, $9.99 from Amazon and Target

On rare occasions, an accessory plugged into the phone"s Lightning port could interfere with the touchscreen. If anything is plugged into the port — including a power bank or charger — unplug it. If that solves your problem, the accessory or cable might be incompatible with the iPhone.

The iPhone"s touchscreen may seem robust enough to work virtually flawless all the time, but it only works properly in a surprisingly narrow set of conditions. For example, the touchscreen can stop working if you apply a screen protector that"s too thick, making it impossible for the screen to sense the electrical capacitance in your fingers.

If the touchscreen isn"t working — or is working intermittently — remove anything on or around the screen, including the phone case and any screen protector that"s keeping the screen from getting scratched. If it works after removing those accessories, get a different case and/or look for a thinner screen protector.

If your iPhone has recently stopped responding to your touch and nothing else so far has worked, it"s possible there"s a serious hardware issue and the phone needs to be repaired or replaced.

4. On a Mac, you should see the option to restore or update your iPhone. Click Restore and follow the directions to perform a factory reset. On a PC, click the Device button in the top left of iTunes. Then select Summary, then Restore, and follow the onscreen instructions.

If you still have no luck getting the touchscreen to respond, it"s almost certain that you have a hardware problem with your iPhone and it needs professional help. Contact Apple"s customer support to see if it is eligible for repair or replacement.Dave Johnson

Slowly drag your finger to the bottom right corner without lifting. Try to move your finger slowly enough that you can count to 10 before reaching the opposite corner of the screen.

Under your Pixel 5 phone’s screen, at the top center, you can see a white dot. This white dot is your proximity sensor. When your proximity sensor is on, the dot shows through the display. The dot can blink or stay solid.

Your proximity sensor keeps your phone’s screen off while you hold your phone near your face during a call, when your screen is locked, and when used by certain apps. Keeping the screen off helps save battery and avoid accidental taps on the screen.

All Pixel phones have proximity sensors. Because the Pixel 5’s display goes almost to the edge, you can see the Pixel 5’s sensor under the screen. Check our Pixel 5 phone diagram.

Touch screens are great when they work, but when a touch screen stops working, all that ease of use goes out the window and frustration sets in very quickly. The biggest problem is that with some devices, the touch screen is the only way you have of interacting with your phone or tablet. When that suddenly goes away, it can feel like you’re totally locked out of your device altogether.

While there are cases where an unresponsive touch screen calls for professional repairs, there are a number of steps, from easy to advanced, that you can take to get things working again.

Restart the device. It may sound pretty basic, but when your touch screen stops working, simply restarting your touch screen device is usually all it takes to fix the problem.

Clean the touch screen and screen protector. In some cases, a touch screen will stop responding properly due to built up dirt and grime or problems with the case or screen protector. Since this is pretty easy to either deal with or rule out, it’s a good idea to give your device a thorough cleaning if a reboot didn’t do the trick.

Clean your hands to avoid passing dirt onto the screen. Wipe the touch screen with a lint-free cloth. The cloth may be dry or wet, but never use a sopping wet one.

Another slightly more complicated fix for a touch screen is to simply turn the device off and remove all of the sim cards, memory cards and peripherals. The reason this can be complex is that these cards are sometimes difficult to remove, and you have to put them back in one at a time to figure out which one was the problem.

Dry off your smartphone. Touch screens can also stop working, become unresponsive, or work erratically if a phone gets wet. In that case, drying the phone out thoroughly sometimes fixes the problem. There are several steps to drying out an Android and drying out an iOS device.

Gently tap each corner of the phone.When a touch screen stops working after a phone is dropped it’s sometimes due to the digitizer connection coming loose internally. In that case, gently tapping on each corner of the phone may cause it to reconnect.

Remove the SIM card, memory cards, and peripherals.While it is less common, problems with SIM cards, memory cards, and peripherals (such as USB devices) can sometimes cause touch screen problems in mobile and Windows devices. Be sure to fully power down and unplug your device first.

Since touch screen problems can also be caused by files or programs that you download, the next step is to start up your phone, tablet or laptop in safe mode. This is basically just a bare bones mode that doesn"t load extra programs, but it can be pretty complicated to get it going.

Turn on Safe Mode for Android or Windows safe mode. In some cases, a problem with an app or program that you have downloaded can cause the touch screen to become unresponsive. The key to figuring this out is to restart in safe mode, since these apps and programs don’t load in safe mode.

If you find that the touch screen starts working when you enter safe mode, then there is a problem with some app or program that you downloaded. Start with recently downloaded apps and go from there.

Adjust iPhone 3D Touch sensitivity. If you’re experiencing an unresponsive or inaccurate touch screen on your iPhone 6s or later, it may be a 3D Touch sensitivity issue. In that case, assuming the touch screen works at all, you’ll need to adjust that setting.

Go to Settings > Accessibility > Touch > 3D & Haptic Touch.Adjust the slider between light and firm. Try turning off 3D Touch if the screen is still inaccurate or unresponsive.

Calibrate your Windows touch screen. The Windows Touch Screen Calibration Tool helps to reset the center of each touch you make on your device. If you find that your touches seem to be a little off, this might help put everything right again.

If you have a Windows device with a malfunctioning touch screen, then updating the driver might fix the problem. Disabling and re-enabling the driver or reinstalling it might also do the trick.

If your touch screen still doesn’t work after following all of these steps, then it will probably require professional repairs. If those don"t work, it"s time for a new phone.

Does your Samsung phone have a frozen touchscreen? Has your iPhone X touchscreen stopped working? Touchscreens are fantastic, except when suddenly they’re not: unresponsive touchscreens are more common than you might think. To say that an unresponsive touchscreen or a touchscreen that is not responding properly is a very frustrating experience would be an understatement!

Android and iPhone users encounter this issue every day. While this inconvenience could indicate that it’s time for a new device, there are also a few simple fixes you can try when an iPhone touchscreen is glitching or when a Samsung display touch is not working. If your cell phone or tablet screen is taking on a life of its own, you’ll need to find the root cause and decide on a suitable solution.

A smartphone touchscreen can become unresponsive for several reasons. For example, a brief hiccup in your phone’s system could render it unresponsive; a screen may also become unresponsive after incurring water damage. Other factors may include debris, app glitches and viruses.

In the absence of these issues, there’s a possibility the screen could be damaged because of an accident. This situation may call for repairs or replacements. That said, you can save time and energy by trying a few quick do-it-yourself fixes first.

Users of iPhones or iPads may find that their screens suddenly freeze. Perhaps your iPad won’t recognize touch and does not rotate when you turn the device. Maybe your iPhone 6 screen is moving by itself, or your iPhone screen stops working sometimes. It’s often confusing to know what to do when your iPhone touchscreen is not working. You tap it or swipe it, and it does nothing in return. Ugh!

Don’t throw in the towel just yet. Determining how to fix touchscreens that aren’t working on iPhone or iPads may be as easy as performing some simple tweaks. The easiest solution to stop your phone screen from glitching (as well as to stop an iPhone screen that’s moving without touching or to remedy an iPad touchscreen not working intermittently) is to shut the phone off and restart it.

There are other considerations and tips to perform when an iPad or an iPhone won’t respond to your touch. Based on your iPhone’s model, a lack of responsiveness may come down to:

Touch Disease: Users of the iPhone 6 and 6 Plus noticed a flickering section toward the top of the screen and subsequently found the device wouldn’t respond.

However, the issue could also be software based. The phone touchscreen may no longer respond when the device needs a firmware update or when too many apps consume its memory.

A non-working touchscreen can be an urgent issue if you rely on your device every day; an Android phone or tablet not responding or an Android touchscreen that’s not working can really cause issues. An iPhone screen that does not respond to touch (or doesn’t respond at all) can be worrisome, especially since it seems like our lives are all on these devices.

These tips will teach you how to fix an unresponsive iPhone screen or Android screen without having to pay for repairs. Try out these methods on your phone first:

Reboot the phone: You can fix an iPhone with an unresponsive touchscreen by rebooting the device. If you’re unable to shut down the phone normally, press “Volume Up,” “Volume Down,” and then hold the side button until the logo appears. You can restart and Android phone without a touchscreen by holding the power button for 30 seconds.

Make sure your device and hands are clean: Moisture, debris and oils on your hands or device can impact its screen performance. We recommend washing and drying your hands and then wiping down the device with a soft cloth before trying the device again.

Check the screen protector: Even if the screen itself is clean, the protector on top may be the issue. Ensure that it’s correctly applied to the surface or consider taking off the case to reapply it. Once you take off the protector, you can test the touchscreen to see how well it responds. Should it become responsive at this point, you may want to consider a thinner protector.

Update your device: Older versions of software often come with bugs that updates are designed to fix. Ensuring that your Android or iPhone device is up to date may improve screen performance issues, particularly if it is unresponsive to touch. You can find available software updates by visiting your device’s “Settings” app.

Use Safe Mode: If you’re looking for a way to fix your Android screen that’s unresponsive, try running it in Safe Mode. This feature disables third-party apps to help you troubleshoot issues. The latest iPhone also offers a Safe Mode feature so you can identify apps that may be untrustworthy.

Do a hard factory reset: In extreme cases, you can fix an unresponsive iPhone or Android screen by returning the phone to the phone or tablet’s factory settings. This will wipe all your data and personal content from the device, though, so make sure you have everything backed up first if possible.

If all the above methods prove ineffective and you’re still experiencing iPhone lost touchscreen sensitivity or a touchscreen that’s not working on your Samsung device, you might have a bigger hardware issue to address. In this case, you can either pay for a repair or sell your broken phone to buy a newer model. At The Whiz Cells, we offer great cash values for your old devices. While broken phones are worth less than fully functional ones, we’ll be glad to accept your device to put some extra cash in your pocket to pay for that much-needed upgrade.

We must verify whether the problem is the display screen of the laptop, video card (GPU), or video settings on the computer. A straightforward way to identify this is to connect the laptop to an external monitor or TV.

If the issue persists on the external monitor, it may be an issue with the video card (GPU) or video settings and not the laptop LCD panel. Go to verify display or video issues in Windows Safe Mode. Otherwise, go to the next step.

Performance issues may occur if there is any damage to the LCD screen. The display may stop working, work intermittently, flicker, display horizontal or vertical lines, and so on, if there is damage to the display screen.

Dell laptops have integrated diagnostic tools that can determine if the screen abnormality is an inherent problem with the LCD screen of the Dell laptop or with the video card (GPU) and computer settings.

When you notice screen abnormalities like flickering, distortion, clarity issues, fuzzy or blurry images, horizontal or vertical lines, color fade, running a diagnostic test on the LCD helps identify if the issue is with the LCD panel.

Press and hold the D key and turn on the computer to enter the LCD built-in self-test (BIST) mode. Continue to hold the D key until you see the entire screen change colors.

If you do not detect any screen abnormalities in the integrated self-test mode, the LCD panel of the laptop is functioning properly. Go to the Update the video card (GPU) driver, monitor driver, and BIOS section.

If you notice any abnormalities in the LCD built-in self-test mode, contact Dell Technical Support to learn more about repair options that are available in your region.

Display settings like brightness, refresh rate, resolution, and power management may affect the performance of the LCD screen on your Dell laptop. Changing or adjusting the display settings can help resolve several types of video issues.

If you find that the Dell laptop is unresponsive to touch, touch stops working entirely, or other touch-related issues, you can try some common troubleshooting steps to help fix the touch-related issue.

If the diagnostic tests on the LCD panel and the video card (GPU) passed, it is most definitely an issue that is related to software that is installed on the computer. If the above troubleshooting steps did not resolve the issue, you may try to restore the computer to factory default settings as a last resort.
