How to show images on screen


Step 1 Turn the device off, wait a few seconds, and then turn it back on again. This process will clear out any software errors that are causing the touchscreen to malfunction. If the touchscreen still doesn't work, remove the device's battery, if possible, wait ten seconds and then put it back in.
Step 2 Remove both the SIM and memory cards from the device, if the device accepts such cards, and then turn the device off and back on again. Sometimes errors in these cards can cause devices to malfunction.
Step 3 Check your device's documentation to see if there is a way to manually recalibrate the screen. This process will either be done through the "Settings" or "Tools" menus, for those devices that have an alternative method of input, or by holding a combination of buttons while you turn the device on, for those devices that only have the touchscreen for input.
Step 4 Upgrade the device's software to the latest version, if possible. Many devices come with software for your computer that will allow you to connect the device and update the software. Often, this process will resolve existing software errors that may be causing the touchscreen to stop responding.
Step 5 Clean the device's contacts and screen using isopropyl alcohol and a small brush. Turn the device off before you clean it.
Step 6 Perform a hard reset as a last resort. This reset will erase everything you have added to the device and return its software and settings to their factory defaults. Even with an unresponsive touchscreen, most devices will have a way to perform this reset either through PC software or by holding a combination of buttons while turning the device on. Consult your device documentation to determine the exact process for performing a hard reset on your device.
Step 7 Contact the manufacturer for your device if the touchscreen is still unresponsive after your troubleshooting attempts. The manufacturer may have additional steps to take that are specific to your device, and if your device is still under warranty you should be able to get a replacement through their customer service division.
Warnings
  • If you have the right tools and are willing to risk voiding your warranty, you can also open the device and scrub down the control board using the small brush and isopropyl alcohol.
  • Many manufacturers offer free telephone support, but some will charge for the service. Check your product documentation before you contact support to know if you will be charged for the service.

Required Items

  • Isopropyl alcohol
  • Small brush

I am having touchscreen access to icons on my huawei , The touchscreen will not let me open the lowere icons i.e.home, apps etc, any advice is most welcomed!Thanks J


hi,
unfortunately the symptoms you describe show that the digitizer(touchscreen) of your phone is bad and theres no way to fix it domestically. in newer phones, the digitizer is glued to the screen of the phone to enhance its response when you touch it , so when it malfunctions like in your case you are left with only one choice to have the entire screen replaced. the upside though is that these parts are readily available from your local fix it shop.
hope this sheds some light.
goodluck mate

TOUCH SCREEN NOT WORKING

DO NOT OPERATE AS TOUCH PANTLLA
Touchscreen computers and handheld devices are the newest wave of technological gadgets as of 2010. While these devices function impressively, they can malfunction just like any other technical device. Troubleshooting the touchscreen is simple and often will correct any issues.

Identify how the screen is behaving. A touchscreen will malfunction in one of two areas--sensitivity or position. If you touch the screen and the cursor is not centered on your finger, this is a position error and requires recalibration of the screen. If you touch the screen and it does not register your touch without pressing hard, this is a sensitivity error. If you touch the screen and nothing happens, this can be a sensitivity error or a malfunctioning screen. Calibrate the screen. For all main errors, calibrating the screen will correct the issue. Every device has a different method of calibration but can usually be found under a "Tools" or "Diagnostics" menu option. Reload the device. For handheld devices, remove the battery and let the device rest for no less than five minutes. For computer or computer system devices, power down the device, disconnect the touchscreen device from the computer and remove any power cords to it. Allow the device to rest for five minutes. Reattach the device or reinstall the battery and power up the device. If issues persist, reload the software for the device. For handheld devices, do a full wipe of the device and return it to factory specifications. For add-on devices to a computer or computer system, uninstall the device and reinstall the drivers. If reloading, registering or calibrating the device does not work, consult the manufacturer for possible warranty replacement options.

My v touch pro touch screen wont work


b> The Touch Pro2, manufactured by HTC, is a smartphone designed to be used with the Verizon wireless phone network. This smartphone combines a cell phone, PDA, MP3 player and wireless Internet access into a small, portable device. If the device begins malfunctioning or freezing, you can perform a soft reset. A soft reset does not delete any of your saved information. It shuts the phone down and reboots the phone to the Verizon Today Welcome Screen.

Pull the stylus upward to remove it from the side of the phone. Push the back cover upward using your thumbs until it pops from the back of the Touch Pro2 phone. The back cover can then be lifted away and removed from the phone. Press the "Reset" button, on the upper, left side of the back panel using the stylus tip. The device will now restart and display the Verizon Today screen. Snap the back cover back onto the back of the phone. Touch Screen is Not Working
As most tablet PCs ,Phones and Mp3 players are full touchscreen devices, you use your touchscreen for everything you need to do on your Tablet PC. If the touchscreen stops working, you can't get much use out of your Tablet. Touchscreen issues are caused by hardware or software problems, but check with your manufacturer before attempting a DIY repair.

Hardware Issues Damages to the surface of your Tablet PC can cause the touchscreen to malfunction or stop working entirely. For example, putting pressure on the screen, such as placing the Tablet PC in a bag with other heavy items, can cause cracking along the screen. Exposing the screen to water, even in small amounts, can cause the electrical system within the touchscreen to malfunction. If the electrical system malfunctions, the touchscreen stops working properly. b> Screen Sensitivity b> Pressing the touchscreen on your Tablet PC sends a signal to the internal motherboard. The motherboard then transmits to other components, such as the hard drive. The accuracy of the touchscreen depends on the screen's sensitivity. Many Tablet PCs include a program for calibrating the touchscreen. This program may fix minor responsive issues. Even a small amount of dirt or debris can effect how the touchscreen responds. Cleaning your touchscreen with an electronics cleaner or a microfiber cloth may help improve sensitivity. b> Software Issues b> A driver is a software program that interacts between hardware devices and an operating system, Your Tablet PC needs the right drivers for your OS to work correctly. Outdated or missing drivers can cause the touchscreen to work improperly, or not respond at all. Visit the manufacturer's website to find the right drivers for your Tablet PC. b> Repair b> While you can perform some minor repairs yourself, such as re-calibrating the touchscreen sensitivity or installing drivers, only perform a hardware repair if you have a good working knowledge of electronics, specifically Tablet PCs. Before attempting to repair your device, contact your manufacturer. If your Tablet PC has a warranty, completing an unauthorized repair may make you ineligible for claiming that warranty. Hope this helps

Left touch screen doesnt work & doesnt send a load


your touchscreen is probably going out. Many of them will fail on one side before the other because the cable that connects the touchscreen to the unit itself will tear or malfunction. you need a new one.

N70 not charging


Here is a generic solution for all mobilephones!

This problem could be caused by either battery, charger or firmware failure. you can try the following to secure which!

-Try your mobilephone with another charger or connect it to a PC using a USB cable
> if ok? the problem is your charger!

-Try your mobilephone with another battery
> if ok? the problem is your the battery!

-Try your battery and charger on another phone
> if ok? the problem is your mobilephone/firmware :(

If you dont have access to other phone, battery, charger or USB-cable you can at least try the steps below:

1. Turn off your mobilephone
2. Take out your battery, Sim-card and memmory-card
3. Connect your charger
4. Put the battery in
5. Turn on the phone

If it doesn't help, with a little luck! you should get a USB-cable, back yor phone up and reset it to factory default and upgrade your firmware/software on the phone to the latest version!
OBS! You should only do it with a fully charged battery! or you could damage your phone irreversibly!!!

Touchscreen problem..


probably a bad touchpad or too sensitive settings.

Check Control panel then Mouse settings and look for sensitivity. you may want to turn off "tap to click" so at least you wont open things accidentally.

If it still is malfunctioning then the touchpad can be replaced probably $80-$120 for parts and labor.

Touchscreen malfunction


Hello Dean, and good evening. I understand the issue you are having and I'm here to help. From the way you said it stopped responding, it sounds like it could have possible froze, or something is internally wrong with it. If it didn't freeze I would contact Nintendo about this problem, and possibly get a refund, or mail it in and receive a new one. Hope this helped! Have a great day!
