HI,
Its time to take it in for service. Touch screen needs to checked. There is nothing much you can do apart from what you have done on your own. It requires special tools to open.
I suspect the Touch screen has to be recalibrated.

Thanks
Mandeep

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

Ipod touch screen is unresponsive but it makes sounds like normal


Fix an Unresponsive Ipod Screen
Many of today's electronic devices including cell phones, music players and portable game systems have a touch screen.
When a touch screen fails, it does not respond when you tap it with your finger or a stylus.
This can happen due to several reasons, such as a screen protector, dust or improper calibration.
You can often fix an unresponsive touch screen by cleaning it or resetting the device.
Remove the plastic touch screen protector sheet.
Some protector sheets are too thick and prevent the touch screen from responding to your touch. If you must use a protector screen, only use one that is licensed for your specific device.
Wipe the screen with a soft microfiber cloth.
Clean off any dirt, dust or fingerprints on the screen.

Dry your hands thoroughly.
The touch screen will not respond if your hands are wet.
Reset the device.
If your device does not have a "Reset" button, remove the battery, memory card or SIM card, then reinstall them.

Delete any third-party applications you recently installed.
Some third-party applications can cause your device to lock up or freeze.

Recalibrate the touch screen.
Look in the device's Settings menu for a calibration option and follow the prompts.

Press the "On/Off-Sleep/Wake" button if you need to restart the iPod touch, and hold it until the red slider appears on the screen.
Slide your finger over the slider to turn off the device.
Press the "On/Off-Sleep/Wake" button and hold it until the iPod touch turns back on.
If you can't turn off the iPod touch, you can try resetting it.
Press the "On/Off-Sleep/Wake" button while simultaneously pressing the "Home" button when you want to reset the iPod touch, and continue to hold the buttons for at least 10 seconds, until the screen goes black and the Apple logo appears.

Touch Screen does not respond to anything.


HI,
Have you tried to reset the Phone to factory defaults. To do this you need to keep the left and right (-) pressed and with the stylus press the reset button on the left. This would take the phone to factory reset.
If the screen still does not work its time to get it serviced and repair centre. Most probably it would have to replaced.

Thanks
