Touchscreen does not work

Read the screen it should tell you that too many attempty have been made to open the lock and that it will be enabled after so many minutes..

Probably it won't be usable because the sensors on the screen is corrupted. You need to replace it with a brand new screen.

Two thing can cause this. If your unit is running firmware version 5.3, this version has a bug where the touchscreen will work for about 5 seconds then the unit will lock up. Updating the unit to version to version 5.4 will fix the problem. More info can be found here:

If you are running firmware version 4.9 or 5.4 and the touchscreen still does not respond, then the touchscreen will need to be replaced. On the Nuvi 7xx, the touchscreen may be soldered to the LCD display, so if you don't have any soldering experience, please have a professional replace the touchscreen. More info can be found here:

I have a Dual xdvd8180 dvds multimedia reciever 7" digital touchscreen in my car and it worked fine for the longest time but now it wont read any of my cds.. burnt or original discs.. nor will it read dvds.. i tried cleaning it with a disk cleaning kit and it wouldn't even play that without skipping..idk whats wrong.. any help??

Go to contacts,then view,then shift to name and number ,.. you'll be able to see both name and number simultaneously.

please mension the problem

Switch the phone off, look at the back of it, remove the back cover, remove the battery. you should see two copper colored screws, remove the screw, remove the flip, replace the flip with the small cover that you should have recieved with the phone, replace the screws, replace the battery, replace the back cover, switch the phone on and operate as normal but without the flip. A hint though, you touchscreen will get dirty very quickly

I would like to ask a couple questions that might be of some use.

First, does the same issue occur when using the phone with the flip closed? That is, can you use the jog dial and keys on the flip properly?

If the phone works fine with the keypad and jog dial, then you should be able to try to recalibrate the touchscreen.

To re-calibrate the screen:

1. Select Applications tab
2. Select Control Panel
3. Select Device
4. Select Display or Screen
5. Follow the instructions on the screen.
6. Select Yes or No


Second, if you turn the phone off and on again, with the flip open, does anything load by itself, or does the touchscreen react as if something is being pressed?

This may indicate that there is a problem with the hardware.
It is possible to purchase a new touchscreen for under $100 from a few parts retailers such as http://cnn.cn .

It may also simply be a glitch or bug in the software or firmware OS. In this case, you can try a master reset or updating the firmware using Sony Ericssons update service (not compatible with Vista for the P910), or you could use a third party firmware utility such as from DaVinci etc.
If you choose any of the master reset, firmware or update options, you will lose ALL user data on the phone, so you should back it up before you proceed.

There has been many set-backs with this particular model smartphone. My sugguestion is to return while you can a go with the Treo 700. It's much simplier and realiable
