As you said your touch screen doesn't works properly it means that you are able to work with the screen only the response of the touch screen is not so effective.Then you should not worry.You have just re calibrate the phone for more effectiveness.
The steps to recalibrate is quite simple Go to control panel menu-Setup wizard tap 'YES' before cancel appears.Do this until you see 1,2,3,4 numbers blinking...
Mostly this will solve the problem.Then you have to see the sensor or the Keypad IC fault.and replace it accordingly...
Please do rate the solution if the issue is resolved or post a comment for further assistance.
First, upgrade the software of the phone.
After the upgrade, the setup wizard appears; complete it, and start it again from "Control panel", "Other", "setup wizard": now, just press the next button until 1 2 3 4 appears in the screen: don't select anything else, just the next button, or the calibration screen would not appear.
Hello, Try calibration! else, the only way is to change it, i did it my self, i think it would not be difficult if you have done similar things! you can buy it for a reasonable price on the net. Good luck
go to control pannel >>>>other>>>>setup wizzard>>>>>>keep it next next then u enter pen calliberation menu u will see 4 dots at 4 corners of ur screen touch on it exactly ur touch screen works properly
Touch screen not working for sony ericsson P990i Mobile phone
When I hit the center some part above gets highlighted and selected and the botton part where the taskmanager and battery icons are present does not respond to my taps ... what could be the problem,,, kindly help me solve the issue.
I encountered the same problem but was able to fix it. Just don't know if it's just temporary. Go to tools, control panel, other, set up wizard, tap yes, tap the second button before cancel, keep on clicking to the right direction until the numbers 1, 2, 3 and 4 appears. Tap the center of each number until blinking stops, save settings. For the first few steps you may use the jog dial found on the left side of the phone if the touch screen does not follow your tappings.
