DCS T70 LCD does work properly .I mean to say if i try to use one function another function gets started instead of desired function

Hi,

Based on the information you've provided, it seems that the touch screen panel is not aligned. You can try Calibrating the touch screen to resolve the issue.
Calibration option is in the Main Settings 1 Menu of the Camera. Calibration option enables you to perform calibration when the touch panel buttons do not react at the appropriate points where you touch. You can use the paint pen, touch the X mark displayed on the screen. The X mark moves on the screen. Once the calibration option is finished successfully, the touch screen should work.
The Calibration option can be done only if the Menu is accessible.
You can also perform a power reset before performing the Calibration.

Performing a manual power reset

Turn off the camera.

Remove the battery pack.

Press and hold the power button for 30 seconds.

Allow the camera to remain without power for 60 seconds.

Reinsert the battery pack.

Turn on the camera.
This should resolve the issue.

Thanks for using Fixya.
