Buttons on the touch panel do not respond when pressed.
Normally, the touch panel responds by just slightly touching a button with your finger. The touch panel does not respond when
- Using a glove or tip of a fingernail
- using a stylus, ballpoint pen, or pencil
Make sure when pressing a button on the touch panel that you are not touching anywhere else on the LCD screen with your other hand or another finger - the panel cannot detect multiple touches.
