Storm 2 9550 keyboard

[ Edited ]

Hello. Sorry for my bad english Smiley Happy
The keyboard on my cellphone doesn't work properly - two buttons "finish call" (red button) and one button near - "back button" - they don't answer on my commands. All the other buttons works fine. It's began from this - when i have pressed one of 4 button's ("answer call"; "menu"; "back"; "finish call") - one time! - it clicked 2 or 3 times; and it looked like i pressed it 2 or 3 times. For example - i want to call somebody: i'm pressing green button "answer call" to open the phone book or last calls! - i pressed it only one time - but the result - the cellphone calling first persone from the adress book - it means that button pressed 3 times.
Now this two buttons "answer call" and "menu" seems working good and buttons "back" and "finish call" doesn't work.

What should i replace - sensor screen or the motherboard with "4 piezo elements" under the sensor screen?
