Did you check the E61 on the PCB??

1 2 I___I | | --- I I I 3 4 5

Pin1: -> "C"-"3"-"5"-"0" Pin2: -> "6"-"7"-"*"-"9" Pin3: -> "use"-"DOWN"-"1"-"2" Pin4: -> GND Pin5: -> "up"-"8"-"#"-"4"

I send you Mail with photo of it.

Check all the lines of PCB from one side of PCB to another.

Hi Correct me if I am wrong but the User interface IC is for the LEDs, buzzer and vibra. The matrix for the keyboard is conected directly to MAD2 as follow:

Row0 - pin F1 Row1 - pin F2 Row2 - pin F3 Row3 - pin F4 Row4 - pin E2

Col0 - pin C3 Col1 - pin C4 Col2 - pin D4 Col3 - pin D3

Row0 is used only for power on. So you have matrix 4x4 which is 16 buttons. In your case you should look for the fault somwhere else. I have no idea and I am realy sorry. Could be the MAD2 faulty, but there is a chance to change it. Just check it in <a href="http://www.gsmcity.de/ubb/ultimatebb.php?ubb=get_topic&f=45&t=000459" target="_blank">http://www.gsmcity.de/ubb/ultimatebb.php?ubb=get_topic&f=45&t=000459</a> if ChamKute give us the Know How.

Best regards Daniel
