W800i keypad 1,2,3,L-Soft - GSM-Forum

rct-remote · 04-10-2007, 02:47

w800i with Keys 1,2,3 and left soft menu do not work.

I assume problem is with EMI. I just want to bypass the 1 EMI circuit.

Anyone got Matrix ways to EMI so I can ypass 1 track over EMI ?

Check if no pads under the IC are broken off and check your keypad connector. REplace IC with good one. Any Keypad IC on a BB5 nokia will work on Sony E phones.

IC key near the joystick, repair or change it
