mgl2006 · 11-15-2006, 00:36

My 1,4 & 7 keys dont work on my k700i. I've read the other posts on this but I don't know which components to rehot or replace for this prob.
Please help...Thanks.

Hi I have same Problem for k750i 1, 2, 3, *, #, OKkey joyRight and joyDown dont work and won't power off but the click sound works when pressed, seems to be a simple problem to fix but how do you check which IC is working or not (what tester to use), also what are the components called (reference to buy for replacement).

any HELP greatly appreciated.

Ok both of you need to change the keypad control ic which is located above right of joystick. The ic has 3 diodes to the left and 1 above and 1 below.

Hope that helps

Was that for the k700i or the k750? tried to find that ic but there isn't one with diodes top and bottom....

Thanks
