Up side 4 key doesn't work?a55? - GSM-Forum

gsmsalers · 08-29-2003, 22:10

Hi.
I don't know is it software or hardware problem it happened to very new handsets. After unlocking many pieces a55 with cut pcb line near cpu methode we found 3 pieces of a55 don't work upside 4 key. "Menu,cancel,up,down" keys not working. I don't know before unlocking those keys were working or not? Does this pcb line cut methode has side effect for those key? Or I cut wrong line with test test line? Is it hardware problemm or software? How to repair? If it is hardware trouble how to repair it? I need pcb layout. Other 10 pieces are working okey.
Thanks for attention.

Pls someone help us,
I too, I tried to cut wire with pix from spunlock, but phone not unlocked and phone now dead.
Pls can ppl help us to tell us exactly where to cut and where to reconnect to get the phone working.
The phone for me doesn't respond to the Red power ON button at all.

Pls SOS.

thanks

You have cutted to deep, under test line is power track.

i advise you to trace the line feed these keys from and to the cpu it might b infected if you check that it have prober voltage

blah · 08-30-2003, 23:29

Hello, I'm thinking that not working keys are not because of badly cutted track. I checked voltage on keys plates on PCB :-) It's same as on other keys... I think that if track were cutten badly it shouldn't have correct voltage.

Anywhere some can post picture how to make jumper? then all of us can repair them. I need pin description under cpu.
