7600 CPU problem - GSM-Forum

sasko2 · 11-20-2004, 15:20

I repaired 7600 with problem on 1,5,9,mnu,left soft key. They some works some don't works.
after measurements I found all thay are linked with same ppin and it's located at left bottom side of keyboard conector. I clean and link any links on keybord and check connector, but the problem wasn't solved. Then I try to reball CPU and when I paunch it in PCB are 2 points missing (S1 and S2). Now I don't know where they going..

Does someone has chip pins description or servis manual or someelse to solve the problem with CPU.

Thanks in advance
Best regards Pano
