Hi,

Please power phone up with battery and PCB ONLY!! take phone out of housing and power up...

next measure the voltage between the two contacts of the 0 key, if you get 1.8v then the problem is with the silver domes...

if you dont get 1.8v then the phone is faulty, perhaps track damage due to liquid damage?
