Vibra Does Not Work; Keyboard Does Not Work; Sim Does Not Work - Nokia RH-13 Series Troubleshooting Manual

CCS Technical Documentation
No sound: Try using known good buzzer instead. If still no sound ->change UEM(D200)
Weak sound: Use Audio test in Phoenix to set buzzer parameters(frequency, strength). If
it doesn't effect to the sound level ->change buzzer.

Vibra does not work

Check spring connectors and C307.
No vibration: Try using known good vibra instead. If still no vibration -> change
UEM(D200)
Weak vibration: Use Vibra test in Phoenix to set vibra parameters(frequency, duty cycle).
If it doesn't effect to the magnitude of vibration ->change vibra.

Keyboard does not work

Check that there is no dirt between the dome sheet and the PWB, also check that Z300 is
properly soldered and the corner mark is located in the right place. If the keyboard still
doesn't operate normally -> try to use Keyboard test in Phoenix to see if the pressed key
is identified. If not ->change UPP(D400), then if this does not help, also change the
Z300.

SIM does not work

Check SIM reader's spring connectors, C390 (VSIM 3.0V) and R388. If SIM still does not
work then probably the UEM or the UPP is broken -> change first one component and
check the phone.
