Hiya

To help u i need more details...

For vibra: clean vibra pads on board, contacts on vibra motor, check motor with 5V DC if working... If failure remains check UI circuit NMP7xxx and via thru board ( from UI to pads )....

For clock: resolder or change B200 oscillator ( if clock is too slow or too fast )... Also if clock does not run at all or completely missing it should be soft problem: reflash firmware and good eeprom...

Worse thing it could be ( for both failures ) CPU....
