Can you tell me more symptom for your phone? did it drop in water before? have you use the external power to check the operation current? have you use the scope to check the 13 MHZ out put? <img src="smile.gif" border="0">

Hi Misa!!

Check your vcore and vbb voltages on mad2, measure resistance between vcore and gnd, vbb and gnd, and vcore - vbb resistance, if any is short circuited the mad2 is dead, if not check ccont, and hagar, if there is no 13MHz clock from hagar to mad2 phone is dead also... Phone will work without the cobba ( contact service on display) ... Hagar and ccont are most important ...

 Best regards ...
