Xperia z wifi , bluetooth and fm problem
My wifi is having this problem in combo - No wifi , no bluetooth and also fm is not working . In settings -about phone - status shows wifi mac adress and bluetooth adress unavailable .I tried everything restart , factory reset , software downgrade , upgrade . Do you guys know any other solution beside that. May be a harware problem occured . If it's a hardware problem pls guys help me ( coz my warranty is void , so I want to try myself to hardware repair ) . I've attached circuit diagram of xperia z in pdf format . Please explain where might be a problem if it is a hardware problem ? Where are the wifi chips, wifi antenna , possible hardware solution you might have. Please mark with marker in the circuit diagram.
Thanks to all developers and techs in xda
