I found Nokia 6680 error at Bluetooth... (Operation failed)

Measurement :

Check Vio at c6035 = 1.8v normal
Check Vregout At C6036 = 0 (It should be 2.8v)

Analisis....

Vregout Regulator (N6031) is damaged....

Step.... Make Jumper between Vaux (C1470) 2.8v to Vregout C6036

Result......

Case Nokia 6630 Signal Problem....

Object :

Step :
Searching manual on phone at setting, Network...... Manually...

REsult : No Operator Found

So in this case the problem is at RX Part or Receiver

Measurement step....

1. Check Rx i/q di J7508, J7509, J7510, J7511..... Not Good datas... so the problem is around RF Ic not rap problem.. cause the data come from rf ic to Rap..
2. Check Control Vco at pin out cp at rf ic... Result is Noise.. so the problem is at CP Out line (Control VCO).. at BB5 phone the problem is always damaged at capasiror 2n2.. so i change it...

after change.. i check again and its not noise anymore....

after that i search manually the network again.. result.. all operator is found...
but after selec an operator its cant acces.. its show NO Accest at display...

so problem now is at TX (Transmitter).. RX Problem is solved....

Next step....

Check Control VCO for TX at cp out line at Vinku result.... No line...
its mean VCO for Vinku not working....

Next step....
Check VCO Coltage at c7555... No Voltage... its must be 2.8v
Check vreg2 at C7548 No Voltage too its must be 2.8v too cause its be at same way with vco voltage...
Check way between c7555 and cc7548 result the way is OK...

Summary.....
Damaged is at VCO Voltage.. its not be 2.8volt.....

Solution....
Find another voltage... example Vreg1 with same value....

Make jumper betweenVreg1 (C7543) yo Vreg2 (C7548)...

after make jumper I check control VCO is ok... and not noise....

Turn on the phone.. and the result is....

Best Regards...
