Nokia x6 no network

[evaireland]

Hi after changing digitizer on nokia x6 network gone, disassemble and reassemble few times the problem still there all seems to work fine except for the network,try to find netork manualy from the menu couldn't find any, I've checked the antenna conection ( two pins at the bottom) looks alright.

any idea what could be the problem???

the solution that may help and guide to repair Nokia X6 having a No Network Signal reception. If ever tried to restore and update the device firmware but nothing happens, this solution shows the corresponding RF circuit of Nokia X6 PCB board that might something wrong, faulty or being damaged.

Repair Tips:
1. Apply and supply voltage to the PCB board using desired DC regulated power supply voltage of 3.7 volts. Check the supply voltage from the cellphone's battery through to the corresponding components highlighted in red color, these are battery supply voltage filter coils that being feeds to RF circuit components. IF there are no voltage readings on that areas, check the continuity of the battery positive terminal on that certain parts. Apply jumper if the line is cut or open. check also the filter coils and replace if found damaged.
2. Check and measure the secondary voltage output from the RF DC to DC converter chip highlighted in orange color. If there is no voltage readings on that spots, rework or replace the DC to DC converter IC.
3. Check or replace the Clock crystal oscillator. (VCTXO)
4. Rework or replace RF Power Ampilifier IC (PA)
5. Rework or replace Front End Module IC (FEM)
6. Rework or replace Radio Frequency IC (RF IC)

hai guys,

my NOkia x6-00 8GB has the same problem... it sometimes not detecting network. but recently i found out that if i tap the phone on a hard surface by the top- left portion of its back side-- its screen should face towards us-- that is exactly the back portion of the writing "X6"... it starts working... its some hardware problem-loose contact like.... make sure that your phone is in a carry case before tapping the handset.....

please mail me if anybody know how to make it working without this tapping...

thanks and regards

its also useful to eliminate the on board serial antenna conector , mostly that's the fault's source

ok,, i'll try that................................
