7610 network ...what u say hAAAh

[pdapower]

i have a 7610 with no network at all ...on search it says no operator found ...it gives this mess after 1 min 6 sec sometimes 1 min 2 sec ,, nearly about 1 min approx...

1 ---i tried changing its rf ic from 6260 pcb ..the no. of these ic were diff but many of them said tht both r same i found they were same in design also so i changed them
2---i changed antinna switch from 6260 pcb only
3--- changed pfo from 6260 pcb
4--- changed white filters and two small ic above antinna switch (1 is leg ic and 1 is 4 print ic)

this 6260 parts are all ok coz this 6260 pcb was damaged by me only 2 days b4 and earlier it was having full network so i guess all network parts are ok

but now m totally confused what more shld i do coz their is still no network at all some1 says change ur rf ic some1 says tht change ur antinna but plz all heros tell me wht exactly shld i do ...... help me urgent

[pdapower]

Is Their Really No One To Solve My Prob .......5 Days Have Been Passed And I Have Not Got A Single Answer

If it takes a long time before you get the 'no operator found' message, it is in most cases the switch. If you get this message within a couple of seconds it is pm file or RF IC.

So try another switch.

first try this antenna switch trcks ( if not ok follow my solutions )

1, re hot the hagar ic ( if not ok follow 2nd solution )

2, change the crystal ocsillater,it is near hagar ic. ( if not ok follow 3rd solution )

3, re boll the hagar ic ( if not ok follow 4th solution )

4, change the hagar ic ( if not ok follow 5th solution )

5, change the uem ic


be careful if you have experience to Rebolling and changing ics then follow the solutions, if you dont have experience to Rebolling and changing ics please dont try the 3rd and 4th, 5th solutions thank you.

Have you checked the "RXI/Q" signal sir....? Dont waste your time just only to change one and another IC. Many people do like this, they depend on their LUCK. They hope "LUCKY ****" in repairing hanpdhone. Its time to MEASURE with your Osciloscope, Frequency counter, Spectrum Analyzer.....
