8210 some fix...but pls HELP

[Smoove]

I have changed the Ccont to my phone ..and it does not go off anymore...but it will go off only if I try to dial or if I insert the sim and it tries 2 search for network.
Still no network signal.
I have opened my mother board and I see a tiny chip ( antenna switch - located in the upper right) that looks like burned, but the guy from the service shop said that it isn't the fault of that chip...
I think he might be lying...what do you think????

Please help...give me any suggestions on what i might change...execpt the MAD2 cause it's glued..no change to change it.

Thx

why did you change the CCONT in the first place?

[Sam_digital]

yes it can be antenna switch , also can be The PA chip next to antenna switch ic , but first try the antenna switch .

so you have changed the CCONT and stll no signal?what was the problem then? NO SIGNAL? if yes you have gone so far..... with NO SIGNAL:

1. check your IF 1st FILTER then
2. your 2nd IF filter
3. your UHF and VHF oscillator
4. your PA's
5. Antenna switch
6. CCONT
7. COBBA

see what i mean CCOnt is secont to the last. try your antenna contacts too. search with a full battery, that the cause when it is shutting off when you search for a network. searching for network takes a lot mA of your battery.


GOODLUCK
