YeTi · 05-16-2003, 00:29

Hi,

i´m beginnig to repair phones and i have some questions that i would like to know :

i have a hot air station 902+, i put the temperature at 300ºC, i think is right ??

i have a 8210 with no network, when i switch it on, he have network for 3 seconds and then no more, i try to search network manual and it get all but takes a lot, is PA or antenna switch problem?? if its near the PC monitor it blink sometimes like if im receiving a call?

the cover of the zone where is PA and antenna switch must be taken to change/ repair the components in 8210, wich is the best way to take it out?? and the best way to put it on the right place again?

Sorry for all this question, but i already read old posts and i´m a little confuse.

Thanks for all replies...

You used hot air station 902+, i put the temperature at 300ºC, it is right enough

Your problem :
For 8210 with no network, when u switch it on, only have network for 3 seconds and then no more, u try to search network manual and it get all but takes a lot,

Solution :
I think there is diplexor (antenna switch) problem.
Cause if its near the PC monitor it blink sometimes like if im receiving a call, so the phone ''can transmit but cannot received ok'', means the PA is already ok but the duplexor is not ok.

To change/ repair the components just easy like plug and play.. but be carefull... more safe if you using flux for take the duplexer...

Hi YeTi!
Firstly change Pa.
And if not work,
CHANGE COBBA!
Antenna Switch damaged=poor or no signal!
TRY IT!

YeTi,
if your PA and antenna Switch is replaced then:
try to see that 32.768Khz sleep clock by run ring tone, see it slow or you can put a charger check charger bar run speed !
if it is normal, then you go to replace 26Mhz

first replace PFO and if it doesnt work than change antena switch. work carefuly and try not to demage any litle components around PFO and switch. That should solve your problem for 99.99%

You have problem with internal freq. sintesis. Chek 32.768kHz qarc if it is o.k. replace 26MHz oscillator.
