3315 Signal drop - GSM-Forum

.:::Dr. Cell:::. · 06-25-2004, 17:00

undefined Hi everybody. I ve encountered a problem with 3315 which was water damage. it got on by replacing ccont and heating the flash ic. and now the fault is dropping signals. i ve checked all the posts about this fault but nothing worked. i ve changed COBBA,Hagar, Vco,pa, antena switch but still same. signals come at once when i power on the phone and goes back before the lights turns off. But when i remove the clock cell(that black one) the signals starts coming and going but not stable. Plz suggest some solution. i ve also flashed the phone but the problem didnt solved.

Thanx in advance

Perhaps it is 26Mhz crystal. Are u sure PA is good?

As for me, you need to CHANGE PA. NOT resolder it! You need to change! Works for me most times...

why do you dry with heat?
why do you flash your phone ? when your phone is not funtioning properly?
step 1:
i do not know your heat level to your phone board?
try check your battery level.
check your antenna switch on your phone.
problem: you have flash your phone into network problem.

i have a suggestion for you.but,i need my answers for me to solve this problem.
