K700i network problems - GSM-Forum

czoran · 06-07-2007, 09:32

Hello,

I cleaned one K700 after water damage and everything was working fine for several days.

Now it can register to network without problems but can not make or receive calls. When I try to dial number it just return back to main screen. When I try to call it from another phone, I am getting "user not reachable" or "user has switched off" announcements.

Tried to clean it again, reflow, reflash. Nothing helped.

Any hints?

Thank you.

pull out the antenna switch and connect the first,7th and the 13th legs of the antenna switch(see previous posts on antenna switch bridge for k700i).do not replace it.If not ok ,then change the pa.

Heat pcb on a 40 watt electricity bulb for about two hours.Change position every 25 minutes to avoid damage and to allow all parts of pcb are heated.Reason :I still think there is some water locked in the major components especially the antenna switch and the pa.All the best.
