cause u reheat or resoldered the PA only two things would happen either the phone would be ok or would be not.. I exp this kind of prob before... only just replaced good PA... that would be ok...
note: some PA.. like the black PA are easily bagdown if u reheat sometimes phone become short cause of the PA.. and silver PA is much better....

and by the way midnight is also correct u can check the V+ of the PA has a continuity.. from c570 to v+.. but in your case it has a signal dropping and coming back again.. it only cause two part the pa AND Audio IC or cobba.. for now just concentrate on the PA...P.S. i would like to know what happen after u replaced the PA.. gud luck mate

for u mate! based on my exp.. has signal after opening after and before the light turns of the signal drop.. here step by step tips for u!! just try it mate..
1.)first like midnight said before check the v+ to c570 near the PA.. if it has no continuity... by pass it.. phone would be ok... but if has a continuity...go step2.
2.)just reheat or resoldered the audio IC or cobba...???? test it.... still dropping signal..step3
3.)now u have to replaced a good audio IC... sp unlock and set faid.. test it again... u know that the IC is good but still dropping...go step4
4.)there are many solution on repairing that kind of prob....here's one of my final solution... first just reheat the PA and check weather the antenna switch pins are intact... if antenna switch is broken replaced it.. test the phone again.. still dropping...replaced the PA...u can do it mate gud luck

note:this is only based on my exp... since i'm repairing nokia phone...
