[.:SARCAR:.]

ok mate , I think u already clean d pcb very well before open this thread!!

lots of things to be checked.............

1. check or change L7510 , it's a main coil to input voltage from battery
to PA
2. check or change C7507 , it's a 10n chipcap to vco input (u may also replace vco G7501 then check)
3. reflow or reball rf ic N7505 , because it may eaisly damage due to water
4. resold or replace duplex filters Z7540 & Z7541

post d result

Problems can be found wherever there was water.
Most often leaves path on the board. Watch the scheme to check the voltage ...
