1.I've rehoted the PA....the problem is still here... 2.I've rehoted RF power end stage (MOSFET NE5510379A), the phone found the net, but when i tried to make a call the antenna symbol becamed low and call failed....The net was lost as at the beginning 3.I've changed the PA and RF power end stage (MOSFET NE5510379A) from the working phone - the problem is still on it's place :-((( 4.I've soldered the PA and RF power end stage (MOSFET NE5510379A) from the broken phone to that working - the working phone became alive and succesfuly found the net...

So!! In my case the PA and RF power end stage (MOSFET NE5510379A) are good!!!!...

Where can be the problem then? Please advise me!!

Best regards Corban
