Dear friend,

if you are able to find network in manual search and its drops it means mostly that problem from PA, check PA and near all components and voltages etc..
1)just resolder PA and check
2) change PA check it again
3)if stil drops then check in netowrk section all componects carefully with voltages if any componets look damage then clean it or replace it..

find the attachments hope those pics will help you lot..
