Nokia 8210 intermittent network
 

this 8210 has full network sometimes on powering on. After a few minutes it disappears and then reappears again. when the NW is there can make calls ok and be called. i tried to reflow board but the problem persists. Anyone help with solution?

Change PA

in most causes is problem in PA, antena switch, cobba, ccont. try rehot cobba and ccont and change PA.

Hi
Firstly clean antenna pins.
if not work:
Rehot@flux or change cobba. With that change PA.
Good Luck!
