Strange Tx900 in N8210


all described i saw by NetMonitor
phone receive signal in 900 and 1800 stably i think (about -80 - -95)
when i try to call:
-in 1800 no any problem, phone allways connects and Tx power is good for 1800
-in 900 sometimes connection drops (Tx power is very little), but sometimes phone try to connect (pass some requests) and after go to 1900 and like i told in this band all is good
BUT sometimes phone connects good in 900 and Tx power is GOOD!!

i tried
-switcher changed/shorted for test
-change PA
-reball CCONT COBBA HAGAR
-change L553 from PA Tx out
-sw is ok
i dont understand, where can i search more?

maybe somebody has more experience is such trouble?
Thanx
BR
