Hi.

I have cleaned the PCB of both phones and they came back to life, but with a big problem, one of them doesn't catch signal at all and the other one catchs very poor signal and looses continuously.

Any idea?

Thanks.

Trier,

YOU can try test :

1: PLL for VCO loop, from Hager to VCO , test it CH 60 , 2.75V/219HZ

2: CHECK AFC at COBBA to TXCO , 1.2V

3: RSSI from Hager to COBBA IP/QP level
