Member: 7751 Status: Offline Thanks Meter: 74 | T28 call dropping. funny one Had a T28 yesterday with the following fault. Power on, finds network, 3 bars. after 3 min "No Access", but in those 3 min if a call was attempted, when it starts connection after 3 sec, it just dropped the call with a "beep". Following have been changed in the this T28, in sequence like this 1 : PA 2 : Antanna Switch 3 : TX mixer circuit 4 : RF signal processor <--- This one is normally the culprit as I have noticed fromn other phones ( Made by Ericsson ) 5 : 13MHz Crystal Module And you know what after all this, the SAME fault still remains, aint that a bugger !!! Anyone had one of these before ?? Any suggestions ?? Regards |
