T28 sometimes freezes & can't make call


Hello friends,

Have T28s on repair. Sometimes it works fine, but:
Have network signal but can't make call. When trying to call just display "connecting" and after that makes "bip bip bip" in the earphone and that's it.
Sometimes in the earphone I can hear one quiet "crack" sound instead of ringing to the other party. Sometimes the soft is very slow and freezies the phone.

I try to change PA, no results. Then try to heat the pcb with hot air, but no results.

Any sugestions?

Thanks for the answers...

regards,

Nicos
