Nokia 2100 delay in network searching - GSM-Forum

uu1dx · 03-04-2005, 14:52

Hi all!
Have NK2100 here, when I power on the phone - it searching for network about 90-120 seconds then found it and works well. No matter which mode - auto or manual search, with all SIMcards of local operators - the same. Replaced: HAGAR, T/R switch, all transistors couplers and filters around HAGAR, 26 MHz osc, RTC crystal, RX/TX VCO, reballed COBBA and CCONT. Nothing does help :-( Can someone suggest me what a hell going on?

At all this happened to ver 5.21 maded in Hungary ... just REPLACE cobba - and all be OK. In fact - phone work well, just slow registration - if you need to have fast registration - change cobba.
