i dont understand the ic you mean and secondly i need all the possible solution to 3310 nokia network problem

i need on board solutn and running of wire for nokia [all] network problem.
i need solution to nokia 6108 charging problem

Wire solution u mean Jumper trick ?? replacing duplexer (antenna switch by wire isnt good repair) otherwise u will lost 1800mhz frequency. When u wanna hint to repair nokea 3310 signal, u must explain ur problem very well. coz there are too many parts in phone which can be damaged, and phone has no signal. (PA, COBBA, DUPLEXER, 1stVCO-crystal, Haggar, Filters...etc. even it can be broken track and so on.) Explain ur problem better. We will try to help you. Nokia 3310 signal problems aren`t same. U can not use only one solution to repair all without signal 3310`s.

!!!And jeerich please post nokia network problems to right section . !!!

Hi I have same problem on 3 3100's. Iv'e changed the 1851 and transformer but still same problem. The 1851 is same ic which is used on 6600 phones but I cannot find any relationship between the 2 phones.

Any other ideas pls??

btw 3100 had no liquid damage before, coil was s/c before replacing (good).

Fault must be in backlight trigerring section, that is, a broken track which sends signal to 1851 to switch on b/l.
