Or replace the VCO in the middle section of phone.<br />3. Maybe antena switch. you can replace it with 1018 switch<br /> <img src="smile.gif" border="0"> <img src="smile.gif" border="0"> |

Member: 5379 Status: Offline Thanks Meter: 0 | first u have to try with a lamp antenna (the one which will flashing light when received signals), if the phone experience the "!" sign, the light will only blink once and once (and that's mean the PA is not broken), if that's the problem, u have to change the PMB 2906 BGA on 35 series |
