| Hi, Before you change antenna switch, are you sure that is the problem? what happened to cause this problem? is it blocked? have you tried turning off 3g? does it search for carriers? |

| @dog68 thank you for your replay the Singal is very weak, it looks for carries and sometimes it had a connection but only 1-2bars (same carrier other 3gs some place full bars) so I think it is the antenna switch...the problem which i have now is that the small ics moved on the top and the main pcb under the 3ics not moved  only if i remove the 3ics and after that remove the pcb of the antenna switch so how can i do this? please help |

| You have hot air station etc? just take off from board, then reseat ic's on top of switch, and replace, or use switch from old board, the ic's come off because heat too close to switch. |
