Member: 945648 Status: Offline Thanks Meter: 0 | Samsung S3 common problems I have here two Samsung S3, each with a very common problem upon Google search, but I haven't found a solution for any. Maybe you can help.. 1st I have a i9300 with the very common problem of people not listening well during calls. Already replaced mic without success. Works fine with viber, etc, also, if during call I press a bit harder at bottom of the battery people listen better. 2nd I have a i9305 with a dead lcd. No falls, no cracks, nothing, just went dead! Tried the i9300 lcd and works fine. Already cleaned contacts, lcd pcb and still persists. I want to try a light reflow on the lcd pcb chips but I'm afraid to melt the plastic.. Can anyone help me with either or both these issues? Thanks in advance. |

Member: 945648 Status: Offline Thanks Meter: 0 | Thanks d-artigo, Will try to re-heat mic ICs when I get home. Regarding lcd, could it be a bad chip instead of whole lcd module? Can I apply voltage somwhere in lcd module to see if it works? Thanks. |
