This is a little tip for anyone having problems with their Sony Ericsson C905 where they cant hear anything whilst on the phone.
This is only if you cant hear anything through the earpiece, however it works normally when you have it on Loudspeaker...
There is a fault with the C905 ribbon flex, this flex connects to the phones, keypad and then runs under the screen and has pads for the phones earpiece to connect to.
There are 3 methods of solving the problem
1, If your phone is under warranty have an authorised Sony Ericsson service centre repair your phone for you, this is FREE and is the best option.
2, You can buy a replacement ribbon, for these handsets and change it yourself. It looks like the image in the following link

3, If you are able to solder and feel confident you can try the following fix, you need to make a jumper from the right solder pad to the leg on the transistor just below, use low res wire and be very carefull...
Remember trying 2 or 3 on your handset, if your phone is still under warranty will end up voiding your warranty so only do this if you dont have a warranty...
