This is a common problem one the Sony Ericsson C905, there are 2 possible fixes for the handset.

The fault is caused by a faulty ribbon, the ribbon connect to the keypad runs under the screen and goes to the top of the handset connecting to the earpiece, it also has the 2 buttons built in (2 side buttons at the top of the phone.)

You can either replace this keypad, as its a common fault you can get these quite easily looks like the following image

The other fix, which is if you dont want to spend any money, but only if you can solder and are confident enough to do this, is to create a bridge from the right earpiece pad to the transistor just underneath, this is shown in the image below... Use small low res wire

Tip

C905 - Cant hear, earpiece problem.


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
<a href="http://www.findmethatphone.co.uk/fixes/c905flex.jpg" target="_blank">C905 Flex</a>

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...

I cant hear when i call or receive a call


Dear, i have faced the similar problem, basically the speaker of your phone is not working properly, it is out of order and need to repair. You must visit the repair shop. This is not a big damage but disturbing one.

Good luck in correcting your problem.
Best regards.
