Earpiece or as some people call it speaker is placed on the top front of Nokia 3310. It is used for listening phone calls nothing else. All the other sounds come out of IHF speaker which is placed on the back bottom of the mobile phone. So if you can’t listen to the person on the other end of a phone call unless you open up the loudspeaker option from within the phone, your earpiece is faulty and you need to change it.
Earpieces are fragile parts and any kind of mishandling can cause them to break down. Normally changing Nokia 3310 earpiece is pretty straight forward since it is not soldered on the motherboard all you have to do is remove the old one from the external casing and place a new one in its place. But if that does not work or if your earpiece module is okay but you still can’t listen to a phone call then you are going to have to make the jumpers as shown in this diagram.

Here are Nokia 3310 earpiece jumper ways. Please study these diagrams very carefully before you start repairing.
- Now Check connection between each pin of on-board connector and speaker terminals (Pin of Connector with –ve terminal of speaker and Pin of Connector with +ve terminal of speaker)
- Now Check capacitor whether it is short, as this might also be the cause of problem.
- Check Audio IC’s coils with capacitor 1, if the coil is damaged replace it.
- If everything else fails then heat Audio IC and check, if that doesn’t work then replace it.
In order to troubleshoot, all you have to do is to follow the following steps:
Put jumper if it is faulty, as one of the reasons for this problem is that the phone heavily dropped or water damage.
Check the diode by using multi meter, if it is faulty then change it.
