Red face Speaker issue

I have had a good hunt around but nothing sounds like this problem. Sorry in advance if its a stupid question or has been answered elsewhere.

I got given an AT&T Tilt by a friend. He told me the main speaker at the rear was bust and it needed a new one. I checked it out and got the service manual to see if there was a bad connection. Then I ordered a replacement speaker from Fleabay. I fitted the new speaker but it made no difference at all.

Basically I get clicking noises from the speaker at low volume and at high volume it sounds like the speaker is blown or highly distorted even though the volume is barely audible.

I just tried flashing a new Radio ROM but everything else is as I got it.

Currently it has on it...

ROM Ver: 3.57.502.2 WWE
ROM Date: 07/17/08
Radio Ver: 1.71.09.01
Protocol Ver: 25.75.40.02.eMo

Yes I am a Noob to this stuff. I have spent a couple of days looking for a solution to this. I almost hope I am making a rookie mistake and its a simple fault. If someone can point me in the right direction please.

Thanks,

Fangio.
