jessica, looks like (hard to say without actually having a picture) that you are talking about your DC jack. It is available at places [http://www.mytrendyphone.co.uk/shop/nokia-dc-jack-12696p.html|like this.] and you can download the complete service manual [http://www.filesonic.com/file/345854354/Nokia_6760_6790_slide_SM_L12_L34_SCH.ZIP|from here.] Hope this helps, good luck
