You Tube Icon doesnt work

Hi, I needed to have the Youtube icon linked with an address prepended with http://www.youtube.com/channel/. I tried to upload a new icon and set it in custom links, but after the you tube shows two times. First one is the old icon where my like ( /channel) doesnt open cause it needs to have (/user) for the you tube address. If I change the CSS all the icons are not working anymore. So what ca I do to have my youtube icon linked with a youtube address which goes http://www.youtube.com/channel/…..?
Thanks for your help!
