Hmm, I have a simliar problem (posted http://talk.maemo.org/showthread.php?p=1128903) except my replacement screen doesn't work.. digitizer is fine.

If your screen is working doesn't that mean the slider is working? I don't know if I should order a new slider too since my digitizer is working.

Can we compare what we did to see if someone made a mistake? I put a photo in my thread
