I live in Finland. I think that you should connect Sharp Belgium. Here is Sharp Belgium contacts: SHARP ELECTRONICS BENELUX B.V. BELGIUM BRANCH [Belgium]

If you get lucky, they can get replacement screen (http://sharpsme.com/Page.aspx/americ...t/LQ030B7UB02/)
Or you can contact to www.merimobiles.com and ask for N21 replacement screen because they sold them some time ago.
I'm sure that you can't find replacement screen for DSTL1 from Belgium, if Sharp Belgium can't get it to you...
