You don't want to fix that yourself. Apparently it's next to impossible to get the LCD cable rolled through the hinge properly (not to mention dismantling and reassembling the hinge without breaking it). I had this as well; my advice is to confirm that they can turn the repair around quickly before you send it in. Don't guess at whether or not the timing is right. Ask, and if they can repair it instantly, send it now.
I waited until mine went black and died completely, and the timing was terrible. I had to wait some weeks before there were LCDs in stock.
