easy fix
If you can get them apart i think i may be able to help. the one that wont turn a disk, it may have been dropped or something by one of your nephews, and the tiny spring inside the door sensor got knocked loose. open your cube and with the control ports facing you look to the top-right. you should see a small card with two little black boxes on it, and two levers sticking out. The tops of the boxes pop of with a lil prying (use a small flat blade or screwdriver) and check the springs under it. they may be turned sideways and not getting a good connection. for the other one, its proly the laser needs to be recalabrated.
since this is my first post it wont let me send you a link, so i just attached the files below.
hope this helps XP
(BTW if the person who made this file i posted happens to read this, sry i didnt really have any other way to show him. im a new user and it wouldnt let me leave a link)
