    After I replaced my top screen of my DSL with a new one. And I finished up and turned it back on, sound was working, touch screen was working. Bottem screen was working, all buttons were working, microphone/speakers were working BUT! Geuss what, my top screen is all white. Why? How are the speakers (which are attached to the ribbon cable of the top screen) working and the top screen itself only showing a white screen? What could be the problem? Faulty screen? Or the connection between the top and the motherboard?

    Well. DS boots, so it´s maybe a faulty screen. You might want to triple-check the flex ribbon connection, for both motherboard socket and upper screen cable fitting correctly.

    Let´s say: A faulty ribbon flex won´t make your DS boot, you´ll just get a blinking white screen followed by a fast & complete shutdown.

    Here´s a tip: When you replace the upper screen, cover both sides of the ribbon flex with 3M scotch to get better flexibility & less risk of damaging the cable flex, because it means a dead screen.

    It's a brand new screen O_0 I am sure I also did not damage anything during the process. So basically check the connection between top screen ribbon's cable and the mothorboard?

    All I get is a blank top screen, bottom screen works perfectly...

    Sounds like the Top screen isn't quite connected correctly so yes just double check the connection between the top screen and mobo.

    Well.. are you sure you fitted the flex correctly? Doing some experiments in the past, I noticed DS won´t turn on if there´s not a screen properly plugged. It would be a good idea to ask for a LCD replacement now.

    as everyone else suggests you should chk the ribbon connection first, if you are sure that is connected properly then the next thing u should do is take the battery cover off, now either side of the screw hole are two holes inside those holes is a tiny screw which is an adjustment for the top n bottom screens, i cant remember which screw is for which screen but give them a slight turn n see if that makes any difference, leave your ds powered on while u are doin so, so u can see the screen adjustment

    You´re correct. There´s a screw located inside the motherboard which let you adjust the LCD screen. I remember it´d fix refresh rate/color of both screens--

    really? which screw is that? And how does a screw affect the top screen?

    And why would I order a new screen. THe one I just installed is brand new.

    Because, I´ve bought a few DS lite screens, and 1 of them usually comes with manufacturer faults/dead pixels/dead. If the calibration screw didn´t work for you, then it´s because of this. Or, you could simply get a dead NDS lite and replace some parts.
