M17x Laptop Screen not working (stuck at black)

Hi,

It sounds like a loose cable connection for your LCD screen.  It's possibly a matter of checking the video cable connections and tightening them up.

It's not a simple procedure by any means, so unless you are experienced at computer repairs I highly recommend you get that system to the warranty repair service if at all possible.  There are many parts and connections you need to remove to get to the LCD screen.   

If you choose to do this yourself Dell won't be responsible for any damage you may happen to make to the system.  You do so at your own risk.  

Here is the user manual for the latest version of the M17x (check to make sure it's the same version of the 17x that you have before doing anything else) If you check out the section on replacing the LCD screen it will show you how you would normally take the LCD off that system and replace it.  You don't want to replace it obviously, but if you follow the directions it will show you where the video cable connection is.  You can check the cable to make sure it's making a tight connection between the LCD and the video card / system board.  Check the cable for crimping or any breaks, as well.  

Make sure you read the safety instructions and follow all instructions if you choose to work on your system.  

Again, I recommend that you take it to either a Dell warranty repair location or pay an experienced repair technician to do the work, so you are covered in the event of any issues that may occur, as Dell will not cover any damages from you working on the system.
