    Hello,

     

    First test:

    Do you have the same issue with an external monitor or LCD TV in using the VGA or HDMI port?

    [Fn]+[F5] - Display toggle: Switches display output between the display screen, external monitor (if connected) and both.

    If you press on the bottom of the LCD bezel (<--  -->), do you see a difference?

    Hello,

     

    Sorry for the delay...

    1- Remove the LCD bezel and check the LCD connector (LCD cable).

    2- If you find anything wrong, you'll have to change the LCD panel with the inverter.

    Hi laurent, you said you'll have to change the LCD panel with the inverter. 

     

    Does it have inverter ? I think only CCFL panel includes inverter this panel is LED ??

     

    and model number is  : CMN N173HGE-E11

    Hello,

     

    Your LCD panel is a CHIMEY INNOLUX N173HGE-E11 (LCD + LED backlight).

    You'll understand in reading its datasheet (page 7/37). The electronic board is "fixed on the panel.
