Midrange laptop released by Asus in 2014.

Laptop turns on, screen glitches out, then goes completely black.

Today when trying to turn on my laptop, the ASUS loading screen appeared, flickered, then went completely dark, emitting no light whatsoever. I tried shining a flashlight onto the display and couldn’t see anything at all. It’s completely dark.

The laptop itself runs fine. I tested by connecting to an external device. If the screen manages to stay lit and flickering long enough before going black, the picture will display just fine on the tv. Furthermore, the touch screen still works while hooked up to the HDMI. The display, however, remains completely dark. If I use fn + f7 to turn it off and then on, the screen comes back on, flickers, then goes dark just like on start up.

My graphics card is up to date and I don’t believe it is a backlight or inverter problem. Is there any idea what it could be and how I could go about fixing it?

Hi,

It appears that it may be either a faulty LVDS cable between the motherboard and the screen, a loose connection between the cable and the motherboard or the screen or a faulty screen.

Try gently moving the lid back and forth or try pressing on the left hinge (I think) to see if you can make the screen turn on or not. The LVDS cable passes through the hinge to get from the motherboard to the display unit and sometimes it can be damaged here.

Here’s is a link to a video that shows how to replace the screen in your laptop.

If it is determined that the problem is the LCD screen, usually the part number for the screen is stamped on the back of the screen itself.

Search online using the part number only in the search term to find suppliers of the part.

Here’s a link to just one supplier. It is only shown to give an idea of what the part costs and also to show that there is more than one type of screen available.
