Help! Black screen but still have backlight

[ItsLame]

Hi, so my Asus g550jk laptop seems to have a problem.

In the midst of typing something, or playing games, or watching videos my screen will just suddenly turn black even though the backlight’s still on.

To turn it back on I would have to press Fn+F7 to disable the screen, wobble the monitor, then press Fn+F7 again to enable the screen, this brings back the display back to normal, however few seconds/minutes later it will randomly turn black again and I had to do the Fn+F7 again.

Does anyone know what the problem is? And how it can be fixed?


If you guys are wondering, this is what the F7 key functions as:

Most likely the screen is not working and may need to be replaced.

Try to connect via HDMI port to external monitor to see if the screen display is still working or not.

Plugging in it to an external display works fine.

I suspect it's a problem on either the ribbon/connector/cable, because when the display works, there isn't any dead pixels nor discoloration. I'm not really sure about this however since I'm not really an expert in these stuffs.

In my case the screen seem to be moving horizontally with some flickering.

Hence i did the replacement of the laptop screen cost $145 for 13.3" screen of Toshiba laptop.

Hardware issue with the display, possibly the flex , inverter portion. Head to Asus to get them to check it out.

Location as follows:

If you type things and you still hear sound, most likely will be the LED issue on the screen.
