Asus K43E power on, but screen displays nothing

[cheryl2017]

My Asus K43E laptop now is in problem. It can turn on (Power on is light, harddrive is light, LCD display is light) but nothing is displayed on screen. Connecting to another desktop still works fine. I guess it's from LCD. Please help me to fix it! Thank so much!

Try this...

1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.

NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

the ribbon cable caused the problem. I replaced by new one. Thanks so much.
