White screen, flex cable, back cover

[Giacomo_5]

Hi everybody

I replaced back cover and bezel of my Asus N56VZ
To do that I have disconnected and then reconnected the flex cable to the screen.

Now when I turn on the notebook the screen in completely white.
The notebook works if linked to an external monitor with hdmi.
I checked many time the cable, it seems to be well linked, but the problem continues.

What can I do now?
1- try to clean the cable with some solvent?
2- replace the cable?

Can you help me?

Thanks for the help.
Giacomo

Did you try disconnecting and reconnecting the cable at both ends?
