Tosh Sattelite Pro C660 Screen divided in 3

[passete]

Hello guys,
i have here a C660-13C, PSCORE-00300EFR with a wierd symptom, the main screen is divided on 3 parts (check photo)?
When received, i was getting a black screen, flashed main and ec, and pc turned ON.
First time the screen was fine, after a second reboot, i got the divided screen, reflowed BGA, this machine is uma, only HD graphics from Core I3 ship.
Is this a lcd screen problem or GPU related ?
For 2 ou 3 times it rebooted fine, no divided screen
It works fine on external (VGA)

Just an idee.
I would gamble on the bios, being in conflict with the hardware (screen). If nothing else has changed. This is typical look, when you use a screen from a different brand. For example when you use a Hp screen in a Dell.

Screen is original (come with laptop).
I also updated the bios, using the bios update from Toshiba website, used the serial number to get the right/good bios.
I still have a doubt if the lcd is faulty ?

Hi, I would say the problem is with your screen.

You're right, that's a good way, because you didn't see the image before you change the bios.

I confirm that the problem is the LCD display, just tested another display using same ldvs cable and picture is not divided.
