Toshiba Laptop Screen Problems

[johndoe201002]

The screen on my laptop suddenly shows incorrect colours as shown in the pictures. I went into the BIOS and the situation was the same. The laptop did not fall or face any physical damage prior. Its model is TOSHIBA Satellite C855-S5194.

Sounds to me like the display is going bad, but I would try the following to test it out first...

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.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.
