[SOLVED] Laptop works only on external monitor

[valda84]

Hi,
I have problem with my laptop MSI MS-1757. After startup I cant see anything on laptop screen, as you can see on pictures. On external monitor I can see normal desktop. If I try move with display, it changes colours or sometimes desktop blinks. I checked the cable from MB to display and it is OK.
I cannot get into BIOS too.
Can anybody help me, where is the problem?

At any point when you try and boot does the laptops display work?

laptop display doesn´t work at any point. It works only on external monitor, after Windows start up.

My guess would be the either the display cable, which you checked on the motherboard side. Did you check the display cable going into the screen itself? it is possible that it is slightly loose.

Beyond that my next guess would be a screen replacement.
