    Aspire One 772 black screen. External VGA ok.

    Need your help guys!

    Original problem with this is cracked screen. I then replaced the LCD screen. All seems to be going fine then the screen gone black with backlight then completely black. I tried plugging it in an external monitor and it works fine.
    -tried disabling AMD graphics driver.
    -Win+P does nothing.(extend,duplicate,projector only, PC screen only)
    - +LEDVDD is present but +LCDVDD is not. it seems the on signal is not working together with backlight. i tried jumping LCDVDD to 3VS rail but didnt work.
    - tried updating the bios thru bootable DOS.

    That's what i tried. please help me.


    Thanks in advance
