AN525-42 laptop display not working, external HDMI works fine

Hello,
Recently my nitro got invaded by ants : (  My daughter noticed it after starting to play World Of Warcraft and it shut down? crashed? black screen? then saw ants.  All I got to see was a laptop without display.
I gently opened it up and vacuumed the little ***** out.  NOTE: I have been building pc's since 1980's so I was careful and pretty sure I didn't damage anything.  I did disconnect the battery during this process so the bios might have been reset but I can't imagine a setting to disable the local screen...
Since then there has been no display to the local laptop screen although it runs fine via external hdmi.  I just tested WOW at 2K settings and it is running at 90 fps - on the rx560 -  not the vega.
Still no display (no back light so no power?) though and windows is only showing the external display, not the laptop one.
I guess an ant perhaps shorted out the power?
Anyone got any other ideas?  I have re-opened it up and can see no damage or disconnected plugs.
thanks in advance
Shane : )

    We need to determine whether it is a hardware or software issue..   Turn off the computer.   Tap f2 while turning on the computer.   It will go to bios.  Please stay on the bios screen for 30 mins.    If the display is looking good on bios on your laptop screen then it is a software issue.   If the display is not looking good on the bios screen then it is a hardware issue.   

    If it is a software issue try the following steps..

    Try windows x 
    go to device manager 
    expand display adapter
    right click on display driver - uninstall 
    Restart the computer 

    It should work fine.. 

    If it is still not working 
    Uninstall the display adapter from device manager 
    Don’t restart the computer. 
    Go to support.acer.com 
    chose your country 
    type snid or chose your model 
    go to drivers 
    Install the display driver 

    It should work fine..
