Does this look like a broken LCD, damaged video cable or something else? It doesnt look like a broken LCD issue to me.
I dropped my laptop from about two feet high onto carpet. Now the LCD shows mostly solid grey with only a few horizontal lines that reveal part of the image that should be displayed (HP logo).
It will not boot to windows but I cant see the bottom of the screen to troubleshoot that issue.
I have tried connecting an external monitor, but when I press Fn+F4, it will not change. The F4 key has the monitor logo but when I press it alone it still wont change. I have tried several different methods of changing to the external monitor including closing the laptop, but none of them have any affect.
I suspect that the external monitor will not work because I am stuck in the POST.
Before I spend the money on a replacement LCD, I wanted to get another opinion.
I would hate to replace the LCD and still have the same problem.
Thanks in advance....
Thats DEFINITELY new screen time, but it SHOULD work with an external...remove battery, press power button for 1 minute with no charger or battery connected, then reassemble all and try external again...you ARE pressing the CORRECT FUNCTION KEY for the external of course ?
If still no external , you need a new screen PLUS whatever other damage you did
Laptop repair shop for diagnosis is my best advice if so...
The F4 key has a symbol like this. |[ ]| that is clearly for the external monitor.
I tried your hard reset suggestion but still get no display on the external when I press F4 or Fn+F4.
It just wont work in POST.
Now I'll order a replacement LCD. I have changed them before, but never saw one look like this.
They usually have pattern like a broken mirror or pane of glass.
