Hi, laptop was dropped onto carpeting. Now, on startup, "SONY" rasters for a few seconds and then the screen goes totally dark, but laptop continues to boot. Works fine on external monitor via VGA port. Screen does NOT appear to be cracked. Connections are fine. Inverter or backlight issue?

I have a problem with my hp laptop monitor's hinges, could you link where you were able to purchase those hinges?
Also, make sure you monitor's ribbon cable isn't missing any wires or that all of those wires are fully contacting.

Defective CCFL backlight may has the following symptom:
All these symptoms indicate that the LCD backlight lamp (CCFL Lamp)

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.
Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Have you updated the video driver?
If yes but problem persist I suspected it's your LCD screen is faulty and needs to be replace.
