I have a Dell Inspiron 9100 notebook with a dead LCD, however, it has an audible post and boot to Windows XP. External monitor hook up did not work.

Some history: This notebook initially had a problem of no charge on the AC adpater due to loose wiring, then ultimately a dead battery. The adapter is now repaired, but the display is black. Could this be the Inverter? Any suggestions please? Thank you!
