Question about Compaq Presario Notebook
You can troubleshoot this at home, work, or a friend's house by connecting your laptop to an external monitor. On a Compaq you will need to hold down the "fn" key and press the "F4" key once they are connected to transfer the signal to the external monitor.
If the external monitor displays your normal screen view, then your laptop's screen (LCD) has failed. If it does not display and shows the same screen as your laptop, then your video controller on the laptop's motherboard or another motherboard problem is the issue.
In either case, you will likely need to send this laptop in for warranty repair.
