Title:

Why does my display not come on after hearing the computer boot?

Text:

I can hear the computer boot and see lights on the keyboard, but never get a display. I can hook up an external monitor and get a display on the monitor, but nothing on the laptop screen.

Device:

MacBook Pro 15" Core 2 Duo Models A1226 and A1260

Status:
