Plug it into an external monitor and tell us what it does, so we know if there is an issue with the board. This lacks a GPU, so it’s typically going to be the screen but in some cases, it can be due to a bad motherboard.
The next thing you want to try is resetting the [http://support.apple.com/kb/HT3964|SMC and PRAM] and see if it helps.
If it turns out to be the internal only, it’s either due to a bad cable, screen or motherboard. The cheapest fix is to try and reconnect the LVDS cable and work your way up to the screen. If neither the screen nor a LVDS cable help, your board needs repair.

Next, i'd look at the display being at fault, this is intended to be replaced as one unit, but you may be able to disassemble the assembly, depending on what MacBook it is you have, i can't say for sure until I know

If that does not work, it's a GPU issue where the internal display does not work, but the external does, I have had those kinds of situations happen before
