I’m assuming that you removed the battery from the laptop before dis-assembling it to remove the HDD ;-)
With the laptop turned on try shining a torch at an angle close to the screen to check if you can detect an image at all.
If you don't see an image then you may have to check your work to make sure that the LVDS cable is still connected OK on the motherboard as you may have disturbed it when removing the keyboard or the palmrest assembly when accessing the HDD.

If you do see an image it still might be a loose LVDS cable as I think that the backlight power is also fed through the same cable or if if it is OK and you didn’t remove the battery you may have caused a problem with the backlight power supply on the motherboard by accidentally touching something that you shouldn’t have.
