Is your machine still under warranty or Apple care? If it is, you might want to make an appointment to let an Apple genius look at. It sounds like your logic board is acting up. If you've done a PRAM/NVRAM reset and a SMC reset, and sleep mode still won't turn off the backlight, the problem is most likely hardware related.

Regards.
