Reset the SMC, as per > How to reset the System Management Controller (SMC) on your Mac - Apple Support


Then set the slider up up a couple of minutes and wait for the display to go to sleep without touching your mouse or keyboard. If it does not sleep or wakes immediately, then you may have a faulty mouse, keyboard or other USB device that is preventing display sleep.
