It sounds you are seeing your iPad screen dim just before it would go to sleep, and then it goes bright again so it will not go to sleep. I would start by quitting all the running apps on the iPad:
1. Press the Home button two times quickly. You'll see small previews of your recently used apps.
2. Swipe left to find the app you want to close.
3. Swipe up on the app's preview to close it.
When you have done that restart the device and test the issue again:iOS: Turning off and on (restarting) and resetting
Although I don't think it will come to this, if the issue persists, backup your device to iTunes, then restore it as new and verify that it works.
How to erase your iOS device and then set it up as a new device or restore it from backups
If it does, then restore your backup to either verify it still works and the software just needed reinstalled, or isolate the issue to the backup file itself.
