If your screen isn't turning on, there could be a couple of problems that are causing it. Check to restart your computer one more time to make sure it truly is not responding and doesn't have a battery issue. If that doesn't fix the problem, you will need to manually enable or disable your screen to make it responsive again. Take a look at the [[Sony Vaio VPCW21FX Troubleshooting|Sony Vaio VPCW21FX troubleshooting page]] and see if that solves your problem.
