Q: Blank screen issue
iPhone 4 running iOS7 with a blank screen. Unresponsive to home key, lock key, double tap home to clear cache of a frozen app, holding down the lock button for powering off, and possibly the soft reset of holding home and lock together (will be retrying shortly). Only sign of life is when the phone is plugged in to charge, the plug-in sound is produced. Otherwise a black/blank screen.
Anything else I can try?
iPhone 4, iOS 7, unsure of specific version of iOS7

Plug it in again to charge but leave it plugged in for at least 15 minutes. Then reset the phone. Press and hold both the Home button and the Sleep/Wake button continuously until the Apple logo appears. Then release the button and let the device restart. You will not lose data doing this. It's like a computer reboot. If the phone starts up, let it continue to charge until the battery is at 100%. If the phone still does not charge have an Apple technician examine the phone. Make an appointment at an Apple Store to have a technician examine your device. Or contact Apple Support.
