My wife synced her iPhone 3G and installed two new apps yesterday. While my son was playing with one of the new apps in her company (ie no dropping or water) the phone went blackscreen. Son says the rotating gear icon etc did not appear. The app was a Disney game.
The phone does respond to 60 seconds of pressing of the home and on buttons together (ie hard shut down/restart) and attaching it to various Apple brand charges and computers never produces the Battery Charging screen.
Is there anything to be done short of locating a repair shop?

You could attempt to put the iPhone in DFU Mode, and see if you can restore from iTunes. But this is almost certainly a hardware problem, and will require a trip to an Apple Store or a service provider.
To try DFU mode (note that this does a complete wipe, you'll have to rely on whatever backups you made previously):
If this is successful, you should get an iTunes popup stating that it has detected an iPhone in recovery mode. You can then follow the iTunes instructions to restore the software.
