This happened to me when I attempted to install a software upgrade onto my 7520 unsuccessfully. The red light blinked constantly but the device did not turn on.
The solution for me was to connect the device to my computer and reinstall the operating system using the blackberry pc software (the same software used to backup/restore and install new apps onto your BB.) Even though my device didn't respond to human interaction, it did communicate with the computer. The computer's software detected that the device needed to have the OS reloaded and took care of that for me.
