Unfortunately, the flash mode is not available when in video mode, only in Auto scene modes. As for switching back to Auto mode to test the flash, your battery may have been too low to function. The flash needs an ample amount of battery in order to work, so try recharging your P90's battery. Here is the [[Nikon Coolpix P90 Troubleshooting|troubleshooting page]] for any other problems you may encounter.
