Support Nexus won't boot, no recovery mode, screen flashes once

http://androidforums.com – Today, I wanted to install the facebook app on my stock Nexus 7 which I bought just 4 days ago. After charging the tablet, I removed it from the power source, started Chrome and went to facebook, when suddenly the screen went static before dying. Now, when I hold the power button, after a couple of seconds there's one white flash on the screen, and that's it. No Google logo, nothing. Naturally, I tried booting in recovery mode via holding down the volume keys along with the power button for about 90 seconds several times in any combination, but to no avail. There's no recognition from And (General)
