Seas0npass installs but?

I have a 2nd gen with software at 5.0(4099). After finally getting it to jailbreak using the current version of seas0npass i plugged it in the my tv and the green light continuously flashes and the screen has the blue itunes logo with a power cord picture under it and will not boot into apple tv. Any help will be greatly appreciated.

Thanks, Bobby
