No picture after Apple logo

I did Jailbreak my Apple TV 2 succesfully but when I connect it to my TV I can see the Apple logo at bootup but after that the picture disappears/signal is lost. I used Seas0nPass Version 0.7.6 (73) for Mac OS X for the Jailbreak. Any ideas?


EDIT: Got it working after doing the Jailbreak again.

I have had the same issue when I changed the password on my wireless access point. This happened on 2 jailbroken ATV2 in my house. I can reproduce it every time. Jailbreak, get it online, install firecore and then change the wireless password on my router and then I reboot my ATV and nothing past the apple logo. Is this similar to what happened to you by any chance?
