But then I selected 1080p just to see if it looked better. Bad move! It turns out my TV doesn't support 1080p and now the GT1 is kaput. It boots up, displays the Sony name and the Google TV logo, then goes to black. No picture, no sound, no menus, nothing. I have tried CTRL-ALT-DEL which boots the unit, and it displays the two logos then nothing. I think it is "stuck" in 1080p. Is there any way to give it a "first birthday" and get it back to factory settings?
If you are adventurous enough to try to get to the recovery menu, there is an option to go back to factory data reset as first option in recovery menu.
Here's the step by step posted from xda-developers forum by Apeman42 on how to get to recovery menu.
1.Have everything plugged into the unit except the power coord. Have the power coord in your hand.
2.Press and hold the power button and plug the unit in.
3.Continue to hold down the power button for 3 seconds after plugging it in, then release the power button.
4.Wait a couple of seconds and it will say Sony, then you will see the recovery screen.
5.After it loads, press and hold the connect button on the unit. Then follow the directions at the bottom of the screen (Press and hold ALT+ENTER) for 8 seconds/until the bottom message changes. It will change back to it saying that you have to press the CONNECT button, but your remote IS connected.
6.You can now press the numbers assigned to the commands!
You can also go to youtube and search for video id L21guovXDsc to see a video instruction on getting to the recovery menu. I wanted to post the links but I couldn't since this is my first post.
Good luck, I hope this works for you.
