langostinotino,
I'm sorry to hear that you're having this issue.
There are two possible things that you could try:
1. Change the resolution in the game console by connecting it to the different TV that does work to see if it's a resolution issue. 720p would be a safe bet, as would 1080i. At least see if you can get a picture using one of those modes.
2. For the TV, select the HDMI input that you're using with the game console, and go into the menu and edit the name by scrolling down to the INPUT menu. Select Edit Input Name, choose your HDMI input and change the name from "----" to "Game" to see if that helps.
Keep me posted.
