I have tried every single advice listed above and mine still doesn't work. I was playing Oblivion and went into the main city when it froze. I truned it off and tried turning it back on. Now all I get is a "no signal" on my tv no matter if it's through the AV connection or the HDMI. Makes not difference. I am so frustrated I don't know what to do!!!! I mean my tv won't even recogize that any devices are plugged in. My options are just tv and the direct tv p[top. Can ANYONE help me???????
