HDMI Problem? - Lg LC7D

[Confuzzeled23]

Hey Everyone,

Today I went out and finally bought an xbox elite. The only thing I am wondering is that. I am using HDMI on my new HDTV and when I first turn on the 360, my tv screen still shows no single, then flashes invalid format really fast, then finally shows up just intime when the 360 logo is fully shown and about to go into the dashboard... Is this normal for HDMI, I am new to all this stuff. Also, when I put a movie in, the screen on my tv went totally black... I could hear the movie but not see anything, I could hear the beep when I clicked the dashboard button, but nothing showed on the screen. So, I removed the movie.... still a black screen. Then put the movie back in, and the movie started playing normally and everything was back to normal. Is there a certain setting I should set it to, or that it has to be on. I currently put it to 1080i because I thought it was best, could this be to high for my tv or something? What could I do to fix this, or does anyone have any idea why it would do this? Has this happened to anyone else?

Thanks for any answers

It's probably a connection issue - unplug and replug the HDMI cable a few times to ensure a good electrical/mechanical connection. Also make sure that the settings in the 360 are properly set - 1080i should be fine for all TVs. Make sure you power on the TV first to ensure a good "handshake" between the TV and the sending device.
