To all that have xbox 360...

Why wont my xbox 360 let me set it to hd even though its on a hdtv?
Ok so i have had my xbox set up to a hd tv and it played on hd absolutely fine but my brother took the wires out and now wen i set it to hdtv on the av cable my tv says "no signal"? Wtf it only lets me see the dashboard if i set it to tv, and now i have to play in garbage quality. What the hell?

I think there's a little switch that you have to flip to change between standard and HD.

I have it circled here:

Yeah, i know but thats the problem. When i switch it to that the tv says no signle... it has always worked before my bro pulled out the wires. Hope he didnt break them. I wanna play Modern Warfare 2 in HQ daminit lol

are the green, blue, and red tipped connectors plugged in? or are the standard red, yellow, and white connectors plugged in?

also, I switched everything over to the HDMI cable...much much better and easier than dealing with all those cables.

You do have a HD TV right? What kind?

you might need a new cable

get the HDMI Cable and ur problem will be solved.... If you are going to have to buy a new cable anyways, u might as well

yeah everything is plugged in.....the prob is i dont have a hdmi 360... but what ill do is ill borrow my freinds 360 cables tomorow and see if thats the problem.

he prob is i dont have a hdmi 360 so i cant still use hdmi cables rite? there is no type of adaptor to my knowlge at lest, please someone correct me :D

What kind of TV do you have?

i either use it on a samsung or a dynex, both HD
