Xbox 360 i do not understand how to hook up to hd.

WITH THE TOSHIBA 51H83TOSHIBA TV YOU CANT HOOK UP HD CABLES TO THAT SPECIFIC TV FROM YOUR XBOX 360 BECAUSE THE DEVICE ISNT EQUIPPED WITH THAT CAPABILITY

component leads from xbox to component in on tv

You may need to change your HD settings on the back of the console ( HD setting is actually on cord ) I had that issue when I first went online w/360 . If that does not help u know X box costumer support will repair any damaged system prob. no cost and does'nt take as long as they say.

You have to use the regular red and white cords(not the yellow) and u have to use all 3 hd cords. If ur tv doesnt have a place to put the cords in, then it isnt HD. Also on the plug connecting to the 360, there is a switch that has HD and regular, switch it to HD. hope this helped.

put it on hd. the big plugin that say tv or hvd

Your component cable is probably switched to the HD setting. You have to switch it back in order to get video when hooked up to a regular TV.

Check if you turned on the HD or not.. if your TV isnt HD then it wont show anything but the 360 will turn on still

hey man i understand your problum the reason why your xbox wont show up on both of your tvs is because 1. your tvs are no good or 2.you dont have the right connection to play your xbox on the hd tvs

You can go to Wal-Mart or any major electronics store and buy a splitter/selecter for your different devices.

Basically, the unit will allow you to connect a few input devices (xbox, ps3, whatever) into one HD connection on an HDTV. You will be able to select which device uses the HD connection to the tv through a switch.

I hope you find the item :-) A Competent electronics salesman should be able to help you out just fine!

change the plug on the back of your xbox 360 from hd to tv unless of course your tv is hd then change it to hd :]
