I purchased this item Technika 19" HD Ready LCD TV with built-in Freeview, DVD player & iPod Dock 19-218 - Tesco.Direct recently. It doesn't have a red and white cable slot, so i can use the default wiring for HD on my xbox 360. I solved this by purchasing a hdmi cable. However my TV doesn't pick up the xbox 360 through the hdmi cable. It just says "No Signal". I had this issue before and had to change the hd resolution settings on my xbox. However it got a live update and reset them. I am wondering how would i go about getting my tv to register the xbox. There doesn't appear to be a menu so i can change my tv's hd quality to match that of my xbox's and i'm not totally sure what my tv's default is. Thanks alot for reading this. Matt.
