My HDMI cable broke and I thought the end bit was stuck in the xbox so I fiddled around in the port and realised it wasn't and it was just part of the xbox, so I went to Currys and bought a HDMI cable for £4.99. I get back home and try it out and it says 'Searching for signal' and nothing else in the middle of the screen, I've tried everything, switched the cable around, re-set the xbox and telly but nothing works, what is wrong with this?!! When I take the cable out it says no signal and when it's in it says searching so god knows, please help.
