HDMI Cable Difficulties

[Intamin]

So I started watching American Psycho fine. Stopped it, came back several hours later, and could only get a green screen. Took out the disc, loading nothing, and still got the green screen. Hooked up my component cables and loaded the disc and everything is fine. Tried putting the hdmi cable in my hd player, and this time got half of a green screen half black screen, but same result, no picture. So, any ideas on whether or not the hdmi input on my tv is bad or if I just have a bad cable. I've only had the cable since I got my blu player, so back in August/first of September. Thoughts? More than likely I'm just gonna buy a new cable, but didn't want to waste the time if I knew it was my input that was indeed bad.
