I've been using the HDMI connection to play on my XBOX 360 for about 4 months, with no problems at all. I decided to watch some avis from my computer which has Windows 7 and a GeForce GTS 450 video card. It was fine for 4 weeks but then I began to get this little horizontal "black cracked lines" and after a few second of that the screen starts to blink black and back to normal in lapses of 5 seconds.
Now I tried to use my xbox again and in this case the screen goes black, crackling sound, a bit of a green block displaying, then get the image back, and stays playing up like that for a while. In general is like the TV is losing signal. I changed HDMI port and cable and I haven't changed a single setting ever. I know the Okano is not a great Tv either, but I don't understand why it worked before and why I got these problems now.
