OK here is my problem. I used to be able to play my ps3 slim and watch bluray over hdmi on my Sony 30hs420. I moved my ps3 to my bedroom and plugged it on component to my sdtv. It stayed there about 3 month and when I plugged it back to my living room hdtv, the only thing I could see is a black picture that seems to react to the ps3 powering on and off. And yes I've reset the ps3 video settings. I've tried another hdmi cable; it didn't work. My laptop display on hdmi( I guess it's not HDCP). I've tried my brother blu-ray, I can see the welcome screen and then nothing. Some channels will show on my ATSC tuner box when plugged in hdmi and other won't. Could anyone please help me? I don't really want to buy a new TV and I have a 2 week vacation and nothing to do.
