I have a ps3 that I'm trying to connect with my Philips 4606 37". I am using a HDMI cable to connect it, but it says "no signal". The ps3 works on other monitors and tv's, but not on this one. My xbox works, with the same resolution, so I find this kind of weird. I've tried to update with the latest firmware, etc. but nothing seems to work. Any ideas on what is wrong?
