Pulling my hair out trying to figure this out. I had my PS3, Blu Ray (LG), and cable box (Samsung/Cablevision) all running to my TV (LG) and everything was working great. I had the TV wall mounted last week and the HDMI cables for all run in the wall. The cable box and the PS3 work beautifully, no matter what port I hook them up to. The Blu Ray though gives me a "no signal" message on 99% of my hook up attempts. The other 1% is does me the home screen but there is a tremendous amount of picture noise. I grabbed my Sony Blu Ray from another room and it works ago, but there is a decent amount of noise/random "snow" on that too, both regardless of what port I use.
I'm assuming that it's not the wiring since the PS3 and cable box work ok, but can't figure out wht else it could be. The only other thing I could find by searching was a potential HDMI handshake issue, but I'm not sure how to fix this. Anyone encounter this/know what to do?
I am using slim redmere HDMI that are going from the TV to HDMI wall plates, connected via in wall rated HDMI to lower wall plates and from there to the components (all from monoprice). Like I said though, other components seem to work ok on all ports, and I also traded different cables.
