After 3 years of frustration and having to use component in 1080i rather than HDMI because of the black screen / no signal issue, I finally solved the problem. The no signal was caused by a HDMI handshaking error- no hardware fault. after reading some posts on another site, I decided to buy an HDMI switch : http://www.monoprice.com/products/product_print.asp?c_id=101&cp_id=10110&cs_id=1011002&p_id=5081 I had very little hope that it would work, as I had tried everything other than this (different cables, different TV's, different firmware, different methods of resetting and configuring options). but I am happy to report , it works perfectly. I am able to game in 3d now on my ps3, (which component didn't allow). apparently it strips the handshaking error off the signal or something like that. good luck edit: to people posting that it was a simple matter of resetting the ps3, this thread is for people who have already tried everything, and no matter what, HDMI won't work on their PS3. There is a handshaking problem with the ps3, google : hdmi no signal ps3 and see how many hits you get. as I mentioned above (different cables, different TV's, different firmware, different methods of resetting and configuring options, and settings on both the TV and ps3 did not work) read more here : http://www.thebuzzmedia.com/ps3-hdmi-black-screen/ quote: "If that doesn’t work, the problem might be your PS3 and TV not being able to establish a secure HDMI handshake which is required for an HD signal. You can try working around this (if your PS3 and TV hate each other) by purchasing what is called an “HDMI switch”, it’s basically a hub but for HDMI connections (as opposed to USB or network connections). You can get a $10 manual switch here, or a nicer remote-controlled HDMI switch here for $25. If you just have the 1 PS3 HDMI connection and don’t need any other connections, just grab the $10 one since it will always stay on the same setting."
