Have you had any updates regarding this?
My father has a 50" LG 1080 HD Plasma television that he purchased sometime in 2010. He first purchased a Panasonic blu-ray player. When using the HDMI cable to connect the blu-ray player to the television, the television would display a blank screen. So he returned the Panasonic player and purchased a Sony player.
Guess what, the same thing happens! However, when initially turning the Sony blu-ray player on, a brief "Sony" welcome screen appears on the screen, but disappears almost instantly.
I investigated further, and a picture displays just fine using the HDMI cable on my Samsung LCD television. I am currently utilizing the Sony player with my own television to put it to good use.
However, he has a DirecTV HD satellite box hooked to his LG television with an HDMI cable, and it works flawlessly. So the TV does not apparently have a fault with the HDMI inputs. I contact LG, Panasonic, and Sony to ask them about this issue - and EACH and every single manufacturer told me that their product was defective. Not apparently so!
I want to find him a blu-ray player that works, so that he can receive Netflix on his television set - but I am afraid that I will buy another unit that will not be compatible with his television set.
PS, I apologize for resurrecting such an old thread - but I searched and this was pretty close to the same problem that I am trying to find a solution for!
