Panasonic has discontinued their only available HDMI interface card for Series 8 & 9 industrial plasma monitors. I have 5 monitors and never needed HDMI until the spiffy little LaCie LaCinema Rugged HD came out (will post separately).
Even though Panasonic still lists the TY-FB8HM HDMI Adapter on their website and on their parts website, I have confirmed that it is discontinued. No thanks to Panasonic on this. They wasted almost half a day of my time. Also, the "Panasonic Plasma Concierge" service is nothing but an outsourced call center of non-professionals trained only to read the Panasonic website to technically illiterate consumers.
Note that Series 10 HDMI adapters do not work on prior models. So owners of Panasonic Industrial Plasma Series 8 & 9 are out of luck if HDMI inputs are required.
