I read the install notes but many sets don't understand big cards.
The .sec file looks to be 15.8MB so any 2GB or smaller card will do fine.
I HAVE A TCP50G15 Panasonic PLasma.
im following the instructions on their website ot update the firmware but the TV DOES NOT respond.
I used a 32G sdcard, formatted it in my mac for fat16 dos
i copied over the single .sec file from panasonic
I turned on tv
installed the card
pressed ok on remote
