I am trying to upgrade firmware on a hitachi
I had an issue (OTA no audio in channel 2-1 and 11-1) on my Hitachi 42HDS69 so I tried to upgrade the firmware. The manual as well as the instructions on TV all state to use a MMC card. Someone on an internet forum also stated that a 7-pin MMC is needed. I tried exactly that but it did not work. Finally I tried a 128MB SD card and it worked like a charm. The firmware upgrade fixed my OTA audio issue. I went from V0108 to V0125.
All you need to do is to extract out the .F02 file and place it in the root directory of the SD card.
BTW, I did call Hitachi customer support. They refused to help due to the TV is too old (about 10 years old).
I guess it all depends on who you speak to at Hitachi?!
