We have the same problem, same model. Ours was manufactured in Nov 2007, we purchased it Jan of 2008. Hitachi said I needed a firmware upgrade, but it won't stay on long enough to do it. Called back and they said someone needs to come fix it. They did GENEROUSLY offer to pay for the parts. I'm scraping it and NEVER BUYING ANOTHER HITACHI ANYTHING IN MY LIFE.

    Just following up on my progress...

    Well I've never seen a poorer, more incoplete "service" manual in my life..... Anything "serviceable is not included. Whole schemactics and boards are missing. Cross references from board to connectors, etc do not exit. Pretty near a waste of time...Component level voltages are not given, etc etc etc.



    If this is representitive of other manufactures I give up on television....This is a complete Hoax.



    Two years and two thousand dollars??????

I have my Hitachi 42HDT79 42 in. Plasma Television on my wall and I have no voice, just a loud squeeing noice. It doesn't matter what volume its on.


It of course may be a audio problem in the set (main board) but is a box or anything external being used for sound on the set? Same problem with a DVD etc the only thing connected to the set?
