    Hi everyone,

    Just wondering if anyone has ever seen this: I bought a Hitachi
    42EDT41 2 years ago (
    42edt41.shtml), and for a couple of weeks now, when I start it up, I
    can see a bunch of green pixels grossly following the image at it
    changes. As the TV gets hotter, they start to disappear and then
    eventually, there are only 1 or 2 that are noticeable after 15-20
    minutes. They are not burned, as they regain their color when the
    image changes. (Also, as days go by, there are more and more green
    pixels at start up).

    This is very, very annoying. So basically, my question is this: before
    they charge me 125$ for an estimation on the repairs, has anyone had
    this problem and if so, how much did it cost them to get it fixed ?

    thanks a lot.

    The fault may be in the matrix decoder, or in the video address
    processor areas. In many of the plasma sets, some of these areas are
    built as part of the main display.

    Your TV is serviced by module replacement, and then doing the set-
    ups. Don't be surprised of the repair is very expensive.

    What kind of "set-ups" do you have to do on a digitally addressable
    display after a module replacement? It's not like you have to
    adjust the deflection and correct for pincushion.

    Ah, that'll be where I went wrong then :)
