    Hello,

    I recently acquired a Zenith projection TV. I have repaired all
    original problems (i.e. broken circuit board, broken traces) and the
    set seems to be fine except that the blue does not line up with the
    other colors. Before I pay to have someone do this for me, does
    anyone know how I can reset the blue and/or if there are default
    settings I can use? I have accessed the service menu and green and
    red are adjusted correctly, but blue is offset and a bit warped.

    Thanks!

    P.S. I don't get into this group often so please email me at
    if possible.

    The Tv has a fault call in a service shop
    and have the fault diagnosed before you
    have more problems.

    It sounds like he has some service ability, what circuit board was broken?
    If it was the convergence board then maybe you missed a trace somewhere or
    made a solder bridge. Also does this set use the big STK convergence IC's or
    discreet transistors?

    I am a computer technician, but I don't have specific experience with
    projection TVs. The previous owner cracked the front panel circuit
    board. I was able to re-solder the connections and get the controls
    and remote functions working again.

    I'm preparing to take it into a shop for an estimate, but thought I'd
    ask around for a less expensive solution first.

    Thanks!
