    I have a toshiba 55hx70 rear projection tv. Lately there have been
    blue lines across the top half of the screen.
    I called my local toshiba service center and he wanted $99 to come to
    my house and would not apply that to the cost of repair.

    The convergence controls in the owner's manual do not address this
    problem.
    The set is 3 years old and out of warranty.
    Is there anything I can do to attempt to correct this problem.

    Thanks for any help.

    The set needs properly diagnosed and repaired by a qualified technician. It
    does cost money to pay a good tech to sit on his behind while he drives
    around, plus the added costs of the truck and portable equipment. Well $99
    is not an outrageous amount for an in home service call.

  3. This is not an adjustment. There are most likely some failed caps,
    and maybe the drive IC's for the convergence. You are best off to
    have it properly serviced. You may not have success to do this
    yourself, unless you are properly trained, have the service manauls,
    and tools.

    If you don't know what you are doing, you may end up changing a lot of
    parts that were not necessary to change, do more damage, and there may
    be some safety issues with this as well.

    I am a retired TV tech and have one of these decorating my living room,
    too. It is working great which is a good thing because I have been
    unable to locate service lit for it.

    Can anyone point me in the right direction?

    You should contact the Toshiba parts department, or their authorized parts
    rep directly. The manual for your set should be about $40 to $60 US.

    Thank you but that is one of the dead ends I have been reaching.

    Good Luck,
