Toshiba 42H82: No picture, sound ok

    I have a 6 year old Toshiba 42H82 RPTV. It served us well with good
    picture quality. However, two days ago, when we turned it on, we saw a
    very bright picture for a few seconds, some sound ("poof")" and then
    the screen went blank.
    We still have sound and the TV reacts to the remote (e.g. mute,
    different channels).
    I unplugged it over night hoping for a (software) reset but this
    wasn't it.
    I understand it's difficult to diagnose this with a simple email
    message but maybe sombody out there can give me a hint. For what it's
    worth, I do have access to a reasonably well equipped electronics shop
    and the 42H82 service manual can be obtained on ebay.

    If I can't fix this myself, is it worth the >$100 to have a TV tech
    come and look at the set (and then pay for the actual repair) give
    that my TV is already 6 years old. By the way, what's the typical MTBF
    of these CRT RPTV's?

    Thanks for your help.

    Need to have a qualified "Poof" inspector to determine what, in addition to
    the service call, it will cost to resurect your Toshiba. May have been a
    failure in the audio, registration, power, or deflection circuits. There are
    probably fuse devices, when checked, may point the qualified technician to
    the correct circuit(s) that need repair.
