  1. I'm thinking that since it goes as far as it does before it shuts down, and
    since the behavior of it resembles certain other repair experiences I've had
    in the dim and distant past, that just *maybe* the reel sensor has something
    to do with what's going on here.

    This is a very strange setup -- the sensor appears to be mounted on the board
    that sits under the transport, and sticks up, getting into the right
    position when it's all put together. A couple of other things only connect
    during assembly, too.

    Anyhow, what am I likely to be looking at with this sensor, assuming some
    sort of optointerrupter, an IR LED on one side and what, a phototransistor
    or photodiode on the other? Any suggestions as to how to test this? Also,
    where the heck might I get one?

    I'm told this unit was made by Funai, anybody know of a good source for

    Go to this site,
    Look at model EV806N. Does your chassis look like this? If so, the mode
    switch is dirty\bad. (If this is the one you were asking about a few days
  3. That gets me to a picture of a Daewoo chassis. Perhaps I've been misinformed?
    There is some resemblance there, yeah.
    Same one, I'm not in any great hurry to deal with this, since I'm looking at
    this unit as a favor to a family member and not doing retail repairs any more
    (and haven't for over a decade).

    Mode switch -- if I remove the connector and one screw and pop out the white
    plastic assembly with the small motor that's shown on the top right of that
    top view picture, that'd be the switch on the underside of that assembly?
    I'll fiddle with it some, see if there's anything I can find out...
