All,

i've here a Mitsumi MDF8-UE3681 RF modulator that with some help from
http://ask.metafilter.com/56826/ now connects an old DVD player to an
even older TV set.

But the picture is negative.


If you over modulate the video modulator, or overload the receiver you
will have inverted and distorted video.



The modulator has 4 pins, 3 potmeters, a switch, coax in/out, and a
cinch connector at the right.

The pins are marked: BS, V, A and B.

A and V is connected to Audio and Video signal.
BS connects to +5v
The a/v shielding and chassis go to GND.

(1 potmeter controls the channel, 1 ferrite core does something with
audio, and the last is a dragging one that does some w/the video. The
switch seems to be for a testpattern with two vertical bars?)
