Model number?
Our "old" ITT set has a 5 pin din (on the front) but it is only for headphones. Geo
Thanks you all for the responses.
Its is an ITT ideal Color 3725, chassis is compact 80 DST as far as I
know, mid 1980s vintage. On the front it has a 1/4" jack socket for
head phones and a 5 pin DIN for audio output. The aerial and AV are at
rear.
After various experiments inside the set, I have found that the AV
socket here really does not seem like the Grundig /standard pinout I
found earlier.
Pins 2 and 6 are wired together on the pcb and shorting pins 1 and 5
did not bring about AV switching.
......No wonder everyone now uses SCART!
Now...using a commercially-available adaptor 6 pin DIN plug to 4 phono
sockets
I discovered that the centre pin of the red phono socket, when shorted
to centre pin of the white phono socket, passed the 12v and switched
the set to AV.
The other two phonos (yell.+ black) were audio in and video in. The
set worked fine with this setup.
So now all I'll have to do is trace the signals back from the phonos
to the pcb in the set with a multimenter to determine the exact
pinout.
Since it is a nice big size (28") in good condition , I'd like to see
it being put to use with a DVD instead of being dumped. Round here,
people are leaving working sets out for the refuse collection if they
have no AV inputs these days.
