Not all pins have to be connected. There are different standards....
Type U (universal) - provides connections to all 21 pins.
Type V (video) - provides all connections excluding audio pins (3,1,6,2&4).
Type C ( composite video & audio ) - provides all connections excluding
RGB Video & Blanking pins (15,13,11,9,7,5,16&18).
Type A (audio) - provides all connections excluding Video pins
(19,20,17,15,13,11,9,7,5,16&18)

Cables with 1 overall screen only usable @ 50cm MAX length & will suffer some
crosstalk.
as the screen is quite in inductive at 4.3MHz, proper full mesh crossed braided
"S" input 15+20, crosstalk @ 4.43MHz in log cables causes fine patterning!
WARNING
Some VCRs (expensive JVCs) blow internal pcb fuse if the SWITCH tally wire is
shorted to ground! So watch those floating around bare screens inside the SCART
plug!
Why Don't U send an interesting bul?
