Page 3 of the
TV/VCR, Side Wiring Installation diagram for the 2004 Minnie W324F & W324V shows both the side TV and VCR to have 12V power plugs which plug into a 2-outlet 12V wallplate as shown on page 4.
Page 13 of the
Body, 12 Volt Wiring Diagram for those coaches shows the socket wiring on the right hand side at location C-1 & C-2. Power to those sockets comes from the wire labelled
EX, described in the
Wiring Identification Guide as:
EX / 14 YEL TELEVISION POWER SWITCH TELEVISION WALL PLATE
Tracing this wire back through the diagrams shows it connecting to a 'TV SWITCH' which can be seen on page 3 (location C-5) of the
Body, 12 Volt Wiring Installation diagram for these coaches. Detail
CK on the next page shows the switch.
I suspect that you need to turn on that switch.
