System Fairchild composite video modification
Working mod schematic
Fairchild Video Entertainment System / Channel F
Channel F II
Available 5V shown with red and blue wires in top right position of circuitboard and composite signal source has been hooked up with a red clamp on a resistor by the LED.
Audio hookup point is the transistor pin that the green arrow is pointing at. Last circled jumper should be opened to remove annoying moving patterns over colored areas.

In this example 5V and ground is hooked up directly to the 5V regulator, video is taken from capacitor pin (yellow wire).
The white wire from the speaker is originally connected to the little RF board, connect it to the PCB instead.
In the image you see audio hooked up with a loose resistor and capacitor instead of using the PCB.
