For simple wiring, please refer to the introduction in the picture. The monitor only supports video input without audio amplifier. It can be replaced by a small computer speaker or other power amplifier.
Those with strong hands-on ability can solve the audio playback problem as long as they find the audio input terminal, and a complete nostalgic black and white small TV will be done.
After connecting 2 wires of 12V power supply and 2 wires of video signal, you can watch the video by pressing the power switch button, but it will automatically shut down after only half a minute of display, and you need to press the switch again to start. We tested the small button next to it and it can be displayed all the time without letting go, so you need to press the small button and stick it with glue to prevent it from bouncing.
There is a brightness and contrast potentiometer, and the wiring is very simple. Just connect the 4 wires on the picture tube to play the video image. The red wire is connected to the positive pole of the DC 12V power supply, any black wire is connected to the negative pole of the power supply, the yellow (some are red wires) is connected to the video signal input, and any black wire is connected to the signal ground.
