Hi I am new to electronics and to this forum. I need some help with a electronics if someone can assist me.
I am working on an external LCD monitor for a Video Camera. And I would like to use the signal from the Composite Video cable to power the LCD itself. Is there a way to use the 0.03V (30mV) to act as switch for the LCD monitor? I.e. When the video camera is switched on the LCD monitor is switched on as well. Also, as I am using the video signal to control the power will this interrupt the video signal itself to the LCD?
I noted that the voltage from the video signal fluctuates from 0.02V ~ 1V. But when I switched off the camera as expected there is 0V. I have not knowledge on electronics whatsoever but I if given a circuit and parts I know how to source them and solder them
Below is the simple layout.
