Video Camera Viewfinder Screen: How do I Identify Everything and Get it to work? Answered

I recently found a very old video camera and thought I'd take it apart. Inside I found a lot of stuff I can use in other projects, but the thing that interests me the most is the viewfinder. I did some searching around and found out that some people had been able to hack them for use with devices other than the video camera. 

My only problem now is that I have not been doing this sort of thing for long and do not know how to go about doing this. How should I go about it? All I know is that there are 4 wires that went from the viewfinder to the main body of the camera: red, black, orange, white.

Red and Black is probably power, 5V, 6V, 8V,10V OR 12VDC ?
White is probably the video. Orange could be source for generating the
high voltage needed or could be the raster or sync to save on block diagram
components normally filling a std monitor.
A lot more can be gleaned, if you have the unit it came from.


I do have the unit it came from. Should I post some pictures of the board this was attached or is there something in particular I can look for? I tried red and black for power, with 8V, 9V and 12V to no avail. I'll try a lower voltage later, but I would think it would show some signs of working at a higher voltage than needed. If it still does not work how would I go about wiring the orange wire?

More you post more I might be able to help, your first pic is excellent detail.
A scanned image of the PC side of the monitor would also be good to see.
If there is a refer name / number on the monitor enclosure??
Depending on the manufacturer colors could be reversed.
Do you know the battery voltage the camera unit used.
one of the wires could be some sort of feedback.

Think carefully before applying power as wrong way wrong level
can perm damage the delicate electronics.


Is there a way I can tell if this thing is broken? The video camera itself did not work so I was wondering if there was something I could do to see if the monitor even works.

Powering it was the only way I can think of.


I plugged in everything again and powered up the camera and it started to smoke. I guess it is time to move on.

Yea.... sounds terminal.
Sorry couldn't help you more.


Thanks for all of your help up to this point. If I ever get my hands on another camera to be used for parts, I'll know what to do and what not to do.

The video camera uses 9.6V 1.1A
The monitor case uses 8V 0.61W and says "JVC MOD, NO.YU30315B".
I drew on the corrosponding wire colors since the image came out a little blurry.

Thanks for all your assistance so far.
