Hello, everyone.
I have a cnc machine which have RGsB ( RGB sync on Green) output which is used as input for monitor screen.
I want to change currently used monitor with LCD monitor which have VGA connector as input.
Do you know how to build circuit which will convert RGsB output to VGA signal which I will use as input in LCD monitor?
We need to know more about your dead monitor. CGA, EGA, VGA?
Look at old LDC TVs. Many have RGB inputs and most likely will work. Many GVA monitors will not.
That will give you sync, but not necessarily the right scan timing for VGA.
Or just buy a suitable LCD panel controller that includes analog RGB input - eg.

Edit - ps. If it's something like a Siemens 840C using BNC video outputs for RGB, look on the CPU board - there is likely a standard VGA socket as well..
Example: **broken link removed**
This is pictures of output connectors from machine (Connectors_on_machine.jpg), connectors which are connecting to monitor (bnc_connectors_for_monitor.jpg ) and input connector on monitor (Input_on_screen.jpg)
The video can have sort of a 'D' connector, but it had 3 seperate plugs.
It has a vero board with a Lm1881 on it feeding a Lcd monitor, doesnt work that well.
We are trying to find what type of video you have. You can not tell us what the old monitor was. You can not make measurements on the video you have. This makes it hard. The picture does not have (PAL, SECAM, NTSC) formats. Each format has different timings. The speed of the video is different. That is why I suggested in post #2, getting a older LCD TV because many of those will work with many formats.
