So I recently finished soldering my first 8 Cadet Modules and this would be my first dive into video synthesis. I hooked up the RGB Encoder and a Video OSC to my power bus and connected them both. Unfortunately i did not get any output to my monitor, so i kept trying with other sources like holdin…

The Cadet II has both a B&W output (top RCA jack) and a color output (bottom RCA jack). You can also commonly get only a black and white display if the broadcast standard you selected (NTSC/PAL) does not match your equipment - region map here . You need these to match on the sync generator, color enc…

You only mention hooking up the encoder and vco. you also need the sync generator plugged in, working, and providing sync over the 14pin sync buss. The two rca jacks on the encoder are duplicates, they should both be color.

Error: the bottom diode (D2) is reversed! as for the rest of the soldering, as far as I can tell from the picture. these look dubious: [image] reflow these points and other bad ones, so that they look like this: [image] also: check if your switch is set to PAL (or NTSC if you live in the US) …

Thanks! Think I must have made this incorrect impression from troubleshooting some monochrome output problem when setting up my own Cadet system. In my case I don’t get any signal out when the RGB encoder isn’t connected with the sync bus, just a blue screen or “no signal” as if the display weren’t…

First of all thanks for all the reply and advice guys, really appreciate it. After posting the picture on here I noticed the wrong diode as well. Hopefully I find the time to fix the diode and maybe some other sloppy soldering by Thursday. It shows that this is my my 2nd ever soldered module. For …

I finally had the time to resolder the mentioned parts above and fix the diode direction. I’m getting better results but the color is still missing and it overall looks like it is not working the way its supposed to be. Maybe i can upload a picure in the future. For now I gave my Sync generator, R…

I reflowed some points on the RGB Encoder, and checked everything around the rbg to composite encoder and the crystals. The parts placed seem to be correct and i got something like this: [02] The image quality is kinda crap sorry about that, i was in a rush. Those are not white bars they are rath…

I made this and this video to showcase the output i get from a vco, and the encoder. The VCO is patched into the green input by the way. Im really out of ideas, i checked every part soldered onto the PCB and reflowed some again.

This Problem was solved by swapping out my ATMEGA Chip on my Sync Gen.
I had an empty one as described in this topic.
