Hey. I installed a rgb Mod V2 from videogameperfektion in my SECAM collecovision. The install was easy but the colors not correct. I Check all the Connections and all ok. The Cable i use is from my PCE, and there it worked Great. What can i do?
It looks like you’re missing a colour. We will need some pictures of your install to determine if this is a fault with the PCB itself or the installation.
I check with a Multimeter. From PCB to DIN PORT. R has contact with PIN 7, G has contact with PIN 3 and B has contact with PIN 1.
Hi There
I would try reflowing the 3 signal inputs using some liquid flux.
I also notice that you are using a megadrive cable. These cables have inline components and its recomended you remove the three resistors on the tmsrgb board and jumper them instead. If your cable also has a csync inline resistor you will need to connect to the other csync pad on the tmsrgb.
If you have carried out the above and confirmed continuity on the RGB lines from the tmsrgb output pads to the scart plug pins then its possible the tmsrgb board is not functioning correctly
Hey. Same result 😩. I remove the resistor on the PCB, and use TTL. I also resolder all the Pins and Check the connections.

I find out, if i press Reset many times the colors often changes. And sometimes the are correct. What Could it be?

Turns out this was a faulty board and a new board was sent to the customer.
