RGB Mod Samsung SMP-150

Post by madman_lxl »

Hi Everyone,

So I'm looking at modding my old PVM which is an old Samsung SMP-150 for RGB Input.
I've read up and am trying to wrap the old head around what i need to do it inject an RGB Signal.
So far I have the service manual and the jungle chips datasheet. Links below.

So from what I'm understanding I need to connect up pins 23(Red), 24(Green), 25(Blue) with a 300ohm resistor on each line.
Then to pull pin 26 (Blanking) high with 5v. I can cut the trace going to the micom so i can either have the OSD or the RGB Signal from my inputted device.

If that is at all correct (i'm sure it's wrong) how do i get the c-sync inputted? does it just go inline to the first input on the system?

Any help would be great. :) Thanks.
