Playstation PS1 - RGB - Sync on Luma

[Gui-1981]

Hi everybody!

I'm trying to run my PS1 on RGB mode without success.

My configuration is:

PS1 ---> commom wiring ---> sync stripper LM1881 ---> GBS8200 ---> LCD Monitor

The schematic is:

PS1 PIN 12 ---> Electrolitic Capacitor 220uF 16V ---> GBS8200 CONNECTOR P11 PIN G
PS1 PIN 11 ---> Electrolitic Capacitor 220uF 16V ---> GBS8200 CONNECTOR P11 PIN R
PS1 PIN 9 ---> Electrolitic Capacitor 220uF 16V ---> GBS8200 CONNECTOR P11 PIN B
PS1 PIN 8 ---> LM1881 PIN 4 ---> GBS8200 CONNECTOR P11 PIN GND
PS1 PIN 5 ---> Ceramic 100nF ---> LM1881 PIN 2

LM1881 ---> PIN 1 ---> GBS8200 CONNECTOR P11 PIN S

LM1881 ---> PIN 3 ---> NOT CONNECTED
LM1881 ---> PIN 5 ---> NOT CONNECTED
LM1881 ---> PIN 6 ---> 680K AND 100nF PARALEL
680K AND 100nF ---> LM1881 PIN 4
LM1881 ---> PIN 7 ---> NOT CONNECTED
LM1881 ---> PIN 8 ---> +5V

My sync stripper is similar to the LM1881 DATASHEET.

Well, after do all of this I did tests....

When I run using RGBS of my GBS8200 the screen don't stay sync.
So I tried run using RGBHV and the screen stay purple. I disconnect the Red and Blue wires and the screen stay black and White....no green....just luminance.

So I did the same test in another console...

I had a better result in RGBS, but in RGBHV was the same result.

Finally, I have two questions:

1) How to SYNC the screen using RGBS?

2) Where is the Green using RGBHV?

This will end up getting moved to the Hardware forum, so you know...

Yeah, lemme do that and give it a quick bump.
