Two n00b Questions

[PyGuy]

I have a couple of Dreamcast/PSone Screen questions, as the title says...

I tested the hacked PSone screen with a PS3 with the AV plug that plugs into all Playstation systems. It works fine but why the heck am I getting a kindof green tint with the display?

I am also puzzled about the idea of how to get a display for the Dreamcast...What exactly do you connect to where on the AV OUT pins from the Dreamcast to the PSone screen? I keep seeing pictures of a fully-working portable DC but I only see one wire connected to the Dreamcast's AV OUT.

Answers will make this project a lot more understandable for a n00b like me.

Solder a wire from the composite out on the DC to the composite in on the PSone screen, then make sure the grounds of each device are connected. As for the green, sounds like something from RGB to me. Try hooking up with the composite and hope it goes away. If not I can't help you.

The green happens with the playstation 3 only, others have had problems with that too.

As for A/V, you need pins 1 (ground) 2 and 3 (Left and right audio) and pin 13 for composite video. Below is the A/V connector pinout.

Pin Description
1 Ground
2 Right Audio
3 Left Audio
4 +12 VDC
5 +5 VDC
6 31kHz (VGA) select (active low) (Connected to PORT9 on CPU)
7 RGB select (active low) (Connected to PORT8 on CPU)
8 Vertical Sync (for VGA)
9 Horizontal Sync (for VGA)
10 Composite Sync
11 S-video Chrominance (C)
12 S-video Luminance (Y)
13 Composite Video
14 Blue 1)
15 Green 1)
16 Red 1)

hey quicc question, do you need to have the ground from the C-Video/ C-Audio connected to the ground of the power supply to get video and audio? or can you leave the ground un connected and still get input?

I only had to connect one of the grounds... From pin 1 on the Dreamcast AV out, to pin 8 or pin 4 on the PSone Screen. Hope that helps!
