PSOne LCD Pinout

The luma isn't composite. The screen uses the psone's luma as sync. If you tried composite on the 3rd connection of the 1st connector it wouldn't work but c sync works there. I got my composite off the 2nd slot 1 connection. It is used for like connecting a camcorder or anything else composite. Here is where I wired my composite, left and right audio.

yellow-video, red-right, white-left.

You can also connect the 3 other pads together unless your going to use a headphones jack wired correctly to it. the hp_r hp_s hp_L just short them together.

oh, so you're actually using the mini-jack input for video and audio?

yes, but I'm not using the jack but wires that were conected to it on the lcd controller pcb. There is no other composite connection.

This is how you would hook up a console with rgb to the screen.

You should check at www.gamesx.com first to see if you need to do anything to the console to get rgb.

If you arn't going to use rgb just hook it up like this.

Yellow-Composite Video
Red-Right Audio
White-Left Audio
Make sure you connect the consoles ground to the screen too.

Thanks a lot. Also, on the playstation to get RGB video would you connect the video to the c sync (I THINK sync is in the ntsc pin).

So far Mr. Mod looks right. I check the lines myself and verified slot 1 #s 1-6 and slot 2 #s 9 and 10 which is all i need

Has anyone tried removing the 7805 chips in there? I'm wondering if it would be better to use a DC-DC converter instead...

I would use the s video y as the sync cause that's what the screen normaly uses. Check http://www.gamesx.com/avpinouts/psxav.htm

On gamesx.com, they said i need a 220uf capacitor in each of the RGB lines to get an acceptable picture. Is this true for the psone lcd, because i only think its true for him because he uses computer monitors. Has anyone connected a psone to the psone lcd using RGB and get it to work successfully. It's also saying that i need a LM1881 or similar circuit to strip the sync from the video line. Do i really need all this stuff? Thanks.

You don't need the caps since the psone works with the lcd w/o caps. Use the s video y line as sync and you won't need to make the circuit. Use the psones svideo y out as sync. Remember that the sync in on the lcd is port 1 pin 3.

Could somebody answer my question about the 7805 chips? I think it would greatly reduce the power consumption if these were replaced by a direct 5v line running to the system in both places...has anyone tried this?

I got RGB to work on the screen.

I had to use a capacitor on the sync line to get a stable picture. You may or may not need one.
