PSOne LCD Pinout

Post by **gannon** » Fri Aug 27, 2004 3:57 pm

I guess it would be a good idea to sticky this thread afterall. Below is the psone screen's controller card pinout. It's pretty much self explanatory.

Nice job. I was going to do this sometime so I could hook it up to a super gun but you beat me to it.

Yeah, but I'm missing the most important input, and that's Composite/C Sync In. I tried to find it, but it didn't seem to be hooked up to any of the cables

gamesx has basically the same thing.

where? I didn't know they had the psone lcd's controller card pinout

Oh yeah, and I hope you're not just talking about the ps a/v jack pinout

Have you checked this site http://starfox.ucc.asn.au/carcomp/serio_lcd.htm It shows you how to connect it to vga but it's for pal so I'm not sure if it would work with a ntsc screen. Gamesx says that the c sync is the ntsc video pin. Here's where someone connected sync http://www.arcadecollecting.com/info/sonylcd.jpg

That's all i could find about the screen w/o desoldering the connectors off the board that connects to the psone.

yeah, c sync and composite are the same lines, I'll check those sights too.

I just saw the second site you listed, and they wired directly to the header board, this pinout is for wiring to the lcd controller itself

yeah, but couldn't you trace the lines to the lcd?

That's what I've done, but I can't see where composite/c sync is on the wires,
Also, I forgot to label the power input. V in is wire 1 and Ground is wire 2 on the first slot.

I desoldered all the connectors with a heat gun here are the scans. I would finish your diagram but I need to sleep

Thanks, those scans might help somebody, but if you look at the composite input lines on both ps a/v ports, they seem to be connected together, but not to the screen.

Here's what I made

I traced all of the lines and this is what I came up with. The thing is that I can't get my lcd to turn on fully. It starts up and flashes the image for a sec but then goes to a blank screen. The 12th pin needs 5v so the screen stays on but whatever I do i can't seem to get mine to stay on.

Maby I fried it. It would be nice if i had another header board that worked so I could test my lcd.

The composite video works even though it is supposed to be Y in, I see a clear picture for a second so it works but my screen switches to the "sleepmode" mayby there's somthing I missed on the header. Gannon if you could try it that would be great but I don't know if you have a working lcd.

It's weird that we got different results for the pinout. I'll try those connections since I just got a new lcd, I just don't want to break it.

Edit:
Nevermind!! I just realised that I had the wires for ports 1 and 2 reversed

I'll try your diagram mr.mod.

Yeah, I forgot to tell you that.

There must be somthing I missed on the header. I'll buy a new screen soon so I can test it with the header and see if my old screen still works.

The odder thing that I noticed is that you got Yin labelled as Composite in. It would be pretty odd if it actually is Composite in since that lead goes to the Luma pin.
