I can't seem to find the tutorial on how to utilize a PSONE LCD screen as a test rig. I would like to modify mine and use it as a test rig. I've searched and came across noise land arcade blog but no actual step by step tutorial. Does any one have a step by step link or could provide instructions on what needs to be soldered etc to make the PSONE LCD screen into light weight portable test rig.

I hacked mine years ago, so I don't remember all the details. I think I used this PDF file to determine what pins to solder to:

That definitely helps. However I noticed on the back of the PSONE LCD it has an A/V IN that looks like a mini 3.5mm jack. Using some various parts I had laying around I was able to create a CGA to VGA adapter (In theory it should work). I wish I could find a VGA to A/V 3.5mm that would work without modifying my PSONE LCD. I tried using my adapter on an older 15'' LCD and got an out of range xga message (Likely doesn't support the lower resolution). It would be nice to find a mini LCD like 4-10'' that's portable that works with CGA and has a VGA input and that's very inexpensive. I wish the iphone would be able to do that with an adapter, I would always have my test monitor on me at all times - the cables / adapters.

I'm still confused by this PDF...DCC ? doesn't it get it's power from the wall adapter ? VGA Pin 9, PSX PIN 10.

I thought I only needed to hook up R,G,B, Ground, Synch. ?

The power for the lcd comes from the wall adapter. The DCC is used when
hooking the lcd to a pc via vga for the timing. You can feed the psone lcd 640x480@30hz(interlaced) but not 60hz vga

The AV-in is for Composite video in,Left and right Audio in only. If you can fine a Playstation Component Cable, you can plug it in the back of the lcd and feed a rgb signal in that way. But you need to have the sync signal to the green wire. This way you don't have to open it up, just make a simple sync on green circuit.
 
well I decided to just go ahead and solder.. good news is I got it working... Even better news it was the first time I got a chance to see my project Burger Time PCB running. I would really like to grab another one this will be incredibly useful as a test rig / out testing games etc.. Perhaps the next one I won't solder and figure out a way to utilize the original a/v proprietary psone hook up and hack that so I wouldn't even need to decase it. My screen had almost no hours on it, even still has the screen protector intact. I figured I might as well use it as this thing was just sitting in my closet.

Sweet! Makes me want to get going on my portable test rig... just waiting on a few more parts. Show us your rig when she's finished.
 
my psone screen is still sitting NIB sans adapter, i also need to pick up more header pins.... (maybe next week).

looks great! any pictures of where you modded it?
 
I've just started modding mine. I desoldered the pass through connector and I am building an adapter using it. Should allow me to use the cable on all PSOne LCD's going forward, so if this one dies for some reason, I can replace it without having to open up the next one.

If anyone has pictures of how they moded their PSOne LCD, it would be helpful.
 
I just got my AC adapter last week, i'll be modding mine within the next few days/week (maybe tonight). I was just going to solder header pins directly to the back and make a molex to molex cable (don't know if i'll be making my cable the way discussed in this thread)
 
nice job, i like how you used the pass thru connector. the sync issue you have is interesting i'll agree.

how well does the pass thru connector stay seated on the screen input?

It fits perfectly, it's not going to fall off and it's not too tight that it's hard to put on or remove.
 
Nice job. I have sync issues with mine as well. Not like you describe, but there are a lot of PCBs I just can't get it to lock in the sync. Do you have any pictures of how you added the caps to the sync lines?
 
Thanks Arcadenut! I didn't have sync issues like you said you did only when nothing was hooked up to my breakaway header pins.



sorry about the sideways video (i really need to stop that)
 
Awesome! Hope you don't mind, I added the YouTube video to my page.

I like the way you did the KK Molex connectors and I think I'm going to change mine to that style instead of the 9 pin.

nope fine with me, thanks for the write up on your site, that along with the pictures made it really easy to do.
