Modding PSONE LCD Mod

aren´t the 7.5 3A for both de psone and the lcd screen?
I belive that psone alone uses a 7.5V 2A psu and the lcd screen+psone uses a 7.5 3A, so the screen should be consuming less than 1A
maybe I´m wrong...

 

Yeah, that's what makes sense to me, but some complain the backlight doesn't light up or something. Doesn't make sense to me.

 

I've tried with up to 800 mA before buying the car plug and it didn't worked!

 

Yeah, I might just use eBay to find an adapter or something so I know it works.

 

thnxz
i was worried I had done something wrong and burned the screen, but now i hope I haven´t.
I´ll try to get a 3 A psu and try again.

"Thread Necromancer card here"

I have a old 2mb S3 Virge SX/DX pci vid card, anybody tried the psone lcd vga hack with it? Know if it supports c-sync?

EDIT: I guess the last reply wasnt as old as I thought, lmfao.

 

Could any one get me a nice clean pic of the monitor in the bios and in windows using the svid cable plz. If I can get one of these to use in my car it will save me so much money and it is about the right size. If you can take a pic and don't feel like posting just email it to hcker2000@gmail.com

So far I've followed every piece of advice on this forum for getting my PSOne display to work on my PC. But I've yet to accomplish a readable screen.
My setup is as follows:

Asus P4C800 Deluxe
1GB PC3200 RAM
Chaintech FX5200 with Dell Ultrasharp 1800FP connected via DVI
Matrox Mystique 4MB connected to PSOne screen per scheme used in this article
Running the latest version of Powerstrip

The problem is once I get the screen to quit 'rolling' vertically, I can vaguely make out my background image on the PSOne screen, but there seems to be maybe 4-6 slightly overlapping images going across the screen left to right. If I change my backgroung image/color, I can see that the color change on the PSOne screen changes AND to the right color(s)! I've tried adjusting everything, but I never can make out a clear image. I've seen pictures here that show an image in each quadrant, but I don't get that. Mine seem to be stacked left to right, and very squished (640x480 down to 75x??). I've tripled checked my wiring with ohmmeter and all seems to be in order there. I'm supplying DDC (Pin10) with 5vdc from the onboard 7805 regulator.
I also tried FinalChad's settings listed on Page 10 of this thread, but the screen was just rolling with some jaggies on it.

I'm at my wit's end.
Any help is appreciated!

that's amazing, i'm having the EXACT same problem as you, I posted pics in another forum, you can see here:

http://www.mp3car.com/vbulletin/showthread.php?t=44432

the way you describe it, I have the exact same display as you are getting.

I also have the newest version of powerstrip. maybe this is our problem? I'll try an older version... hrmm

I'm using a radeon 9200 128mb

 

Mattress,

You are getting a much better picture than I! Yours seem to go diagonally, mine go straight across. Mine I can barely make out what is on the screen. I'll try to take some pictures tomorrow.

Quick question.

If one was to plug in a second sound card, would they be able to have sound run from the speakers?

Or would a second soundcard screw over the system


Also, if anyone bears to read anything I say, has anyone tried doing it with a DVI LCD connection and succeeded? (Meaning both hardwiring a DVI plug to it or plugging the VGA mod into a VGA-DVI convertor in the back of a vidcard)

 

I tried on my MSI 9600Pro card using VGA-DVI convertor but failed. Only monitor swap trick using powerstrip worked. It depends on your video card. Many people here used second vga card which wasn't option for me(I have SFF).

 

As mentioned by a few other people too, I am having a problem with the backlight not turning on. The display seems to work, I can see faint responses in the image, but they are rather hard to see with no backlight. Has anyone that had this problem solved it? Is there a turn on signal I am missing?

The display is the same as shown in the guide and it is a NTSC model.

 

thats the +5v on the dcc pin.

I have a problem myself, my screen used to function perfectly, its not been damaged, nor modified since, but i now cant get it to work with 16bit colour. its on a pci radeon 9000 vga+dvi card.

 

Would something like this work, i think it solved everyone's soldering problems

i've not read this whole thing so sorry if this has already been answered
my graphics card (radeon 9200se) has an s video/composite socket and can run a seccond screen off it. so if i got a ps2 comp scart cable (the one that came with it) and an in car adapter for the lcd could i just plug the scart into the pc and the lcd then use the car adapter to get it to work?

 

Are you guys using the default windows xp matrox mystique driver or another?

I can get the drivers to go to 640x480 in pstrip, I will add the resolution, and then when i go back to the timings page, its set back to 800x600

 

i got myself a sony lcd, and i managed to make it work with the TV-out of my xfx gf6600gt (dual dvi +1 tvout).

i wanted to try the vga mod, so i soldered everything in its place (checked with a multimeter) and used a cable which doesn't have the dcc pin/cable within.

i know that my gf6600gt probably wont suport c-sync, but i had some hopes, because mine has 2 dvi outs, and comes with adapters for "normal" monitors (don't know the name ), but i wanted to try anyway, to see if i got some kind of image (before trying to build the v-sync + h-sync --> c-sync adapter), but the disp´lay won't turn on / get detected in windows.

during the boot there was some kind of "black thing" diferent from the rest of the display, but it was off (when i use the tv-out the image rotates and is in black and white until i get to windows).

is it posible that it didn't got detected because i didn't suply the +5v to the dcc pin ? i thought that was necesary only in PAL versions (mine is ntsc).

can i suply the +5v from the 5v rail of my psu ?
what must be conected tho the ground of my psu ?

 

Hello everybody.
I know that some people managed to make the mod with a PSone screen from bigben interactive. Do you know any links or any infos on how to hack this one?
Thanks for your help
Michael.
