Modding PSONE LCD Mod

What might be the problem?

I have Joytech 7" tft screen. I would like to connect the screen from my Radeon 9800 Pro s-video output, to Joytechs av in.
Should it work?

When I try this, the picture is not clear. There is red stripes and mystical boxes and shapes everywhere...and the picture is not really recognizable. If moving mouse cursor, it is possible to see it moving sometimes from up to down.
I chose from the graphic settings a secondary screen in use...and i chose the lowest resolution and color 640 x 480, 256 colors.

Do I need Powerstrip to get it work. I suppose it shoud work straight because I use av-in connection.

I am using this kind of a plug in my Radeon s-video output; http://images.amazon.com/images/P/B...ACK-TO-SVIDEO-PLUG-CONVERTER._SCLZZZZZZZ_.jpg

Rca cable is connected to Joytechs screen. Anyone who knows solution?

 

Hmm, if Windows decides the same for me I might go this route. Thanks!

 

got it to work on composite.. but its B&W.. any way yo make it colour?

 

Well, the screen works ... here is the problem. I cannot get my X800 PRO VIVO to output on the VGA port (where LCD is connected to) without first connecting a true monitor.

In control panel, I try to extend the desktop, but it just reverts back after I click 'Apply'. Is this because X800PRO doesn't support Csync?

Any help on this matter is appreciated.

 

Wire colors..

Hi!

I tried to make VGA-mod too! I opened my joytech screens PSX multi av and found out that "there is more wires than shoud be".
-red
-blue
-green
-orange
-white
-black
-yellow
-brown

- I connected red, blue and green to the correct VGA pins (1,2,3).
- I connected the yellow to the ninth pin of the vga (dcc).
- Black is ground..isnt it? I connected it to the VGA 6,7,8 pins.

Whatabout the white, orange and brown?

When starting the computer..windows recognizes it as a monitor. I can see that there is a desktop...but the screen is flickering! I installed powerstrip and chose PAL&Interlaced..was it something like 720 x something. It doenst help. Screen keeps flickering.

If someone could help me with this problem. Is it in the wireing or something else?

EDIT: 2006-27-4; Yep..woke up this morning and started to find out answers for my own questions
First of all..I red the first page again and found out what the "weird" colors are. So I connected R, G and B in the right pins. Black and yellow are also connected in the right pins. What I did wrong was that I connected the brown wire from LCD to C-sync in VGA. It should be the white wire from LCD to the VGAs C-sync Pin.

I will try to change it later today..and I hope that it makes the flickering go away..

 

I'm finally able to get a picture on my psone screen. It still has some diagonal lines which shouldn't be there but that's not the problem. I can use the screen, I can even use msn on it without a magnifying glass but my screen seems to only use the blue data it gets. Everything is a shade of blue. My background (the one with the green grass hill and the blue sky) only showes the blue sky (without the clouds) and the grass section is black. I used my multimeter to check if the connection between red / green / blue line isn't broken but every cable gives a positive signal on it. Does anybody know what it could be?

EDIT: I made a small paint file in which I have a red square, a green square and a blue scare. The red and green squares are displayed black and the blue square is displayed white or very light blue. I know the lcd can display red and green because when I tap on the vga cable i can get red/green stripes

 

something is up with the cable or the cable/card connection.

 

that's the strange thing. I measured to see if there is a connection between the board connector and the vga pins and every pin seems to match to the correct wire. I also checked each pin on the vga to see if it doesn't make contact with other pins but that's not the question (except ground pins 6-7-8)
Don't know what to do now actually

EDIT: got it to work. It seemed that the wiring scheme I was following from a website was inverted. The blue being in the middle of the row was the only correctly placed wire (along with one ground and the csync)

 

is your card made by nvidia or ati?

 

I got it to work But it's a matrox millenium.
When I finish building it in my case I'll post pics to persuade all the others still considering wether or not to do it.

 

all I need is to force my card to output on VGA, whether or not it finds a monitor there ...

x800 btw.

 

OK, so I have a LCD wired up and running. Now, I can not have csync or interlacing checked in powerstrip to get an image. But I do have to turn off tiling. but as soon as I do that I can not play games like counter strike. My main monitor goes out of sync.

Main video card is ATI Radeon 9800 pro 256 meg, secondary card that has the LCD connected is an ATI Radeon 7000. Any thoughts ?

 

Just thought id post pictures of my PSone LCD, as it isnt the offical one, it is the one made by Competition Pro, commonly available on eBay.

a warning to people wanting to do the VGA Mod to it, it uses two circuit boards, and a different design (obviously) to the offical one, so do what i have done, and hook it up by SVideo (which is what i intended to do before buying it)

here are the pics:

Warning: Stupidly Large Images Linked!





as this is being used outside my pc case, i have made a wooden block that it screws to. it will be going inside a PC at some point

 

ok, im stuck...
ive read most of this now massive thread, got a lil confused, and a large headache...
ive pimped up me screen, its connected by s-video-rca-3.5mm to me gfx card geforce 6600gt... problem comes when i try getting the screen to turn on... i havent touched anything on the pcb itself it is as new, and there is no power gettin to the screen, never once had any flicker either before or after taking it apart etc.... the monitor is detected in windows through me driver, so i reckon it should be showing somin.
i was wondering if ive missed somin, or i just have a dead lcd/backlight....
im using the power adaptor that came witht the screen not the cigy method, so i figure it should work fine!
i have a pal screen, and s-video connection, if anyone coudl give me a hand id be over the moon
cheers, steve

 

Hi,

I have made the vga mod for the psone and it works as seconday screen (extending windows desktop)with my ATI Radeon 9250, using powerstrip.
I tried the dcc mod with the 24lc21 chip, but it does not worked (continue investigating).

I would like to use my psone screen with my carputer. The carputer would only have the psone screen connected. So my question is: Is it posible to use the psone screen as main monitor? or as seconday monitor (not extending windows desktop).

I request excuses, my English is not very good

 

Hi,
My english isn't good either.
Vincente, do you have the original PSone LCD?
I've got the Competition Pro.
I wan't to use VGA, but I guess it isn't possible.
Anyway, i've got a few left .. but I only need 1.

 

Well, as most of you should know, I am attempting a new mod.

It is very similair to this:

>>PSOne LCD Mod<<

My mod, however, varies in a few ways.

1) I am not using the standard, Sony PSOne LCD.

I am using this type: (Produced by Intec)


2) I am going to use the included RCA input module, and use my S-Video to Analog converter that came with my 9800pro(Although I now use a x1800xt 512) to transfer the video from my videocard, or just use the RCA input for my Dreamcast. (I hope to make it hot-swapable)

3) I am not going to use external power for the LCD, I plan on using a Molex (4-Pin) power cable to power the LCD. The problem for now, is that a Molex cable runs at 12v. The included AC-DC adapter (For car use.) has a transformer in it that converts the 12v source to a controlled 7.5v @ 2amps.

4) I plan on mounting the LCD in two un-used 5 1/2" drive bays, using the plastic covers to mount the LCD, and store the circuitboards that the LCD uses in a plastic box in the bays. This shouldn't be the hard part.

What I need to know:

Can I simply take apart the car-adapter and imput the +,-, and ground wires straight to the transformer circuit? Will that work? I don't wanna blow another PSU. >.<

*Sorry if that is redundant in any way, but I copied it directly from my own forums, http://www.gigayetti.com .

Is that an alright way to get power? I really wanna know before I screw up my LCD.

 

Hi Jossie16,

I own then original Sony PSOne LCD. Bought on eBay.

 

Here are some pictures from my WIP....

I am testing just using the 12v lines from the PSU, but I needed an old (K6) mobo to ground the line for the PSU to fire. >.<

Tell me what you think!

 

I bought 10 fake ones for just €23x10.
I allready sold 6 or 7 of these and I want to have one for myself to mod.
