Modding PSONE LCD Mod

are you sure? becuase I don't want to cut a hole in my case just to find out that the 7800 GT won't support it.... I heard bad things about nVidia and C-sync?

 

wire it up and test it then u wnt have to cut up ur case

 

I wouldn't bother using VGA for nvidia cards, especially the newer ones, just go for s-video.

 

lucky im not using nvidia card then lol

mr willywonka what should i do about the prob i have with my screen

happy new year everyone

 

The connector isn't upside down, it's reverse to what you see. So basically you solder to the opposite side to what the picture shows (It's best to look at the pins from behind rather from the front).

 

so u mean like this

 

Oops, sorry no. I thought you were talking about the VGA soldering rather than the PSOne screen itself.

If are looking at the underside of the small PCB , you solder onto the points shown in the tutorial, as that is the solder side.

Sorry for the confusion!

*How can your solder side be upside down? Do you have the official screen?

 

omg that looks so sexy, wish i could do that on my coolermaster case...

 

no mines the logic 3 screen.

the pic for my screen is tha way round on the solder side. there is one that is the same shape connector as the one on the psone console that the soldering is the same as the tutorial. if i solder to that will it work?

 

N/A - I have just hooked my PS One LCD up to my brand new PNY 7800GT card. I used the s-video out method, and followed the instructions on MrWillyWonkas site - hats off to him

Now I just have to work out what i want displayed on there, and more importantly - how I think I will try the samurize route, but might see if I can't get some of the latest Konfabulator/Yahoo Wodgets to work on there as well.

 

ok well i figured that i might as well post this here instead of littering the forum with yet another PSOne LCD problem.

i purchased a NTSC PSOne LCD and am attempting to hook it up via VGA. i have read this whole post and a few other long ones related to it and have combined bits of knowledge here and there to wire it up properly. the video card that i am using is a ATI Radeon 9600. here is a diagram and a few pictures to hopefully help in figuring out what is wrong.

the problem: it seems quite simplistic however i am lacking alot of sleep from work and i need a fresh eye to look at this. the LCD powers properly when plugged in. the computer immediately sees it as another monitor. i have tweaked the settings in powerstrip to the best of my ability so the screen does not flicker/scroll/twitch at all. the picture fills the whole screen and is basically flawless except for one crucial area. the colors/brightness/contrast are all screwed up. they are too low to even make the screen usable. in a panic i plugged my gamecube directly in to the LCD to check and see if it was the input/cable or the screen itself. the colors and brightness on the composite in are perfect. so i leave this mystery up to you fellow bit-tech modders: what is wrong with this setup? many thanks in advance.

straight shot (actually looks better straight on in person).


on an angle (easier to see the problem from here).

thought of another question for those of you who have been modding these things longer than i have. where is the backlight circuit getting its power? i would like to know this so i can attach a switch to it and turn the light off, kind of like shutting a laptops lid.


any-who its just something to ponder...

 

Interesting to see someone actually do this. Good to know that it does detect the LCD when those resistors are added. BUT, I'm thinking the resistors are the reason for the problem you are having. I'm assuming that you dont have a second video card to run this on, hence the force detection resistors.

Take the resistors off and hook it up to a second video card and it should work well. I suppose if you are really bold, you might try plugging that in as your only monitor and then use XP's remote connection tool from another computer to tweak until you are able to use the PSOne LCD.

 

unfortunately i do not have an extra PCI video card lying around and i would like to try that only as a last ditch effort to get this working as it would not be easy for me to add another PCI card to my server.

i thought i saw someone use the resistor method in another forum and they seemed to have loads more luck than i did however i cannot remember where i saw it or the resistance that they used. i thought it was something like 220 or 270 ohms however i am unclear on this. if anyone has tried the resistor method for detection and had some success please post the resistor values. it would help me and many others i would assume.

tomorrow i will try a different value for the resistors and see if i can get anything to work out better than this. until then,

The only way to tell is to use a multimeter I think, or to ask someone else who has a logic screen :/

Thanks! I thought we needed a clear guide on s-video as no-one has explained it properly here or anywhere on the web!

Samurize is easy to configure. You can use nexxo's config (samurize site is down for maintenace, so you might have to wait before you can download it!). Once downloaded you can edit it yourself for your needs, I have got mine exactly how I want it! (Different to the one shown in the pic).

You can use widgets, but they won't fill the screen up so much.

Well, a VGA dummy uses 70Ohms on the rgb wires to ground, I and a few others have questioned whether it would work if we actually used a resistor between each rgb and gnd whilst rgb was connected to the psone also, but none of us tried it. You are the first I think that has come along and done this. Are you positive someone has done this and not a vga dummy?

Afaik, ATI cards are less problematic with the psone mod and the Radeon 9600 series seems sucessful, without the resistors, so give it a try.

 

ok i have wired up the screen

problem is im waitin for powerpack to be deliverd so cant see if it works lol

heres some pics

 

yeah i am positive that someone on another forum has used resistors to ground the RGB signal lines to ground. i just cannot find that post. i origonaly found it via a link from this forum and it is getting to be rather frustrating.

i have tried to use the psone screen plugged straight in to my Radeon 9600 and it was not working out for me. every time i would change the resolution or color depth the screen would flicker, go out and i would have to then attach a spare LCD so the video card would re-initalize that port. i fought with it for about 4 hours trying every thing i could think of. that is why i sought to try the VGA dummy + PSOne method. i think i am close though. i will try higher resistance tonight. it looks promising though. when i plug the screen the video card immediately thinks that there is something there and starts sending signal. well id better get back to work .

 

ok so now i am fedup. powerpack comes today. hook it up an nothing.... reopen the caseing on screen to see the lil fuse in it has blown. so will this mean the screen is screwed or is it a trip to maplin for a new fuse..ive checked the website they have them. so just have to wait till tomoz to get one

 

MrBurritoMan, how did you get those motherboard tray risers screwed in? Did you just force them in? Because that's a brilliant and very clean method.

 

Problem with PAL PSOne LCD On X800 VGA... Please help!

Hi there.
I have a PAL PSOne LCD.
I wired all the pins up as directed in the original article.
I double checked them.
I have a Radeon x800 XT with my main monitor using the DVI Out.
I plugged the LCD into the VGA socket, but...

Windows won't detect the LCD.
I tried rebooting the PC and nothing happened,
not even a bois message. (Althought the LCD does power up).

Any suggestions?

Does anyone have the LCD working well on an x800?

Cheers,
Dan.
