Modding PSONE LCD Mod

Hi, I've just joined bit-tech in an attempt to get this display to work. I've read the whole thread twice, but there's no solution to my problem there, so I'm hoping someone can help me out. I have a pal screen with the 7.5v 3A adapter, and get no display. When it's on, all I get is a quiet high pitch whine and the screen goes slightly blacker than when it's off. It's connected to a Matrox mistique, which windows recognises and displays an image onto when I plug my crt into it. The timings in powerstrip all work, as when I plug in the crt with it active, it says "out of range" because the frequencies are too low. I can't get the volume or contrast to display either, so I am thinking it could be a power issue. I have soldered directly from the video card to the screen, without the sony pcb with the ps one connecters on it. The wiring seems sound, as I've triple checked it with a voltmeter. I'm ready to start throwing things out the window here, nothing seems to work. Any help would be greatly appreciated.

i think you are ou of luck, no one seems to be reading this topic anymore, my queston, another guy's and yours will probably never be answered

i can't get an image on mine, but it actualy turns on (i have no c-sync, but i thought that i would actually see something, but not correctly).

so i am stuck with the tv out for now.

 

Sucks, huh? Anyway, I managed to get a clean 5v signal off one of the grounds on the board, and routed it through pin 9, which activated it. I now have it working with a fair display, but not great. If you have any problems I might be able to help with, I'd be happy to give it a go. Thanks for the reply anyway.

 

made a cable myself, and i thought it DIDN't work (not fully) and i thought that i was only missing the h-sync + v-sync > c-sync adapter.

BUT, i tryed the lcd ALONE, without a monitor, and imaage came up (cutted in 4 pieces due to the lack of the adapter).

i wonder why when i try to go dual monitor, the display turns on, the "black cut" that is in the midle of the images when i try it ALONE is visible, but the image wont apear.

i'll try a second monitor on my gf6600gt to see if it has any problem with the dual display mode using the 2 dvi ins (with an adapter gor the 15 pin conector).

 

i tryed 2 crts and they work just fine.

only the lcd and i get image.

lcd + crt = lcd turning on but no image :/

EDIT: changing from the 2nd crt to the lcd once windows has loaded gives me image... i don't get why it can detect and send image to it ALONE but not with another display...

but something worse came up, i can get the pixel count down to ONLY 25k, when i need 15

so i can only try to get myself a pci VGA... i have a friend with a vodoo banshe... a matrox will be IMPOSIBLE arround here.

 

A Matrox is by far the easiest way to go, I got one off of ebay, don't know if that's an option for you. Sounds like your card doesn't support resolutions and frequencies as low as 15, are you sure interlaced is selected (it would have helped if you had the option of c-sync). You should definately try different cards, that's where most people's problems lie. By the sound of the image you're getting, your wiring's alright, just the software side of things needs fixing.

 

yep, my card won't work, or so it seems.

there is a matrox millenium II available, it has no c-sync or so i think, but i can build the adapter.

then there is a "matrox unknown" with "matrox MGA" writen on the core (or so the seller says).

the second one is REALLY cheap (25 argentine pesos = less than 10 u$s), but i haven't heard of that vga before, dunno if it will work.

e-bay is not an option.

 

Hello,

The link on the //starfox.ucc.asn isnt longer active.....
Does anyone know where to find more info about modefy the Thrustmasters one.....

Thanx.

GMM.

 

Firstly, I'm pretty sure the link does work, it's just temperemental, try it every few hours and you might get through.

About elmodder's card: The Matrox Mystique I have (it has c-sync) has mga written on the chip, so It might be the one.

 

i0ll take my chances and get that matrox "MGA"

 

Hehe - just read the whole thread - got a few ideas from it. I have the VGA soldering done but can only get a single screen on the LCD chopped into 4 pieces but it is barely readable and that only works on the primary adapter on 9600XT AIW. Tonight I'm going to try booting the CRT off the primary adapter then switching the LCD to the primary adapter (HOT SWITCHING - EVERYTHING MY MOTHER TOLD ME NOT TO DO!) and hooking the CRT to the 2nd adapter to see if I can get powerstrip to seen the 2nd adapter/monitor then . . . and once I get Powerstrip set, swtiching them back - WHEW! Matrox Mystique if that doesn't work. I'm also bringing home a 32Mb Radeon 7000 as a 2nd PCI adpater to try - but that doesn't look like it will work after reading this whole thread.

 

Man, I have THE shittiest luck...

I got my screen a few days ago, and I'm keen to get it working, so I pull the soldering iron out and my multimeter to test the pins on the cable I bought...

Soldering iron breaks, take it back for the same brand (FYI: Cold Heat)
Second one is pre-broken (second hand), take it back to get a 3rd
This one is faulty ("On switch on all the time, unknown if anything is soldering), so I learn my lesson and today, returned it for a refund, went to a diffrent store and got a proper soldering iron (which, with stand and a 12" heat shrink, cost less than the Cold Heat).

So I finally start soldering, and go to test the monitor out. Huzzah! Backlight comes on!

I figure that some of my pins aren't soldered correctly, so I pull my multimeter out to test... AND IT BREAKS! THE BLOODY GROUND TIP'S WIRE, SOMEHOW, BREAKS AND PULLS ITSELF OUT OF THE HANDLE!

Now I have to go BACK to the store, the SAME STORE I had bought the Cold Heat from, and GET ANOTHER ONE.

Thank god Canadian Tire doesn't ask any questions.

Meanwhile, Does anyone know how to make a ghetto multimeter?

 

I believe the chopping into 4 pieces IS suppose to happen, you just have to screw around with Powerstrip until you get everything fixed.

 

That makes sense. So when I try to hook up the CRT to the 2nd Adapter and get it working, I should be able to move the Powerstrip program over to it so I can actually see what I'm doing, correct?

 

Delete plz, Firefox screwz0rd up

 

Not sure, infact you may want to ditch what I said. I read earlier on in the thread that changing vidcards may make it work. Check page 3 or 4, not sure sorry.





Ok, I was able to make myself a ghetto Multimeter using an analogue clock, a battery and 2 twistie ties. the monitor cable that I bought has a pin layout of this:

red = 1
green = 2
blue = 3

purple = 9
black = 10
orange = 12
clear = 13
white = 14
yellow = 15


Whiskey
Tango
Foxtrot
?

Might as well wait until tomorrow, buy myself a 1m Cat5 and a 15 pin male connector. Bloody hell..

 

you just need pins 1, 2 and 3 for R G B.
6, 7 , 8 for GROUND (the 3 conect to the only ground pin on the lcd)
13 for H/c-sync
9 for dcc+ (only needed for pal screens and some vgas that won't detect without it, don't know which ones).

if your VGA does not supert C-sync, the screen apears splited into 4/2 parts, or with a black "bar" somewhere.

you can switch vga, of make the h-sync + v sync > c-sync adaptor.

i was going to do that, but my vga can't get low enogh on refresh and pixel count

PD: pin 14 is for V-sync, needed for the adapter.

 

Yeah, but if you relooked at my pins on the cable, I have NO ground. Which possibly makes this a very dangerous cable...

either way, I'll make a cable myself today, I've have enough of playing around with this cable anyway.

 

Ok, what I have done is made my own cable using a Cat5 and a Male connector.

I have my primary monitor plugged into the DVI port via VGA adaptor, and my screen plugged into the primary port.

Certain things happen.

My card (Sapphire Radeon 9600 Pro) won't recognise the monitor in the primary port. I can get it to if I, in ATI Power Tools, go to Display > Settings then turn on the TV. What I do then is turn on the DVI Port (which will, for some reason, activate the First and Second VGA ports), make sure the second monitor is default, and click OK. What will happen is that my default monitor will revert to 640x480, but with a moving resolution (aka, it's actually 1280x1024, but showing only 640x480 at any one time)

This will show a scrolling picture in my LCD screen. So basically, I can only get it to clone at the moment. If I change any settings in powerstrip, it'll **** up my main monitor.

I reinstalled my ATI Control Center as it was ****ing up, will update with situation, if anyone knows how to help with getting it working on 1 vga card, lemme know



Editupdate: I rechecked my soldering of the pins, and found that some of the wires came out of their sockets, so I resoldered and redid the above, no dice still
