Thanks. I will still need a multimonitor compatable card however - I dont think the banshee will be in win2k, because of drivers...
But it means I could use any cheap multimonitor vga card, if i can find one...
Also good is the circuit costs almsot nothing to make. The 74LS86 chip (Quad 2-input EXCLUSIVE-OR) costs 25p... the other parts cost almsot nothing aswell...
Update - I done some continity testing to find out which pins on the lcd cables goto the vga pins that we need.
This means the connector pcb is no longer needed, you can connect the controler pcb directly to a vga socket (or cable). I will unsolder the small socket on the pcb to connect to the existing wires (instead of cutting the tiny plug off the cable)
Here is the pin out: (IMPORTANT - This is from looking at the bottom of the pcb, the 3.5mm jacks face right, middle connector faces left, bottom connector faces right. Pin1 is the left-most pin.
1 - Csync
2 - VGA Red
3 - VGA Green
4 - VGA Blue
5 - Ground (for everything, this is where RGB ground also goes to)
6 - N/C
7 - N/C
8 - N/C
9 - N/C
10 - DCC (Needs 5v to turn the screen on, make sure your monitor cable has a wire for DCC as some miss that out. DCC is pin 9 on the vga cable).

seeing as its come with speakers, and so recieves audio from the PSone normally, which pins are the audio inputs so i can use the speakers?
cheers

Nope they arnt connected to anything afaik. There is another connector on the pcb which I think has the audio or you could use the 3.5mm imput jacks
4 cables not connected? What's the point of that?

the audio jack is headphone output which is annoying, the psone puts out audio through its weird connector to the speakers so there must be some audio ones. on the back of the main pc above the connector with the red, there are some points labeled audio R and L and a ground, i traced these back to the small pcb now stripped down to points but no joy when wired up. wonder whod know which are which :S
The 'external AV in' jack has stereo audio (as well as composite video) - I've binned that part and have only kept the main PCB and screen but perhaps someone else can trace where they connect to on the main PCB?
Edit: Oops - just actually read the post above... FWIW I have everything connected to the main PCB via the cables instead of wiring to the small 'daughter board' (but I'm only using composite not RGB / VGA)
if you have any of those details they would be useful to have about for those people who mightve busted their daughterboard.
as for the points on the back of the pcb they could equally be outputs seeing as i got nothing out. hm! i was about to do the vga mod today but plugged it into extra jack in my xbox which was fun.
update, i can get the left channel input using the third pin from left in of the top connector to the lcd when looking from bottom of daughterboard 3.5mm jacks facing right. [this is more obvious on the bottom of the back of the major pcb as EXT_L and EXT_R but i get nothing from EXT_R, perhaps the l/r grounds are different or do i just have a duff board?] no right tho

I only traced the vga pins and the pins on the connector to the main pcb. There is another connector to the main pcb with pins I did not trace, this has all of the audio stuff I think.
You may be right, as that also carries the composite signal doesn't it?

Yes - the 'red' ribbon cable (it's red keyed on mine anyway - the other one is blue) that connects to the port on the left of the main PCB (as you look at it from the LCD side) has the composite signal. As TK0 has said though the back of the main PCB has several pads that are labelled (can't remember off the top of my head but there's basically one for each pin on the left side socket) I broke the original cable by accident and actually checked the screen by using these. There's also a pad on the back for +7.5V and several for ground (GND1, etc) so you could (for composite use) solder the the requried wires to these points on the main PCB. I've actually hacked up the connectors from the speakers to replace the 2 larger ribbon cables (and have attached 4 pin molex connectors to them and the supply cables so that I can still take off the front of my PC61 without too much hassle)
well i wired up the vga today and it works but i cant get the powerstrip settings so that the picture is viewable, for some reason it wont let me change the resolution in powerstrip so its stuck at 640*480 even though its a pal screen so needs to be 720*576. anyone know what im doing and why i cant change the res?I try to enter in a new res number but it doesnt change and the res doesnt change by clicking the up/down buttons next to the number either
HI, I was struggling with powerstrip too. You have to go to advanced timings and create the 720x576 res which is not standart. You may find usefull exploring this forum there is a plenty of info on the subject, which card are you using?

btw. Has anybody managed to get stable picture with PAL psone lcd and matrox millenium G200 ? -> I'm stuck in the 'scrolling picture phase' and settings from those tutorials doesn't work for me since they are using ATI timings.. Thanks
yes, people have - not me personally, but a few have
I'm having trouble with the Matrox Mistique PCI - it doesnt seem to put out the 5V DCC on pin 9, so the screen won't turn on (when plugged into my nVidia Ti4400, it will turn on, but you can't sync it) so I'm gonna have to do that "always on" mod to the screen as well. joy.
"yes, people have - not me personally, but a few have"

?Do you have some links or any info to contact them?
Thanks
Btw. With regard to the "always on mod" it is pretty easy, you just
have to unplug carefully display from the pcb and then wire it
with the 300R (100-500R) resistor (there is no polarity) follow the pictures from previous pages or at mp3car site ->
hint: you don't have to solder it to the back of the connector (pin10) there is a tiny hole under the pin (looking from the back/pcb side) where you can plug the cable, that's how I made this mod.. However, the other mods are too risky to undertake with my old sold. iron so I've to employ some more advanced moder fellow :@ )
