Wild Things PSone LCD to PC
New to this forum but I will be a regular no doubt. First thank you to all the people for posting the info regarding the PSOne LCD mod, I think this is one of the best PC Mods/Car Mods to date and shout to Starfox for his write up.
Being impatient I bought what looked like a cheapy PSOne screen from eBay however it turned out to be just that... cheap. It's a Wild Things PSOne 4" LCD Monitor but the internal build quality is really bad, probably done in a sweat shop or a knock off factory. I don't know who the TFT is made by but it looks like a cheap build but sturdy and has three small pots for adjustment.
I want to wire this up but I don't know if it can be wired up via the method employed by Starfox and others i.e connecting it to a VGA cable as the board looks very basic in design compared to the Sony version (far less IC's). The back panel is similar to the PSOne as shown on Starfox's site however it has an additonal cigarette lighter socket and two Audio jacks (I think they are audio jacks only, not the Audio/Video as found on the official Sony ones). Looking at the back the circuit layout is very similar to the official Sony version which is why I am thinking it could possibly be wired up to a VGA cable but the board has a white label marked RGB so I am assuming the Wild Things board is RGB/Composite only?
The unit comes with two front mounted switches for power and one that lets you select game or AV input (this is a plus as I can use the switch to manually power on the device). The device also comes with the two speakers (which I am going to cut off as they are not needed) and seperate pots to control colour, brightness, tint and volume.
I would appreciate any input before I start to hack this to peices, if it can be wired up to VGA I will be happy otherwise I will go for the TV Out from a PCI ATi card (I am already running two monitors from my 9800 Pro AGP card).
I also have a spare RGB cable that was originally used for a graphics monitor (has VGA at one end and five BNC wires at the other end, Blue, Red, Green, Black V sync and Grey V/H sync) - would this be a good alternative to wiring up the PSOne screen rather than creating a cable from scratch?
For power I am using a hand built internal PSU to PSOne power connector, I bought a DC to DC cable from Maplins and a Molex extender (female, male, male) and connected one male molex to a female molex (single cable) that I had butchered so I only had the yellow wire and the black wire (12v + ground). I took the the yellow wire and fused it (can't remember the rating, it was the smallest I could find), I took both the yellow and black wires and soldered these to a female DC connector (from Maplins again) which has a nut fixing. I too a blank PCI slot cover and drilled a hole 10mm hole in which I mounted the female DC connector - so I had the following:
Female DC connector >>> Grnd Wire + 12v Wire >>> fused 12v wire >>> female Molex connector attached to a three-way Molex extension.
I took the DC to DC wire and connected this to the DC in on the PSOne monitor connector, hey presto I have 12v power and the monitor fires up! Later on I will remove the PCI plate (used for external connections) and route the power internally or take my next idea of ripping the guts out of a CD-ROM case and using this to house the circuit and power leads for the monitor.
Pics below to give you guys an idea of what I am dealing with (sorry for the quality, my digi camera is dead after my son decided it looked better in our fish tank so I am using the camera built into my mobey).
Thanks in advance,

A shot of the circuit board, the chip in the top middle is surrounded by pots and resistors and I am assuming this is the RGB controller.

The rear connectors, left black is power, yellow next to it is for a 12v cigarette lighter connection, a connector for the Sony AV lead, what is supposed to be a AV input from a DVD or other AV source and the right most connection is for Audio (head phones I think).
The two switches, left is power and right is for Game or AV
The LCD screen in all its glory, I gave it a good old clean so it would shine! You can see the invertor circuit attached to it.
The circuit board (sorry for the fuzzy pics) and as you can see its quite a basic board compared to the Sony one... the four pots, two blue pots for colour and tint and two wheels for brightness and volume. Those square white things were used to hold up the LCD screen away from the board inside the plastic housing... tacky design.
The back of the LCD.. see what I mean by cheap design, I think that foil stuff is to stop any interference.
The LCD in all its glory... you may have noticed I took the plastic screen that was mounted to the white housing and fixed it to the front of the LD screen.
