Thread: Playstation LCD Hack - Works!!

Um... I de-solded it. Going to re-solder it a little later with a new VGA cable.

I also got a 2mb card to test on. *Monster Garage Voice* FREE! */voice*

I too have the dual core RGB wires, like Chewy has.

When you press the volume +- or brightness +-, does the green bar thing come up on screen?

If not, then your screen is not powering. Some PSOne screens require +5Volts to be on pin 10 on the PSOne connector to power on.

Hi Guys,


i have a Sony Brand, NTSC screen.

I made the mod according to Tidder's pages.

The screen refuses to power up, not even a backlight or anything... I thikn I saw a very small flicker of the backlight at one time, but never again have I been able to reproduce it.

Is there anything to test? I cannot confirm that my video card is outputing in an acceptable format, as I was trying it on my laptop, but I havent even been able to get garbage on the screen..

any help?

The back light comes on as well as the contrast bar. I have that plugged in to the power supply still. I didn't want to mess with converting 7.5v from a stock 12v line in a PSU.

My probem, I think was my wire (and soldering). My wire was missing one of the pins... I corrected that with a new cable, and started soldering again. This time, taking a little more time by planning out the wiring better... (big iron tip + little space == big mess). I hope to have it all finished tomorrow and get the screen running.

I have a big set back though... my PC came down with the avian flu. Last Friday I was on my buddy's private server playing Day Of Defeat, and some other places... I came up with seven viruses and about 150 spyware. As far as ad-aware and Norton go, they say it's all gone, but I'm still getting some funny messages on start up... It might be reformat time again. I just did that ~6 months ago.


RoyN: Tidder's screen how-to requires you to have the power connector still plugged in. Unless you modified his walk through to accept power from another source. To simplify things, just make sure you have a valid power source. Once you make sure the screen works with your setup, you can adjust power via resistors, etc to come from a standard 12v source (ie, inverter or PSU).

i was using one of those radioshack multi-voltage wall-adapters... It seems to be putting out about 8v, or maybe even more.... i wonder if I blew the screen...

I hope not though...i have another one to try out on anyways, but does the screen power up with only the power-supply hooked in? (i.e. no vga?)

I might try and get a better power supply, and try it on the new screen, plus all I have to do is dismantly it an switch the ribbon to the new screen, since I already soldered the VGA to the ribbon...

I sure hope i didnt manage to ALREADY screw up one of the screens..

If it doesn't even power on and you have a Sony brand psone screen, have you done this:
Please help. PS1 LCD power wiring?

RoyN, yes, the with the stock plug and wiring, my LCD powers on (even without a vga connection) and I can see a backlight along with the contrast when I hit the up down buttons.

Hey Rob,

I didnt do that no... I just followed the intructions from Tidder... I will try...

Just to confirm, pin 1 = blue on corner, pin 10 = a white near the end of the plug opposite the blue? (just confirming....

Also, I couldnt find a clear descroption of where to tap into 5v on the PS1 board.... for now I'll use my computer PSU 5v rail.

I am having some woes finding a decent 7.5v power suppy... I had one that said output 9v, and was showing 7.9v output, but now it jumped to 18v... this is

I hope I dont see smoke

Turned out I just needed a decent PSU...no mod for 5v required on a NTSC PsONE screen, Sony brand.
