VideoNintendo AV outs | PS1 Screen Backlight Mod | PS1 Screen Brightness Video mods useable with generally any system and portableThis page sucks right now. It will get better. Getting different video types from a Super NES/N64/GCNSubmitted by SpongeBuellDisclaimer: I have not performed any of these mods and cannot guarantee that they are 100% accurate. I do not take any liability if you damage your console. These mods are designed for a Super NES, but I assume that they are compatible with the N64 and GCN because they use the same A/V plug. Here is an example of what pin is what on your system. Click on the photo to get the pin numbers, which you will need for following steps. (sorry I didn't get a picture of the Gamecube, but I don't have one. If you can't figure that out on your own though, I would suggest learning a bit more about electronics and stuff anyway.) Update: it has been found that RGB will not work with a Nintendo 64 without modification. Chances are, this goes for the GCN as well. Original SNES's, however, should be fine.
Ground:The ground is attatched to pins 4 and 10. You shouldn't really need a diagram, but I am going to give you one anyway.
Composite Video, Audio:Composite video is pretty easy. Simply connect the center of an RCA plug to pin 2, and ground the outside. Audio is pretty much the same. Use pin 1 for left audio, 7 for right, and ground the outside of the plug.
Luma, ChromaIf you have any plans on having S-Video out on your portable/project you will need to know where how to get luma/chroma outputs. Pin 3 has Luma (intensity) and pin 9 has Chroma. (color)
RGBIf you have a LCD with RGB input, this mod is for you. Connect a 200 uF capacitor to pins 6, 11, and 12 and the other end of the capacitor to your LCD connecting point. After you are done with that, add composite sync and you are done. The n64 doesn't have rgb output, but it can be hacked to do so. I'm not quite sure about the gcn.
+5 volts outputThis isn't really needed, but I have heard a few monitors require 5 volts to stay on, so it's not entirely useless. You can also connect low-amperage things here, such as power LEDs. All you need to do is wire up what you need to pin 10. Don't forget to ground what you are using this for if you want it to work.Hey guys, this is Ben Heckendorn, you know, the runner of the site who occasionally pops up so you know I'm not dead. Anyway, while working on my next ALL-NEW portable system, I made a discovery regarding the PSOne screen! Long ago I did a LED backlight mod to my screen and I know quite a few of you have adapted it. While it DOES work and lowers the power usage by a lot, it's not very bright. WELL, NOW THAT HAS CHANGED! Strictly by accident, while holding the PCB of the screen, I noticed by putting your fingers on certain places it changed the image. The horizontal position, the colors. If I licked my finger and touch the middle of the board, the whole image got way brighter (as you can see, I'm incredibly scientific) I narrowed it down to ONE surface-mount component. I placed the JPG on my website, use this link to find it: [acually, it's right here. -abbibi]
This is the middle of the back of the PCB, and the top of the photo is "UP". Short out that little resistor, capacitor, whatever it is (I have not clue!) with a bit of wire (so it basically "isn't there") and you will see a SHOCKING increase in brightness. The contrast goes down a bit (the blacks are less black, the edges of whites are less sharp) but it's SO much brighter I'm pretty sure you won't care. The brightness control actually seems to DO something now (instead of having to be all the way up, you can now center it). I use a 22 ohm resistor hooked to the 7.2 volts in on the screen, that resistor then goes to (3) 3mm white LED's (Digi-key part CMD204UWC-ND) wired in parallel placed in the lower-left, lower-right and upper-right corners of the screen. It draws 310mA at 7.2v. Ok, well I'm sure any of you with a modded PSOne Screen will have fun with this. Remember, I am still around and trying to get projects finished so I can get back into portables more!
