Step 20Add Video and Audio Wires
What you need:
Hot glue gun
Soldering Iron
IDE Cable or other wire
Once you have unscrewed the screen and tested it, you need to add the audio and video wires.
Unplug the two connectors at the bottom. You only need to keep the left one. We'll use that for power later.
SOLDERING THE A/V WIRES
Flip the screen to the back and find the small pads near the bottom-left that say EXT_V, EXT_R, EXT_L, HP_L, HPS, and HP_R. EXT_V is where you solder the video wire, EXT_R is right audio, and EXT_L is left audio. For the NES, you can short the L and R on the screen, because the NES is mono.
SHORTING THE HEADPHONE WIRES
If you tried to test it at this point, you would notice that there is no sound. You need to short together HP_L, HPS, and HP_R. Otherwise, the screen thinks headphones are plugged in. If you want headphones on your portable, do not short those three pads and use the headphone jack that was included with the screen.
Once you soldered the wires, put some hot glue on them so they don't come loose.

Wait, what would I do if I wanted sound when you plug in headphones and when you haven't plugged in headphones?

Just wire the headphone port to the speaker outputs, but you'll have some impendance mismatch issues. One will be much louder than the other.

You say the NES is mono, which is not strictly true. It can be modded to output "stereo" sound, though it usually sounds quite odd. I know most people don't care, but I thought I'd bring it up.

XCVG, did you join just to criticize me? :P Just kidding. I know you can mod it to be stereo, I may add that tidbit of information.

I'm using a portable DVD player screen that runs of 5 volts. I found the ground wire and the power wires, but I can't see anything like EXT_V, EXT_L, or EXT_R. Any suggestions? I think I am going to probe around and see if I can make it work.

Those connections are for the PSone screen only. Your DVD player screen needs AV input to work for this.
