Step 20: Add Video and Audio Wires
Hot glue gun
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.
