Just a quick update. I performed the PSOne LED Mod to my screen to save battery life, and because the the backlight burned out. It went fairly smoothly, though I blew out a few leds. Most things I’ve read recommend a 20ohm resistor, which seemed insanely low. I ended up going with 100ohm, which gives me a very visible level of brightness. I used four LEDs instead of the typical two.
I also removed the backlight fuse, and cleaned up the electrical tape that was all over the other wires on the portable.
