Now, I simply poke holes in the bottom of the light diffusing box (using the LEDs leads with a soldering iron to heat them through the plastic) where I want the leds to go, and simply wire them on the outside, on the back of the backlight module. it's WAY easier, and it takes me a short time to LED mod the psone screen
here's a pic showing what I mean. the black dots are where you'd poke the LED leads through, and the ovals would be the actual LEDs:

just posting this to show a different way to easily wire up LEDs on the PSone screen, if you're having trouble
