ask DD on here, or just remove the silver ring, cut out the pastic under it, cut some plexiglass in the same shape and fit the psp logo into it then into the door. if you want u could just a lot of little holes in the circle tho but u still need to remove the ring. you can buy a new one tho for a few dollars.
oh and leds is well same solder points as usual, the resistor on the powerboard and the ground point ther as well.
