Changing the Green PLAY button's LED's into DVJ-X1 Blue

This mod was suggested by Nightmoves in This Forum thread. "Is it possible to change lights of the cdj 1000mk2's start/button to those of the dvj. Would be cool to change it, since I'm just a sucker for the dvj's blue lights."

I gave it some thoughts and figured out that it might be neat to exchange the regular GREEN Led's around that Play/Pause button into the blue ones from the Pioneer DVJ-X1. They seem to have the same specification for the LED's, at least for what I could find out so I took my chance. I can never suggest anybody to do this.


I ordered 4 LED's that are used in the Pioneer DVJ-X1 :

Part number	Description	Price excl. tax (BTW)
SLR-343BBT	D4207 - Blue LED)	7 euro/piece, 4 needed

Be careful when opening the CDJ-1000mk2, do not put the top directly on the table, but put it on a towel or any other soft surface. You might make a scratch on the display when you put it right on the table.

Change the Led's

When you've unscrewed the bottom side of the CDJ1000MKII, you can open the backside like a book (when the slot-in is towards you). You will see in the control panel that holds the Play/Cue and search buttons in the bottom right corner. Look for the section that holds the Play Button LED's, like shown here.

In the red circle you see the section where the LED's are mounted. Their exact location is clearly printed beside the mounting points on the circuit board..

The parts to be replace in the CDJ are D1305 ~ D1308 (SLR-343EBT). First desolder the LED's, than remove the circuit board and replace the LED's. Use the welding touch shortly so you don't burn the LED's!

Transparent LED's

Some basic information regarding LED's. LED is actually short for Light Emitting Diode.

A LED is a diode, an electronic component that only allows a current to flow in one direction. You need to know that an LED consists of a chip of semi conducting material impregnated with impurities that create a structure called a p-n junction. While the current flows through the junction there will be produced light.

The wavelength (so the color) of the light is determined by the type of p-n junction is used. The outer epoxy shell around the p-n junction can be fitted with a lens-like top that can bundle the light.

The color of the epoxy shape of the LED has only little influence to the color of the light which the LED emits. Nowadays most LED's are made of transparent epoxy so without powering them it's hard to tell the color

This type of component is used in lots of gear and equipment, it's the most affordable and reliable solutions to create light in the darkness. And besides this, the LED is also used this much because of it's efficiency.


Just for the looks
There is no real practical use for this modification of the CDJ, but is sure makes your deck different from all others.

Here is an image of my CDJ-1000mk2 that gives you a complete overview, the blue LED's are clearly visible... and combine perfectly with the DVJ-jog modification
