Notes on Parts Replacement
(1) Detachment/Reattachment of the front panel
For replacement of the CONTROL PCB Assy A/B or MIX PCB Assy, the front panel must be detached.
The front panel is secured to the Chassis Assy with double-back tape at 4 locations for prevention of lifting. Be fully careful not to deform the
B
front panel when detaching it.
For details, see "g About the double-back tape that is used for securing the front panel and the Chassis Assy" in "[3] Each PCB assembly,"
"7.DISASSEMBLY."
(2) When replacing the LED & COVER Assy or WHEEL Assy of the JOG dial section
When replacement of the LED & COVER Assy is required, the Windows Lens must be detached, because the Windows Lens is attached to
the WHEEL Assy with double-back tape, which is attached around the outer periphery of the Windows Lens as a tube, and the LED & COVER
Assy is placed in between them.
Once the Windows Lens is detached, the double-back tape cannot be reused. The Windows Lens may not be reused either, because it may
be scratched, depending on the manner in which it was detached.
When replacement of the WHEEL Assy is required, the Windows Lens must also be detached and may not be reused.
Note that when replacement of the following Assys are required, replace them together with the parts mentioned below.
C
Double-back tape is supplied with the WHEEL Assy.
· When the LED & COVER Assy is to be replaced: Double-back tape (TWIN ADHESIVE) (must), Windows Lens (if necessary)
· When the WHEEL Assy is to be replaced: Windows Lens (if necessary)

(3) When replacing the USB JACK
When the USB JACK in the DSP PCB Assy is to be replaced, the USB fixing bracket (USB fixed plate) must be detached
together with it. To detach them, remove the solder from the JACK and USB fixed plate.
For improvement of durability, the JACK and USB fixed plate were glued with adhesive for the products of the initial
production. (See the photo on the left below.)
In this case, replace the USB JACK together with the USB fixed plate.
The shape of the USB fixed plate has been modified so that it no longer requires adhesive for locking.
(See the photo on the right below.)
E
The USB fixed plate for service is the one after this modification.
The numbers of the products that have the older version of the USB fixed plate (fixed with adhesive) is as shown below:
DDJ-SX/UXECB: 2,000
DDJ-SX/SVYXE8: 418
DDJ-SX/FLPXE: 572
