With the purchase of this kit, I will also help you fix your tray issue. This is very easy most of the time, but there are stubborn
cases when it takes more tricks to get it fixed.
Do you have a Denon CD player with a stuck or sluggish cd tray?
This kit system and with help of this auction, you can fix this problem real
easily in less than 30 minutes.
I am a huge fan of Denon components and especially CD players.
I have owned basically all 4 digit cd players from DCD-1000 all the way up to
the
biggest and heaviest DCD-3560. Over the past 8 years, I have bought, owned,
refurbished,
repaired, modified and sold over 200 of these Denons. I will talk about below
on modifications
I performed on these units. I have noticed that the tray system is Denon's
weakest link.
The tray system gets stuck or become sluggish and I have seen many many units
with this problem.
One of the reason is an over-complicated system of mechanism of gears, pulleys, belts, locking system, spring, sliding surface and more.
Therefore, when
those belts dry up or gets dirty or other foreign elements get in, the tray
starts to malfunction. Eventually, it gets stuck.
For auction is a belt kit system for Denon CD players models:
DCD-1420
DCD-1500II
DCD-1520
DCD-1560
DCD-2560
DCD-3520
DCD-3560
It will for for other cd players that uses the Sony laser pickup mechanism
KSS-151A.
This is an excellent laser used in many very expensive cd players
like Wadia, Esoteric, high end Sony and so on. And of course the Denons.
The belt kit system includes:
1. Belt A 4230046209 (upper deck "skinny long")
2. Belt B 4230047004 (lower deck "fat short")
3. PTFE Teflon Tri Flow oil for metal sliding parts.
4. Two six inch long wooden double cotton swabs cut into two.
These often break during shipment so I am cutting them into halves.
5. NLGI 0/1 plastic grease for plastic gears for tray underneath.
WARNING.
1. ALWAYS WORK WITH DISCONNECTED POWER. THERE IS LIVE POWER!!!
2. NEVER LOOK DIRECTLY AT THE LASER. YOU WILL DAMAGE YOUR EYES.
3. GROUND YOURSELF TO DISCHARGE ANY STATIC IN YOUR BODY.
The basic procedure to belt replacement is below. See attached picture from the
service manual
of DCD-1520 which is very similar to all models listed above.
1. Open the tray and remove disc
2. Turn power off and pull the plug
3. Remove black TOP COVER by remove the four side screws. Some units have one
screw in the rear center.
4. Remove galvanized INSIDE BOTTOM COVER
5. Place the cd player vertically on its side. Remove front FRONT PANEL by
removing all screws
and then slightly pressing with a small screwdriver on all six hooks. These are
plastic locking clicks that
hold the face panel. Do not over press these as you will break them. I have
broken a few in the past. Just
press enough to release pressure. There is a grounding wire connectic front
panel to chassis. You can
pull wire from its connection on the front panel. Set aside front panel
6. Now you can see the top tray belt just below the tray (BELT A). I call this
belt long skinny. You can
also see the lower belt B, I call it fat short (BELT B).
7. Remove one belt at a time and clean the grooves of the pulley with cotton
swab and some alcohol.
If you have big hands, you may need tweezers or help with a screwdriver.
8. Clean all previous grease under the tray gears with paper towel and alcohol.
Then apply this crease
with a small flat screwdriver. You can apply in other areas of the tray
mechanism where plastic to
plastic parts come in contact. See picture with areas boxed in RED.
9. Left side of tray, there is a 5mm metal rod for tray mechanism. Clean and
lubricate with Tri-Flow oil.
Do not over lubricate, a thin coat is plenty good
10. Now clean the 2.5mm metal rod that laser moving mechanism slides. Carefully
clean and lube.
DO NOT over lubricate.
11. Connect power and turn on. Eject tray and close. If the tray gets stuck or
sluggish or not closing
all the way, then, one ore more things can be going on. Belt(s) slipping due to
debris or oil. Clean.
Also areas boxed in red and tray gears under tray could overlubed. Wipe away
some grease.
12 Test again. If all working assemble back together.
=====================================
Regards to modifications.
When you open the INSIDE BOTTOM COVER, you have seen the PCB on the right side
where the DAC Digital To Analog Conversion is done. There are many chips for
this function
including the DAC chips, series of OPAMPs and a bunch of capacitors. Replacing
these opamps
and capacitors you can extensively improve the sound of these cd players.
I have upgraded other cd players such as
Yamaha CDX-1100U
and up, Nakamichi OMS-5 and up, Sony high end CD and SACD players, California
Audio
Labs cd players. I have several levels of upgrade and cheapest LEVEL 0 is where
you remove
the PCB board and I replace all the components and you assemble back. With MOD
LEVEL 3
modification, you can the entire unit and I spend about 6 hours cleaning,
upgrading your cd player.
I use the absolute best components such as super duper opamps Texas
Instrument's
Burr-Brown OPA-627. These are the quietest and best opamps only used in the
$5000 and up cd/sacd player such as Wadia, Esoteric, and other fancy units.
There are different levels of this mod. I will put MODs 0, 1,2 and 3.
MOD 0
It's essentially MOD2 but you send me the PCB board and replace the opamps and capacitors. Cheapest and
most bang for your buck.
If available, I can send you a modified board and you send me yours.
MOD1
No longer available
MOD 2
1. Replace the power filter capacitor and most capacitors in the DAC area
(larger than 1/4" diameter) audiphile grade
capacitors including Elna, some of them are Panasonic or Nichicons due to size limitations.
2. Replace all opamps with audiophile grade Burr-Brown after the DAC
3. Replace belt A and B with factory new ones
4. Relube the tray mechanism with NLGI grease for metal/plastic
5. Relube delicare areas with Teflon based oil
6. Clean all RCA jacks and headphone jack and volume pot with Deoxit (contact
cleaner)
7. Burn in for 12 hours for all the components.
8. Clean inside and outside
9. Copy of service manual
10. UPS shipping back to you with delivery confirmation and insurance
MOD3
1. Same as MOD2 but use Burr-Brown OPA-627 super duper opamps
