Default Sony X5000 troubleshooting

Hi
I understand the KSS 272A laser unit is -since a long time, not available anymore.
Anyone having succed finding any eqvivalent unit, or tracking/changing the diode successfully?

Please I need advise what action to take

Brgds

Either you have an other compact disc player model or an other laser unit - go to

and to the attachements

The KSS272A (= 884824411 = KSS-272A) is inside there:

pixworld, first look here:
Laserology

You may try that procedure - if you don't have success I think I can help you out (have a Sony CDP-X505ES which has excellent condition KSS 272A laser unit - I don't use this CDP any more since I have a CMP2 transport)

regards

Sorry, my misstake
It should be a X5000 player with a KSS-274A laser

This much more newer model (the newest from the KSS series used in ESPRIT players - as I know) is in the meantime also no longer available about the SONY repair service.
But various auctions you will find sometimes, e. g.

CD???????KSS-274A
?? ?? KSS-274A - ?? KS Audio ?????? ??? 010-2929-8432 - ??! ???
Kogerer - CD / scroll down
CD?????? KSS,KHM,KHS,CDM,VAM,OPTIMA,SF,H,KCP,TAOHS,? (No 27)

and a discussion regarded the suppliers
www.HiFi-Forumi.com • Pogledaj temu - Sony kss for Sony Es

However - KSS-272A is much more harder to find than the KSS-274A - so I think. Hardest to find are the models KSS-280A (only inside in CDP-X77ES) and KSS-281A (only inside in CDP-X777ES).

I want to replace the laser diode itself by all no longer KSS models. Therefore I have start various threads here to get more informations about data sheets and replacement parts for the used laser diodes - unfortunately without success until this day:
Laser Diode Successor of SLD-104U for SONY ESPRIT KSS Series
Databook about SONY's KSS optical pick up series

Here is some info on the cdp x5000 taken from the service manual. It is about calibrating the laser output utilizing a special service disc: SECTION 1
SERVICING NOTE
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic
break-down because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-down and also use
the procedure in the printed matter which is included in the repair
parts.
The flexible board is easily damaged and should be handled with
care.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused on
the disc reflective surface by the objective lens in the optical pick-up
block. Therefore, when checking the laser diode emission, observe
from more than 30 cm away from the objective lens.
LASER DIODE AND FOCUS SEARCH OPERATION CHECK
Carry out the “S curve check” in “CD section adjustment” and check
that the S curve waveform is output three times.
WRITING OF FOCUS/TRACKING AUTO GAIN DATA
General CD palyers using digital servo ICs automatically adjust the
focus/tracking gain each time the disc is changed.
In this unit, the gain of the standard disc (YEDS-18) is written in the
non-volatile memory (IC203:X24C01S) of the servo board so that
the gain need not be re-adjusted when changing discs.
Therefore, if the servo board, IC203 of the servo board, or optical
pick-up has been replaced, be sure to write the auto gain data.
1. Connect TP (ADJ: Pin 3 of CN515) to GND (Ground), and turn
ON the POWER switch.
2. Insert the test disc (YEDS-18). (The TOC data of the disc will be
read.)
This memorizes the auto gain data of the test disc.
Note:
• If the disc is replaced without turning OFF the power, the auto gain
data of the last disc inserted will be memorized.
• If the POWER switch is turned ON without connecting TP (ADJ)
to GND, the auto gain data will not be memorized when the disc is
inserted, and the data memorized the last time will be taken as the
focus/tracking data.
FLUORESCENT INDICATOR TUBE FULL LIGHTING MODE
1. Connect TP (AFJ:Pin 2 of CN515) to GND (Ground), and turn
ON the POWER switch.
2. The bridge check (check for short-circut between pins of the S
RAM (IC202 of the servo board)) is performed, and all the FL
tubes light up if there is no bridge.
3. When a key other than the p(stop) key is pressed, the corresponding
FL tubes lights up.
Each time the p(stop) key is pressed, all the FL tubes light up.
[SERVO BOARD] — Conductor Side —

Well, received the SONY cdp-x5000 player today from Singapore. After cleaning and removing dust and changing the small switches on the keyboard printed circuit board (probably corrosion, high humidity in Singapore) I cannot make it to fail on reading the disk. It works absolutely perfect. If you have problems reading the disc I would recommend the procedure mentioned earlier. If you open the top cover of the player (careful with the cabling) you will see three plugs with no connection on them in front of the drive. CN513 CN514 and CN515. Unless you are used to handling a soldering iron I would advice to find a plug that fits in the three pin CN515. Solder pin 1 and 3 together on the plug or put in an on/off switch for future use. (very handy). Turn off the power. Put in the plug or press the mounted switch. Insert the YEDS-18 and read the Table Of Content (TOC). Turn off the power. Remove the plug or turn switch off. The data has been saved in the small chip you see connected to pin 19 and 20 on controller IC201. One line is the clock an the other is data. I suspect this would calibrate the laser for mechanical wear/aging ?. I also suspect that the TOC of any CD would bee sufficient for this procedure but of that I am not certain. GOOD LUCK. I will post any information here that comes to my knowledge that would be of interest

Well the cdp-x5000 has started to skip when it is cold. During this cold winter i have had this problem repeatedly when the player is cold. When the player has been turned on for half an hour or so the skipping stops. I have reason to believe that it is the lubrication of the sledge carrying the cd/spindle motor that has dried up over time or that the electrolytic capacitors on the power supply feeding the sledge motor. (may be ripple on the voltage caused by dried out capacitors ?) I will take it apart and report back information of interest. Absolutely a wonderful player by the way.

Absolutely no ripple on the voltage feeding the sledge motor. Tried two very very tiny drops of a very sticky bicycle chain oil on the sledge guide. That cured the problem. My advice is: Try to find the right lubrication/grease. This player need a different damping of the movement of the sledge, because of the weight of the sledge plus the spindle motor. The friction here is crucial for the correct function of the player. Good luck.

Hello Dacen,
is the skipping problem cured until today? I have the very same problem, not very audible, because error interpolation does a good job here.
I used some grease (Judy Butter, for lubricating bike forks or bearings) years ago. I do not know, wether the problem existed before, because I found out maybe 2 or three years after buying in 1997.
Also the CDP X5000 does sometimes not start, when the lid is closed. This problen was from the very beginning
Replaced the lid switch, but only with little improvement.

All the best,
Salar
