Hallo techneuten.

Ik heb hier sinds 2 jaar een Sony SCD-XB940 staan en heb daar altijd veel plezier aan beleeft. De cd-speler was altijd al kieskeurig, op een paar cd's sloeg ie altijd 1 of 2 keer over en zelfs calibreren lukte niet op die cd's, hij gaf dan

Bedankt voor de reactie RastaPhil.

in de hele machine niets te vinden waar ik m'n gretige schroevendraaier in kan steken. Mischien moet ik eerst printplaten verwijderen en zit er dan wat wat aan de onderkant gaan maar dat ga me op dit moment te ver.

Het kan ook nog zo zijn dat alles menugestuurd is, ik heb ook wel eens opnieuw gecallibreerd dmv een menu, stond op Audio Asylum

 

The official procedure requires unobtianium test CDs, but I?ve found you don?t need them to get the job done. What you?ll need at hand is:

1/ A single layer SACD?I use any of the early SONY remasters that come in the grey paper sleeve.
2/ A regular CD?It?s best to use an older one, some new ones may have some copy protection BS that messes things up.
3/ A hybrid SACD
4/ And if possible, a double layer SACD?more on that later.

Start with no disc in the tray and the machine OFF. 

1/ Put the 940 into Test Mode by doing these steps:
a/ HOLD down the AMS controller knob, 
b/ turn the machine ON
c/ and while keeping the AMS held down, PRESS the STOP button.
d/ Let go of everything.
The display will read ?Test Mode Menu? if you?ve done this right.

2/ ROTATE the AMS one click clockwise, 
?1. Auto Adjust? shows.

3/ PUSH the AMS
?Auto Adj Menu? shows.

4/ ROTATE the AMS two clicks clockwise, 
?1. SACD?SL? shows.

5/ PUSH the AMS, the tray opens, and
?Set SACD? SL 12? shows, so load in a single layer SACD.

6/ PUSH the AMS, tray closes, all sorts of things happen, tray opens.
?Remove Disc? shows.

7/ Remove the SACD and PUSH the AMS. The tray closes.
?1. SACD?SL? shows again?and the pure SACD step is done..

8/ ROTATE the AMS one click clockwise, 
?2. CD? shows.

9/ PUSH the AMS, the tray opens and
?Set CD 12? shows.
Load in a standard (non CDR) music CD. 

10/ PUSH the AMS, again the tray closes?and opens.
?Remove Disc? shows.

11/ Remove the CD and PUSH the AMS. The tray closes.
?2. CD? shows again?so the CD calibration step is done.

12/ ROTATE the AMS one click clockwise, 
?3. SACD?DL? shows.
This means it wants a double layer SACD, and I don?t know how to recognise them from markings on the disc itself or it?s packaging. But I read on HiRez Forum that the Hillary Hahn ?Brahms/Stravinsky Violin Concertos? (SONY SS89649) is a DL, and it is accepted by the 940 for this test. Using any other SACD I?ve tried here gives an error message.

9/ With this disc, or another known DL, repeat the steps as above. 
If you don?t have a DL disc, bypass this step by going to step 10.

10/ ROTATE the AMS one click clockwise, and
?4. HYBRID? shows. 

11/ PRESS the AMS and repeat the same procedure as above.

12/ When ?4. HYBRID? shows again, you are DONE!

 

Voor dit moment het lensje gereinigd, ik hoop dat ie het blijft doen.

Ik heb net ff de servicemanual doorgelezen, je kan echt de gekste dingen doen, zo kun je de jitter meten en de lade kunstmatig verouderen door 'm honderdduizenden keren automatisch open en dicht te laten gaan. :lol:

IK wil gewoon een plaatje draaien. :P
