CHANGES IN COURSE OF PRODUCTION
In course of production the 3 disc changer module 3CDC-LC has been introduced as an alternative.
*
Compared to the original used 3CDC-LC-MB there are different servo / motor driver ICs (TDA7073A) used on the CD board.
The new board can be identified by the 12 fig. number 3103 303 34255 printed in the copper pattern.
Note: New chapter 3CDC-LC is enclosed to this Service Information.
From production week 0148 to 0152 a different changer module 3CDC99-DS has been used.
*
This module can be identified by:
- The tray is not locked and can be opened by simply pulling it out.
- The 12 fig. number printed on the 3CDC99-DS board reads 3103 303 34283.
To enable the use of this 3CDC99-DS version following modifications have been implemented:
Mechanical:
Pos. 107 changed to 8203 306 84031 Cover Tray 3CDC99
Front Board:
7401 changed to 8203 239 35241 TMP87CP71F
Note: This microprocessor will only work in combination with the 3CDC99 Module.
Combi Board:
1509 Flex Foil Socket 15p deleted
1511 Flex Foil Socket 23p (4822 267 10757) added. Pin 20-23 have been removed in order to adapt the socket to the layout
of the Combi Board.
3574 and 3575 changed to 33kΩ (4822 051 20333)
3576 and 3577 changed to 5,6kΩ (4822 051 20562)
Note: The complete chapter 3CDC99-DS is enclosed to this Service Information.
