Philips FW C220 SI Service Manual

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.

3CDC-LC

(3 Disc Carousel Changer)

Layout stage .5

10-2

The following steps have to be done when replacing the CD mechanism:

1. Disconnect flexfoil cable from the old CD drive

2. Put a paperclip on the flexfoil to short-circuit the contacts (fig.1)

3. Remove the old CD drive

4. Remove paperclip from the flexfoil and connect it to the new drive

5. Position the new CD drive in its studs

6. Remove solder joint from the Laserunit

CHARGED CAPACITORS ON THE SERVO BOARD MAY DAMAGE THE CD DRIVE ELECTRONICS WHEN
CONNECTING A NEW CD MECHANISM. THAT´S WHY, BESIDES THE SAFETY MEASURES LIKE

• SWITCH OFF POWER SUPPLY

• ESD PROTECTION
ADDITIONAL ACTIONS MUST BE TAKEN BY THE REPAIR TECHNICIAN.

fig.1

Attention: The laser diode of this CD drive is protected against ESD by a solder joint which shortcircuits the

laserdiode to ground.
For proper functionality of the CD drive this solder joint must be removed after connection the drive to
the set.

Emergency open

Service hints

In case of a Supply fault, the tray can be opened manually.

1. Remove the top cover of the set to get access to the Changer Module.

2. Turn gearwheel clockwise (as shown in picture below).
