08.05 TYPENUMBER(S): CDC775, CC3000, CC4000

SYMPTOM :

CDC Tray does not open, the spindle for the Gearwheel (pos 95) is
broken (see picture below).

CURE : For integral cost reasons it is advised to exchange the complete set.
REMARKS : Sets affected were produced before production week 0026.

08.06 TYPENUMBER(S): CDR570, CDR770, CDR775, CDR776, CDR785, CDR786, CDR930,

CDR950, CDR951, FW-R7, FW-R8

INFORMATION : For service purpose an extension flexfoil for the connection of CDR

mainboard connector 1000 to CD-drive has been taken on stock.It is
available with codenumber 3104 157 11510.

The extension flexfoil enables measurements on the top side of the
mainboard without disconnecting or damaging the flex-connection
from the mainboard. Please note that all important measuring points
are positioned on the bottom side of the mainboard.

REMARKS : Take care to remove the extension flexfoil before retur ning the set to

the customer.

08.07 TYPENUMBER(S): CDR775

SYMPTOM :

In dubbing mode, the first milliseconds of the track are not recorded.

CURE : New software version 3.6 for CD-mainboard.

Programmed IC 7202 (soldered) can be ordered with codenumber
3104 123 85630.

REMARKS : The built-in CD software version can be read out by the electrical

service diagnostics.This mode can be entered by holding
<PLAY/PAUSE> & <FFWD> keys depressed while switching power
on.

The new software has been implemented in production with factor y
change code VN05 from week 0037 onwards.

08.08 TYPENUMBERS : CDR570, CDR770, CDR771, CDR775, CDR776

SYMPTOM :

The set is switched to stand-by after power on.

CURE : The problem occurs only with the recently introduced new power

supply unit “PSU CDR3 ECONOMY”.
It can be fixed with the following modification:

• change item 3127 (current sense resistor) from 1.5Ω to 1Ω
(4822 116 80176)

• change item 6141 (zener diode) from 18V to 20V (4822 130 10656)

REMARKS : The above modification has been implemented in production from

week 0034 onwards.

08.09 TYPENUMBER(S): CDR785, CDR786, FW-R7, FW-R8

SYMPTOM :

Clock jitter in DASP-IC item 7701 on CDR Mainboard can result in
hang-up of the microprocessor.After Power off, Power on the set will
normally star t but the phenomenon might return again.

CURE : To solve this problem in running production and as service solution,

the power supply of D3V3 has been improved by adding a resistor of
27Ω (CRB 1/6W A PM5 and codenumber 4822 116 52188) between
“disconnected” pin 1 of item 7535 and ground (hole 2 of item 1701).

See part of the main board (top side view) for location of the resistor.

REMARKS : With release of the A9 version of CDR Mainboard this resistor is

implemented in printed board layout and mounted in production.

08.10 TYPENUMBER(S): CDR785, CDR786, FW-R7, FW-R8

SYMPTOM :

When source “AUX DIGITAL” is selected and no source is connected
or it is switched off, there is a burst of noise audible through the
speakers ever y 3 seconds. If a digital source is connected and
switched on, the noise disappears.

CURE : • change SMD resistor

3300 on Interface Board (CDR785, CDR786) resp.
3358 on Digital Switch Board (FW-R7, FW-R8)
to 6.8kΩ (4822 117 11507)

• add resistor 2721 (6.8kΩ 4822 117 11507) on the bottom side of
CDR Main Board → see picture below

REMARKS : This solution will also be implemented in production as a running

change.

08.11 TYPENUMBER(S): EXP101, EXP103
INFORMATION : Correction to the Instruction For Use

The description of chapter “Remote Control” is not clear.
The Remote Control AY3767 will work with EXP101 only.
It cannot be used with EXP103.

FW-C83, FW-C85, FW-C90, FW-C870, FW-M55, FW-P73, FW-P75,
FW-P78, FW-P88, FW-P880, FW-P900, FW-V55

SYMPTOM :

When a wireless heaphone (eg. SBC8320, SBCHC630, etc.) is
connected to the headphone socket, the headphone sound is
continuously interrupted.

CURE : The phenomenon is caused by a mis-match between the output

impedance of the heaphone amplifier (32Ω - 1kΩ) and the input
impedance of the wireless transmitter (10kΩ).
Due to the high input impedance of the transmitter the signal
becomes so high that the muting circuit is triggered.
The problem is solved by adding 2 resistors, 330Ω (4822 116 52219)
from the headphone switch pin 2 and 5 to common ground.
