03.09 TYPENUMBER(S): CDR570, CDR770, CDR930
SYMPTOM :
Stops during recording
Motor noise while recording CDR/W disc
CURE : Above problems can be solved by a hardware (1) and a software (2)
modification. Note that both changes must be implemented at the
same time.
1. Hardware modification at the topside of the main board
• Change item 2335 from 10nF to 47nF (3198 017 34730)
• Change item 3337 from 68kΩ to 56kΩ (4822 051 30563)
Portion of Main Board (top side) for location of 2335 / 3337
2. Software modification
• The software version of item 7208 at the topside (in socket) has to
be changed to version 91.80 or higher.
Programmed flash memory with version 91.80 can be ordered with
codenumber 3104 123 94850.
• The software version of item 7703 at the top side (soldered) has to
be changed to version R-1.34 or higher.
Programmed flash memory with version R-1.34 can be ordered with
codenumber 3104 123 85760.

Portion of Main board for location of flash memories 7208 / 7703
REMARKS : The status of the main-board can be identified by the board label.
For board label F and lower :change 2335/3337, replace 7208/7703
For board label G : change 3337, replace 7208/7703
For board label H : replace 7208/7703
For board label I : no changes necessary
03.10 TYPENUMBER(S): FW350C, FW396C, FW545C, FW548C, FW555C, FW585C, FW590C
SYMPTOM :
Skips tracks periodically or slide motor does not start-up at all.
CURE : In regions with high environmental pollution the problem might be
caused by erosion of the slide motor’s collector.
Erosion will permanently worsen the start-up behaviour of the slide
motor, up to an extent where the slide servo does not respond fast
enough to recover the track actuator from its outer position → tracks
will be skipped periodically.
Defective sets should be repaired as follows:
1. Replace CD-dr ive VAM2201 (4822 691 10772)
2. Increase the gain of the slide ser vo loop in order to increase the
start-up voltage at the slide motor (preventive action)
• Change resistor 3849 to 82kΩ 5% 1/6W (4822 116 52304)
• Change resistor 3850 to 5.6kΩ 5% 1/6W (4822 116 52289)

03.12 TYPENUMBER(S): FW748P, FW768P, FW798W, FW-P73, FW-P75, FW-P78
SYMPTOM :
DPL test tone is distorted (“motor-boating” & lower frequency).
CURE : The problem is caused by insufficient capacitor value at pin 1
(noise sequencer) of the DPL IC M62460FP.
It is solved by changing capacitor 2769 to 47µF 20% 25V
(4822 124 40433)
REMARKS :
03.13 TYPENUMBER(S): FW890P, FW898W
INFORMATION : Correction to Service Manual, Electrical Partslist page 11-12.
The article description of item 7930 should read:

REMARKS :
03.14 TYPENUMBER(S): MC136
INFORMATION : Correction to the Service Manual, Mechanical Partslist
The codenumber of the Control Panel (item 52) is wrong.
It should read 4822 426 10655.
REMARKS :
03.15 TYPENUMBER(S): MC165, MC175
SYMPTOM :
The CD Tray cannot be closed and the display shows “BLOCK”.
CURE : The gears of the CD loader are out of coupling because of external
force or physical block of the tray during sliding out.
If it cannot be resumed, the gears must be re-aligned as shown on
page 14-2 of Service Manual 4722 725 26195 resp. 4822 725 26213.
