FW595C, FW748P, FW768P, FW798W
SYMPTOM :
Digital hum (whistling tone) is audible from the display in quiet environment.
CURE : The source of the noise comes from the filtering SMD capacitors
2483 - 2486 for the FTD display supply -F1 and -F2. The problem is resolved by adding 2 x 2 elcaps of 4,7µF (4822 124 40769) in series across the existing SMDs capacitors. The capacitors can by soldered onto the copperside of the Front board as indicated in the circuit and SMD layout view below.
Rework procedure:
1) Dismantle the Rear Cover, Cover CDC & CDC Module.
2) Prepare 2 sets of 2 x 4,7µF elcaps (4822 124 40769) in series.
3) Place an insulation tape onto the Front board (area under the elcaps) to prevent the elcaps and their leads from short-circuiting to the surrounding SMD components and pads.
4) Position the elcaps horizontally over the insulation tape and solder them to the copper pads as shown. Make sure that the elcaps are close to the Front board so that there is no contact to the moving parts of the CDC module.
5) Re-assemble the CDC Module, Cover CDC and Rear Cover.

REMARKS :
01.05 TYPENUMBER(S): FW680V INFORMATION : Correction to Service Manual, Electrical par tslist page 6-6
Codenumber for the microprocessor pos.7401 should read: 4822 209 13243 microprocessor not for /22 4822 209 13242 microrpocessor only for /22
REMARKS :
01.06 TYPENUMBER(S): FW830C, FW840C, FW870C, FW878C, FW890P, FW898W INFORMATION : The following resistor has been changed on the front board to
improve the data reliability to the EEPROM: 3596 4822 117 12521 68Ω 1% 0,1W
REMARKS :
01.07 TYPENUMBER(S): FW830C, FW840C, FW870C, FW878C, FW890P, FW898W
SYMPTOM :
CD does not play and the display shows “DISC NOT FINALIZED”.
CURE : The problem happens mainly with Brazil’s Millennium disc and is
resolved by upgrading the software of the Front microprocessor IC (pos. 7413) to version 20. The service code for the new IC reads 9965 000 02901.
