IMPORTANT SAFETY NOTICE

Proper service and repair is important to the safe, reliable operation of all Philips Consumer Electronics Company** Equipment. The service procedures recommended by Philips and described in this service manual are effective methods of performing service operations. Some of these service operations require the use of tools specially designed for the purpose. The special tools should be used when and as recommended.

It is important to note that this manual contains various CAUTIONS and NOTICES which should be carefully read in order to minimize the risk of personal injury to service personnel. The possibility exists that improper service methods may damage the equipment. It also is important to understand that these CAUTIONS and NOTICES ARE NOT EXHAUSTIVE. Philips could not possibly know, evaluate and advise the service trade of all conceivable ways in which service might be done or of the possible hazardous consequences of each way. Consequently, Philips has not undertaken any such broad evaluation. Accordingly, a servicer who uses a service procedure or tool which is not recommended by Philips must first satisfy himself thoroughly that neither his safety nor the safe operation of the equipment will be jeopardized by the service method selected.

** Hereafter throughout this manual, Philips Consumer Electronics Company

will be referred to as Philips.

WARNING

Critical components having special safety characteristics are identified with a # by the Ref. No. in the parts list and enclosed within a broken line* (where several critical components are grouped in one area) along with the safety symbol # on the schematics or exploded views.

Use of substitute replacement parts which do not have the same specified safety characteristics may create shock, fire, or other hazards.

Under no circumstances should the original design be modified or altered without written permission from Philips. Philips assumes no liability, express or implied, arising out of any unauthorized modification of design. Servicer assumes all liability.

1. Disconnect the following: Anode Cap, CN501, CRT CBA, CN571, CN2602, and CN1301. Then remove H.V. CBA (with Holder).

CAUTION 2: Electrostatic breakdown of the laser diode in the optical system block may occur as a potential difference caused by electrostatic charge accumulated on cloth, human body etc., during unpacking or repair work.

To avoid damage of pickup follow these procedures. 2-1. Short the three short lands of FPC cable with sol-

der before removing the FFC cable (CN201) from it. If you disconnect the FFC cable (CN201), the laser diode of pickup will be destroyed. (Fig. 4)

S-1

2-2. Disconnect connector (CN301). Remove two

screws (S-7) and lift the DVD Main CBA Unit. (Fig. 4)

CAUTION 3: When reassembling, confirm the FFC cable (CN201) is connected completely. Then remove the solder from the three short lands of FPC cable. (Fig. 4)

4. Remove screws 7(S-10), 1(S-11), and 1(S-12). Then, desolder connectors (CL1201, C1401, CL1402, CL1403) and lift up the Deck Assembly.

WARNING

Critical components having special safety characteristics are identified with a # by the Ref. No. in the parts list and enclosed within a broken line* (where several critical components are grouped in one area) along with the safety symbol # on the schematics or exploded views. Use of substitute replacement parts which do not have the same specified safety characteristics may create shock, fire or other hazards. Under no circumstances should the original design be modified or altered without written permission from Philips Consumer Electronics Company. Philips assumes no liability, express or implied, arising out of any unauthorized modification of design. Servicer assumes all liability. * Broken Line :

Notes:

1. Do not use the part number shown on these drawings for ordering. The correct part number is shown in the parts list, and may be slightly different or amended since these drawings were prepared.

2. To maintain original function and reliability of repaired units, use only original replacement parts which are listed with their part numbers in the parts list section of the service manual.

3. Prefix symbol "CN" means "connector" (can disconnect and reconnect). Prefix symbol "CL" means "wire-solder holes of the PCB" (wire is soldered directly).

4. How to read converged lines.

1-D3

Distinction Area Line Number (1 to 3 digits)

Examples: (1). "1-D3" means that line number "1" goes to area

"D3."

(2). "1-B1" means that line number "1" goes to area

"B1."

5. All resistance values are indicated in ohms

3

(K=10

, M=106).

6. Resistor wattages are 1/4W or 1/6W unless otherwise specified.

7. All capacitance values are indicated in µF

-6

(P=10

µF).

8. All voltages are DC voltages unless otherwise specified.

9. Voltage indications for PLAY and REC modes on the schematics are as shown below
