ORIGINAL MFR'S VERSION A
Design and specifications are subject to change without notice.
IMPORTANT WARNING
CAUTION: DVD PLAYER IS A CLASS 1 LASER PRODUCT. HOWEVER THIS PLAYER USES A VISIBLE LASER BEAM WHICH COULD CAUSE HAZARDOUS RADIATION EXPOSURE IF DIRECTED. BE SURE TO OPERATE THE PLAYER CORRECTLY AS INSTRUCTED. THE FOLLOWING CAUTION LABEL IS LOCATED ON THE REAR PANEL OF THE PLAYER.
CLASS 1 LASER PRODUCT
(Printed on the Rear Panel)
WHEN THIS PLAYER IS PLUGGED TO THE WALL OUTLET, DO NOT PLACE YOUR EYES CLOSE TO THE OPENING OF THE DISC TRAY AND OTHER OPENINGS TO LOOK INTO THE INSIDE OF THIS PLAYER. USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE. DO NOT OPEN COVERS AND DO NOT REPAIR YOURSELF. REFER SERVICING TO QUALIFIED PERSONNEL.
SERVICING NOTICES ON CHECKING
1. KEEP THE NOTICES
As for the places which need special attentions, they are indicated with the labels or seals on the cabinet, chassis and parts. Make sure to keep the indications and notices in the operation manual.
3. PUT PARTS AND WIRES IN THE ORIGINAL POSITION AFTER ASSEMBLING OR WIRING
There are parts which use the insulation material such as a tube or tape for safety, or which are assembled in the condition that these do not contact with the printed board. The inside wiring is designed not to get closer to the pyrogenic parts and high voltage parts. Therefore, put these parts in the original positions.
2. USE THE DESIGNATED PARTS
The parts in this equipment have the specific characters of incombustibility and withstand voltage for safety. Therefore, the part which is replaced should be used the part which has the same character. Especially as to the important parts for safety which is indicated in the circuit diagram or the table of parts as a mark, the designated parts must be used.
4. PERFORM A SAFETY CHECK AFTER SERVICING
Confirm that the screws, parts and wiring which were removed in order to service are put in the original positions, or whether there are the portions which are deteriorated around the serviced places serviced or not. Check the insulation between the antenna terminal or external metal and the AC cord plug blades. And be sure the safety of that.
HOW TO ORDER PARTS
Please include the following informations when you order parts. (Particularly the VERSION LETTER.) 1. MODEL NUMBER and VERSION LETTER The MODEL NUMBER can be found on the back of each product and the VERSION LETTER can be found at the end of the SERIAL NUMBER. 2.

3. REMOVAL OF ANODE CAP
Read the following NOTED items before starting work. * After turning the power off there might still be a potential voltage that is very dangerous. When removing the Anode Cap, make sure to discharge the Anode Cap's potential voltage. * Do not use pliers to loosen or tighten the Anode Cap terminal, this may cause the spring to be damaged. REMOVAL 1. Follow the steps as follows to discharge the Anode Cap. (Refer to Fig. 3-1.) Connect one end of an Alligator Clip to the metal part of a flat-blade screwdriver and the other end to ground. While holding the plastic part of the insulated Screwdriver, touch the support of the Anode with the tip of the Screwdriver. A cracking noise will be heard as the voltage is discharged. 3. After one side is removed, pull in the opposite direction to remove the other. NOTE Take care not to damage the Rubber Cap. INSTALLATION 1. Clean the spot where the cap was located with a small amount of alcohol. (Refer to Fig. 3-3.) NOTE Confirm that there is no dirt, dust, etc. at the spot where the cap was located.

4. REMOVAL AND INSTALLATION OF FLAT PACKAGE IC
REMOVAL 1. Put the Masking Tape (cotton tape) around the Flat Package IC to protect other parts from any damage. (Refer to Fig. 4-1.) NOTE Masking is carried out on all the parts located within 10 mm distance from IC leads.
Blower type IC desoldering machine
3. When IC starts moving back and forth easily after desoldering completely, pickup the corner of the IC using a tweezers and remove the IC by moving with the IC desoldering machine. (Refer to Fig. 4-3.) NOTE Some ICs on the PCB are affixed with glue, so be careful not to break or damage the foil of each IC leads or solder lands under the IC when removing it.

2. Heat the IC leads using a blower type IC desoldering machine. (Refer to Fig. 4-2.) NOTE Do not add the rotating and the back and forth directions force on the IC, until IC can move back and forth easily after desoldering the IC leads completely. 4. Peel off the Masking Tape.
Fig. 4-3
5. Absorb the solder left on the pattern using the Braided Shield Wire. (Refer to Fig. 4-4.) NOTE Do not move the Braided Shield Wire in the vertical direction towards the IC pattern.

DISASSEMBLY INSTRUCTIONS
INSTALLATION 1. Take care of the polarity of new IC and then install the new IC fitting on the printed circuit pattern. Then solder each lead on the diagonal positions of IC temporarily. (Refer to Fig. 4-5.) 4. When bridge-soldering between terminals and/or the soldering amount are not enough, resolder using a Thin-tip Soldering Iron. (Refer to Fig. 4-8.)

Confirm that no abnormality is found on the soldering position and installation position of the parts around the IC. If some abnormality is found, correct by resoldering. NOTE When the IC leads are bent during soldering and/or repairing, do not repair the bending of leads. If the bending of leads are repaired, the pattern may be damaged. So, be always sure to replace the IC in this case.

ELECTRICAL ADJUSTMENTS
1. BEFORE MAKING ELECTRICAL ADJUSTMENTS
Read and perform these adjustments when repairing the circuits or replacing electrical parts or PCB assemblies. CAUTION · Use an isolation transformer when performing any service on this chassis. · Before removing the anode cap, discharge electricity because it contains high voltage. · When removing a PCB or related component, after unfastening or changing a wire, be sure to put the wire back in its original position. · When you exchange IC and Transistor for a heat sink, apply the silicon grease (YG6260M) on the contract section of the heat sink, Before applying new silicon grease, remove all the old silicon grease. (Old grease may cause damages to the IC and Transistor.) Prepare the following measurement tools for electrical adjustments. 1. Oscilloscope 2. Digital Voltmeter 3. AC Voltmeter 4. Pattern Generator 5. Multi-Sound Signal Generator On-Screen Display Adjustment 1. Set the VOLUME to minimum. 2. Press the VOL. DOWN button on the set and the Channel button (9) on the remote control for more than 1 second to appear the adjustment mode on the screen as shown in Fig. 1-1 .

NOTE 1. Turn the unit on and let it warm up for at least 30 minutes before performing the following adjustments. 2. Place the CRT surface facing east or west to reduce the terrestrial magnetism. 3. Turn ON the unit and demagnetize with a Degauss Coil. 3-1: STATIC CONVERGENCE (ROUGH ADJUSTMENT) 1. Tighten the screw for the magnet. Refer to the adjusted CRT for the position. (Refer to Fig. 3-1) If the deflection yoke and magnet are in one body, untighten the screw for the body. 2. Receive the green raster pattern from the color bar generator. 3. Slide the deflection yoke until it touches the funnel side of the CRT. 4. Adjust center of screen to green, with red and blue on the sides, using the pair of purity magnets. 5. Switch the color bar generator from the green raster pattern to the crosshatch pattern. 6. Combine red and blue of the 3 color crosshatch pattern on the center of the screen by adjusting the pair of 4 pole magnets. 7. Combine red/blue (magenta) and green by adjusting the pair of 6 pole magnets. 8. Adjust the crosshatch pattern to change to white by repeating steps 6 and 7. 3-2: PURITY NOTE Adjust after performing adjustments in section 3-1. 1. Receive the green raster pattern from color bar generator. 2. Adjust the pair of purity magnets to center the color on the screen. Adjust the pair of purity magnets so the color at the ends are equally wide. 3. Move the deflection yoke backward (to neck side) slowly, and stop it at the position when the whole screen is green. 4. Confirm red and blue colors. 5. Adjust the slant of the deflection yoke while watching the screen, then tighten the fixing screw.
