The service procedures recommended by Philips and described in this service manual are effective methods of performing service operations. Some of these service special tools should be used when and as recommended.It is important to note that this service 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 advice 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 use all precautions thoroughly so that neither his safety nor the safe operation of the equipment will be jeopardized by the service method selected.TABLE OF CONTENTSLASER BEAM SAFETY PRECAUTIONS . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-1-1IMPORTANT SAFETY PRECAUTIONS. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-2-1STANDARD NOTES FOR SERVICING . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-3-1OPERATING CONTROLS AND FUNCTIONS. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-4-1SIGNAL NAME ABBREVIATIONS . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-5-1CABINET DISASSEMBLY INSTRUCTIONS . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-6-1HOW TO INITIALIZE THE BLU-RAY DISC PLAYER . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-7-1FIRMWARE RENEWAL MODE . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-8-1TROUBLESHOOTING . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-9-1BLOCK DIAGRAMS. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-10-1SCHEMATIC DIAGRAMS / CBAS. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-11-1WAVEFORMS . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-12-1WIRING DIAGRAM . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-13-1SYSTEM CONTROL TIMING CHARTS. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-14-1IC PIN FUNCTION DESCRIPTIONS. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-15-1LEAD IDENTIFICATIONS . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-16-1ELECTRICAL PARTS LIST . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-17-1EXPLODED VIEWS. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-18-1MECHANICAL PARTS LIST . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-19-1Manufactured under license from Dolby Laboratories.

When checking the laser diode, be sure to keep your eyes at least 30 cm away from the pickup lens when the diode is turned on. Do not look directly at the laser beam.CAUTION: Use of controls and adjustments, or doing procedures other than those specified herein, may result in hazardous radiation exposure.Location: Inside Top of BD mechanism.Do not look directly at the laser beam coming from the pickup or allow it to strike against your skin.Drive Mechanism AssemblyLaser Beam RadiationLaser PickupTurntable1-2-1 BDP_ISPIMPORTANT SAFETY PRECAUTIONSProduct Safety NoticeSome electrical and mechanical parts have specialsafety-related characteristics which are often not evi-dent from visual inspection, nor can the protectionthey give necessarily be obtained by replacing themwith components rated for higher voltage, wattage,etc. Parts that have special safety characteristics areidentified by a ! on schematics and in parts lists. Useof a substitute replacement that does not have thesame safety characteristics as the recommendedreplacement part might create shock, fire, and/or otherhazards. The Products Safety is under review continu-ously and new instructions are issued wheneverappropriate. Prior to shipment from the factory, ourproducts are carefully inspected to confirm with therecognized product safety and electrical codes of thecountries in which they are to be sold. However, inorder to maintain such compliance, it is equally impor-tant to implement the following precautions when a setis being serviced.Precautions during ServicingA. Parts identified by the ! symbol are critical forsafety. Replace only with part number specified.B. In addition to safety, other parts and assembliesare specified for conformance with regulationsapplying to spurious radiation. These must also bereplaced only with specified replacements.Examples: RF converters, RF cables, noise block-ing capacitors, and noise blocking filters, etc.C. Use specified internal wiring. Note especially:1)Wires covered with PVC tubing2)Double insulated wires3)High voltage leadsD. Use specified insulating materials for hazardouslive parts. Note especially:1)Insulation tape2)PVC tubing 3)Spacers4)Insulators for transistorsE. When replacing AC primary side components(transformers, power cord, etc.), wrap ends ofwires securely about the terminals before solder-ing.F. Observe that the wires do not contact heat produc-ing parts (heatsinks, oxide metal film resistors, fus-ible resistors, etc.).G. Check that replaced wires do not contact sharpedges or pointed parts.H. When a power cord has been replaced, check that5 - 6 kg of force in any direction will not loosen it.I. Also check areas surrounding repaired locations.J. Use care that foreign objects (screws, solder drop-lets, etc.) do not remain inside the set.K. When connecting or disconnecting the internalconnectors, first, disconnect the AC plug from theAC outlet.1-2-2 BDP_ISPSafety Check after ServicingExamine the area surrounding the repaired locationfor damage or deterioration. Observe that screws,parts, and wires have been returned to their originalpositions. Afterwards, do the following tests and con-firm the specified values to verify compliance withsafety standards.1. Clearance DistanceWhen replacing primary circuit components, confirmspecified clearance distance (d) and (d) between sol-dered terminals, and between terminals and surround-ing metallic parts. (See Fig. 1)Table 1 : Ratings for selected areaNote: This table is unofficial and for reference only. Be sure to confirm the precise values.2. Leakage Current TestConfirm the specified (or lower) leakage currentbetween B (earth ground, power cord plug prongs)and externally exposed accessible parts (RF termi-nals, antenna terminals, video and audio input andoutput terminals, microphone jacks, earphone jacks,etc.) is lower than or equal to the specified value in thetable below. Measuring Method (Power ON) :Insert load Z between B (earth ground, power cordplug prongs) and exposed accessible parts. Use anAC voltmeter to measure across the terminals of loadZ.

For other ICs, pin 1 and every fifth pin are indicated as shown.3. The 1st pin of every male connector is indicated as shown.Instructions for Connectors1. When you connect or disconnect the FFC (Flexible Foil Connector) cable, be sure to first disconnect the AC cord.2. FFC (Flexible Foil Connector) cable should be inserted parallel into the connector, not at an angle.Pb (Lead) Free SolderWhen soldering, be sure to use the Pb free solder.Information about lead-free solderingPhilips CE is producing lead-free sets from 1.1.2005 onwards. IDENTIFICATIONRegardless of special logo (not always indicated) One must treat all sets from onwards, according to the next rule:Serial Number gives a 14-digit. Digit 5 when removing entire flat pack-IC, first apply soldering iron to center of the flat pack-IC and heat up. Then remove (glue will be melted). (Fig. S-1-6)4. Release the flat pack-IC from the CBA using tweezers. (Fig. S-1-6)CAUTION:1. The Flat Pack-IC shape may differ by models. Use an appropriate hot-air flat pack-IC desoldering machine, whose shape matches that of the Flat Pack-IC.2. Do not supply hot air to the chip parts around the flat pack-IC for over 6 seconds because damage to the chip parts may occur. Put masking tape around the flat pack-IC to protect other parts from damage. (Fig. S-1-2)Fig. S-1-11-3-3 B1N_PC_SN3. The flat pack-IC on the CBA is affixed with glue, so be careful not to break or damage the foil of each pin or the solder lands under the IC when removing it.With Soldering Iron:1. Using desoldering braid, remove the solder from all pins of the flat pack-IC. When you use solder flux which is applied to all pins of the flat pack-IC, you can remove it easily. (Fig. S-1-3)2. Lift each lead of the flat pack-IC upward one by one, using a sharp pin or wire to which solder will not adhere (iron wire). When heating the pins, use a fine tip soldering iron or a hot air desoldering machine. (Fig. S-1-4)3. Bottom of the flat pack-IC is fixed with glue to the CBA; when removing entire flat pack-IC, first apply soldering iron to center of the flat pack-IC and heat up. Then remove (glue will be melted). (Fig. S-1-6)4. Release the flat pack-IC from the CBA using tweezers. (Fig. S-1-6)With Iron Wire:1. Using desoldering braid, remove the solder from all pins of the flat pack-IC. When you use solder flux which is applied to all pins of the flat pack-IC, you can remove it easily. (Fig. S-1-3)2. Affix the wire to a workbench or solid mounting point, as shown in Fig. S-1-5.3. While heating the pins using a fine tip soldering iron or hot air blower, pull up the wire as the solder melts so as to lift the IC leads from the CBA contact pads as shown in Fig. S-1-5.4. Bottom of the flat pack-IC is fixed with glue to the CBA; when removing entire flat pack-IC, first apply soldering iron to center of the flat pack-IC and heat up. Then remove (glue will be melted). (Fig. S-1-6)5. Release the flat pack-IC from the CBA using tweezers. (Fig. S-1-6)Note: When using a soldering iron, care must be taken to ensure that the flat pack-IC is not being held by glue. When the flat pack-IC is removed from the CBA, handle it gently because it may be damaged if force is applied.Hot-airFlat Pack-ICDesolderingMachineCBAFlat Pack-ICTweezersMasking TapeFig. S-1-2Flat Pack-ICDesoldering BraidSoldering IronFig. S-1-3Fine TipSoldering IronSharpPinFig. S-1-4To Solid Mounting PointSoldering IronIron WireorHot Air BlowerFig. S-1-5Fine TipSoldering IronCBAFlat Pack-ICTweezersFig. S-1-61-3-4 B1N_PC_SN2. Installation1. Using desoldering braid, remove the solder from the foil of each pin of the flat pack-IC on the CBA so you can install a replacement flat pack-IC more easily.2. The “” mark on the flat pack-IC indicates pin 1. (See Fig. S-1-7.) Be sure this mark matches the 1 on the PCB when positioning for installation. Then presolder the four corners of the flat pack-IC. (See Fig. S-1-8.)3. Solder all pins of the flat pack-IC. Be sure that none of the pins have solder bridges.Instructions for Handling Semi-conductorsElectrostatic breakdown of the semi-conductors may occur due to a potential difference caused by electrostatic charge during unpacking or repair work.1. Ground for Human BodyBe sure to wear a grounding band (1 M) that is properly grounded to remove any static electricity that may be charged on the body.2. Ground for WorkbenchBe sure to place a conductive sheet or copper plate with proper grounding (1 M) on the workbench or other surface, where the semi-conductors are to be placed. Because the static electricity charge on clothing will not escape through the body grounding band, be careful to avoid contacting semi-conductors with your clothing.Example :Pin 1 of the Flat Pack-ICis indicated by a “ “ mark.Fig. S-1-7PresolderCBAFlat Pack-ICFig. S-1-8CBAGrounding BandConductive Sheet orCopper Plate1M1MCBA1-4-1 E5J10IBOPERATING CONTROLS AND FUNCTIONS
