The OSD can be switched between PAL and NTSC.The module has 6 analog video outputs in 4 format: CVBS, Y/C, and RGB (YUV). However, depending on the module configuration, not all output can be available at the same time.Table 1-6 1.4.2 Option Jumpers:J1, J2 & J3 hard select the required video output on Connector 1800. Alternatively, pre-determined Software setting, via slash option, is also possible. DAC's that are not in used should be turned off.Note: RGB and YUV component video signals shared the same lines. Therefore, the module is not able to output both RGB and YUV at the same time.Superimposed DC level : 1.2VOutput impedance : 75ohmSignal-to-noise ratio : better than 65dBVideo bandwidth : 8MHz (± 3dB) / 16MHz (± 3dB) for progressive scanCopy protection : CSS: Macrovision Version 7.1.L.1 for NTSC/PAL interlaced video outputs: Macrovision AGC 1.03 for 480P progressive scan video outputFunction SERVICEService mode LOW (or pulled to ground)Normal mode HIGH (or unconnected)Signal name Video formatCVBS_VID CVBSY_VID, C_VID Y/CR_VID (V) / G_VID (Y) / B_VID (U) RGB (YUV)Safety Instructions, Warnings, and Notes EN 5SD-5.31SL 2.2. Safety Instructions, Warnings, and Notes2.1 Safety Instructions2.1.1 General SafetySafety regulations require that during a repair:Connect the unit to the mains via an isolation transformer.Replace safety components, indicated by the symbol , only by components identical to the original ones. Any other component substitution (other than original type) may increase risk of fire or electrical shock hazard.Safety regulations require that after a repair, you must return the unit in its original condition. Pay, in particular, attention to the following points:Route the wires/cables correctly, and fix them with the mounted cable clamps.Check the insulation of the mains lead for external damage.Check the electrical DC resistance between the mains plug and the secondary side:1. Unplug the mains cord, and connect a wire between the two pins of the mains plug.2. Set the mains switch to the 'on' position (keep the mains cord unplugged!).3. Measure the resistance value between the mains plug and the front panel, controls, and chassis bottom. 4. Repair or correct unit when the resistance measurement is less than 1 M. 5. Verify this, before you return the unit to the customer/user (ref. UL-standard no. 1492).6. Switch the unit off, and remove the wire between the two pins of the mains plug.2.1.2 Laser SafetyThis unit employs a laser. Only qualified service personnel may remove the cover, or attempt to service this device (due to possible eye injury).Laser Device UnitType : Semiconductor laser GaAlAsWavelength : 650 nm (DVD): 780 nm (VCD/CD)Output Power : 20 mW (DVD+RW writing): 0.8 mW (DVD reading): 0.3 mW (VCD/CD reading)Beam divergence : 60 degreeFigure 2-1 Note: Use of controls or adjustments or performance of procedure other than those specified herein, may result in hazardous radiation exposure. Avoid direct exposure to beam.2.2 Warnings2.2.1 GeneralAll ICs and many other semiconductors are susceptible to electrostatic discharges (ESD, ). Careless handling during repair can reduce life drastically. Make sure that, during repair, you are at the same potential as the mass of the set by a wristband with resistance. Keep components and tools at this same potential. Available ESD protection equipment: Complete kit ESD3 (small tablemat, wristband, connection box, extension cable and earth cable) 4822 310 10671. Wristband tester 4822 344 13999.Be careful during measurements in the live voltage section. The primary side of the power supply (pos. 1005), including the heatsink, carries live mains voltage when you connect the player to the mains (even when the player is 'off'!). It is possible to touch copper tracks and/or components in this unshielded primary area, when you service the player. Service personnel must take precautions to prevent touching this area or components in this area. A 'lightning stroke' and a stripe-marked printing on the printed wiring board, indicate the primary side of the power supply.Never replace modules, or components, while the unit is on.2.2.2 LaserThe use of optical instruments with this product, will increase eye hazard.Only qualified service personnel may remove the cover or attempt to service this device, due to possible eye injury.Repair handling should take place as much as possible with a disc loaded inside the player.Text below is placed inside the unit, on the laser cover shield:Figure 2-2 2.2.3 NotesDolbyManufactered under licence from Dolby Laboratories. “Dolby”, “Pro Logic” and the double-D symbol are trademarks of Dolby Laboratories.

TOHEI SLOT-IN LoaderThe loader is a non-repairable unit and in case of failure, it has to be replaced with a new loader. When replacing with a new Slot-in loader, two solder joints have to be removed after connecting the OPU flex foil to the Monoboard. The solder joints which short circuits the laser diodes to ground are for protection against ESD. Refer to Figure “ESD solder joint“ for location of solder points.Figure 4-3 ESD solder jointMonoboardThe Monoboard has to be repaired down to components level. Repair handling of the Monoboard requires a workshop with sophisticated de-soldering tools.4.2.2 Change of Slash number settingThe software setting can be change according to the following procedure:1. Press PLAY 2. Enter the 8-digit code on the remote control.3. Press PLAY.4. The change should effect immediately with information indicated on TV screen.4.2.3 Software upgrade via Download discBoth the application and servo software can be flashed into the DVD player by means of a CD-ROM disc. The CD-ROM disc has to be made with a CD writer SW.Application software1. Insert the Upgrade disc into the player.2. The upgrading operation will start automatically.3. Once the upgrading process finishes, the player will automatically eject the disc.4. Remove the Upgrade disc.5. The player will be restarted automatically and display on TV screen will show Servo software1. First, make the CD-R/CD-RW:-Disc format The disc format must be CD-ROM Mode 1 and ISO9660 format.Writing mode The volume name (Label) of the disc must be “ALI_CODE“ & the file name of the upgrading firmware must be “PS57.BIN“. You must put the recommended to write only this file into the disc & write it in DAO ie. Disc At Once mode.2. Upgrading procedure3. Power-on the module.4. Insert the Upgrading disc. Make sure that this is the first disc that the module sees, otherwise the module will treat it as a general cd-rom disc & not perform the upgrade.5. The upgrading process takes about 10 secs. & when it finishes, the disc will be ejected.6. Power sequence the module for the new code to take effect.

Refer to instruction “Manually Ejecting of disc“. 4.2.7 ComPairFor assistance with the repair process of the Monoboard, electronic fault finding guidance has been developed. This program is called ComPair. This ComPair program is available on CDROM. The version of the CDROM for repair of the monoboard is V1.3 or higher and can be ordered with codenumber 4822 727 21637. The procedure for registration is explained in the help file of the program and in the CDROM booklet. The cable to connect the Monoboard with a PC can be ordered with codenumber: 3122 785 90017. All the hardware and software requirements of the systems, necessary for working with ComPair, are described on the CDROM
