Survey of versions:Published by FU-KC 0807 Service AV Systems Printed in The Netherlands Subject to modification/37 NTSCHDD 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 DVDN_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 DVDN_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 E2H40FISFUNCTION INDICATOR SYMBOLSNote: If an error occurs, a message with the error number appears on the screen.Message SolutionError No.Error Description PriorityCan not record on this disc.Insert a recordable disc, and ensure the disc status satisfies the recording requirements.1 An error occurs during data reading. -2There is no reply for 15 seconds in Test Unit Ready.-3Cannot write the data after trying three times.-4 An error occurs with OPC. -5 During recovery in a record. -6An error occurs even if recovery has been tried three times.-7 An error occurs in a format. -8 It cannot start an encode. -9NV_PCK/RDI_PCK is not in encoded data.-10Encode Pause condition continued for 10 minutes.-11Encode Pause condition continued in normal REC condition for 10 minutes.-12Difference in the address and cannot get Stream ID of RDI/VIDEO.-13 It is a reply that “ATAPI is not readable.” -14Cannot write the data after recovering SMALL VMGI.-15Cannot write the data after DVD-R Reverse Track.-16 An error occurs in Finalize Close. -17 An error occurs in Rec Stop Close. -18 An error occurs in PCA Full (DVD_R). -19 Safety Stop occurs during editing. -20 High Speed Disc. 221 The disc is not formatted. 522 Disc Error has occurred. 324The disc except DVD-R/RW or finalized DVD-R.1This program is not allowed to be recorded.You cannot record copy- prohibited programs.25 During the Macrovision picture input. 1126 During the CGMS picture input. 12This program is not recordable in Video mode.You cannot record copy- prohibited programs.27During the CGMS picture input.
