Qualified technicians have the necessary test equipment and tools, and have been trained to properly and safely repair complex products such as those covered by this manual. Improperly performed repairs can adversely affect the safety and reliability of the product and may void the warranty. If you are not qualified to perform the repair of this product properly and safely, you should not risk trying to do so and refer the repair to a qualified service technician. WARNING This product contains lead in solder and certain electrical parts contain chemicals which are known to the state of California to cause cancer, birth defects or other reproductive harm. Health & Safety Code Section 25249.6 – Proposition 65 NOTICE Fuse symbols (fast operating fuse) and/or (slow operating fuse) on PCB indicate that replacement parts must be of identical designation. REMARQUE Les symboles de fusible (fusible de type rapide) et/ou (fusible de type lent) sur CCI indiquent que les pièces de remplacement doivent avoir la même désignation. ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD AND MUST BE CORRECTED BEFORE RETURN- ING THE APPLIANCE TO THE CUSTOMER. 2. PRODUCT SAFETY NOTICE Many electrical and mechanical parts in the appliance have special safety related characteristics. These are often not evident from visual inspection nor the protection afforded by them necessarily can be obtained by using replacement components rated for voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this Service Manual. Electrical components having such features are identified by marking with a on the schematics and on the parts list in this Service Manual. The use of a substitute replacement component which does not have the same safety characteristics as the PIONEER recommended replacement one, shown in the parts list in this Service Manual, may create shock, fire, or other hazards. Product Safety is continuously under review and new instructions are issued from time to time. For the latest information, always consult the current PIONEER Service Manual. A subscription to, or additional copies of, PIONEER Service Manual may be obtained at a nominal charge from PIONEER. (FOR USA MODEL ONLY) 1. SAFETY PRECAUTIONS The following check should be performed for the continued protection of the customer and service technician. LEAKAGE CURRENT CHECK Measure leakage current to a known earth ground (water pipe, conduit, etc.) by connecting a leakage current tester such as Simpson Model 229-2 or equivalent between the earth ground and all exposed metal parts of the appliance (input/output terminals, screwheads, metal overlays, control shaft, etc.). Plug the AC line cord of the appliance directly into a 120V AC 60 Hz outlet and turn the AC power switch on. Any current measured must not exceed 0.5 mA. Device under test Leakage current tester Earth ground Reading should not be above 0.5 mA Also test with plug reversed (Using AC adapter plug as required) Test all exposed metal surfaces AC Leakage Test www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com DVR-231-S 3 5 6 7 8 5 6 7 8 C D F A B E LABEL CHECK IMPORTANT THIS PIONEER APPARATUS CONTAINS LASER OF CLASS 1. SERVICING OPERATION OF THE APPARATUS SHOULD BE DONE BY A SPECIALLY INSTRUCTED PERSON. CLAMP signals for detecting the loading state are detected by the drive CPUs, and the design prevents laser diode oscillation when the CLAMP signal turns OFF. In normal operation, if no disc is clamped, the laser diode oscillation is disabled. However, the interlock does not always operate in the test mode. 2. When the cover is opened, close viewing of the objective lens with the naked eye will cause exposure to a Class 3A laser beam. Additional Laser Caution 1.

(Refer to the example) 4 Make sure the screws are tightly fastened. Please be sure that all screws are fastened, and that there are no loose screws. 5 Make sure each connectors are correctly inserted. Please be sure that all connectors are inserted, and that there are no imperfect insertion. 6 Make sure the wiring cables are set to their original state. Please replace the wiring and cables to the original state after repairs. In addition, be sure that there are no pinched wires, etc. 7 Make sure screws and soldering scraps do not remain inside the product. Please check that neither solder debris nor screws remain inside the product. 8 There should be no semi-broken wires, scratches, melting, etc. on the coating of the power cord. Damaged power cords may lead to fire accidents, so please be sure that there are no damages. If you find a damaged power cord, please exchange it with a suitable one. 9 There should be no spark traces or similar marks on the power plug. When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure connections and suitable usage. Please exchange the power cord if necessary. 0 Safe environment should be secured during servicing. When you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to prevent injuries. Please pay attention to your surroundings and repair safely. 2. Adjustments To keep the original performance of the products, optimum adjustments and confirmation of characteristics within specification. Adjustments should be performed in accordance with the procedures/instructions described in this manual. 4. Cleaning For parts that require cleaning, such as optical pickups, tape deck heads, lenses and mirrors used in projection monitors, proper cleaning should be performed to restore their performances. 3. Lubricants, Glues, and Replacement parts Use grease and adhesives that are equal to the specified substance. Make sure the proper amount is applied. 5. Shipping mode and Shipping screws To protect products from damages or failures during transit, the shipping mode should be set or the shipping screws should be installed before shipment.

Bonnet Case S 1 2 4 3 Tray panel Emergency disc ejection rod (GGF1529) Emergency disc ejection rod (GGF1529) Projection about 15mm about 5mm Cam R9 Slit of chassis Slit of drive (slide) Slit Tray Bonnet case S Tray 3 2 2 2 How to open the tray when the power cannot be turned on When the tray cannot be opened because the power cannot be turned on, it can be opened using the emergency disc ejection rod (GGF1529). (A long, thin rod about 1 mm in diameter can be used in place of the rod.) Insert the rod through the slit at the bottom of the unit and slide the projection for cam R9 in the direction of the arrow, using the rod. When the tray is popped out a little, pull it out by hand. Find the projection by inserting the rod through the slit by about 20 mm, as the projection is not visible from the outside. If the insertion of the rod exceeds 20 mm, you cannot catch the projection. 1. Diagnosis of the MAIN Assy Note 1: Do NOT look directly into the pickup lens. The laser beam may cause eye injury. Note 2: Even if the unit shown in the photos and illustrations in this manual may differ from your product, the procedures described here are common. Note 3: For performing the diagnosis shown below, the following jigs for service is required: • Flexible cable for service (GGD1436) • Emergency disc ejection rod (GGF1529) • Clip type heatsink (GGF1528) 1 1 1 Rear view Bottom view Bottom view 1 Press the � STANDBY/ON button to turn on the power. 2 Press the 0 OPEN/CLOSE button to open the tray. 3 Remove the tray panel. 4 Press the 0 OPEN/CLOSE button to close the tray. 5 Press the � STANDBY/ON button to turn off the power.

Pickup The pickup supports 16 times-speed recording for the DVD-R and 6 times-speed recording for DVD-RW. A new liquid-crystal tilt servo system is adopted for the pickup. 2. Recording-signal-processing LSI • UPD63641GC (DRIVE Assy: IC201) The recording-signal-processing module of conventional models have outside CPU, but this has been integrated into a single newly developed recording-signal-processing LSI, enabling stable performance and cost reduction. System configuration In each signal-processing LSI of the main function blocks, various processes have been integrated into one chip, which enables simpler system configuration. With the AV-signal- processing LSI at the center, video inputs/outputs, audio inputs/outputs and various memory cells are connected to it. Fig1.
