RX-V2500/DSP-AX2500SERVICE MANUALIMPORTANT NOTICEThis manual has been provided for the use of authorized YAMAHA Retailers and their service personnel. It has been assumed that basic service procedures inherent to the industry, and more specifically YAMAHA Products, are already known and understood by the users, and have therefore not been restated.

RX-V2500/ DSP-AX2500

WARNING:

Failure to follow appropriate service and safety procedures when servicing this product may result in personal injury, destruction of expensive components, and failure of the product to perform as specified. For these reasons, we advise all YAMAHA product owners that any service required should be performed by an authorized YAMAHA Retailer or the appointed service representative. IMPORTANT: The presentation or sale of this manual to any individual or firm does not constitute authorization, certification or recognition of any applicable technical capabilities, or establish a principle-agent relationship of any form. The data provided is believed to be accurate and applicable to the unit(s) indicated on the cover. The research, engineering, and service departments of YAMAHA are continually striving to improve YAMAHA products. Modifications are, therefore, inevitable and specifications are subject to change without notice or obligation to retrofit. Should any discrepancy appear to exist, please contact the distributor's Service Division.

WARNING:

Static discharges can destroy expensive components. Discharge any static electricity your body may have accumulated by grounding yourself to the ground buss in the unit (heavy gauge black wires connect to this buss). IMPORTANT: Turn the unit OFF during disassembly and part replacement. Recheck all work before you apply power to the unit.

1. Critical Components Information Components having special characteristics are marked s and must be replaced with parts having specifications equal to those originally installed. 2. Leakage Current Measurement (For 120V Models Only) When service has been completed, it is imperative to verify that all exposed conductive surfaces are properly insulated from supply circuits.G

EQUIPMENT UNDER TEST

AC LEAKAGE TESTER OR EQUIVALENT

INSULATING TABLEG G

Meter impedance should be equivalent to 1500 ohms shunted by 0.15F.

Leakage current must not exceed 0.5mA. Be sure to test for leakage with the AC plug in both polarities.

CAUTION F2: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 10A, 125V FUSE. CAUTION F2: REPLACE WITH SAME TYPE 10A, 125V FUSE. ATTENTION F2: UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 10A, 125V.

WARNING: CHEMICAL CONTENT NOTICE!The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (where applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and possibly other entities) to cause cancer and/or birth defects or other reproductive harm. DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON WHATSOEVER! Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose eyes to solder/flux vapor! If you come in contact with solder or components located inside the enclosure of this product, wash your hands before handling food.

Process

Among some types of lead free solder currently available, it is recommended to use one of the following types for the repair work. Sn + Ag + Cu (tin + silver + copper) Sn + Cu (tin + copper) Sn + Zn + Bi (tin + zinc + bismuth) Caution: 1. As the melting point temperature of the lead free solder is about 30C to 40C (50F to 70F) higher than that of the lead solder, be sure to use a soldering iron suitable to each solder. 2. If lead solder must be used, be sure to remove lead free solder from each terminal section of the parts to be replaced and from the area around it completely before soldering, or make sure that the lead-free solder and lead solder melt together fully. 2

Starting DIAGPress the STANDBY/ON key while simultaneously pressing those two keys of the main unit as indicated in the figure below.

STANDBY/ ON


Keys of main unit /

Turn on the power while pressing these keys.

Starting DIAG in the protection cancel modeIf the protection function works and causes hindrance to trouble diagnosis, cancel the protection function as described below, and it will be possible to enter the DIAG mode. (The protection functions other than the excess current detect function will be disabled.) Press the STANDBY/ON key while simultaneously pressing those two keys indicated in the figure above. At this time, keep pressing those two keys for 3 seconds or longer. In this mode, the SLEEP segment of the FL display of the main unit flashes to indicate that the mode is DIAG mode with the protection functions disabled.

STANDBY/ON 3 FL SLEEP

CAUTION!Using this product with the protection function disabled may cause damage to itself. Use special care for this point when using this mode.

Canceling DIAG[1] Before canceling DIAG, execute setting for PRESET of DIAG menu No.11 (Memory initialization inhibited or Memory initialized). * In order to keep the user memory stored, be sure to select PRESET INHIBIT (Memory initialization inhibited). Any protection history will remain in memory. [2] Turn off the power by pressing the STANDBY/ON key of the main unit or the STANDBY key of the remote controller.

When there is a history of protection function due to excess current Version (1 alphabet) 1

Cause: An excessive current flowed through the power amplifier. Turning on the power without correcting the abnormality will cause the protection function to work immediately and the power supply will instantly be shut off. Note) Applying the power to a unit without correcting the abnormality can be dangerous and cause additional circuit damage. The output transistors in each amplifier channel should be checked for damage before applying any power. Amplifier current should be monitored by measuring across the emitter resistors for each channel.

Voltage display in % %

Cause: The voltage in the power supply section is abnormal. Supplementary information: The abnormal voltage is displayed in % based on 5V as 100%. Turning on the power without correcting the abnormality will cause the protection function to work 1 second later and the power supply will be shut off.

Voltage display in % %

Cause: The temperature of the heat sink is excessive. Supplementary information: The abnormal voltage is displayed in % based on 5V as 500%. Turning on the power without correcting the abnormality will cause the protection function to work 1 second later and the power supply will be shut off. * Additional causes of protection can be due to loose connections, associated components, CPU, etc. * For the protection voltage value, refer to DIAG menu No.12 described later.

History of protection functionWhen the protection function has worked, its history is stored in memory with a backup. Even if no abnormality is noted while servicing the unit, an abnormality which has occurred previously can be defined as long as the backup data has been stored. The history of the protection function is cleared when DIAG is cancelled by selecting PRESET RESERVED (Memory initialized) of DIAG menu No. 11 or when the backup data is erased.

During signal processing, the condition before execution is maintained. When K0/K1 menu is selected, keys become nonoperable due to detection of the values of all keys. However, it is possible to advance to the next submenu by turning the VOLUME of the main unit. When using this function, note that turning the VOLUME more than 1 click would cause the volume value to change. * The figures in the diagram are given as reference only.

I AMP ADJUSTMENT / Confirmation of Idling Current of Amp Unit Right after power is turned on, confirm that the voltage across the terminals of R319 (MAIN Lch), R320 (MAIN Rch), R325 (CENTER), R326 (SURROUND Lch), R327 (SURROUND Rch), R321 (SURROUND BACK Lch), R322 (SURROUND BACK Rch) are between 0.1mV and 10.0mV. If it exceeds 10.0mV, open (cutoff) R291 (MAIN Lch), R292 (MAIN Rch), R295 (CENTER), R296 (SURROUND Lch), R297 (SURROUND Rch), R293 (SURROUND BACK Lch), R294 (SURROUND BACK Rch) and reconfirm the voltage. Attention If the idle current exceeds 10.0mV after an amplifier repair, first check for a defective component before cutting the bias resistor. Confirm that the voltage is 0.2 mV ~ 15.0 mV after 60 minutes.
