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.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.I CONTENTSTO SERVICE PERSONNEL .......................................... 1 IMPEDANCE SELECTOR ............................................. 1 FRONT PANELS ........................................................ 2~3 REMOTE CONTROL TRANSMITTER .......................... 3 REAR PANELS .......................................................... 4~5 SPECIFICATIONS .......................................................... 6 INTERNAL VIEW ........................................................... 7 DISASSEMBLY PROCEDURES ................................... 8 SELF DIAGNOSIS FUNCTION (DIAG) ................... 9~24 AMP ADJUSTMENTS .................................................. 24 DISPLAY DATA ..................................................... 25~26 IC DATA ................................................................. 27~32 BLOCK DIAGRAM ................................................. 33~36 PRINTED CIRCUIT BOARD .................................. 37~52 IC BLOCK DIAGRAM ............................................ 53~54 SCHEMATIC DIAGRAM ........................................ 55~58 PARTS LIST ........................................................... 59~72 REMOTE CONTROL TRANSMITTER .................. 73~76100754P.O.Box 1, Hamamatsu, JapanRX-V420/RX-V420RDS/HTR-5440/HTR-5440RDSI TO SERVICE PERSONNEL1. 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.GWALL OUTLETEQUIPMENT UNDER TESTAC LEAKAGE TESTER OR EQUIVALENTMeter impedance should be equivalent to 1500 ohm shunted by 0.15?F. Leakage current must not exceed 0.5mA. Be sure to test for leakage with the AC plug in both polarities.INSULATING TABLEG GRX-V420/RX-V420RDS/ HTR-5440/HTR-5440RDSWARNING: 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.IMPEDANCE SELECTOR WARNING: Do not change the IMPEDANCE SELECTOR switch setting while the power to this unit is on, otherwise this unit may be damaged.435 (17-1/8&)130 (5-1/8&)Unit : mm (inch)121 (13/16&)151 (5-15/16&)16 (5/8&)352.5 (13-7/8&)389.8 (15-3/8&)21.3 (13/16&)I IMPEDANCE SELECTOR?

CAUTION: When canceling this function, check that DIAG menu No.10 PRESET (memory initialization inhibited/reserved) has been set. [To keep the user memory, be sure to select “INHI” (initialization inhibited) from the No.10 PRESET menu before canceling the DIAG function.]?

Repair the faulty parts according to the displayed history. (*2) When an excess current or any other faulty condition is found with the power source, DC, etc., the protection function forces the power to turn off.I PROTECT display(When the power is turned on without this abnormality corrected, the protection function activates the moment the power relay is turned on to shut off the power relay. The display will not light.) Cause: There is an abnormal current flow to the power amplifier. Supplementary information: As the current of the power transistor of each channel is detected, the abnormal channel can be identified by checking the current detect transistor. 10RX-V420/RX-V420RDS/HTR-5440/HTR-5440RDSPS PRT display(When the power is turned on without this abnormality corrected, the protection function activates about 1 second later to shut off the power relay. Display may not light if there is an abnormality with the power supply for the display.) Cause: There is an abnormality in the power supply section (voltage). Supplementary information: As the power from the following sources is detected, it is possible to determine where an abnormality exists. Main (5): Transformer secondary winding CB222 (AC voltage) Input (4): Regulated power supplies ± 25, +12A, +12B, -12, +5DDC PRT display(When the power is turned on without this abnormality corrected, the protection function activates about 3 seconds later to shut off the power relay.) Cause: A DC output from the power amplifier of any channel is detected. Besides the above possible causes, the cause may be a disconnected connector or around the CPU. PS PRT and DC PRT displays include the abnormal A/D value in % (voltage value obtained by considering 5V as 100%). Concerning this value, refer to DIAG menu No.11 AD DATA CHECK.RX-V420/RX-V420RDS/ HTR-5440/HTR-5440RDS? Protection historyWhen the protection function has activated, its history is stored in memory with a memory backup. Even when no abnormality is noted while the unit is being serviced, an abnormality which has occurred previously can be defined as long as the backup data has been stored. The protection history should always be cleared before returning the unit from service. The protection history is cleared when DIAG is cancelled by selecting &RSRV& (Memory initialization) from the setting items of the DIAG menu No.10 PRESET or when the backup data is erased.?
