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. RX-V2/RX-V2RDS/ HTR-4/HTR-4RDS CONTNTS TO SRVIC PRSONNL... IMPDANC SLCTOR...

10 RX-V2/RX-V2RDS/HTR-4/HTR-4RDS Starting DIAG Press the POWR (STANDBY/ON) key of the main unit while pressing the FM/AM key and the INPUT MOD key simultaneously, and DIAG will be activated. Keys of main unit FM/AM INPUT MOD Starting DIAG in the protection cancel mode If the protection function activates and causes hindrance to trouble diagnosis, disable the protection function as described below, and it will be possible to enter the DIAG mode. (The protection function other than the excess current detect function will be disabled.) Turn on the power while pressing these keys. Press the POWR" (STANDBY/ON) key while pressing the FM/AM" key and the INPUT MOD" key simultaneously. At this time, keep pressing the FM/AM" key and the INPUT MOD" for seconds or longer. In this mode, SLP in the FL display of the main unit flashes. CAUTION! Using this product with the protection function disabled may cause damage to itself. Use special care for this point when using this mode. RX-V2/RX-V2RDS/ HTR-4/HTR-4RDS Canceling DIAG Turn off the power by pressing the POWR (STANDBY/ON) key of the main unit or the STANDBY key of the remote control unit. CAUTION: When canceling this function, check that DIAG menu No. PRST (memory initialization inhibited/reserved) has been set. [To keep the user memory, be sure to select INHI (initialization inhibited) from the No. PRST menu before canceling the DIAG function.] Display at the start of DIAG On the FL display of the main unit, an opening message (including the version and the protection history) appears for a few seconds followed by the diagnostic menu display of. ANALOG BYPAS. Opening message DIAG menu display When there is no protection history (*) Version ( alphabet) After a few seconds (*) If a protection function history has been recorded, the type of the protection function and the voltage value recorded last are displayed. If the protection function activates after DIAG has been started and the power is turned off; When the protection function (*2) activates, the protection function history appears on the display and the power turns off. 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. 9 I PROTCT 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.

11 RX-V2/RX-V2RDS/HTR-4/HTR-4RDS PS PRT display (When the power is turned on without this abnormality corrected, the protection function activates about 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 (): Transformer secondary winding CB222 (AC voltage) Input (4): Regulated power supplies ±2, +2A, +2B, -2, +D DC PRT display (When the power is turned on without this abnormality corrected, the protection function activates about 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 V as %). Concerning this value, refer to DIAG menu No. AD DATA CHCK. Protection history When the protection function has activated, its history is stored in memory with a memory backup. ven 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. PRST or when the backup data is erased. RX-V2/RX-V2RDS/ HTR-4/HTR-4RDS Operation procedure of DIAG menu and SUB-MNU There are 4 MNU items and some SUB-MNU items as well. DIAG menu selection Main unit: Select the menu using (Forward) and (Reverse) keys of PROGRAM. Remote control unit: Select the menu using (Forward) and (Reverse) keys. SUB-MNU selection Main unit: Select the sub-menu using (Forward) and (Reverse) keys of PRST/TUNING. Remote control unit: Select the sub-menu using (Forward) and (Reverse) keys. PROGRAM DIAG menu selection PRST/TUNING SUB-MNU selection Use these keys for DIAG menu selection. * Only the remote control keys indicated in the MNU List can be used to select a sub-menu directly. Functions available during DIAG In addition to the DIAG menu, functions as listed below are available. Input selection, CH input Center/Rear/Sub-woofer level adjustment Muting Power on/off operation Use these keys for SUB-MNU selection. * Functions related to the tuner and the set menu are not available. * It is possible to confirm Menu No.2 "IF STATUS" while keeping the signal process (operation status) of each DIAG menu by using the INPUT MOD key of the main unit.
