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 rm does not constitute authorization, certication 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 specications are subject to change without notice or obligation to retrot. 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.

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.1. Critical Components InformationComponents having special characteristics are marked 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. Meter impedance should be equivalent to 1500 ohms shunted by 0.15 F. TO SERVICE PERSONNEL Leakage current must not exceed 0.5mA. Be sure to test for leakage with the AC plug in both polarities.WARNING: CHEMICAL CONTENT NOTICE!WALLOUTLETEQUIPMENTUNDER TESTAC LEAKAGETESTER OREQUIVALENTINSULATINGTABLE Sn+Ag+Cu+ + Sn+Cu+ Sn+Zn+Bi+ + 30 40All of the P.C.B.s installed in this unit and solder joints are soldered using the lead free solder.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: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.About lead free solder / 2RX-V771RX-V771 FRONT PANELR, T, K, A, B, G, F, L, H, J modelsJ modelR, T, K, A, B, G, F, L, H models REAR PANELSR model3RX-V771RX-V771K modelA modelT model4RX-V771RX-V771B, G, F modelsL, H modelsJ modelH model5RX-V771RX-V771 REMOTE CONTROL PANELSRAV442(R, A, L, H, J models)RAV443(T, K, B, G, F models)6RX-V771RX-V771 Audio Section / Rated Output Power (Power Amp.

Note that the capacitors indicated below are dangerous even after the power is turned off because an electric charge remains and a high voltage continues to exist there.Before starting any repair work, connect a discharging resistor (5 k-ohms/10 W) to the terminals of each capacitor indicated below to discharge electricity.The time required for discharging is about 30 seconds per each.C1076, C10821086 on MAIN (1) P.C.B.C3706 on VIDEO (2) P.C.B.For details, refer to PRINTED CIRCUIT BOARDS.13RX-V771RX-V771Fig. 1(Remove parts in the order as numbered.)Disconnect the power cable from the AC outlet.1.

Notes) Applying the power to this unit without correcting the abnormality can be dangerous and cause additional circuit damage. To avoid this, if I PROTECT protection function works 1 time, the power will not turn on even when the MAIN ZONE key is pressed. In order to turn on the power again, start up the self-diagnostic function. The output transistors in each amplifier channel should be checked for damage before applying power to this unit. Amplifier current should be monitored by measuring DC voltage across the emitter resistors for each channel.

To avoid this, if PS and DC protection function works 3 times consecutively, the power will not turn on even when the MAIN ZONE key is pressed. In order to turn on the power again, start up the self-diagnostic function. The output transistors in each amplifier channel should be checked for damage before applying power to this unit. Amplifier current should be monitored by measuring DC voltage across the emitter resistors for each channel.Cause: DC output of the power amplifier is abnormal.Supplementary information: The protection function worked due to a DC voltage appearing at the speaker terminal. A cause could be a defect in the amplifier.Turning on the power without correcting the abnormality will cause the protection function to work in 5 seconds and the power supply will be shut off.2-2.

KEY1/KEY2 menu is selected, keys become non-operable due to detection of the values of all keys. However, it is possible to advance to the next sub-menu by pressing the SCENE RADIO (forward) key or SCENE CD (reverse) key on the remote control.(Reference voltage: 3.3 V=255)P 1 - 8K Y : 2 5 5 / 2 5 5Display KEY20 11PUREDIRECT12 32TUNING>>33 54TUNING
