Question about Yamaha HTR-5940 Receiver

1 Answer

Turns on then off.

My Yamaha HTR-5940 worked fine for 1 months. Now it does not turn on. It turns on for a second when I press the front power button and turns off.

    I've been having the same problem with the DLSU1-9Vdc. Can't find a replacement part. Could something else be wrong with the unit. It keeps on shutting down.

    John...I'm a Yamaha/Denon repair hobbyist....mostly >3 years old units. Have an HTR-5940 with blown right channel (I don't have repair manual for this one). I replaced all obvious fried components (power and driver transistors and maybe 5 resistors). Bias voltages still too high (around -3V)...I think bad zeners. Interestingly, the right and left channels are designed with 2 zeners (1/2 watt), the others have only one (Why?). What are the specs for the two zeners in the right/left channels? I had a couple of 5.1V laying around and did no good. Thanks for any advice you can provide.

It probably needs a set of output transistors, 2 pre-amp transistors and a 5.6v zener diode. Possibly a resistor or two. I've fixed many of these. Definitely a job for a pro.

Yamaha HTR-5990 Receiver


I JUST EXPERIENCED THE SAME SITUATION HERE IS THE SOULTION YAMAHA SENT ME TO RESET THE SYSTEM HTR-5990 YAMAHA HTR-5990 FACTORY PRESET PROCEDURES All models require the STANDBY/ON button to be turned OFF to start the reset process. NOTE: The remote control cannot be used during the reset procedure. All necessary buttons to complete the reset process are located on the front panel of the receiver. This procedure is not intended to correct intermittent shut-off symptoms or problems MODEL: HTR-5990 (U.S.A. model/s) (BEFORE YOU CONTINUE, PLEASE READ THE ABOVE NOTES!) 1. Before you start this procedure, locate the MASTER ON/OFF button and the STRAIGHT/EFFECT button on the Front Panel of the unit. 2. MAKE SURE THAT YOUR RECEIVER’S MASTER ON/OFF HAS BEEN TURNED OFF. 3. With the Right Hand, press and hold the STRAIGHT/EFFECT button. With the Left Hand, press the MASTER ON/OFF button and HOLD both buttons for no more than “3” SECONDS, AT THE SAME TIME. SP IMP. * 8 MIN. will appear on the display, which indicates you are in the Diagnostics Mode. 4. Rotate the PROGRAM KNOB to the right (ONCE) until the display reads PRESET *CANCEL. 5. Press the STRAIGHT/EFFECT button (ONCE) and the display will change to PRESET RESET. 6. Turn the unit off by pressing the MASTER ON/OFF button. 7. Wait 5 seconds, then turn the unit on by pressing the MASTER ON/OFF button. You have now reset your component to the factory settings. NOTE: Yamaha receivers don’t have to be reset during normal operation. It is not recommended that you reset the receiver unless a setting has been changed that you are not aware of, or the receiver is not operating properly. The reset procedure will clear an incorrect setting that might be causing abnormal operation. GOOD LUCK
