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

I own this receiver, and 18db is damn loud. Granted - your room might be significantly larger than mine with your speakers spread much further apart, or your speakers might be much less efficient than mine (this means that they want more power than the receiver can dish out - I have whatever speakers came with the "YAMAHA Home Theater in a Box" [the model that came with the HTR-5830]), but I'm pretty sure that the receiver doesn't get any louder (or at least not much). My suggestion is to turn down the volume to about -20db and work up from there after the movie has started. It might be easier to test the volume using music. The negative sign is deceiving - I rarely bring mine up to 0db. Also check the resistance - there's a red switch on the back of the receiver that switches between 6 and 8 ohms - make sure that it matches your speakers' resistance. If turning down the volume doesn't work, then post the problem again. Hope This Helps.

These units have protection circuits that will prevent the speaker relay from engaging if there is a problem detected. There is also a circuit that causes a delay in the engaging of the relay to allow the amp to "settle in". This prevents the old "thump" that was common in older models when the set was first turned on. In your case, either the RC circuit is faulty causing excessive time to pass before turning on the relay, or there is excessive voltage floating around that the protection circuits are detecting and thus preventing the relay from turning on.

In any case, this will require additional diagnosis using some test equipment. This is not a problem that will be easily resolved remotely. Please bring this unit to a repair shop for an estimate. Once you have that info, we can assist with the actual repair.

Is it going into protect mode???
If so, check your speaker connections. Make sure there are no loose copper wires hanging out, and that your splices are clean at both the receiver and the speaker.
