Question about Harman Kardon Audio Players & Recorders
My AVR 20 II receiver hav been with me for about 6 years now.
the problem is,the sound will loss (silent) intermittenly.It happen randomly.
its kinda like this normal-silent 2 sec-normal-silent 1 sec-normal again for long period then it happen again.It does not matter if the volume is high or low and happen on all surround option.The receiver display did nok flicker when it happen so its not power problem i guess.I have open the unit and there are no burnt or spoiled component.
Speaker used are Infinity SL50 front speaker,,JBL Flix2 center and surround speakers.
At first i tought it was caused by heat but putting two cooling fan doesnt seem to be helping.

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 RECEIVERS 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 dont 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

SOURCE: center speaker no sound
had the same problem and SOLVED it.. the problem is caused by bad solderjoints on the pcb with the pre-out connectors on it. the solution is to take this pcb out and inspect it visually for signs of loose/oxidized solderpoints - indicated by a faint gray 'ring' near the soldered wire. just resolder and there you go! an amp as fresh as on its day of birth.. enjoy

There's a button that turns the speakers OFF right above the headphone jack.

Testimonial: "@dunnbiker Very true on assumptions! I've tried everything the manual suggests. Right now, nothing is connected to the unit, but upon power up, I get the SP:OFF display (which is not seen in the DEMO mode). I will try the headphone jiggling idea and see what happens."
