Question about Yamaha Audio Players & Recorders
The Yamaha RX-V1600 receiver keeps shutting off after running OK for a while. Sometimes takes 30 seconds, sometimes 30 minutes. Checked speakers & wires, all seem OK. Ventilation is good. What else can I check to determine why it's shutting itself off?
Try to fasten screws at back of the unit ,
may sound like BS but if amp board don`t have good ground connection it can go in protection mode
happend to me on RX-V592

Hey, yeah that can be frustrating.
When you turn it up do you hear the relay or a clicking sound, then you turn it on and it comes back below the +2db?
Try unplugging All the speaker wires from the unit. Turn on the unit and listen for the click.
after the click, turn it up past the 2+ db mark and see if you hear it click or shut down. If it did not click off, then suspect a shorted crossover on one of your speakers.
2nd test is to plug in One speaker, and test it at high volume, it will not harm it. If it shuts off disconnect that speaker and try another. Only one at a time.
If it works at high volume, you need to isolate one of your speakers and i bet it has a shorted crossover that has been cooked. P.S. If one is bad, suspect they will fail at a later date.
If they all fail, use a friends speaker and try it before sending it to a repair shop.
P.S. i found one on ebay i think you can get for under $100 bucks in the box.

SOURCE: RX-V2600 shuts down
Try checking your speaker impedance. If you have 6 ohm or 8 ohm speakers make sure the impedence matches. On the front panel hold down button that says "straight effect" while pressing Stanby/On button, it will default to SP IMP 8 min, press straight effect again, if you have 6 ohm speakers, then press Standby again to exit setting. Also, double check your speaker wires to make sure they are all connected, and none are loose.
I hope this helps.

To answer your question;
First i`d like to know if there is a specific message on the front panel display before it shuts down.
One thing you can try at this time is to switch back and forth a couple of times the impedance selector switch at the back.
Another thing is to try to loosen up and re-tight all the screws at the back of the receiver(you`ll need a philips/star screwdriver) as the back panel is often used as ground for different circuits.
Try that and let me know about display messages.
I`ll be waiting for your answer

Your Yamaha RX-V1600 has an audio output transistors are mounted to a large heat sink which keeps
them cool during operation. They are electrically isolated from
touching the heat sink by an electrical insulating washer. But, in
order to keep them cool and allow for good thermal conductivity of the
heat generated by the output transistors the washers are treated with a
heat conducting grease. Over time this grease will dry out and lose
its heat conductivity ability allowing the temperature of the
transistors to rise; as the heat goes up they conduct more current and
cause the protection system to activate and shut the set down (in order
to avoid damage to the set).
You need to check or replace the transistor that's on the heat sink. Or you may contact a pro to replace it for you.

I have found there are capacitors failing through the output circuit. Look for 10, 33, 47, etc.. microfarads.In that range. I charge typicaly 150 to $200 with parts on something like this. Larry's Electronics firstname.lastname@example.org
