Maybe some speaker wire is loose and sometimes makes a short-circuit. Check all wires or better disconnect all wires and try to have the receiver turned on without the speakers and see if it helps. If yes, there is issue either with the wires, connections or speakers. If the receiver still powers off without the wires, it is probably faulty and you need to send it for service.

I have a yamaha, natural Sound Av receiver RX-V483, every time that i start the unit it will shut down after 5 seconds. thank you very much


It indicates an output load problem, dis-connect the speaker wires from the back of receiver. Next power on and turn the volume right down, if the unit runs, check for shorts in the speaker wires and speakers. But if it still shuts down "with speakers and wires dis-connected" one or more of the audio output ic's is shorted and will need a professional to assess the item.

How do I connect my Yamaha RX-V463 surround sound system to an analog tv? The tv only has the three RCA jacks for audio and video. the RX-V463 has many jacks, and the manual is no help. the manual does...


Actually, the Quick Start Guide on page 6 of the manual shows the TV connection.

Consider that the TV is simply a visual element in your entertainment system and the rest will sound easy.

Run a single RCA cable from the receiver to the TV's Video IN so you can use its menus and view whatever video comes into the receiver.

Manage whatever audio you want to hear in HI-FI directly from its source to the receiver and NOT washed through the inferior audio electronics and speakers of the TV.

Unit heats up and shuts off. Will not come back on for several minutes. Sometimes plays for awhile and then powers off again.


Unit most likely heats up if not ventalited or..amplifier is overloading due to speaker impedance issues. Start with only Front L and R speaker connected. see what happens. Most new amps however have short circuit protection and cuts out as a safety if speakers are not connected properly or if speakers are loading down the amplifier. the 6.1 is fairly new.. is it still under factory warranty?

The unit does not work


check the standby power supply first and then the main power supply.also check the output transistors and fuses your problem is in one of those points, normally the standby transformer goes bad, it is the small one right next to the big one.
good luck

Shuts off within seconds of turning on.


Sounds like the "crack!" was a capacitor that got fat and blew up.

It doesn't matter what you do, that the system will power down after being on for exactly a minute? Or do you find that when you try using it a few times in a row that the shut off happens a little sooner each time? Did this suddenly start happening or was it something that began occurring gradually (meaning it would power on for an hour and then auto shutoff)?

It sounds to me like some electrical component inside is failing and that the self-protection circuitry design is kicking in. Or it could be that the power transformer is worn out and can't maintain power for more than a minute.

Keep in mind that repairs to these older electronics can end up costing as much as it would be to buy a new unit (and new units offer much more technology anyway).

No sound when using Panny plasma with RX-V3800


Let me see if I understand. You have one HDMI cable linking your TV and AVR? This is only to send video and sound out to your TV from the AVR you will not be able to send sound back over this same cable. You'll have to use the TVs audio out and connect it to an input of the AVR. The "HDMI out" on the AVR is just that Out and not In. For more questions I'd recommend checking out the RX-V3800 RX-V1800 thread over on AVSforum.com
