20 Most Recent Yamaha RX-V2400 Receiver Questions & Answers

download RX-V573 service manual and read starting from P.25 to look for what type of protect involved.

If you've replaced the fuse and it blew again, you most likely have a blown Amp. And when an Amp goes other things can go with it as well.

Hi Seems like you have a shorted output channel, remove all your speaker connections and try again, if the problem persist, good chances are that you need to replace a couple of power transistors, let me know if you need more help, I've fixed some Yamaha amplifiers with this problem Good Luck Miguel

The setup may depend on your TV and other components and how you plan to use the system. Does your TV have analog or digital audio outputs? The receiver has analog and both types of digital inputs (coaxial and optical). Use the best cables that you can. You can get all cables at online cable stores for much less than at the electronics big box stores. I'll assume that you already have the speakers connected to the receiver. Next you can either connect your devices (cable box, blue-ray player) the receiver's inputs. Then connect the receiver's video out to the TV. This is great if you will only listen to the devices with the home theater system. Then you can also connect the TV audio out to the receiver for the OTA TV audio. For this you probably need component video cables and audio cables. These are all cables with RCA plugs.. Then get another audio cable for the analog or digital optical output of your TV. For some TVs the only audio out is the headphone jack. In that case, you also need a 3.5 mm to RCA adapter (the simplest is 3.5 mm M to RCA F/F for connecting to an RCA audio cable). For this method, you won't have to turn off the TV speakers most of the time; the TV won't have any audio.Alternatively, connect each device audio/video out to the TV's input and then only connect the TV's audio out to the receiver DTV audio IN. Since the receiver doesn't have HDMI, this is the best option if your devices have HDMI out. For this, use the appropriate number of HDMI cables and the analog or digital optical audio cable from the TV to the receiver. Then turn off the TV speakers and enable the external speakers in the TV menu. You can connect to any of the receiver's inputs. If you use the labels, you'll find it easier to turn on the inputs. If you have any devices with composite video output, use the same basic steps as for the component The documentation for the RX-V2400 is available at the Yamaha product site: http://usa.yamaha.com/en/products/audio-visual/hifi-components/stereo-receivers/rx-v2400_black__u/?mode=model . You'll need to be a registered Yamaha user (Easy-Pass) to read the manual online.I hope this helps. Please add a comment with your devices (including the model of the TV) for more specific information. Cindy Wells

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Not unless your speaker is has fused input protection. if no speaker will produce any sound, it may be the output transistors. Make sure the balance is balanced, and correct polarity. Get an RA(return authorization) for the Yamaha USA Repair center if you can't fiqure it out. The do good work for reasonable rates.
Sorry I couldn't make it easy for ya.

I'd investigate the intervening video-carrying cables.

Consider whether you actually NEED to route video through the receiver in the first place. Is all that extra cable and 2 extra interconnections actually doing any good? Apparently not.

In my rig, I run high-end video only to my TV and high-end audio only to my receiver. No problemos.

The most common problem found on FixYa for Audio Video Receiver's is:

My receiver say's "Protect" or turns on then off. What's wrong? Seven times out of ten it is a shorted speaker or speaker wire. To determine your exact problem, the first step is to disconnect all speaker wires "at your receiver" Next: Turn the receiver back on. If your receiver still says "protect" or turns off, it needs to be serviced. If your receiver stays on; reconnect your speakers one at a time and power back up after each speaker. You may find that after reconnecting all speaker wires it works! Most commonly the small braids of wire from the + to the - have touched and have caused the problem. In some instances, you noticed the problem only when turning the volume up. either way, make sure the exposed wires to your receiver are no longer than 1/2" long and are completely under the screw down terminal or slide in. When you've found the wire or speaker with the problem, your receiver will go back into "protect" At this point, disconnect the wire from the speaker at the speaker that may be causing the problem then test again.* Note* Make sure speaker wires do Not touch each other as this Will cause a short! If you turn the receiver back on and it stays on, you now know the problem is in your speaker itself. To test your speaker, you will need a multimeter. Set it to ohms resistance and touch the speaker terminals, if there is a short internally the meter will read "1......" If it's an analog meter, it will peg to the right. There's your problem. Now, within any speaker there are quite a few possibilities as to what could be causing the problem. Most common is a blown coil and the speaker needs to be replaced. Some speakers have internal crossovers (usually floor standing speakers) and may have a shorted or burnt board (usually very visible brown burn marks on the board) and can possibly be repaired if your handy with a soldering iron. Now, if you disconnect the speaker wire at the speaker and it still says "protect" Check your wire for the obvious cut or nail thru the wire if possible. If your system has wiring that runs behind walls, you may need to use your meter again. Disconnect the wire at both ends, keep the ends separated, put your meter on ohms resistance and touch probes to the + and - wires at one side. If the meter pegs to the right or reads "1...." the wire is shorted and needs to be replaced or repaired at the short. Hope this helps.

You would connect the rx-v2400 record output to the power amp input. You might need to Clarify your question here in more detail. Larry's Electronics

Check the impedance ratings of your speakers. Sherwood, the actual manufacturer of the NS-R2000 receiver, suggests that you use speakers with an eight ohm impedance if you have only one pair attached. If you have two pairs of speakers attached, the impedance rating of each pair should be sixteen ohms.

This is because Sherwood wired the receiver such that an additional pair of speakers is placed in a parallel circuit to the first set. When this is done, the impedance (resistance) of the load seen by the amplifier drops. As resistance drops, you get closer to a short circuit (no appreciable resistance).

Many other receivers wire the speakers in series, which causes the impedance to go up.

Personal experience seems to suggest that the amplifier is OK with a four ohm load on it. It does run warmer with a four ohm load, which is what you'd expect. It's when you have multiple sets of four ohm rated speakers that you will get into trouble, as this means the receiver only sees a two ohm load. This will cause overheating and shutdown.

At this point the power transistors in the amplifier may have been damaged. It may require repair. Fortunately, replacement parts are readily available (though not from Sherwood or Insignia). If it continues to shut down, stop using it. You could end up burning out your speakers.

Throw on a couple of shrimp it and let us know when they're ready. You need a pro to look inside it.

make sure volume is up on the ipod.....bc you can control vol. on your receiver with the ipod
