Question about Onkyo HT510 Receiver

1 Answer

Immediately shuts off when turn on.

My stereo has always worked fine. The other day my pup shewed a speaker wire. It was fine then the next day I went to turn it on and it immediately turns itself off. I checked the reciever itself and does not "smell fried", My dvd changer works ok if not hooked up to the reciever, but when hooked up to the reciever I have to hold the buttons down for any function to work. Any ideas what may be wrong with my reciever? Is there an internal fuse or relay switch?

Hi! I buyed a Stereo Panasonix SA-CH74 Model 14 years ago. It was a great thing. But I noticed a problem with it. After one or two years F61 error begun appearing on display and stereo switched off....

F61 usually means the amp has detected a short or a severe microprocessor error.

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.

Check for loose speaker connections at the speaker as another possible root cause for intermittent shutdown.

Powers up ok but when i turn anything on it immediately goes back to standby as soon as there is any signal.

you have a short circuit somewhere in the speaker wiring. or a problem with one of the speakers. try disconnecting all the speaker connections the re-connect one at a time and you will probably fine the problem one.

Receiver Sr5200 shut down in 5.1 mode

chances are you have the volume too loud and the speaker wires are crossed.
all speaker wires need to be with the positive on the right and negative on the left if you have them anywhichway than it will work on low volume and not a very good sound.
look closely at the wires and they should have a red or so color on one side or the wire jacket itself will have a round side and a flat side

Yamaha 5.1 says Check SP Cable and shuts down - has been fine.

It has nothing to do with the input you choose. A speaker wire is shorted. Disconnect each one in turn and try it. The last one disconnected before it stops failing is the one.

Samsung 5-Disc 1200-Watt Home Theater Surround Sound System My Home Theatre System is keeps shutting down by its self. before it shuts down the screen says protection mode and then shuts down. i have...

If the unit shuts down almost immediately without sound, you have an electronic failure of the audio amplifier.

However if you must play the unit up above quiet background levels, you likely have a shorted speaker wire. With home theater systems, you have the luxury of trying different surround modes and speaker level settings. It's not unusual, for example, to have a loose wire strand going to the center speaker. In stereo, the system works fine. As soon as you switch to a surround mode, the amplifier senses the short and shuts down to protect itself.

Check those wires really close - I bet you'll find it there.

Pioneer posted this on it's Canadian Web Site:

Poor wiring connections, bad wires or a bad speaker may cause this. As you increase the volume, you will increase the amount of current you are drawing from the receiver. To troubleshoot this issue, try the following:
  1. Disconnect each speaker wire connection. Inspect for any frayed or damaged wiring and replace it.
  2. Check the impedance of the speakers; make sure they are properly rated for your stereo. In most cases, they need to be 8 ohms. Only a few Pioneer receivers will support lower impedance.
  3. If the problem still continues, try these steps:
    1. Turn the receiver off.
    2. Remove one speaker.
    3. Turn the receiver on.
    4. Increase the volume.
If the receiver overloads, repeat steps 1-4 (selecting a different speaker each time). If you disconnect a certain speaker and the receiver no longer overloads, have this speaker checked at a service center. It could have a bad speaker component, like a tweeter, sub-woofer, or even a bad crossover.

Immediate shut

Unplug all the speaker wires first, then unplug the unit from the wall for at least 24 hours, The plug back in without the speaker wires or anything else plugged in. Then see if it goes to the protection mode. If it does not, plug in each speaker at a time, and see if any speaker, when hooked up, makes the receiver shut down. If it does shut down, My friend, I'm afraid you will need to take this unit into a repair shop, OR get a new unit. Good Luck

Yamaha Receiver RX-V630 not working (resets itself immediately)

This maybe an easy one. Have you unhooked all the wires going in to the stereo. "SP wires" means you have wires to the speakers are touching and the stereo is shutting down to avoid overloading. Hope this helps...

Won't stay on

If you have the service manual there is a section that shows you how to get the protection mode history with the codes. You can also reset all of the protection from the service menu listed above. Be careful in doing so but have fun if your fed up with it not working.

Shutting down

Try first to disconnect all your speakers and see if the sdame thing happens. if it dosent, turn off and start to connect up one speaker at a time. BUT always turn off unit while connecting speakers. Keep connecting till you get to the one that makes the system shut down. Then check the wires for splices cuts or shorts and make sure the ends where they connect to the speaker and reciver isent shorted. if it doesnt work with all the speakers disconnected theres a short in the unit and if its new take it back. Good Luck
