Onkyo TX-SR500 Receiver Questions & Answers
Have to turn the volume near max on my Onkyo receiver to hear TV
it sounds like a source level adjustment refer to your users manual and see if there is a way to turn the SLA up and if not then a small amp can be bought or purchased to boost the sound from the tv. check out the Fiio E5 for examples it might just do the trick
When power button turned on, receiver powers up
I have had the same problem with my new Onkyo HT-S 5305B (A/V Receiver + 5.1 speakers). To solve this, try to follow "Troubleshooting" guide that came with your system. I followed it 2-3 times. In my final attempt, when system was not shutting down but stayed-n with no sound, I played with the setup and tried changing audio adjustment, input, dimension etc. and slowly I was able to get speakers up one after the other. It's working fine now.
However, I am little concerned that why such a high-class Onkyo system failed in less than two days, forcing me to troubleshoot. - Apurva
My Onkyo TX-SR500 receiver stays in standy/on mode.
It may be your amplifier protection circuitry is being activated and shutting down automatically. This is usually caused by a faulty output transistor in one or more of the channels. I recently repaired my Onkyo TX-SR500 which had this problem.
Using a multimeter on ohms check between C and E on each of the ten output transistors. I found Q6051 and Q6061 to be short cct on all pins. Once you have located the faulty channels check the adjacent components for open or short cct.
I replaced the following components,
Q6051 (2SD1047)
Q6061 (2SB817)
R6091 (2.2ohm fusible)
R6081 (2.2ohm fusible)
R6101 2x 0.22ohm 2W
Q6031 (2SD2061)
The amplifier now works perfectly, cost of the parts is about $15-$20.
If you don't feel confident doing this yourself just find a friend or tech who can do it for you.
Onkyo mute channels. When turned on, one or more
follow this steps and fix it. God bless youThe speakers are not connected properly.
Check the speaker connections.
The Mute function is activated.
Turn off the Mute function.
The volume is turned all the way down.
Turn up the volume.
Neither set of speakers is selected (if unit has A/B buttons to select sets of speakers).
Press either A or B to select a set of speakers.
Both sets of speakers are selected, but only one set is connected (if unit has A/B buttons to select sets of speakers).
Press the appropriate button to deselect the speaker outputs which are not connected.
The receiver is set to TAPE MONITOR (if applicable).
Turn off TAPE MONITOR mode.
Headphones are plugged into the main unit.
Unplug the headphones.
The source selector is set to the wrong source.
Select the proper source.
The impedance of the speakers is less than the rating for the system.
Use speakers with the correct impedance rating.
Onkyo shorted speaker
HelloDisconnect the speaker connections and switch ON the set. Set a multimeter to measure volts, and measure the voltage acorss the shorted speker terminals at amplifier end. There should not be any voltage at all. That is, the voltage measures at the speaker terminals must be approximately equal to Zero. If hter shows any voltage, make sure that the output amplifier to that side is shorted. never connect an other speaker, even for checking. It will also burn out.Connect speaker to this channel, only after rectifying the fault, if any.
My TX-SR500 has a problem,
Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on; or it may turn on but produce no audio to the speakers.
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.
