Question about Onkyo Audio & Video Receivers

Open Question

Onkyo AV Reciever Model #HT-R540 was given to me by a friend, it had been violently dropped by UPS, upon taking it apart noticed one of the plastic standoffs had broken through the circuit board in one of the amplifier sections near the heat sink. Bypassed the broken area by soldering wires and repaired a few cracked circuit traces, haven't found any more obvious problems. System won't power up at all, no standby light, line fuses are good and line voltage is present, and am receiving voltage output from the small transformer, a little confused about where I should measure voltage on the larger transformer. Help Please!

If the standby voltage exists, the next step is to see whether or not the clock is working. Find the main micro chip. There should be a 3 legged crystal close by. You should see this oscillate (use a scope). No oscillation = no micro control = no turn on. It is possible that the micro is bad or the crysal is bad. Also, check to be sure that the output transistors are not shorted. It is also possible that these are preventing the system from turning on.

I know that a couple of you have had the same problem with the blowing 0.47 ohm resistors. I had responded quite a wile back, but forgot to make any updates. Kostiko is correct about the problem relating to these two 0.47 ohm resistors being blown. In my case on two different Haman Kardon models, this was true, but there could also be another issue. What i have found is even after replacing these resistors, the problem appeared to still be there. What was happening was that right after turning the receiver on, the resistors would blow again. What you need to do is replace the two small ceramic disc style capacitors on the same pcb as the fusible resistors, as they could be shorted as in my case. You could remove these capacitors completely, or replace them with a similar size of the same type, as they are really just there for filtering higher frequency noises from the power supply. You can check them with your multimeter first. They shouldn't shorted even in situe. I forget the size, but they are approximately 100 nano farads. Good luck. I have done this to my AVR135, and it has been running great for about 6 months now.

SOURCE: Power will not stay on

Activated protection circuitry means that the amplifier is seeing conditions it does not like and is shutting down the power to prevent further damage.
Either you have a short in your speaker wires, in your speakers, or a blown amplifier.
Disconnect both speakers and turn on the amplifier. Does it still give the error message? If it does, your amp is blown. If it does not, carefully inspect your speaker wires and their connection. Make sure all looks good and reconnect the speakers and try it again. Still get the error message? You likely have a problem in your speaker cabinet(s).

Black and white picture from blu ray player


Run the Blue Ray straight to the TV and see if the picture is still in black and white. If it is you know that your reciever is fine and the problem lies in the player or the TV. If the picture is normal then you probably have a bad HDMI IC that will need to be replaced.

If that is true the power transformer is probably open at the primary, the secondary voltages feed the receiver and power various parts. I suggest getting it checked, my worry is the power transformer may not be available from the parts manufacture.

It has drawings on how to connect just about what ever you want.

I think you mean the model HT-S7300 by Onkyo. Here's information about it at Amazon.com, and here's a link to the owner's manual at Onkyo.

Sound from Onkyo CD player well and fine. Then connected the Samsung DVD HT-Z310 to Video3 (L/R audio in, V-in from L/R Audio out and V-out of Samsung) but no sound or nor video on TV? Tried to fix it...


What am I missing here?

There are a lot of models mentioned in this post. What are WE discussing?

* A Samsung HT-Z310 is a Home Theater System.

* An Onkyo TX-DS777 is higher-end AV Receiver that DOES have a Video 3 input which accepts composite video and analog audio.

* An Onkyo CD player is irrelevant to the TV sound in any scenario.

* Unnamed TV.

I don't see any path in your narrative that would carry audio TO the TV. Is there an unmentioned HDMI cable in here somewhere? I see no other audio outputs on the HTZ.

Are you running the HT-Z310 through an Onkyo receiver to somewhere (?) else?

The fewer hops and inteconnects a given signal experiences between its source and your senses, the better. I always run the BEST video from any source to the TV first; the best Audio to the BEST audio electronics. If that helps.

I have a n onkyo av reciever ht-r560 only the front 3 speakers go on when im using it i know the rest work and are plugged in correctly because the volume tester outputs sound through it. Is there an on...


Your sound might not be working because the HDMI and optical audio inputs might not be working.

I made the mistake of buying the Onkyo HT-560 and in less than two years all of the HDMI video inputs started intermittently breaking. Sometimes when you selected the channel both the image and the sound would not come though.

Also the rear speakers stopped working from time to time and I have to run the setup again to get them to turn back on.

I am not sure that Onkyo was ready to introduce this technology, it has been a nightmare and my stereo is going to cost almost as much as I bought it for to fix it.

Oh and there customer service was no help, they just told to bring it to an "authorized service center for repair". They had also had no idea where there was one in my city it took them a day to get back to me.

The Onkyo HT-S5100 looks almost identical to the HT-560 not sure if they are different in anyway.

Stay away from Onkyo in the future! I know I will.
