How can I eliminate audio Hum from Onkyo TR-SR705 AV Receiver?
I am trying to use a new Onkyo TR-SR705 AV receiver.When first setup, I noticed a low 60Hz hum without any of the inputs active, and a louder hum when the "phono" select is made on the receiver (even though the phono was turned off and is grounded to the receiver).The hums were the same from the front speakers and fromheadphones.
There are no video output connections. I am trying to solve the audio hum before completing the theatre setup.
After removing all inputs (including antennae), and all speaker wires, the hum on the headphones is the same.Moving the unit to another power circuit made no difference.
Can there be any conclusion other than that the receiver is defective?

There might be a grounded component inside the circuit board. Hopefully its just a wire that needs to be resoldered. Better check the internal of the unit for visible loose component or parts connection.

Hi tmister318 this is Mike Houston of DISH Network, there are codes thatwill set your DISH Network remote to your Onkyo receiver the codes are 660,642, 678, 264 and 662. I will send alink to help with the setup for this. http://www.dishnetwork.com/SupportSection/remote-setup
HDMI ports 5 and 6 on the back of tv no longer are working. (We had a series of thunder storms so don't know if that is how they got damaged or if it was something else) but moved HDMI input cable to HDMI port 4 on tv and everything is working again. Service call placed for warranty service on tv to repair bad ports.
Actually, I don't think your problem is a matter of buttons pushed on a couple of remotes at all. I looked around the web and noted several instances that instructors may have confused readers, including those of the notably confusing user manual, as to how many of the multiple video inputs can be used simultaneously, and I believe you should choose the highest fidelity video input, whether optical or even composite, since your symptoms seem those of a situation where several video inputs are superimposed one upon another, which is an absolute no-no, and can ruin your video amplifier.
Check for multiple video input hookups before you burn out the vid-amp.
Okay I am not positive I have this right as far as the configuration of the system but I will give it a shot. If you run the 722 to the tv using rca's you get the hum. I assume this as there are no inputs on a dish 722 receiver. I can suggest one possible solution which is to buy an rf modulator. It will convert the signal from rca to coax so you can connect as you wish. There are several types out there so ensure you get the one that converts from rca to coax. I would suggest the following configuration: Remove all connections from tv and hook 722 up via rca's to rca input 1 on the tv, check for hum. If it is present now you need a new 722 as it is passing to much power thru the connection. If there is no hum connect your cable and tivo to the tv via whatever inputs you have remaining. Lastly connect the DVD player to another input that is free. You will have to system through your inputs to view the three sources but should not have the hum. I hope this solves your issue. Thanks for using Fix Ya and let me know if I can be of further assistance.
I am probably stating the obvious here but here it goes:
If the 625 is connected to the tv using coax directly try using the RCA jacks to connect directly to the tv. If the 625 goes through a peripheral first, eliminate that peripheral and conect directly to the tv.If the problem exists with different media connections still at the same tv you can remove the coax off of the TV1(3-4) output on the back of the 625 and attach it to the TV2(CH60-73) output.You would then change your tv channel from 3 or 4 to ch 60air or 73 cable(which will be the same channel that TV2 is normally on in the remote room without the 625) Once you are on the right channel you will be able to tune TV1 to your local channel using the TV2 remote. If the audio is good here it eliminates the TV coax input on the TV1 and the coax cable connecting it as the source of the problem. You will have already eliminated any other inputs on the same tv as being faulty by using the other connecting media leaving you with the internal components of the receiver as being faulty. In this situation I know of no recourse except the obvious.
You should have no problem with this. I have provided a picture of your model below for clarification. One end of the coax will attach to the 3-4 OUT on the back of the receiver and the other end will go to the NEW tv's coax input. If your set has two coax inputs you may have to select the port that you connect to in the menu portion of the tv. If the new tv does not have a coax input you can use RCA jacks which are red/white and yellow and connect those to the TV 1 output on the back of the receiver and the other end to one of the inputs on the back of the tv- this will require you to select the input source you connect to again e.g AUDIO 1, AUDIO2 etc. If you have a VCR run the coax from the 3-4 on the back of the receiver to the antenna inon the back of the VCR -usually the top port, then run another coax from the output- bottom port to the coax input on your tv. I hope I have been of some assistance to you and Thanks for using Fix Ya. If I can assist you further please let me know.
I have a sr605 Onkyo receiver and just hooked it up to a new Mitsubishi 73" and I could not get the picture to work, sound did though. Here is the problem the Onkyo is HDMI 1.3 but TV calls for HDMI 1.3a. There is a big difference between the 2 and the Onkyo will not work with TV. The newer model TV'S say in the manual Category 2 V 1.3a. You need to make sure that all your parts are compatable. It makes a big difference.
