Looking for replacement volume control for onkyo txsr603x

"Volume knob not working on my onkyo tx-ds656"
replace the volume knob but check the volume control IC first such as voltage and whether an analog signals come out by an oscilloscope.

and " lost remote " Check if the onkyo remote is working, by:
(1)point a mobile or a smart phone camera at an onkyo remote control.
(2)Don't take any photo.
(3)Now the remote picture is on the mobile or smart screen.
(4)Press any remote control key.
(5)White flashing light can be seen if remote is ok.
(6)If remote is fine, replace the remote senor on tx-ds656 with same part number.

Hi Travis, please make sure that in programming volume limits are not turned on. Thank you Onkyo USA

Maybe the cheapest and the best way to get the knob is to check ebay and buy the hole receiver for parts or check the link below. :) hope it helps

Hi ,try cleaning your volume control ,here is a video so you can DIY or contact your local service. :)

The Onkyo TX8011 is a Stereo Receiver. Two ways to connect:
1) The HD Cable box should have an audio out (typically red and white). Connect this to the Obnkyo CD input (red and white). The volume may be controlled with the Cable box remote or Onkyo remote. The TV volume may be muted or ON.

2) Connect LCD TV's audio out to Onkyo TX8011's CD input.
This is not a great way to set up, as the TV volume, when moved high, will attenuate (over load) the amplifier, leading to a jarring sound on the speakers. To avoid this, the TV volume should be ALWAYS FIXED low.. say about 30%. Only the Onkyo's volume should be adjusted while watching.

Hope this helps.

Hi, unfortunately this remote does not have the ability to program to your Onkyo receiver. You must use your original Onkyo remote to control the volume of it. If you need a new Onkyo remote you can purchase one from Replacement Remotes. You can also buy a universal remote to program and work for both your units, so you will not have to keep switching back in forth between remotes. If you would like a universal I suggest getting the RFS200, this remote will even work if your receiver is not in direct line of site.

Never use maximum volume for troubleshooting. The errant switch or control that you eventually find and flip will suddenly release the amp's full power and you'll destroy your speakers. If a signal isn't audible at 1/2 volume it's probably not there.

Look for a misplaced Mute or Tape Monitor control or Multichannel Analog Input selected.

There is a good chance that a common control may have developed a high-resistance or 'dead' spot through idleness and is causing your symptom. Turn the POWER OFF and operate every control throughout its range a number of times, especially rarely-used ones like Tape Monitors and the Mute control.

Turn the volume to something reasonable and see if that helped.

Hi,
Looks like your volume control switch is not working on the left side, you can check it by tapping the knob on the volume control and sound will come out on left side.
The only way to get the sound again is to replace the volume control or pull out the volume control and open it up to clean the contacts in it.

Hope that helps you out!
Thanks for using Fixya!
