I have my Onkyo tx ds656 hooked up to my HDTV via the cable box. Everything works fine, except that there is a noticible delay in the syncronozation of the sound and the video. Is there any way to correct this?

"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.

Try factory reset: while holding the(CD) button on front panel,press (POWER) button.
After "Clear" is displayed the unit should be back to its factory default. :) If this dont work for you take the unit to be checked by service . :)

If your remote also controls the Cable Box you might want to look at its audio settings. Maybe you muted it.

BTW: it would be a good idea to also run video and analog audio from the cable box directly to the TV if it has speakers so you can watch and listen independent of the Onkyo.

When this happens and you just see the input label try to press the power button on the front of the cable box and see if it brings the picture up. If this does produce the picture then it is a good possibility that something is interfering with the remote communicating with the cable box. I don't know if you have it contained in an entertainment center or how you have placed your equipment but if there is glass try to clean it and also wipe down the front of the cable box and make sure there is an unobstructed view of the front of the cable box.
Good Luck.

The posabilities is power amplifier on your reciever is bad,
replays reciever or repair it.More likely this is IC amplifier located on the main board of the reciever

I am conviced that there is some failure in the unit, so without repair/replacing I rerouted my audio out from my monitor back to the audio IN jacks on the DS656 and can continue to use it until further failure.

Thanks,

Hello, I am sorry about your issue. Your hook up should have nothing to do with the remote. You should get some functions like on/off, volume control. Thank you, Onkyo, USA

Check system in TV Format Setup:
NTSC or PAL N
