Onkyo Forgets it's input settings during power outages

I have been enjoying my Onkyo TX-DS787 for 8 years now. I use it to switch video and audio inputs on my home A/V system. Just recently, when I would turn it on I would get no video or sound. After going through the OSD setup I found the inputs had reverted to their "default" values, not the ones I had programmed in. This has happened quite often and usually happens after a brief AC power outage. Re-seting the inputs fixes the problem and restores my video and audio until the next power outage. Is there a battery somewhere in this unit for holding the programming memory? I would appreciate any help I can get. Thanks, Hal

    I am having the exact smae problem with mine. If I plug it into an external UPS, do you think that will solve the problem?

    Hi - Have a Kurzweil PC88 that worked perfectly, until recently when a single note sounded louder than the rest. To fix the problem, I followed an on-line video that amounted to removing, cleaning, and reinserting the pickup contacts in the correct order. Now, a new problem developed. All keys play except eight keys beginning at middle C# up to G#, which no longer sound. Thinking it was a pickup problem, I ordered a new contact strip and replaced the octave starting at middle C. Still did not solve the problem. (The piano was not turned on during the repair.) What went wrong? How can this be fixed so I have my 8 keys back?
    Thanks for your help.

Yes there is ,,, it is located on the same board that has 3 fuses on it, you will have to unplug the unit before disassembly, and remove the top cove and bottow covers,,,, you will have to de-solder a small battery pack surrounded by either blue or yellow heat shrink,,, please not the polarity before removal, as putting it in wrong will cause a non- memory retaining situation to continue...I hope this helps

How to connect Sony dvd player to onkyo TX-8511 receiver

The TX-8511 is an older AV receiver with only composite video inputs. Your DVD player may not provide this type of output as it's not capable of HD video. If your dvd player has a composite output with a Red, White & Yellow set of outputs, that will connect into the Video 2 inputs on the receiver. Your TV will need to connect up to the Video2 or Monitor output. You'll need a set of composite video cables with the red-white & yellow RCA type plugs.

Here is a link to the manual for this receiver:

Bose Cinemateonnect

Hi lechap,

With the indulgence of IB4G2008 as per his last post Feb 13.....

If I figure your concerns right, they are:
1. You have an iPod on an Onkyo IPod dock that you want to connect to an Onkyo receiver TX-302;
2. You have an Onkyo receiver TX-302 that you want to power a set of Bose Cinemate speakers;
3. the connectors on some do not fit or are not the same;
4. you want to know what goes to where.

If I may suggest:
a. connect the L/R Audio Out of the Onkyo IPod dock to the L/R Audio IN of VIDEO 1 using a pair of RCA to RCA cable. Connect the S Video Out of the Onkyo IPod dock to the Video IN of VIDEO 1 using an S Video to RCA Video cable. Thereafter if you want to watch a movie or play music from your iPod, you need to choose Video 1 in the Onkyo receiver TX-302. You can of course choose any other VIDEO 1~3;572fcdc.jpg34ab5d3.jpg

b. all other source/devices may be connected similarly using the same scheme on any of the free VIDEO / AUDIO inputs
c. of course the MONITOR OUT goes to your TV or projector.

With respect to the Bose Cinemate, it would not be technically correct to connect the Bose Cinemate speakers straight to the speaker out of the Onkyo receiver TX-302. You need to install another set of speakers to the speaker outs of the Onkyo receiver. The Bose Cinamate system's TV AUDIO could be connected to the TAPE OUT (or the AUDIO L/R OUT of VIDEO 1)

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Power outage overnight. Now, Onkyo TX-SR603X no

Depending upon the type of power outage, you may have more of a confused receiver than a defecive one. Try unplugging the unit for an hour or so to see if that resets the whole thing back to "normal". If not, then further investigation with a scope or logic analyser will be required to determine whether the problem is with the internal CPU or a defect on the data lines. Unless the reset works, this is not likely to be a DYI repair.

Hi, I am having trouble connecting my Nintendo Wii to my Onkyo TX-SR507

Take the adapter cable from the Wii that plugs into the back of the Wii and converts the output(audio/video) into RCA style pin plugs, you will have: RED=right channel audio, plug it into any of the red audio INPUT on your Onkyo, then you will have WHITE=left channel audio, plug it into the other white INPUT jack next to the red plug on the Onkyo, then you will have YELLOW= video(picture) that will go directly to the yellow video INPUT on the back or side INPUTS of your TV.
Then when you want to play the Wii, set the input mode on the Onkyo to the inputs that you connected the red and white plugs into, then change the input on your TV to which ever the input is labeled on your TV in which you plugged the yellow plug into, you now will have sound comming from your Onkyo and the Wii up on the TV screen ready to play. Good luck!

Onkyo TX-SR606 power on default input setting and hissing sound

I had the same problem for more than a year but just lived with it. The solution is to reset the receiver to factory defaults. Page 96 of the owners manual, "turn the unit on and while holding down the VCR/DVR button, press the ON/STANDBY button. CLEAT will appear on the display and the unit will turn off". Problem solved!

I have "Onkyo TX-SR304E" and PS3. Will this rcvr support PS3 in all means? Is there any special setting hat I ned to follow to get the best from my rcvr as well as PS3? Pls advise. Your help much...

what u can utilize on your tx-sr304 is the optical input at the back of the receiver. connect an optical cable from your PS3 into the receiver then follow these steps:
*make sure that the digital input on the front panel of your receiver matches where you placed the optical at the back of the tx-sr304 (either OPT1 or OPT2)
*all you have to do is keep pressing the digital input at the front panel until it goes to OPT1 or OPT2 (preferrably stay on DVD mode)
AFTER completing this go to your PS3 settings:
go to settings / then go to sound settings / then audio output settings / then set it to DIGITAL OUT (optical)/ then play and enjoy.....ü

1st time using component video connections on my onkyo

Yes, switch to the video input that you are trying to configure (i.e. video 1-4). Press the menu button on the receiver or the remote and cycle to video settings. There should be a setting that says "video output" or "output" - set that to component. You may also have to configure the Input for that particular setting. For instance, if you have an HD tivo going into component 2 but you want it to be Video 1. Select Video 1, hit the menu button and scroll to video setup. Select video input setup and cycle it to component 2. Next, use the menu to cycle to video setup, select video output, switch to component. This should solve your problem. As a sidenote, you may also have to configure the audio in/out if you're using digital coax or optical. Let me know if this works.
