Question about Onkyo TX-DS787 Receiver
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
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

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.
