Onkyo TX-DS777 does not retain settings after power loss

No internal battery, a large "SuperCap" on the main board acts as one. Look for C8007, 0.1 F, 5.5V.

My Onkyo TX-DS777 lost power. I believe this to be a blown fust, but am uncertain, any thoughts?

It seems like the internal fuse to me, too. But you could check to make sure that the receptacle works (maybe you've got a tripped breaker).
The manual also suggests unplugging and re-plugging the unit to clear "external noise" from the "computer circuits," but something tells me that you've already tried that.

Power problem


It may only need to be reset, unplug it for a min. plug it back in and try it.
Check your owners manual some will tell you how to reset them.

Also check for a jammed switch, press every switch one by one if one doesn't move that is the problem, you can possibly unjam it with a small screwdriver.

But it could need servicing.

Power light on, unit will not turn on with push button

When power was intermittant, were there any other discrepencies or audible power deprivation to the speakers? Your problem has many possibilites from fuses to major amplifier problems to common power supply failures. Being intermittant then dead may still be a simple fix, but not without some physical intervention of test gear. Sorry, Jaszy
