SOURCE: onkyo tx-ds676 dead no power up
power down the amp totally to reset processor, then try again. If still no go, may have blown internal fuses- replace and try again
.... or failed thermal fuse in mains transformer. this is a workshop repair as it involves mains voltage that can kill :)

Greg- Powered subs are better than non-powered subs (also known as passive subs), anyway I see the TX-8511 has no sub pre-out on the back panel, so you need to decide what sub you will use and run from the receivers left and right speakers output into a subwoofers speaker in from speakers then back out to speakers, look at the back of a subwoofer and you will see like 4 sets of speaker hookups 2 in and 2 out, what this does is takes the low end or bass and drops the signal to the subwoofer then takes the mids and highs out to your left and right speakers, unless your regular left and right stereo speakers have large woofers a sub is the way to go.

The same rating fuse will work as long as the "Ampere" side is the same. The "Voltage" of the fuse determines the input Voltage that will be allowed. As long as you are sure that the input will only be 120V the fuse will work properly but I would recommend using the same Voltage and Amperage of the original fuse since it may fail again. Given that information if it does blow again I would recommend taking it to a specialist. A 3 Phase fuse is only available to 3 Phase inputs (480V). Unless you live in a large compound your house doesn't have that type of capability.

you may want to try a factory reset by pressing and holding vcr1 button while pressing the power button. do this with the unit on. It will reset back to factory default. so any saved setting will be lost and you will have to set again to your settings.

SOURCE: Onkyo TX-DS898 Memory Loss
THEY USE A MEMORY CAP.ITS LOCATED ON THE MAIN PCB ASSEMBLY, REF. C7701 ONKYO PART NUMBER IS 3000078/ WITH THE UNIT TURNED OFF MEASURE THE VOLTAGE YOU SHOULD HAVE APPROX 5V IF NOT THE CAP IS BAD. ALSO MEASURE WITH UNIT ON AND YOU SHOULD ALSO MEASURE 5 V IF NOT THEN THE SUPPLY VOLTAGE GOING TO THE CAP IS BAD.
