The receiver has been in storage over 5 years in the house. I connected all components and speakers and plugged it in, and no standby light, display, or power at all. I found an internal 12A 250V fuse, but an ohm meter shows the fuse has continuity. I heard there is an internal battery, could that cause the problem if it has gone bad?

No power on Onkyo TX DS 787 Google Search

Dear Dapeng Wang
This could be one reason due to poor soldering of transformer on the PCB, so u need to check for continuity. Else another option could be the transformer might have been fused, hence u will have to check the transformer seperately by soldering it and removing it. These transformers have customed windings and so if the transformer requires replacement the old transformers winding ratios need to be checked to wind the new one. Final, last check is to see all connections and the boards strength for any crack or chipped of copper on top of the board.
Thankyou

SOURCE: Powered Or Unpowered Subwoofers For Onkyo TX-8511
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.
