Onkyo TX-DS989 not staying on

Hello, Sorry, if the receiver does not turn on we can't do any troubleshooting. I suggest having your receiver serviced or traded in. Thank you, Onkyo USA

Hello Steve, your receiver would need to be serviced or traded in. Thank you, Onkyo USA

If Zones are turned on or, if a mobile device connected to the Front Input is charging (MHL), the HYBRID STANDBY indicator won't light. See the TX NR515 owner's manual at http://filedepot.onkyousa.com/Files/own_manuals/TX-NR515_English.pdf for more info.

Sorry but it does sound like an Amp failure and testing the unit for other electronic component failure will be needed

Hello, Just try with Ebay or Alibaba sites. OK.

The trouble is almost certainly bad capacitors in the power supply. As they age they become very slow to charge up (think of them like buckets that store electricity for other parts to draw on, and it's taking them much longer than normal to fill). As a result it's a while until the rest of the circuitry starts working properly. But once they've charged, the thing works like it should.

If you know someone with some electronics skills, they could check the capacitors and replace any that are visibly bad or don't measure correctly. Or you could see about getting the receiver serviced if you have a shop in your area. Musician's supply stores are a good place to check, or ask retailers if they have anyone they suggest. Since the receiver is basically okay otherwise, having this repaired would probably be worthwhile.

I have the same problem and it is not speaker wires, cables, or dumb remote codes (really, remote codes.) I'm taking mine in for repair, and not reliying on straw grasping, speculative solutions.

could be a bad soldered joint or loose connector, even a bad earth in the secondary power circuit.

The only thing to test would be to disconnect all speaker wires at the receiver then turn it back on. If it still won't turn on, it's an internal power supply issue and will need service. If it turns on, post a comment and I can walk you thru further troubleshooting. Hope this helps

The outputs are blown and will require repair.
