My UMC-1 (purchased 2010) has the orange standby light around the power button, but won’t start (just stuck orange) after some power brownouts, then a power cut this morning. Tried turning it off at the back, waiting, then on. Also pulled the power plug out, waited 5 minutes, but nothing works.
I have it plugged into a very fancy Belkin PureAV (like $1000 worth) power filter surge arrester. Also tried it plugged into a different power outlet.
I tried the three fuses inside, they have continuity, but if they blew would the power button still light up?
Anyone had this? Any ideas? I have emailed Emotiva (and I did search the forum).
I'm in Tasmania, Australia so not easy (or worthwhile ) sending back to Emotiva to diagnose/fix.

Time to move on my friend...no more umc-1 parts as I was told..while it could probably be the powersupply not sure they even have spares for that left either. You could buy one and have it posted out but the other gotcha might be the front panel and if that's gone then it's game over.
There might be a small encapsulated fuse on the power board, I forget but I'll go look at the diagrams when I get a min. Pm me if you want to take this offline as you are clearly out of warranty

Yes looks like. Local repair bloke says even if you could repair some overheated components on the power board, other bits on other boards would most likely have gone or go soon. Not impressed to only get 5 years out of a supposedly premium, and pricy, item. Also crappy product support to dump them after such a short time. Parts and support for high end stuff like this should be available for decades from a manufacturer.

its basically a computer with a bunch of media interfaces...if you can get reliable support for a computer after 5 years...even 3 then thats stellar but seldom going to happen. UMC-1 was not what I would call expensive for what it was. AVR tech moves on fast these days, see if you get more than 1-3 years support out of any other mainstream brand AVR/PREPRO...I doubt it.

That's not my opinion. I'm a computer tech. If I build a computer I like a client to get at least 5 years out of it, if not 10. That's computers, HiFi does not evolve so fast, or at least you don't have to evolve. If I'm happy not to have the latest cutting edge specs, I should be able to get a lot more than 5 years from this stuff. Particularly a simple power supply should be replaceable at reasonable cost. Particularly as that was the impression Emotiva gave when I purchased it.
Anyway, grumbling aside, I have the option to get the XMC-1 at US$1781 (A$2388) shipped (plus any GST/import duty). I have an XPA-5. Really not sure given the above issues with the UMC-1 and generally unsupportive (to international buyers) attitude of Emotiva. I suppose I could try it and resell them both if I'm not happy.
There's rumours of HDMI 2/HDCP 2.2 capability for the XMC-1 'soon' (any month now), but we all know what 'soon' means with Emotiva. Is it worth waiting for that? My current TV is 1080p and no plans to upgrade it unless it dies so it would really only be planning for the future.

Why don't you email Emotiva and ask for a spare ps at cost and see if they have...I don't like your chances but it can't hurt to ask. I know other parts are not available, and HDMI boards definitely been gone for a while now.
I might have a working one (repaired in my parts Bin) but I am traveling the next few weeks...pm me if you like to continue this offline.

You can buy a used umc-1 for under $300.00 on e-bay, they are not expensive.

eBay US maybe, but then there's getting it here (Australia). Tried Emotiva. They won't sell parts. Quite annoying for the sake of a cheap part.
Now I have to shell out three times what the UMC-1 cost to replace it. Is it worth it if Emotiva reckon 5 years is the expected life of their products? I'd be pissed if I only got that from a chain store item.

I'm in Tasmania, Australia so not easy (or worthwhile ) sending back to Emotiva to diagnose/fix. I had the same issue with my UMC-200 a few years ago and turned out to be a couple of bad capacitors in the power supply. If I were you (if you are somewhat handy with a soldering iron), I would replace the electrolytic capacitors in the power supply and see if that will fix your problem. I also own a UMC-1 and expect to have to do that sometime in the future. Sometimes, the tell-tale sign of bad electrolytics are a raised top like they're expanding in size. Of course, another would be if the electrolyte has leaked out of the cap onto the pcb. But, you might not see either situation and they're still bad. You can remove them and test them. But it might be cheaper to just purchase new ones than buy a tester to check the existing ones. If you can't find ones that match the voltage rating and capacitance rating exactly, keep in mind when replacing caps to make sure the voltage rating is at or above the rating printed on the old cap. Also, make sure the capacitance rating is at least as high as what's printed on the old ones. Try to stay close on the ratings if you can to keep within the design specs of the power supply. Oh, one more thing... most power supply electrolytic capacitors are polarized... when replacing, make sure you make note of which side is labeled negative and put back in the same polarization. Good luck.

caps seem to be a bigger problem in most of the Emotiva gear I have had to repair that is on all the time...like standby supplies etc. XSP was a big problem on 240 volts. it seems they really didn't get the 240V stuff up to spec from the gear thats come thru my workshop.
that said Emotiva was pretty good with shipping spares for units under warranty.

Might have to pop the lid on my older emo gear for a visual inspection. There really is no excuse for poor caps in power supplies in expensive gear. caps seem to be a bigger problem in most of the Emotiva gear I have had to repair that is on all the time...like standby supplies etc. XSP was a big problem on 240 volts. it seems they really didn't get the 240V stuff up to spec from the gear thats come thru my workshop. that said Emotiva was pretty good with shipping spares for units under warranty.

Sadly I guess Emotiva is not really build like expensive gear...it's also pretty old model now so can perhaps expect some powersuuply issues. Burned out resistors too I've seen in many I repaired.

I always had terrible humming coming from the UMC-1 and XPA-5. They just don't work well in 240 volt countries I reckon.
I gave up on it and bought a very expensive ex demo Bryston SP3.

I'm in Tasmania, Australia so not easy (or worthwhile ) sending back to Emotiva to diagnose/fix. Honestly its difficult to say exactly what the root cause is. I would look at a couple of things first, but in either case I doubt it is worth the effort. The first is the power supply. It sounds like the standby power supply is running because the front panel micro is running but the main supply could be dead and not coming on line (most likely the issue). The other is the video board since it has the secondary controller. The front panel is the standby micro that starts up the unit but once that happens the secondary micro takes over. If its dead, then the unit won't respond to the helm. If its the power supply it is possible to repair but tracking down what has failed could easily exceed the value of the unit. If its the video board, then it can't even be repaired. Both the micro and the main video switchers are end of life and the chips are not even made anymore. I am sorry to be the barer of bad news, but I think it may be time to look into a replacement. Lonnie

I take issue with that wiz. I have designed a lot of "expensive" gear over the years. Remember we are an OEM builder and cap failures are common with in the industry. Our service logs show less then a 1% failure of caps which is by industry standards excellent and far better then any other company I know of. Just my opinion though. Lonnie

I just removed a post as it was off topic re XPA-100 failed caps but the fact remains that caps are now the biggest issue I have with many brands...not just Emotiva
