This may have been posted before by other people. If so, please feel free to direct me to the right location.
I have a UMC-200 that has developed some problems. It runs on the .47 firmware.
1) startup time has decreased considerably. It took about 5 seconds to load it’s settings and firmware, now only about one. Regularly it won’t output any audio after start up. When I then switch if off and on again, it seems to work ok.
2) sometimes it seems to start up fine. But then it won’t respond to any command from the remote or front panel buttons. The only way to turn it off is to switch off the mains power using the switch on the back panel.
3) When I turn the unit back on, it loads firmware and setting and every time I switch it on after having cut off the mains power, I get two error messages: “no dsp 2 code” and “osd firmware not match”.
Can I solve this with a firmware flash or update, or this unit just about dead?
Thanks for any tips and input!
James.

Based on #3, sounds like there is a FW issue. But, I would call Emotiva before trying to re-load it.

Seconded, call Emotiva. It may even still be under warranty - those have 5 years.

Thanks! Will try that. Although I’m on the European main land. Also, I bought the unit used and don’t know when, where and by whom the original purchase was done. Never hurts to ask, though...

This could also be the power source problem(capacitors C18 & C19 gone bad). Pictures on page 2 have the specs for these capacitors, if indeed they are the problem, and at least a few members here have done the repair as well. emotivalounge.proboards.com/thread/41827/umc-infinitive-loading-after-power |

I agree with LC that it's more than likely a failed power supply board. While my UMC-200 worked fine for me during the time I owned it (about 2 years), it failed within a year of my son taking ownership of it. It exhibited the same symptoms for him as you're describing here. The "fix" was a new power supply board. I know it's not going to be easy for you, but I also agree that you should call Emotiva directly. Considering that you're located in Europe, they "may" be able to simply ship you a replacement board (along with instructions), or direct you to a service provider who can repair it for you. I can tell you, though, that if the original owner did not transfer the warranty, it will not be covered. Good luck and best wishes...  |

Sounds like a power supply board, I did the capacitor replacement and that carried my over until Emotiva shipped me a replacement board. The board I did the capacitor replacement on also failed some months later so I used the replacement board then. There is some change in the later boards as it has never given me a problem since. The capacitor replacement is easy, anyone with soldering experience can do it. But ultimately I'd suggest getting a later version power supply board from Emotiva. That's a simple plug in replacement.
Cheers

Just spoke with an Emotiva service representative. I explained the problem as in my message above. He quickly stated it must be the PSU-board, that a few capacitors need replacing and actually require an upgrade in value.
He sent me a fee photo's of the parts that need replacing, their correct values AND the voltages that should be present on the PSU outputs.
With that information I should be able to fix the unit myself. After that, we'll see how long it lasts. It should be able to work for long enough, so that I can leisurely look for a replacement pre/pro.
Although I'm recovering from a minor surgery, I'll try to go out to get the parts tomorrow.
So, fingers crossed and I'll keep you posted!

I’ve opened my UMC-200 and identified the caps that need replacing according to the instructions. Visually, the look fine, though...
I guess I’ll just replace them and see what happens...

I was thinking something in the place LC was saying. Some bad Caps maybe. Could be just as simple as that. Since all the logic control is handled in the low voltage world on the UMC.

Things are getting a little strange.
I’ve replaced the specified caps with the ones they should be replaced with, taking great care to match polarity. I’ve disconnected all other pcb’s, then connected the psu and the device to the mains, engaged the switch. I measure none of the voltages I should be measuring according to the supplied information. I only measure +/-5V where it should measure that Voltage. But nowhere do I measure +/-12V where I should find it
Does this mean that my entire psu has died? Or is something else wrong? I’m not new to fixing minor problems in electronic equipment and I know my way around a soldering iron.
Looking at the psu pcb, it says v3.0. No idea if this is the most recent revision or not.
Hope someone can help!
James.

Success! I thought that the only way to know for sure if it worked or not was to just hook everything up and see what happens. Weird thing is that although I only measured 5V on the psu, on the other PCB’s I measured 12V just fine.
After reconnecting mains power and turning it on cold, I no longer got the “NO DSP2-CODE” and “OSD FLASH NOT MATCH” errors. To be sure I decided I’d better do a new firmware flash. Which turned out to a disaster all on it’s own. I couldn’t get it to work under Wintendows 10, no matter what. I had a friend set up a Win7 Virtual Machine. Somehow that worked. So i’m on firmware version .52 now. My biggest “worry” is that l’ve lost my EQ-settings. But there are worse things in the world...
Will test extensively tomorrow.

Glad to hear replacing C18 & C19 worked for you. As for your P-EQ settings, it just means you'll have to reacquaint yourself with REW!!!  |

Hi !!! Since a few days ago my UMC-200 did not open the SETUP tab on the GUI Menu. The arrow on the screen cursor cycles through INPUT up to ZONE (and vice-versa) but does not dip into the SETUP option. And as all adjustments once made on the SETUP tab were lost and as I cannot enter this tab after the bug, the majority of this component's goodies as a processor per se was deemed uneffective ---- a sad end of affair with this awesome equipment. Any way of salvaging my UMC-200 ? I think this must be a software-based failure. Attachments:

Hi !!! EMOTIVA sent me the latest FW release and I tried the upgrading many times but it FAILED MISERABLY to correct the issue I reported about  After stubbornly insisting on it I almost ended with a brick because the upgrading process froze and stuck a pair of times and I was in dire despair at those occasions  I emailed EMOTIVA back and will wait a word from their staff again, if will be any of course...

I'm sorry that you are having these issues. If you don't hear back, they are most responsive over the phone. You can call and talk to Keith, Nick or Damon. |

This ^^^ is 100% exactly what my UMC-200 is doing. Same error messages, same results when I did what James did. Mine is running on the 52 firmware. Right now it is not usable. It was being erratic before and it would work once started, but now it won't even boot up.
Is there a happy ending to this problem? Anything new since this was posted in 2018?

Call Emotiva service. I sent my umc200 back under warranty (only had a couple months left) For similar reasons. Power supply issues. Replaced c18, c19, and one more I believe. The Umc200 has been working fine since, a happy ending. If your unit is not under warranty good luck. |
