I had a problem today with a Yamaha O1V that I bought used a couple of weeks
ago.

I've played with it, set it up, made sure all the channels worked, no
problem. I've had it running for several hours with a couple of things going
into it, worked fine.

Today, trial by fire, in the second gig of the day, I set it up, had 9
channels running, sounded pretty good. The band got partway through their
second tune, and suddenly there was no sound. The lights were all on
properly, screen was lit up, meters showed signal coming in, but the main
outputs and the one omni out I was using produced nothing.

I turned the mixer off, waited a couple of seconds, and then back on. I got
sound for a few seconds, and then nothing. At that point I shut it off,
dragged in another mixer from the van, patched on the fly, and got through
the gig.

Yes, I will take it to a local technician, but I was wondering if anyone had
seen this particular failure type before, or do you have any idea what might
have happened?

Sure. **** breaks, and someone else's former annoyance is more likely
to become your problem than if you bought it brand new, but new stuff
breaks, too. Given the digital nature of the inner workings, it's
impossible for even someone who understands how a mixer works to
troubleshoot the internal workings to the point where you can actually
fix something unless it's a complete failure such as a power supply or
fuse.

In your case, you obviously have at least some power, and the fact
that it was working and then quit on its own means that you don't have
cockpit trouble. You might just check the word clock settings to be
sure that you didn't inadvertently click on the wrong menu thing when
making an adjustment and set it to the wrong source. That's the most
likely candidate for making all audio go away. Other than that, it'll
probably need a heart, and possibly a brain transplant.

Hope it's still a good bargain after getting it fixed. Sometimes it
isn't, as the former owner may have discovered. ;(

Having actually used one live and in the studio for years, I became familiar
with the 01v's quirks and foibles (I hardly ever get to use the word
'foible' anymore...). The most common problem is a spontaneous reset from a
poorly designed ground implementation. Yours sounds like the reset problem -
I had it happen to me a few times. There's a fairly easy fix which you'd
want to do before sending it off. I can't find my docs on it (I sold my 01v,
whaaaah), but you should be able to find it on yahoo groups - there's an 01v
group there, or google 01v and ronny morris (the group's main guru) and you
should be able to find it.

Try the fix, and if it doesn't work, then send it in for repair.
