How are you? I mix on a Yamaha 01V that I use mostly for live shows.
Recently when I turn on the mixer the led goes on the fritz displaying lines. After a few on and off attempts I finally get the system to boot, but it crashes in seconds right before channel light up. The light stays on the screen but the OS or anything shuts down. I have checked the fuse, and that seems to be fine, but It happens every time.

Has anyone experienced similar issues with the Yamaha 01V. Is there a solution?

We had a similar problem with a Fostex unit but it fixed itself and no problems. Maybe a power supply problem or the CPU is getting ready to die or you simply have a loose or coroaded power supply connector somewhere within the unit.

Best of luck!

It could be anything related to power supply, static blown ram/chips, etc, etc.
Yamaha's aren't field serviceable. Take it to your authorized service center and let them deal with it.

There is a known weakness on the 01V with the power supply earthing. This is well detailed in the yahoo 01V users group here -

You can also post on this forum and be assured of getting some help. If you're OK with a soldering iron you should be able to do this yourself. Otherwise get the details and find a local tech to do it for you.
