Wx7 service repair manual

Unread post by Juliaan » Wed Mar 26, 2014 3:37 pm

Hello to all wx users. Is there someone who own the repair manual for the yamaha wx7? I have some troubles, becuase after ten minutes if playing the wx7 stops working for 1-2 days. Also i have the gain to max level.... I think it could be a pressure sensor, but before buying it i wanted to read the service manual in pdf. Help is appreciated. Thank you

That's a tough one .....

Here's the user manual: :idea: http://mybreathmymusic.com/wp-content/u ... nglish.pdf :idea:

Unless you want to buy the service manual online, or taking a risk from some of the dodgy download sites,
I strongly recommend that you contact your local/regional Yamaha customer service, they usually help out for free.

I have a pdf copy of the WX7 service manual from when I diagnosed and replaced the capacitors in mine to get the WX interface working a couple of years ago. It doesn't appear possible to post it here, and I'm worried that I wouldn't be permitted to. Is there something I can help you with?

What a great service! :-)
This gives me hope that my question might be answered here too: I'm living in Germany and my third WX 7 isn't reliable any longer. So I got three instruments that need technical service. What can I do?

Folks. Sorry I haven’t been on here for a while and got around to uploading. If anyone has any specific requests I can try to provide an image of whatever page you need.

Cloud burst - I have a wx7 with a single key E that sticks - When I put one drop of liquid wrench at the corners of the pivot where it attaches to
the body, and work it a few times it is fine. Do you have a page that relates to the attachment rail for the keys? Or maybe some liquid silicon?

Thanks - Michael Goyette

The service manual contains the following, relevant to this:
- Exploded diagram.
- Part numbers for shaft, key post and key
- A service bulletin which describes how in the lower section, dropping the instrument can cause a rib to break, allowing the lower switch board to slide down inside the instrument with the result that certain keys in the lower section do not take effect unless they are pressed firmly. The fix is an additional bracket which can be installed inside the lower section in order to hold the lower switch board in place.

Your issue doesn't sound the same - the E key is simply sticky. I think from memory the keys and posts (spacers) can be moved slightly along the shaft if teased gently. Perhaps something is wedging the movement very slightly?
