Stage 3 Issue

[MB5251]

Was playing a song last night in the Dflat Major. At the Middle C Register when I play the Dflat and Eflat simultaneously nothing sounds. Same if I hit Dflat & D simultaneously, or D & Eflat simultaneously. After a while I noticed that it will work intermittently but not very often. I would assume this is a hardware issue. I can all other keys simultaneously on the keyboard and it works fine.

Thoughts?

Just to confirm, you can play each of the keys individually but not together correct?

First thing I would do is open up the case and snug down the ribbon connectors -- which were a known problem with some of the early Stage 3s. After that, I'd take a look at blowing out the key contact mechanisms with compressed air.

Yes for the most part. There are times though after trying to play them simultaneously and they don’t sound that they won’t play individually for a little bit….

You may have some dust, dirt, grime etc. in your key contacts that are conspiring. If the prior suggestions aren’t helping, you could open it up and spray compressed air on the key contacts or some Electro Wash.
