SH-201 Few dead buttons - repairable?

Post by StepLogik » Mon Aug 17, 2009 4:43 pm

The last four patch selector buttons ( 5 - 8 ) as well as the write/cancel buttons on my SH-201 have quit working. I guess this is the first casualty of my move to Boston :(

Does anyone know if this is repairable without having to order a whole new panel PCB?

I've yet to take it apart, but will probably do so tonight. I'm expecting a monolithic SMT mess that is utterly impervious to repair :lol:

Anyone have schematics or service manual?

it could be a failure/disconnection of the Connecter CN3 on the MAIN BOARD and/or the Connecters CN2/CN3/CN4 on the PANEL-C-BOARD.

I have the service manual.

how much to ship a copy to me, assuming that doesn't violate any agreements you might have with roland?

do those specific buttons share a common line that could be bad? I'll try to re-seat the connectors you mentioned.

Connectors looked solid but i "jostled" them a bit and that seems to have fixed the problem. i guess the connections are very spotty on those really thin ribbons.

Not much to see inside the 201.

Also, it takes 28 screws to remove the back panel!!
