Hiya,
best suggestion is find another one on ebay and use your existing one for parts.
I've done this with my SY22-I paid $120 for the last one I bought.

Does anyone know where I can get a good keyboard with working keys for a
Yamaha SY22? It's been repaired so many times over the years and now I just
want a new assembly. Any help appreciated. Anything in Toronto would be
greatly appreciated.
