Yamaha Keyboard PSR 275

do you have keyboard circuit board for this device? It broke while cleaning it and now keys do not produce sound on higher keys?

this makes sense as in most 49 key and bigger synths theres 2 key contact C.boards upper and lower ,make sure you have the part number handy and call into syntaur and talk to eddie? I think?, next time don;t let a gorilla clean your synth, lol. If this psr 275 has on board speakers, you maybe end out having to buy a broken hold board on evibay to get thr part you need, but its also possible that the crucial part number will appear on another yamaha synth,

Thanks a lot for the response . And I will make sure the gorilla never touches it again. Haha. Thanks again
