I'm working on a Yamaha YPT-300 electronic keyboard which I found. I completely disasembled the unit, cleaning everything (they keyboard assembly has been completely cleaned and remounted). I discovered that the b-flat and e-natural keys do not sound in any octave across the board.
The sample tune plays all keys, so I am thinking that the fault is not in the on-board chip. I have no working schematic diagram.
I am wondering if this rings any bells with anyone (perhaps minus the b-flat and e-natural ones) ?
I found this unit junked, I know it could be completely replaced cheaply, but it would be nice to straighten it out.
