Scheda contatto Yamaha CLP 340

Buona sera a tutti volevo un informazione su la scheda che allego foto se c’è una compatibile,non riesco a trovarla su internet

You will need that exact board - that chip in the centre is the keyboard scanner and it contains specific firmware. No other board will work nor replacing the chip will work because you won’t be able to load the software.

What seems to be the problem with that board ?
