Musical Keyboard Yamaha Portasound PSS 21

A Musical Keyboard, Yamaha Portasound PSS21 left on a shelf becomes dead. I became the lucky one chosen to perform an autopsy.
Measuring 61cm x 20cm x 6cm and weighing about 2Kg, it is a handy keyboard for picnics or even private dining at restaurants.
I decided to open up the keyboard to locate the cause of the problem.
