SX PX552 - Need Service Manual / Circuit Diagram

Hi Folks, I just bought an SX PX552 piano which has power (LED on and DC voltages on the amplifier board), but no display or sound. Does anyone have a service manual or circuit diagram? There is a "Test" port on one of the boards ... how can I use this…

Hi Folks,

Many thanks in advance.
