Technics Organ - U40

Hi... I please need help with the following: I played on my organ Tuesday evening and everything was 100%
Wednesday morning I switched on the organ and there was no sound. All buttons are on and red. The Orchestral Conductor lights are on and cannot seem to be switched off, it is unresponsive. The green buttons at The Voice Setting Computer is also not responding and those lights are not coming on. Please can someone give me an indication of what the problem can be. Will be much appreciated.
