Hello,

I recently purchased a used Kenwood M-9000 SS micro Hi-Fi system, but unfortunately, the unit is not functioning correctly. When I power it on, the display is stuck on the message "Waiting for PC Wizard", and the device becomes completely unresponsive – it does not react to any buttons or remote control inputs.

From my research, it seems that this issue may be caused by a missing or corrupted firmware, particularly related to the Sunplus SPHE8202 chipset used inside the device.

I have been trying to locate the correct firmware file (possibly DVDROM.BIN) that matches the hardware (the board ID may be BD305890BB9B50), but so far, I have had no luck finding a working download source.

Could someone please help me with:

• The correct firmware file for this model

• Instructions or guidance on how to recover the system using a USB flash drive

• Any experience with solving this "Waiting for PC Wizard" message on similar Sunplus-based systems

Any help or direction would be greatly appreciated!

Thank you in advance.

Best regards,
Dejan Todorović

Hello, I am in a repair KENWOOD KRF-X9995D. Let me know if anyone is aware of how to reset the processor. That is about a year ago I had the same problem with another amp of the same model! So this is the second unit can not repair! The main flaw is that the accumulation of around 1F 5.5V had spilled acid. was also in the same thing happened! ie it shows mute, but going into test mode, (having pressed the key "INPUT SELECTOR DOWN" and "POWER", the analog input works (but only in TEST). Any help? Thank you
