Request for Firmware or Help – Kenwood M-9000 SS stuck on "Waiting for PC Wizard"

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

Help Kenwood
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
KENWOOD KRC-194YG autórádió nem kapcsol be
Sziasztok Mesterek! Adott a címben szereplő autórádió (rajz a tanyán). Amikor bedugom a táp(stb.) csatlakozót, 2 másodpercre felvillannak az előlap fényei és megjelenik az "ALL OFF" felirat, majd teljes sötétség és néma csend. Innentől csak a reset gombra reagál. Ha ezt megnyomom, ismét felvillannak a fények, ua. a kiírás, aztán megint csend. A BackUp +5V megvan, de állandó jelleggel jelen van a PowerOn +5V, és a +8V is. Az én értelmezésemben utóbbi kettőnek csak bekapcsolt állapotban kellene megjönnie. Vagy rosszul gondolom? Mellesleg a BackUp +5V-ot kapcsoló tranyó olyan forró, hogy az ujjam 1mp-nél tovább nem bírja. (De a fesz megvan és stabil.) Próbáltam másik előlappal is, de azzal is ua. Végső esetben szerzek mégegy ilyen rádiót és összehasonlító méréseket végzek. De ez valszeg csak holnap lesz. Addig is minden ötletet szívesen vennék! Köszönettel: Gyula
