A címben szereplő Bluetooth-FM rádió-USB-hangszóróban lévő végfok IC típusát nem tudom leolvasni, mert megégett.
Hátha valaki látott már ilyet belülről és tud segíteni :)
Képek a készülékről és a panelről:
Nemrégiben készítettem 2 db quad 405 panelt (kapcsolási rajzot csatoltam), melyet eljutattam a megszólalásig. Az végfok panelok hűtőborda nélkül megfelelő teljesítményt és hangszínt produkáltak (járatásuk pár másodperc volt ügyeltem nehogy túlmelegedés következzen be borda nélkül.) Ám mikor végre hűtőbordára szereltem a T7,8,9,10-et furatszigeteléssel, csillámmal és hővezető pasztával, a hangteljesítmény lecsökkent és torz hang bántotta a fülemet. Reménykedem hogy segítséget kaphatok tőletek, előre is köszönöm!
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
