Hi everyone,
I'm currently working on reviving a Yatour YT-M06 CD Changer Emulator module for use with a Pioneer 1 interface (specifically with a DEH-P5950IB head unit).
While the unit is recognized as a CD changer, none of the USB, SD, or AUX features respond, which leads me to believe the firmware may be corrupted or incompatible.
🔧 Details:- Model: YT-M06
- Interface: Pioneer 1
- MCU: Fujitsu MB89F202
- Goal: Find a valid .bin firmware file or memory dump from a working unit
I'm happy to attempt flashing, analyzing memory dumps, or doing hardware-level...07-15-2025, 12:26 AM -
Hi everyone,
I'm currently working on repairing a Yatour YT-M06 multimedia interface (used with Pioneer head units). I'm looking for the firmware or schematic diagram to troubleshoot the board, as it's currently unresponsive.
If anyone has any documentation, tips, or experience with this specific unit, I'd appreciate any help!
Thanks in advance,

I have not been able to locate a service manual for this Pioneer SX-S30 receiver. The unit will not turn on. I am troubleshooting the switch mode power supply. I found three smd semiconductors that test open while in circuit. The first (Q904) is a transistor marked AZ43W. The second is a diode D905 marked L68 and the last is a diode D906 marked 66 CU1M. I have attached photos.
Any help would be appreciated. Thank you.... -
Hello everyone. Could anyone please share the service manual for the LG 38GL950G monitor? I have been using it for four years and just noticed that the PCB fan has never worked. The self-test also shows an error. It would be great if I could repair it somehow.12-01-2024, 07:20 PM
