    Pioneer SC-LX56 & 86

    I recently acquired 2 x faulty Pioneer AVRs, a SC-LX56 and SC-LX86. The 56 was UE22 no audio and the 86 was in DC protect flashing the MCACC LED.

    I've fixed both these issues and they both work but after a few days use, both exhibit the same fault which can only be cured by a factory reset. They become slow to respond to front panel and remote controls and eventually freeze up altogether.

    After a full reset, both work fine again. I've installed the latest firmware from Pioneer with no improvement. I'm starting to think there may be a problem with one or more of the flash memory chips, in particular the 1Gb NAND flash but I can't find any info on this problem.

    Anyone encountered this issue before and found a fix?

    Pioneer VSX-1021 MCACC flashing, can't find problem
    by burntonnerings
    Have a Pioneer VSX-1021 that goes to MCACC flashing as soon as it is plugged in.

    If I enter release mode, it powers on, the screen display is correct, but then it shuts down and goes back to MCACC after a few seconds. I can shut it down to standby (w/o flashing MCACC if I hit the power button as soon as release mode finishes the boot sequence).

    Entering reset mode and executing a reset doesn't change this.

    I am unable to enter service mode to see the error counts - Enter + Power button doesn't do anything, whether from normal standby or from MCACC flashing....

    Pioneer PL-X9 motor speed control wobble
    by Bushcat
    I'm starting to re-cap a Pioneer PL-X9 turntable, specifically the motor control board, because although everything tests out OK according to the service manual, the speed wavers slightly despite the quartz lock light remaining on. So, I've decided to re-cap that board since it's the cheapest next step...

    Pioneer's passive component naming convention is clear to me. For example, CSZA R22M 35 is tantalum, radial leads, 0.22uF, 20%, 35V.

    BUT there are two capacitors on the board which have actual Pioneer part numbers: PCL-042. I can tell they are 0.1uF, 16V but don't...

    [Help Needed] Yatour YT-M06 (Pioneer 1) – Firmware or Schematic Request
    by EduCabral
    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...

    Pioneer Kuro Pro 111FD 8 red blink error
    by pixelcap
    Pioneer Kuro Pro 111FD 8 blink red LED.





    I have been trying to solve the power-down 8-blink red LED problem with my Pioneer.


    So far I have replaced the power supply board, and the digital assembly board, I have reconnected the ribbons to all boards, ensuring the connections are good. Even though the problem is the 8 red light error and not the more common 8 blue light error code, I had Kcrownie,
    based in North Carolina replace the chips that cause the 8 blue LED problem (the main board and audio board) the plasma is still powering...

    Pioneer VSX-44 receiver HDMI dropouts
    by RatherLoopy
    I have an older Pioneer receiver (VSX-44) that's been dropping the HDMI output (black screen) for a few seconds every few minutes. Setup is HTPC -> Pioneer DVD HCMI in -> Pioneer HDMI out -> Samsung TV HDMI in, all with cheap HDMI cables that have never caused trouble before..

    I initially found a lot of play in the receiver's HDMI inputs and output so I kind of squeezed them back into shape and they're making a tighter connection, but the problem persists.

    And also, often, the HDMI will drop out in exactly the same way (black screen) just as my central air...
