    Help identifying PCB FS-750-2025 with TEA2025 – unbranded multimedia speakers


    Hi everyone,
    I'm trying to identify the origin of a circuit board inside a pair of unbranded stereo active speakers. No logo, no model number—just generic "MULTIMEDIA SPEAKER SYSTEM" printed on the front.

    Main details:
    • PCB marked FS-750-2025 with a logo that looks like a stylized sail inside concentric circles
    • Audio chip: UTC TEA2025, stereo configuration
    • Potentiometers: B50K (Volume, Tone, Power)
    • Capacitors: 470µF 25V and 1000µF 25V
    • Transformer: 230V~ → 19V AC 350mA, thermal fuse rated 115°C
    • Speaker: 5W driver with magnet labeled “JY ม5w” (Thai characters)
    • Cables and plugs marked LU CHIANG, YI HUAN, KEMA KEUR, VDE, OVE

    What I'm looking for:
    • Identification of the PCB manufacturer or full system
    • Known commercial models using this layout
    • Anyone who's seen this logo before or has a matching schematic

    I have detailed photos of the PCB, transformer, wiring, speaker, plugs, and markings. I can upload them if needed.

    Thanks in advance to anyone who can help!

      Can anyone identify PCB logo?
      by smarty
      Can anyone identify logo shown below?
      The logo I showed can be found on the PCB's of laptops NP530U3B, NP530U3C, NP540U3B, NP540U3C, etc.

      I assume this is a logo of one of the PCB's manufacturers, but I'm not sure.
      Neither ChatGPT nor Copilot know the correct answer.
      TIA

      Hi, I have a few of these & they came with a custom bios boot logo, no passwords etc.

      2 x were brand new unused but with custom boot logo, 1 I installed Windows/ran updates then it bricked itself. 1 wouldn't get past the custom bios boot logo.

      The third I loaded windows, took a backup of the bios chip, then tried to flash several different clean bios's via programmer which all caused it to not boot. I tried to reflash the original bios both using clip & desoldering but...
