    Aiwa MX-Z9400M

    hi guys I have the above hifi

    and after many trouble free years its now having an issue.

    where as sometimes there is a bang from the speakers and the unit shuts off,

    upon powering it on again its as if its reset its self and is in demo mode.

    I have noticed that if I tap the power amp section the sound cuts out and it shuts off.

    any ideas where to begin ?

    or has anyone got the service manual ?

    thanks

      Lenovo V15-IIL motherboard swap (in V15-IKB) shuts down when internal display is connected
      by Giggle2562
      Hello everyone,

      I have a Lenovo V15-IKB that had a damaged motherboard. I replaced it with a motherboard from a Lenovo V15-IIL.

      The board powers on, but it shuts down after about 10-15 seconds. This only happens when the internal display (LCD panel) is connected.

      Here's what I've tried so far:
      • When the internal display is disconnected, the laptop works perfectly fine via HDMI.
      • The laptop shows an image on the internal display for a few seconds before it shuts down.
      • I tried swapping the LCD panel with a known good one.
      • I tried swapping the LCD cable

      Lenovo Legion Slim 5 16APH8 (RTX 4070) - Turns on for a few seconds then shuts off. BIOS issue.
      by riko 656
      Hello everyone,
      I need help with my Lenovo Legion laptop. It turns on for a few seconds and then immediately shuts down. I believe this is a BIOS corruption issue.
      Laptop Model:
      • Model: Lenovo Legion Slim 5 16APH8
      • GPU: NVIDIA GeForce RTX 4070
      • Main BIOS chip size: 32MB
      • VBIOS chip size: 16MB
      Problem Description: The laptop was working perfectly. Now, when I press the power button, the keyboard lights up and the laptop powers on for just a few seconds, then it shuts itself off completely. After researching, I am convinced it's a corrupt BIOS.
      What I Have Tried So Far:

      ASUS FX505GD shuts off after POST — no BIOS, power button unresponsive
      by brav1ez
      Hello everyone,
      I have an ASUS TUF Gaming FX505GD that's powering on, showing the ASUS logo for about 2 seconds with keyboard backlight, then immediately shuts off. After it shuts down, the power button does nothing until I unplug the laptop completely. No fans spin afterward either.

      I’ve tried:
      - CMOS reset
      - Removing the SSD/HDD
      - Reseating RAM (removing each stick individually stops boot completely)
      - Cleaning up recently applied thermal paste around CPU/GPU and nearby VRM components (issue persists)

      With...
