    Panasonic National NV-M3 VHS Camera shuts down after some seconds

    Hello everybody,
    First post here. I have been reading posts here for some time now, but today I made my first account and post.
    The same question is also posted on another site, here it is:

    Just found an old Panasonic National NV-M3 VHS Camera without the original charger but with a special bag with a led, switch and fuse that is designed for a lead-acid 12v 6Ah battery. It has two cables coming off the bag that leads to the camera terminals (Only + and - ). Pretty sturdy design I think.

    I tried connecting it to a Computer PSU (12.7v) but I get battery error and keeps turning off after some seconds. Sometimes the tape mechanism opens, but a tape is currently stuck there. I tried using a 13.5v power supply. Now, there is no battery error, but I get a lense error "WHITE, LIGHT" and turns off after some seconds. Is there a protection mechanism for the tape? I want to try every possible solution before I try replacing the caps. Also, I dont think it is a capacitor problem because it drops an error. Any help will be greatly appreciated.

    Thanks!

      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.

      I have a really weird problem, this motherboard was working normally, someday it just started and all fans were running but didn't want to post, tried resetting bios, checking CPU and it was getting warm tried external gpu, flashed bios with programmer, but same problem.
      Next day after several attempts the board goes into protection mode, no more staying on, I turn on the PSU fans starts directly turning, it used to not start until I press the pwr button, now it starts directly and fans spins, and shuts off after 3 seconds sometimes less, then won't start again unless I unplug the PSU and...

      ASUS B5402CEA – Laptop powers on for a few seconds then shuts down
      by riki_22
      Hi everyone,

      I’m working on an ASUS B5402CEA notebook.

      B5402CEA_MB_R2.2
      HA4YT LA-L861P
      REV:1B

      The board powers on, fan spins for a few seconds, then it shuts down by itself.
      I suspect the BIOS might be corrupted.

      Could someone please check and clean (repair) the attached BIOS dump?
      I’ve also attached a few photos of the motherboard for reference.

      Thanks in advance for your help!

      Sony LED 65X9005A shuts down after few seconds - looking for help
      by tec3000
      Hi community! Germany calling I am wondering if you guys can help me out. I have an issue with my Sony LED TV. I've been told this is a good place to ask. Thanks for anyone who will reply and offer advice. Appreciated!

      I have a KD-65X9005A Sony 4k LED TV. For a few weeks I've got this problem where I turn on the TV and within a few seconds the TV starts getting darker until it shuts itself off and I get the 4 blinking error code. HOWEVER there is one exception: Whenever I switch to the i-Manual, a full screen on-screen instruction manual, the TV never turns off. I tested for hours!...

      Lenovo L580 20LW-0010GE shuts down after a few seconds
      by solveit68
      Hello together,

      I am hoping for some tips here to repair a notebook.

      The notebook has following issue:
      After starting the notebook it shut down after a few seconds.
      Sometimes it is possible to enter the bios but then after, another few seconds it shuts down also.
      The time until shutdown varies slightly.

      What I've tried so far:
      - cmos cleared
      - removed all components that are not essential for motherboard testing including keyboard and touchpad
      - ram exchanged
      - same behaviour with power supply or battery...
