          Rather, the problem is in the set-top box itself, if you manually start it and 12 v appear, if there is a problem with the set-top box, then it blocks these 12v.

                      PS4 pro PSU (ADP-300FR) shuts down when turning on 12V
                      by Norrecito
                      Hello all,

                      I would like to ask for your help to troubleshoot a faulty PS4 pro power supply (ADP-300FR).

                      A couple of weeks ago, I've picked up a PS4 Pro (CUH-7216B) from one of the local flee markets. According to the seller, it has a "no power" issue and the PSU is most likely faulty. Based on the cracks on the housing, it was probably dropped.

                      Tried it at home and sure enough, it had a "no power" issue. (Pressing either the power or eject buttons had no effect).

                      I took out the PSU and opened it. Immediately noticed...

                      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:
                      1. I

                      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...
