    Nikon D800 camera - flash don’t work and capacitor don’t charge
    by corrize
    Hello, I'm stuck in troubleshooting…
    The flash system works like that : when the (mechanic) flash button is pressed, the flash mecanically pop up, and a circuit buck boost elevate 7v (batt) to 200-300v (?) for charging the big capacitor. And when the photo shoot button is pressed, the capacitor is discharged in the xeon light.

    In the D800, there is a first « power board » close to the battery. 2 wires (batt 7v) goes to another little « flash board ». I measured 7v, so ok.
    When I press the flash button, it's detected by the system, flash icon appear on LDC display....

    [Help] Lenovo Yoga Slim 7-14ARE05 (DA0LS3MBAF0) – 25Q80DVN1G Flash Is All FF, USB-C PD Stuck at 5V
    by ekozeko333
    Hi all,
    I’m trying to recover a Lenovo Yoga Slim 7-14ARE05 with board DA0LS3MBAF0 Rev:F. I’ve run into an unusual issue where USB-C PD is stuck at 4.7–5V and the system won’t boot (keyboard lights flash briefly, then nothing).
    🔥 The Problem Started After Suspected ESD/PD Fault
    I experienced a power issue or ESD event through a USB-C charger
    After that, the NX20P5090 power switch was visibly burned and was replaced
    Now the PD controller always negotiates 5V @ 2A, even with known-good chargers
    🧠 What I’ve Done So Far
    Flashed...

    Canon VIXIA HF S10 A read data from inernal flash memory.
    by abajor
    Hello I've had somebody bring in one of these charming little cameras to attempt retrieving data from the internal 32GB flash.
    Something is damaged inside the cameras lens assembly I can hear it clunking around and it has probably dislodged the sensor, powering up the camera gives a blank screen and the focus motor sounds like it's having a fit.
    The camera will not connect to a computer via USB in this state, I have no options no navigation, just power up and focus/zoom motor noises.

    I think my best shot is to figure out a way to read the internal flash memory outside...

    Lenovo Legion 5 (15ITH6H) kind of boot loop but not sure
    by Stefano Crivellari
    Hi, I wonder if anyone can help me fix my Lenovo Legion 5 (15ITH6H) laptop. Basically, after a windows update the computer would not boot anymore. When powering on the laptop the screen has no backlight and nothing would show up, using an external monitor did not help. However, the laptop would still spin up the fans and turn on the keyboard backlight. The keyboard backlight intensity function key would work and the power button led and the charging led are also working. I've tried every possible combination of key press and power button hold down time but did not change anything. At this point...
