    ACER BM320 Monitor - Horizonal Flickering Lines After a While
    by reessi
    Hello,

    The monitor started off showing flickering thin (1 pixel) lines horizontally every say 3mm..

    They are black on the right and gradually fade to nothing on the far left.
    They start either after 5 mins or up to 2 hours after so annoying for testing.
    They flicker continuously very fast! With a slight pause milli-second every second.

    Initially I cleaned the LVDS cable and connected to the T-Con and then it worked fine for 3 weeks but not sure if this was just co-incidence.

    I tested each half by removing the first the left flex from...

    MSI GL75 9 Se Nvidia GPU code 43
    by totoFR37
    Hello guys.

    I own an MSI GL75 (i7)
    Motherboard : 17E51
    GPU : Nvidia 2060 RTX

    I spent weeks to install and clean the drivers but still have an code 43 and the Nvidia GPU not working.
    When using the GPU-z the GPU is recognized but there is no clock frequency.
    Seems the problem is from the hardware.

    What do you advice me to check ?

    Thanks

    Thinkpad L15 Gen 1 freeze on battery
    by tomodachi
    [B]ThinkPad L15 Gen 1 with AMD Processor
    Motherboard code : NM-C741 REV: 1.0[/B]

    The laptop works flawlessly when connected to an AC power source, and the battery is in very good condition (30 cycles, original battery).
    However, when the adapter is unplugged, the system freezes within approximately 20–30 seconds and becomes completely unresponsive. Sometimes, this is followed by a blue screen with the error code "DPC_WATCHDOG_VIOLATION".
    Sometimes it restart itself and sometimes screen goes blank..
    Here's what I've tried so far to resolve the issue:[LIST][*]CPU

    BIOS update wont complete - Dell Latitude 7420
    by Julian Bailey
    Hi all

    Anyone come across this issue where a BIOS flash will only part complete?

    It will update the system BIOS and Primary EC BIOS fine but fails to update the Intel TBT Retimer, Intel TBT Retimer 2 and ME Firmware.

    NVMe m.2 drive isnt detected in the BIOS, but you can get into the BIOS fine and it all works in there as intended.

    The drive works fine in another laptop.

    Link to a video I made of what its doing here:

    Any ideas on how to overcome this?

    microwave rotary switch contacts go bad requently
    by jm1234
    Hi, I have a 11 year old microwave Siemens and the main function selector switch is a rotary type. It goes bad every few months, there are carbon (?) pads and the metal contacts that drive on them create concentric circle tracks from the residue.

    I clean the tracks and the metal contacts with IPA and it works few months again. Here you can see the contacts:

    Hi all,

    Need some help identifying a component with the marking "PH2" belonging to a QNAP TS-231K with motherboard model QY42 REV 5.0.
    It's supposed to send 12 volt to the main circuit but only send 3.52Volts. If i bypass the 12 volts directly the motherboard powers up, but no boot.

    Gigabyte B450I AORUS PRO WIFI BIOS flash
    by unimatrix93
    Hello everyone,

    I bought a used ITX motherboard with a no display/POST and spinning fans. Original owner tried to update the BIOS and since then it's doing this. So something went wrong with BIOS update I assume.

    I have a CH341a programmer and I did repair motherboards with it before.

    Now I got the BIOS file from Gigabyte's site, but it's in a archive (F66g) or something and I don't know how to extract the bin from it.



    How should I proceed with it?
    Thank you!

    Dell Inspiron 7568 not turning on? Boardview anyone?
    by roxboy1984
    Hi,


    Does anyone possibly have the boardview file for this board. I have the Schematic already.
    The IC labeled "53A8" is getting extremely hot. This seems to be a 5V voltage regulator.

    Jeep Drive-train control module repair
    by unimatrix93
    Dear forum,

    My father's Jeep has this annoying rattling sound which is caused by the Drive train module as it constantly moving a solenoid.

    It comes and goes as the temperature changes. For example, when you cold start the vehicle from a long parking time, it starts loudly (especially on winter) then it goes silent as the vehicle's temperature rises.

    So I took the DTCM apart and found this damaged ceramic cap, which I should replace:
