    Palit RTX 3060 Possessed fan .. Intermittant control
    by 90Ninety
    So I purchased a faulty GPU on ebay Palit RTX 3060 .. It had a broken fan ( it did not spin at all )

    Long story short , is the PWM control of the Card seems to be intermittantly faulty

    Long story
    I replaced said fan , seemed to work for a while , until randomly the fan starts spinning at 100% ( around 3.2K RPM ) for no rational reason ( temps and performance are ok ) . Now fan spins , though several times a day the fan decides to run at 100% for several minuites a time .. Then resumes normal operating ..

    bear in Mind the card can be cooled sufficiently...

    Samsung LH82QENELGC/EN Help needed - Static line on screen
    by Kiberge
    HI guys!

    I've got a Samsung LH82QENELGC/EN with a problem and need some advice and I hope this is the forum to use?
    I'm from Norway so I'd like to apology in advance if my description of the fault is kind of simple or the names on the components are way off. 😊

    the TV is powering up, working as normally and picture is all good, except a 1.5-inch-wide vertical line of snow/static across the screen.


    This TV is a Signage Display/Public Display version and it's been used at my work for 4-5 years showing commercials 24/7. The fault occurred when...

    by waterchill

    - replaced 343S00327 -> no result
    - replaced 343S00328 -> no result

    Help Identifying ASUS ROG Rapture GT-AXE16000 Board Components
    by kujoswrath
    Hi Everyone, hopefully somebody can help me.

    I have acquired an ASUS ROG Rapture GT-AXE16000 with a faulty 10GE port. It's locked at 100Mbps. A component on the board went pop but I'm not sure what it is. If anybody has a schematic or knows what the component is I'd be extremely grateful.

    I have attached pictures highlighting the thing that went pop.

    Any help is appreciated. Nothing else around it looks damaged and a quick check with my multimeter seems to confirm this. I tried taking one of its brothers off and measuring it but, when I tried to grab it with...

    How do you trim a BIOS file?
    by survivalbloke
    I downloaded a BIOS file from Lenovo and once I extracted the actual BIOS from the executable, it is 16MB in size, but my IC(Winbond 25Q80DV) is only 8MB in capacity. I have read you can trim the BIOS file with a hex editor but I can't find any instructions on specifically what you will remove.
