    LG OLED C1 Pixel Cleaning Made Picture Worse
    by rumi409
    ​​​​​​ Hi,

    I'm trying to resurrect a LG OLED C1 TV that has some panel banding. I used the TCON error bypass to get a picture. I was able to update the firmware as well. But when I performed a pixel cleaning to try to get the banding out, it made the image significantly worse. I tried to undo the effects of the pixel cleaning by performing a factory reset and IN_Stop, but that didn't work. Any way to reset pixel cleaning data?...

    what i went through dealing with my mobo with dead onboard sound!
    by ChaosLegionnaire
    so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!! what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol!

    Mobo MSI B550-A PRO password popup
    by Cerberuska
    Hello guys,
    I have interesting problem. My MoBo MSI running on Ryzen 7 w/o graphics just good. I swapped to Ryzen 5 5600G and on the boot I stuck with screen on picture. Enter Password. I checked BIOS setting with Ryzen 7, no security is enabled, BIOS password or TPM.
    BIOS I updated to last one.
    any suggestions?
    And same thing for two different 5600G, and yes, MoBo supposed to support it.
    Thank you...

    Macbook Dust-Gate Preventive Cleaning
    by howardc64
    Just did this on my 2021 13" MBP M1. Dust-Gate design flaw still present. Depending on cleanliness of the operation environment (often eating while using MB is probably the worst). Periodic cleaning is probably warranted.

    Note this is quite challenging effort. One misstep will damage the LCD flex and render it useless. So take it to someone more experienced if uncertain.

    Dell G3 17 3779 - no display after mobo replacement
    by mrsith
    Hi guys,

    I have a friend's Dell 3779 that came to me with severely shorted mobo. Did not manage to isolate the cause, most likely that was a bga shorted. Went for a replacement motherboard. Got one from China, apparently it's been tested prior to shipping. The mobo starts up normally but I am getting no display whatsoever.

    Tried using external monitor, but being blind I am not sure if laptops goes as far as booting to Windows, a d without it I cannot get hdmi to work. Can't see boot menu options to make sure it boots to Windows. Went ahead and did a blind bios update,...
