    Anker SoundCore 2 Bluetooth Speaker Turns Off After a Few Seconds (Possibly Firmware Issue?)
    by zklgfs
    Hi,

    I have an Anker SoundCore 2 (A3105) that I saved from the trash (well, I guess there's a reason why it was supposed to go into the trash...). The problem is that it always turns off after a few seconds (sometimes it stays on a bit longer, between 30 and 60 seconds, but it still turns off). The power light turns on and the bluetooth light starts blinking, but both abruptly turn off again. The "turn off sound" is still played after the lights turn off. Sometimes, it also loops the on-off cycle several times without me pressing any buttons. If I connect an AUX cable, music...

    Dynabook Satellite Pro C50D-B-100 - BIOS Issue, Black Screen
    by wizard13
    Hello everyone,

    I am experiencing a BIOS-related issue with my Dynabook Satellite Pro C50D-B-100. When I power on the laptop, the screen stays black, and there is no response from the system. I suspect a corrupted BIOS.

    I have checked the forum and the available documentation but could not find a solution specific to my issue.

    HANNSG Hi221 -- 2 secs to black feat. CCFL flicker & "burn" marks on power board
    by ttmi100x
    Greetings everyone,


    I have a HANNSG Hi221 monitor that exhibits two seconds to black issues (backlight goes off, display is still on as confirmed by shining a flashlight on it) with some additional oddities...


    The monitor failed on me with a standard "2 seconds to black" some time ago prompting me to initially replace most of the electrolytic capacitors (some of them were bulging/leaking).
    Things kinda sorta worked for a night, then the problem returned along with some flickering and "buzzing" noises.

    Upon closer inspection...

    LG 82UN8570AUD ~ TCON or PANEL?
    by kca
    Hello all ~

    Hope this finds you well. This LG 82UN8570AUD (April 2021 model) 4K UHD television has full audio capabilities but video is compromised / problematic.

    When I picked up this large LG tv it had a full black screen upon startup. Previous owner said it just went black one day. No popping sound or anything else of note.

    I got the display to work by taping off several traces of the right-hand side ribbon cable on the TCON that leads from TCON to PANEL. However, despite dozens and dozens of attempts to find the right combination / range of traces taped...

    For Badcaps Readers, Please note that I am hopefully going to present this same message to Lenovo to see if they have any insight to the matter as well and figured to share the entirety here for clarification. The System is out of warranty as it is but does have the option to have it extended.
