    Samsung UE55H8000SZ with TCON BN41-02112A
    by michdundee
    Hi all,
    I'm facing a issue... hope you could help me. I have a T-CON board BN41-02112A from Samsung 55inch Curve TV.
    I have just only 2 status blue LEDs ON since LED3 is off. I have tried to test some test points but VON is NOT OK very close to 0V. Is there someone that can help me on the debugging the issue? I'm supplying the board from an external 12V voltage source. ​
    Thank you in advance.
    BR,
    Michele

    820-00165 Random green light on charger
    by ahoonid
    Hey everyone,

    I have a MacBook Air 2017 with a weird problem. The MacBook was totally dead at first and the culprit was the C7430 capacitor which was obvious upon initial inspection as it had a fracture on its surface.

    The F7140 fuse was also blown so I changed them both. L7130 due to corrosion was also replaced. Now everything works again. Laptops turns on and everything seems reliable at this point.

    The only issue that I'm afraid might bite me in the ass later is the magsafe light as it randomly changes light from orange to green while charging. Other times...

    my Xiaomi Notebook Pro X laptop fans work like crazy for no reason
    by sda sad
    Hope this is the right place, someone can help me.
    My laptop started having a really strange problem....
    When I turn it on the fans start working at a crazy rate and with random breaks...
    They can work for say 10 seconds and stop for 2 seconds and then turn on again for 5 etc...
    And it's from 0 to 100%. I tried to install AIDA and did the processor chip test and the graphics did not exceed 70 degrees and the fans were not even close to working at the power they work randomly.

    The model of the computer:
    Xiaomi Notebook Pro X 15 OLED (A30)

    Sony LED 65X9005A shuts down after few seconds - looking for help
    by tec3000
    Hi community! Germany calling I am wondering if you guys can help me out. I have an issue with my Sony LED TV. I've been told this is a good place to ask. Thanks for anyone who will reply and offer advice. Appreciated!

    I have a KD-65X9005A Sony 4k LED TV. For a few weeks I've got this problem where I turn on the TV and within a few seconds the TV starts getting darker until it shuts itself off and I get the 4 blinking error code. HOWEVER there is one exception: Whenever I switch to the i-Manual, a full screen on-screen instruction manual, the TV never turns off. I tested for hours!...

    Asus Rog GL703G/Battery Connector Short
    by GlassMonolith
    Hi, all. I have an Asus Rog Strix GL703G. Yesterday I took it apart to clean out the dust and redo the thermal. Unfortunately, when I attempted to pull the battery, the metal retaining clip (unable to retain itself due to genius engineering) popped off and shorted across the capacitors behind it. Now I have no response from the laptop with or without the battery.

    I'm hoping maybe someone can help me read the board and figure out what potentially shorted. I have a soldering station, I can run hot air, I have a multimeter, I just have no idea how to trace or measure the power circuit....

    INSPIRON 5570 bios maddeningly slow
    by Txus3232
    hi guys, i have dell inspiron 5570 with a maddeningly slow bios.
    specs are: service tag 6MSTDP2 CAL50/DAL10 LA-F115P REV: 1.0(A00) CORE I5 with radeon graphics
    When I turn on the computer it takes approximately 5 to 10 minutes to boot Windows, sometimes up to 15 minutes.
    That slowness is visible even within the bios menu. It seems as if the clock frequency has been reduced drastically
    I already tried some dumps that are in this magnificent forum, I also followed the tutorial by mr [B][URL="https://www.badcaps.net/member/237374-smdflea"]SMDFlea[/URL][/B]​ to...
