    Identifying component Flyback? DC-DC?
    by unimatrix93
    Can I ask you guys help me identify this godforsaken component?

    I'm tearing my hair out finding this component.

    The board is from an egg incubator.
    i got it with a "popped cap" while there are many damaged components on it, which got succesfully identified with one exception:

    Yamaha stagepass 500
    by gbaicu51
    Hi all,
    Looking for advice please, regarding those 2( film capacitor?? - honestly not too confident if are film capacitors). Short version of story : I bought a stagepass 500 active speakers, and found those components nearly blown. I know they are 1= L 125. Any advice where I could find them to buy, and also what else could lead to this fault?( I have a multimeter and soldering iron and I can get fixed if someone could give me some instructions)
    Thanks all

    Gigabyte GTX 1080 G1 Gaming voltage present but not detected
    by Traptor
    Hi guys,
    I have a Gigabyte GTX 1080 G1 Gaming 8GB gpu. The earlier life of this gpu is unknown.

    Fans are spinning on full speed.
    All main voltages presents but gpu not detected by motherboard.
    The voltage on pin 1 of the bios is constantly 1.8V

    During visual inspection i noticed a brown spot on the top of the chip.
    Maybe burned this GPU?

    Does anyone have an idea where I should go next?
    How do I check if the GPU is still alive?

    Tv Philips 55PUS6031 no image, backlight ok
    by Raulnn
    good night! I have this TV, with quite poor build quality. It has a tcon integrated into the panel, a single flex from the tcon to the panel, and the 2 panel controller boards joined by glued flexes. There is no way to separate them.

    The symptom is that the image is not visible, but the backlight works. How to know if the problem is in the main or in the tcon-panel? I can't override zones.

    Lenovo Ideapad 320-15ikb: Comes on and goes off
    by Nagyesz
    Hey guys, I have a Lenovo Ideapad 320-15ikb NM-B241 rev:1.0.
    After turning it on, it runs for a few seconds then shuts off completely. No screen, no fan. After shutdown, a red light comes on and off fast. I've been trying to troubleshoot this for days now. It's never been opened up; the Lenovo sticker is still intact.

    (!)I tried with a different BIOS battery, without any ribbon cables, on battery power, without the keyboard, and it's always the same.

    Any insights on what might be causing this?...

    Samsung LED UHD TV - Bad Main Board or Bad T-Con Board? Pictures inside
    by E--Man
    Hi All,

    Thanks for reading. Based on the interesting fact that the vertical lines issue don't seem to effect the menus whatsoever but rather everything around the menu regardless of video is shown, I'm trying to set mine whether the issue is the main board or the t-con board.

    Again what's baffling is that the menu is not effected whatsoever. However, any other video displayed regardless of inputs or when no inputs exist exhibits the vertical lines and seem to effect black areas only.

    The lines are green in color when the tv is in "Game Mode" and...

    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!...

    Samsung QE50Q60TAU - Horizontal screen lines
    by Runlinc
    Hi everyone, the tv was in a continuous reboot cycle. To get the best screen image i can I taped the VGH and VSS pins on the left side buffer board joining ribbon.

    I am left with a good image apart from the black horizontal lines that I cannot get rid of.

    I cannot find anything on the buffer boards that has shorted.

    Do you think there is anything i can do to eliminate the lines, or are they caused by an internal panel short and the image cannot be impoved.

    Many thanks for your assistance

    A1706 Won't Turn on 20V/0.3A draw
    by fharris1977
    I have a MacBook Pro Touchbar A1706 that won't turn on. With the board removed I'm getting 19.62V and an average amp draw of 0.300A. When I first plug in my ampmeter it goes from 5V to 19.62V after a second or 2 and the amp draw starts at about 0.688A and up to about 0.790A and then it gradually goes down to about 0.155A and works it way up to around 0.330A and then it fluctuates in the range of about 0.200A-0.350A. The voltage stays at 19.62V. Can someone with any experience with this issue help me out. I checked all the main power rails and they were present. Anyone know it would be greatly...

    MacBook Air 13 2014 - Remove EFI password
    by ritalo
    Hello,

    I have a MacBook Air 13 inches 2014.

    I have set a EFI password and I can't remember it : now I want to reinstall macOS and I can't because the MacBook is asking for the password.

    I know how to remove the password with a usb programmer.
    I plug the usb programmer to the motherboard and to my pc with usb, I read the EFI and I save it to a file.

    Then I have to find this value in the file : $SVS because it indicate where is the password.

    But I can't find the value.

    I have attached the file​

    Thank...
