    Greetings all. Blew a cap off and don't know the value of it
    by Kurgan77
    I found a short on a mosfet in the vrm and used my air station to remove the bad component. and after viewed my work and noticed that had also blew the cap above it off as well... it went to cap heaven. I don't need the boardview file just what cap values are needed to replace the component. This is on a gigabyte r927xoc-4gd Windforce. I am a novice at repairing as that was a rookie mistake, + side is removal of the shirted package cleared up the short.

    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...

    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...

    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

    Modify BIOS to non-uefi
    by hexdy
    Hello, I wanted to know if it is possible to modify a BIOS file to accept a legacy disk when it does not have the capability, I had this problem on a Optiplex 3060 that were donated to my job where we use non-uefi linux distros, we cannot use uefi since is a "big machine" with this systems beign the center of all of it, we can't change the distro now, maybe make some changes, but if I can modify the BIOS it would be awesome.

    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?...

    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...
