    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...

    Vestel tv, how to flip the image?
    by France_53
    Hello everyone from Italy, I'm here to ask for help on a Vestel TV, I've had a Vestel TV branded "XD" with a broken screen for years, but now I've found a Telefunken (still Vestel but older) and I've mounted the panel on the "XD" TV, it works, but the screen is upside down, given that Vestel does not allow you to rotate the image from the service menu, does anyone know how to solve the problem? the original panel is marked ves315WNDS-2D-N12 while the main board 17mb110, the panel I mounted instead in the tv (from the telefunken) is a ves315WNDA-02. ... It is not worth repairing...

    there is no reaction, it hangs at 20 V/0A. There was a little corrosion in the u7650 area. Replacing the u7000 did not help. Tell me, what else could it be? PPBUS_G3H=12.9V
    Flashing the bios with a clean region also did not work!

    by hotgly
    After upgrading the factory 128Gb SSD to a 512Gb WD_Black SN770M, this surface pro lost touch on screen, no touch in windows or in UEFI.
    The Human Interface Devices did find touch and stylus but it shows Disabled in windows device manager.
    I am not sure if this is a bios problem or hardware problem, already tried reinstall and reset from windows, not working. And now trying to clean/reset the bios.

    ASUS GA401QM No ACDRV, No CMSRC
    by ResoluteHawk
    I have an Asus G14 (GA401QM) that has a power issue. Originally the board had a shorted 5V rail and dead EC. I reballed a working EC, soldered it on, and I resolved the 5V issue by replacing the APL6012 and the low side 5V mosfet. Resistances on all power rails are healthy now, but 20V does not make it through the first MOSFET. 20V is present on the drain of the first MOSFET, but there is no voltage on the gate or source.

    When diagnosing this issue, I thought that the issue was due to the BQ24800 chip not outputting the correct signals so I soldered on a known working chip and the...

    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

    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.

    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 fileโ€‹

    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?...

    Lenovo LA-K321P two "bios" chip
    by jasko_jacker
    This motherboard has two chips one is UC4 -> 16MB which contains the main bios without the me inside, in fact if
    use ME analyzer to check, it returns (see pics) "file does not contain intel engine/graphics/indipendent firmaware".
    The second chip is UC2 -> 8MB, it contains ME data (see pics) and other things like PMC. If there are problems
    like power management or ME, the chip to be rebuilt is UC4 and not UC2. Anyone confirm this?
    I unzipped the exe file via this guide on the official Lenovo website

    When plugged in (no battery installed), the battery light on the motherboard lights up and then turn off. When powering on, the same and light and the power button also light up in a white color but no output on the display. It stayed like that for a few seconds before shutting down. I also seem to ruined a connector that connects to the WLAN, 2 USB and audio board, the same board also have a melted 2062A IC. I will post pictures in the reply section
