    Gardena lawnmowerrobot mainboard, short out battery
    by Stigsolbjerg
    hi again
    this time its a mainboard from a mowerrobot, when i connect battery it shorts it, so the bms shuts down battery.
    when take the mm in beepmode and measure from the positive to the negative battery terminal on the board it beeps shortly like 0,25 sec, and when i reverse the probes it beeps again shortly 0,25 sec.
    when i mesure on the cap thats missing in pic nr 2, the bottom solderpath goes to the negative, the upper one is 1,2 ohm to negative is this a short?

    hope Capleaker is still around

    Got a LG with color static frozen. Doesn't move just stays on this picture. I'd assume it's main board but I'm sure one of you has seen this before. Any data helps thanks...

    Sharp LC-40UG7252K black screen
    by Wodger
    Good day all,

    As title says, black screen. Replaced hot side and largest cold side capacitors on power board as were reading erratic and TV was dead (no power light).

    Following replacement, power led now illuminates, changes from red to blue on pressing TV joystick, still black screen. Connection board appears powered (optical sound led on). Slight crackling from speakers.

    Checking led driver voltage reveals voltage falls off after power on from pressing joystick (drops to zero).

    Attached picture of power board.

    Next check steps...

    Pioneer PN50951-22U Backlight On, No Image
    by x_orange90_x
    I get backlights that stay on not there is no image. The tv does not automatically power on when plugged in either which I generally see happen when there is a fault. It responds as it should to the power button.

    I checked the test points on the TCON and I have proper voltages except for at 1P15V. I don't know if that is supposed to be 15V or 5V, but either way I only get 1.134V on that point. I have 12V, 8V, VCC, and a small amount on the CKV point.

    I tried heating up the SoC on the main board but that made no difference. Disconnecting either ribbon from the TCON also...

    by felix27
    Hello,
    I want to fix a 2016 12 Inch Macbook which has a dead Logic Board.
    USB-C and Battery section seems to work, trackpad clicks, but all cpu Voltages, (VCORE, CPUSA) are 0V, CPU stays cold.
    PPBUS_G3H, 3.3V and 5V Rails seem normal. PM_SLP_S3_L is present but CPU_VR_READY is not.

    Thanks for your help!

    Hello guys, can someone help me with an eMMC dump for a Sony KDL55W-955B TV, I tried to read the original memory with the RT809H but it shows me that it only has 1888MB even though it should have around 3.8GB.

    KDL-65W955B, KDL-55W955B, KDL-60W855B, KDL-50W805B, KDL-42W705B, KDL-32W705B, KDL-48W605B, KDL-40W605B, KDL-60W605B, KDL-55W805B, KDL-42W805B, KDL-48W585B, KDL-32W706B, KDL-42W706B, KDL-42W815B, KDL-42W817B, KDL-50W815B, KDL-55W815B, KDL-42W828B, KDL-42W829B,...
