    TDK ZWS150BAF-12
    by Keshenatech1
    Does anyone have a schematic or parts list for a ZWS150BAF-12 12V power supply? I have a dead one and I've determined the surface mount diode on the back side of the board that connects from the center leg of Q3 to the + side of the 420V 60uf capacitors has a 3.5 ohm short. I'm not having much luck trying to identify the diode as the part number is not very legible. In the attached picture, it's the black rectangular diode in the center. There are some numbers on it but I can't even tell if it's right side up or upside down. The picture is from a 2nd good working unit which is more legible...

    LG 43LH510V Backlight problem
    by unimatrix93
    Hello everyone,

    I'm trying to fix a small LG TV with wierd issue.

    So I check that the display is OK by fashing a lamp at the screen. LCD is okay OSD is showing up.
    Now since the BL is dark, I disconneted the BL from the mainboard and I injected voltage to it with my blacklight tester.
    The BL turns on, the tester shows around 80V. So the led strips are okay it seems.

    Now I started to suspect the BL driver IC which is a MP3378.
    I have a donor board (dead cpu) with the same IC, so I swapped the driver IC but it did not solve the issue.

    Surface Pro 6 with no USB
    by MBaads
    Hey friends.

    I bought a used Microsoft Surface Pro 6 . Good condition, only downside is that the xHCI complient USB Host Controller gives code 10.
    I have tried everything that seemed immediately obvious to solve this, like driver updates, roll back OS versions, run all MS's diagnostics tools etc.

    The kicker: It works in UEFI just fine.
    It works in Grub2, too.
    I can even boot off a USB recovery drive thumbstick. However, after it has loaded the image and starts the OSs drivers, it fails.

    Lenovo legion y540 adapter pin id
    by TheOtherGuy
    So I'm having difficulty finding line drawings for this motherboard NM-C53. My charging port was broken. So I replaced it with a terrible solder job. Problem is pin 3 on the drawing I saw on here has it listed as adapter-id. Now I checked my other pins and I have continuity (resistance check from power to ground). Pin 3 shows nothing. Now I boot the computer and it says to use a power adapter with the proper wattage and won't charge. I have read that pin 3 is usually tied to a resistor that identifies the charging power thus disabled the ability to charge if it fails the check. I look at my board...

    by Darren Hibbert
    Hi.

    My Hp G6 laptop died while using it.

    I opened it up and used a thermal camera on it to see if anything was getting hot. The RT9513 chip (EQ ED B1Y) which is supposedly a battery charger ic was getting hot. I ordered a new one and replaced it but its still red hot. Where should I look next?
