    Apple Macbook Air M1 A2337 Trackpad problem
    by Skrndelj
    Hello all,

    I am repairing a Macbook A2337 and i have a problem
    The Macbook is stuck in restore as someone before me tried a DFU restore and bricked the device, now i can't do a restore as AC2 throws error 1 which is related to the trackpad.
    When i turn on the device i get the trackpad click for a few moments and then nothing, i tried 7 trackpads and 7 trackpad flats, i know all 7 are functioning okay, especially one as i use it for testing and DFU restore.
    I inspected the whole board and everything seems fine.
    Can anyone help me as i didn't fiddle with trackpad...

    [RoG Ally] Fault in one of the onboard RAM chips. Any way to diagnose which?
    by Prott
    Hello dear badcappers!

    The title pretty much says it all - do you, please, know if there's any way to troubleshoot which of the integrated RAM chips (LPDDR5X in this case) is faulty?

    [B]Backstory: [/B]
    After replacing the 4 onboard (soldered) memory chips on a RoG Ally (4x4 GB to 4x8 GB) it got stuck on the RoG logo. I assume one of the chips is either not soldered properly or faulty. However after reflowing and replacing bunch of them I am still stuck at the same place.

    If there is a way to narrow down which memory module is faulty it would make my...

    ATX power supply component identification.
    by unimatrix93
    Dear forum,

    I'm trying to fix up this faulty PC ATX PSU.

    ​​​​​​It's a FSP HP600S.
    [ATTACH=JSON]{"data-align":"none","data-size":"small","data-attachmentid":3288754}[/ATTACH]
    It's probably easier to buy a new one, but I don't want to throw it in to the trash and I want to try save it.

    There is two burned component (SOT-23) on the circuit, which marking is burned off. I need some help identifying it to replace them. And a burned smd resistor.

    Thank you!Dear forum,

    Sony XBR-52LX900 BL_ERR
    by Nicktronic
    Hi all, just curious if the BL_ERR signal is active high or low? TV has the 6 blink error code and I've changed the backlights as they tested questionable (4 strips tested - 203VDC, 203VDC, 203VDC and 175VDC). The new strips all tested at 175VDC. Now when I turn it on, it tries twice to come up and then the 6 blink code. During the this time the BL_ERR pin is high and drops low momentarily, then does it again on the 2nd try to boot (so Im assuming active low). The other thing is the backlight voltage ramps to ~280VDC from around ~160VDC and then back down as the TV tries to boot again. Does...
