    820-01949 - A2337 - Quick Fan Spin for a Few Seconds. Charging and Main Rails OK
    by willis6732
    Hello,

    This macbook wont turn on. Only a quick fan spin. Sometimes fans spin a few second. Somtimes they spin fast for a few seconds. Other than that no signs of life

    All the Coils on the board have voltage and battery charges fine as well.

    I noticed this not sure if it is suspicious:
    PPVCC_CPU_PH1 / CPUCORE_SW1 = 40 Ohms (Flex Bv shows 90 Ohms)
    =.023 Diode Mode (Flex BV shows .090)

    I would appreciate som support in the diagnosis.

    Equipment Display Types
    by Mark R
    Most Displays I have worked with are of course LCD Or Blueish Fluorescent Types. I Have a Marantz PMD800 tuner with sort of a white display. The display area is a sealed rectangular shape in a Glass Case. Looks like some sort L.E.D. display only not your typical section number type. I picked up this Tuner cheap as the display is very Dim. In front of the circuit is a dull red Plastic lens.

    The display is very week and hard to see. I've got my DC 5 Volts allover and also a DC 32 Volt that runs some other section. Power supply looks good front to back. Not familiar with this type...

    Lenovo m80s gen3
    by CedH1
    Hello,

    I'm a total beginner about bios, chip etc.
    I tried to make some search, but it's pretty difficult to have a good understanding about this.

    I have a Lenovo m80s gen 3, with a forgotten bios password.

    From what I've seen, I have 2 chips on the motherboard, on the bios_rom 1, I have this written on : mxic x224727 mx25l25673gz41-08g


    I would appreciate some help about this :

    1) is it possible to get rid about the password in my case (any method) ?
    2) what kind of materiel should I buy to be able to dump this...

    Samsung WD80N645OOW died mid-cycle
    by mrsith
    Hi fellow lifesavers.

    I have a Samsung washer-dryer WD80N645OOW which died mid-cycle. No response to anything, completely dead.

    Checked the socket, the plug fuse, all good. Took it out to examine the boards.

    There is a relay clicking on the mainboard. Upon applying power, I can see a diode flashing on inverter board, after a while a diode on main board lits up for a split second, then I can hear a relay clicking. This repeats a few times, then everything dies completely.

    I've been trying to examine the main board, but it's a bit difficult becuse...

    A1707 820-0098 5V power loop all USB-C except one jack, and strangeness after replacing the one bad CD3215C.
    by abajor
    I have this 1707 with the 5V 0A power loop issue on 3 of the jacks.
    One of the CD3215C00 had corrosion under one side U3100 to be precise.
    This USB jack was drawing ~.2A and not boot looping.

    After replacing the CD3215 I am having an odd problem. I can rotate the USB-C and it only works in one orientation. And now it boot cycles, like the other usb channels so I'm part way there.

    After looking at the schematic and board view. It makes very little sense that this is happening since they both pin 59 and pin 60 both go to the same places on J3300.

    NO BODY MARKING Diode
    by dennis_elx33
    Hello Everyone,
    I have 1 diode on a circuit that I suspected to be faulty because the forward and reverse bias has a voltage drop reading.
    While compared to the reading of another diode from the next channel it won't read at reverse bias.
    Now the problem is; it does not have any body marking.
    So I tried to sketch the diagram and found out that it is connected to the base and collector of the C3632 transistor.
    What do you think is this diode?
    Can you please suggest what part number can i use to replace this faulty diode instead?

    Hoping that you...

    MacBook Pro M1 A2338 256/16 820-2020 Turns On but No Charge, stuck 5V
    by Daniel M
    Hello all,

    I bought this MacBook brand new at launch. I have taken care of it since new and it suddenly failed on me recently.. it began to refuse to charge.

    I first checked all the basic things before opening it, to no avail.

    I have now opened it and taken the logic board out. I did a visual inspection and found no visible liquid damage or corrosion, or exploded caps, burnt components, etc. Cleaned the usb c connectors.

    Here are my measurements thus far:



    PBBUS_AON: 12V

    PP5V_S2: 5.3V

    Unable to extract bios file from Lenovo bios exectuable
    by survivalbloke
    I'm trying to extract a flashable bios file(ch341a) from the lenovo bios executable download. I have tried the instructions from this site [URL]https://starkeblog.com/lenovo/uefi/2022/08/28/extracting-bios-image-from-lenovo-update-exe.html[/URL], which are not working. According to those instructions, after issuing the command [CODE]"innoextract 7wcn38ww.exe"[/CODE] it should create an \app folder, inside which, I should find a newly created "7wcn38ww.exe" file. I should then be able to extract that using 7zip and find my .FD file.

    Uni-Sync Model 50
    by Logistics
    Good morning, friends! I saw an old, heat-sink-heavy unit on craigslist yesterday, so I decided to snag it as the owner only wanted $25. He says that one side powers up normally (lights up green), but the other side stays in clipping mode (lights up red). I haven't opened it up, yet. However, I'll post a picture of the guts from another owners unit so you can see what they look like inside. Looks pretty simplistic as it's all single-sided boards and through-hole components. What I am gleaning from my research is the first thing that should be done is the replacement of the large stiffening...
