    HP Elitebook 650 G9 Bios password reset needed
    by ShadXo
    Hi everyone,

    I have a HP Elitebook 650 G9, where I made a dump.
    I found on the internet that I need to edit the EC Bios. Something starting from Active till blank rows, which worked for a 840 G8 the guy was using, but didn't work for mine kept getting the 903-Computer Cover error.
    It was worth a try and now i'm also stuck here after the 903 error it goes to the screen to enter the admin password.

    I wonder if someone can help me with the edit of the dumps...

    Vizio V585-J01 dancing lines and image doubling
    by x_orange90_x
    I got this tv yesterday and it shows a screen full of colored vertical bars and horizontal lines that move, change, and dance around. When the set is powered on there is a slight buzz from the tcon. I removed one ribbon at a time and this was the result:

    Right side connected, left side disconnected = half image on right (somewhat distorted, see photo attached) white screen on left. NO buzzing from TCON

    Left side connected, right side disconnected = right side black, left side white with distorted horizontal lines near top of screen. Buzzing from TCON

    macbook A2918, orange light off when shut off
    by mosfetratus
    When i fully shut off mac, orange light goes off and wont react to power button. I have difficult time resetting with combination "shift+control+option and power button", because it rarely works (reason unknown), when i manage to get orange light and then press power button macbook wont turn on and orange light goes off. When i hold combination with power button it turns on, and works fine if put it to sleep mode.

    Works with battery and charges, but when i shut off i get this problem.

    It had liquid spill. Board has no corrosion, keyboard is working, power button...

    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...

    hello everyone
    I have a board that does not turn on and I found this integrated damaged but I cannot find the part number, I looked for a schematic but there is none. What I could see with the microscope is that it has these letters "THDN BCD" but I couldn't find any information, I'm sorry for the quality of the photo but my cell phone can't handle it anymore. thanks​

    BIOS for Lenovo Legion 5 15IMH05H
    by greenchigo
    Hello, please help:

    After replacing motheboard i need to transfer DMI data (Product Name, MTM, etc) from old bios backup to a new EFCN59WW for flash it by CH341A
    Everything is works but in BIOS and in Legion Vantage software s/n and others are INVALID for now. So... I want to flash and fix it.

    Also question is:
    Does I need clean ME or something else or I just can "copy-paste" offset 00532000-00533FFF from backup bin file to current dump bin file and than flash it to chip or... not?

    Corsair RM650 ATX, possibly struck by lightning
    by Sam “Captain” W. C
    Just starting out in electronics repair and teaching myself as I go.
    I have here a Corsair RM650 ATX PSU, which I'm treating as a learning project that if successful may be used in my PC.
    Fuse was blown, probable power surge from lightning, followed the circuit and found, a dead relay and all the diodes and resistors around the bridge rectifier shorted. Rectifier and MOSFETs seem fine on the LCR.
    Also found these tiny diodes on the other side, a few shorted, the rest seem fine. But they're not all marked as Zener on the pcb. So I'm unsure what these should be replaced with....

    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.

    MacBook A1706 Touch ID
    by PITERPENY
    They brought the MacBook after another service and the touch ID doesn’t work, and it’s not surprising because the cable is broken. How to get out of this situation so that the touch ID works? who did it? I’m still thinking about repairing the cable, but it’s not clear where the information is stored, on the cable or in the sensor itself?...
