    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.

    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...

    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....

    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.

    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

    Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
    by Mgiffune
    [FONT=Arial]I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. [B]If I power cycle the TV, the display reappears, for another 10-15 minutes[/B], then fades black again. Repeatable ever time.

    I ordered a supposedly ‘new' Tcon

    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?...
