    Quecoo T12-958 soldering station - INVER error?
    by spleenharvester
    I bought a T12-958 recently with an M8 handle and until now it has worked very well. The tip wasn't earthed but that was easily resolved.

    Now, whenever it is switched on, it heats up to about 70*C then shows an [INVER] error on the screen and stops. In order to fix it I have to either unplug and re-plug the handle, or unplug and re-insert the tip from the handle. While doing that it changes to [ERROR], then it finishes heating up and works perfectly. Until it's turned off, after which it will show [INVER] again next time it is turned on.

    Any idea what the problem is?

    I need binary for Epson L3150 printer, I describe what happens to me here...
    by valente222
    hello everyone.
    I need binary for Epson L3150, this printer is something special today. It happens that when you connect USB to the PC, it does not recognize drivers nor does the software even find it to load the emergency firmware again. The device only turns on and the power button LED remains constantly on. The head normally comes to its ready position but does not react to buttons or scan. I point out that I have also tried installing a new head, scanner or new button panel... but it is still in a vegetative state. Has this ever happened to anyone?​...

    Identifying component Flyback? DC-DC?
    by unimatrix93
    Can I ask you guys help me identify this godforsaken component?

    I'm tearing my hair out finding this component.

    The board is from an egg incubator.
    i got it with a "popped cap" while there are many damaged components on it, which got succesfully identified with one exception:
    [ATTACH=JSON]{"data-align":"none","data-size":"medium","data-attachmentid":3267072}[/ATTACH]
    And here is the board where it came from (U1/1):

    Lg oled 55ec930v automatically turns off after 1-2 seconds

    Hi Community,

    I've got the above model that activates the relay (clicks) and powers on the LG logo power light on when turned on. It then almost immediately turns off. I not noticed any image on the screen or heard any sound during this brief period.

    Checks show:
    3.5v on SMPS on (in off state, no other voltages present incl pwr on)
    On pressing power button > the 3.5 pwn on voltage, 12v and 24v lines appear on the SMPS connnector between the main the SMPS but then all drop the zero in 1-2 seconds
    Disconnecting 24 to TCON connector and powering on shows...

    Battery not charging in ASUS G532LWS Motherboard -> BQ24780S
    by cope
    Hi everyone,

    I have been working on a no power issue with my personal ASUS gaming laptop. It went dead a few months ago.

    Some history:

    Since then, I've found a blown mosfet on the GPU line which I replaced. It started up without a battery, then when I added the battery back it wouldn't start up again.

    As a result, there were some blown components around the BQ chip. (The BQ chip itself - BQ24780S, the low side battery mosfet (shorted), and a resistor -> all replaced)

    Now, with a new battery the system will start up and run off...

    Samsung QE50Q60TAU - Horizontal screen lines
    by Runlinc
    Hi everyone, the tv was in a continuous reboot cycle. To get the best screen image i can I taped the VGH and VSS pins on the left side buffer board joining ribbon.

    I am left with a good image apart from the black horizontal lines that I cannot get rid of.

    I cannot find anything on the buffer boards that has shorted.

    Do you think there is anything i can do to eliminate the lines, or are they caused by an internal panel short and the image cannot be impoved.

    Many thanks for your assistance

    Lenovo Ideapad 320-15ikb: Comes on and goes off
    by Nagyesz
    Hey guys, I have a Lenovo Ideapad 320-15ikb NM-B241 rev:1.0.
    After turning it on, it runs for a few seconds then shuts off completely. No screen, no fan. After shutdown, a red light comes on and off fast. I've been trying to troubleshoot this for days now. It's never been opened up; the Lenovo sticker is still intact.

    (!)I tried with a different BIOS battery, without any ribbon cables, on battery power, without the keyboard, and it's always the same.

    Any insights on what might be causing this?...

    Samsung LED UHD TV - Bad Main Board or Bad T-Con Board? Pictures inside
    by E--Man
    Hi All,

    Thanks for reading. Based on the interesting fact that the vertical lines issue don't seem to effect the menus whatsoever but rather everything around the menu regardless of video is shown, I'm trying to set mine whether the issue is the main board or the t-con board.

    Again what's baffling is that the menu is not effected whatsoever. However, any other video displayed regardless of inputs or when no inputs exist exhibits the vertical lines and seem to effect black areas only.

    The lines are green in color when the tv is in "Game Mode" and...
