    Liteon PA-12617 dead (Lenovo ideacentre3)

    Hi Guys,
    Trying to save this PSU from going to the bin.
    PSU was found dead:
    1.. Main fuse blown
    2. Main switching transistor shortes
    3. rectifier bridge shorted
    4. low ohm resistor blown

    replaced all of the above (resistor was replaced with a. Thin wire since i don't know what was the original value)

    Have 330v on main cap. But standby is still not right.

    maybe the driver chip died?

      Could very well be. After all the gate drive of the MOSFET got full power once it shorted out all 3 pins.

          Help Needed: Samsung UE55MU8000 Dead - Possible Main Board Issue
          by Asraf Atb
          Hi everyone,

          Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.

          Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.

          I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue....

          Lenovo ideapad 330ICH - Dead, no volts on coils
          by Nagyesz
          Hi everyone, I replaced this motherboard because it was important to get it working, but it's been with me for a very long time. Now I finally have time to figure out what the problem is,
          I've never encountered something like this before;

          Lenovo Ideapad 15IIL05, turns on and off with charger BUT works by injecting 20v after main mosfets
          by NanoTesting
          I got a 15-IIL05 that failed to turn on BUT IT DID TRY TO TURN ON and then turned off after 30+- seconds, i disassembled it and found a screw loose inside the case.
          With charger it turns on, fan spins but gives no image.
          Tested main mosfets no short, tested 3.3v,5v,DRAM, CPU etc and they were present.
          Reflashed BIOS, same problem.
          Replaced both main mosfets.
          Checked main mosfets again and i noticed that they closed once the laptop shut down, so i decided to bypass them and used a bench PSU to check how much power the laptop was drawing while trying to turn on, 20v@3A,...

          Lenovo Ideapad S130 is the CPU dead?
          by madan1
          Good day.
          I'm trying to figure out what's wrong with a Lenovo Ideapad S130 motherboard. When I connect it to the bench PSU and limit the supply to ~2.2A (about the limit of the lenovo stock PSU), the board absorbs all the amperage and the voltage on the PSU drops down to about 4-5V.
          The components on the board that get hot are the two mosfets ( 1 and 2 on the photo ) and the CPU. The resistance to ground measured on the power rail coils can be seen on the image (~17 and ~50 ohms). On the top of the CPU there are few caps which measure dead short. I checked all caps on the top side...

          Lenovo NM-A921 (Yoga 900-13ISK2) dead
          by reformatt
          This machine has been in a few times with an intermittent fault of not charging. Motherboard is NM-A921 (https://www.badcaps.net/filedata/fetch?id=2051581)

          So back again now, not working at all. Previously the adaptor had been replaced along with the DC charge port. This is one of these trapezoid shaped orange USB ports that Lenovo were using prior to going USB-C. It has 4 pins, but the DC connector jack on the PCB has 5 pins.

          Fault presentation was the adaptor is only producing 5.2V, not 20V and this isn't reaching the input of the NVDC charger (PQ5/PQ6). There are 5...
