    MP3389EF Ic needed

    Hi,

    I'm trying to locate an led controller ic for an Insignia NS-24E730A12
    The tv was hit by lightning and I repaired the power supply. All the features on the tv work now except for those related to the led backlight control.
    The power supply (6MS0082010) has a daughter board that includes a Monolithic Power Systems ic numbered MP3389 EF which is bad.
    I've looked on the internet for a source. Mouser is one company that lists the part but does not have stock and there is a 10 week lead time.
    If someone out there has one of these sets with a broken screen, the above ic or the daughter board I'd be interested in hearing from you.
    I've e-mailed the company (MPS) but got no response.

    Thanks,
    Mike

      Panasonic switching power supply daughter board has two 27uf @ 50 volt capacitors which I do not keep in stock
      by sam_sam_sam
      I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow

      This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board

      Replacing SOC SRK08 clean me needed?
      by DeXXter
      Hello, so I replaced a soc SRK08 (i3-1115G4) on a hp 14-dq because the 1.8v power supply was shorted and the pch was gone and I installed a SRK05 (i5-1135G7) that I had at hand. And I was wondering if a clean me region is needed after replacing the chip, I usually do this on laptops with separated pch, but with a soc (cpu and pch together) I have no idea. Normally I wouldn't ask this, but I have only the motherboard, no screen nor the adapter, and after I fix this I have to send it to another region so if someone knows about this, some help would be apreciated.

      Note: After doing all...

      Need help removing “Managed by: ABC Company” from BIOS on Surface Laptop 4 and 5
      by nerujan
      Hello everyone,

      I need step-by-step guidance for an issue I’m facing. I’m a technician, and I have several Microsoft Surface Laptop 4 and Surface Laptop 5 devices that were MDM-locked through Autopilot.

      There is no BIOS password, and I successfully removed the Autopilot lock using PowerShell. The laptops now work fine, but the BIOS still shows “Managed by: ABC Company” under the Management section.

      I would like to know how to remove this management information from the BIOS without changing the serial number. I’ve searched a lot but couldn’t find any...
