    Possible Magnavox 32md357b/37e purchase

    The owner says the picture looks perfect when it turns on,
    but that it only stays on for 15 seconds, and then shuts
    off by itself.

    Sounds like a power supply bad caps problem to me.

    This model has a built-in DVD player. 32" screen.

    How much would you all offer for this one?

          So by this you mean the inverter itself shuts down,
          NOT the +24V coming from the power supply, right?

          What would cause the inverter to shut down in 15
          seconds like this? I would guess an overheating
          issue would take a bit longer.

          Over-current protection scheme?

          Would it be an easy and cheap fix?

              No idea, and no idea. Sorry. Never encountered it myself.

                  MacBook Pro M1 Pro Logic Board 820-02100 Mosfet where to purchase?
                  by prodigy83
                  My reference only: TT10141.

                  Problem: I need to purchase a mosfet chip from board 820-02100 M1 Pro, that is supposed to be Q5820 but according to Digikey, the schematic diagram I sent them, neither are relevant to the actual mosfet specification I sent them. I just basically need to find this mosfet to purchase, I cannot find it anywhere and am hoping someone could point me in the right direction without have to purchase this entire allusive board. Already checked with Digikey, Mouser, Aliexpress, eBay. Any suggestions?

                  Mosfet specs are as follows:

                  Chip markings:...

                  Asrock z97x starts then shuts off after 4 seconds, sometimes more, no post
                  by chaos-theory
                  I have a really weird problem, this motherboard was working normally, someday it just started and all fans were running but didn't want to post, tried resetting bios, checking CPU and it was getting warm tried external gpu, flashed bios with programmer, but same problem.
                  Next day after several attempts the board goes into protection mode, no more staying on, I turn on the PSU fans starts directly turning, it used to not start until I press the pwr button, now it starts directly and fans spins, and shuts off after 3 seconds sometimes less, then won't start again unless I unplug the PSU and...

                  A1706 820-00239 - Works, but sometimes shuts off when the charger is disconnected
                  by baglaivlad
                  Hello everybody!

                  Have in work A1706 820-00239 model. Originally no power, shorted PPBUS_G3H because of corroded C6403, C6404. Some water damage around this components, but nothing major.

                  After replacing this capacitors the laptop came back to work, I reinstalled MacOS and had no issues until I started to test Type-C ports. Sometimes the laptop shuts off immediately when some action with Type-C ports performed (charger disconnected or USB device inserted/disconnected). I checked Type-C port flexes, they are okay, but I cleaned them anyway. I can't see any signs of liquid...
