    ux32vd power failure ?

    The system goes on and after few second goes off, no short on coil, battery charge, 5v and 3v ok.
    I'm try to understand pwrgd signal to identify if there is a failure on pch.
    in the first pics the value on ux32vd board regard pwrgd signal
    in second pics a similar circuit that I have take from an asus k72 schematic to understand how this circuit work and I appreciate if someone can explain how it works
    what is the function of PM_RSMRST#PCH ?
    thanks

      PM_RSMRST#PCH is a signal from SIO to wake up PCH the value of signal is low voltage=0 if the value is high PCH will never reset or wake up..
      i assuming your prolem is in PCH,mybe you should try to reball PCH chip

          MacBook Pro late 2016 (820-00239) with multiple failure modes.
          by npielawski
          I will just preface all this by saying that I have a fairly technical background but have never attempted SMD electronics diagnostics and repair before, I really like the idea and want to learn.

          I have a MacBook Pro late 2016 that died maybe four years ago. Over the course of 30 seconds, it got slower and stuttered, until it froze for a second and died. No click from the trackpad anymore, nothing. I started getting interested in electronics repair and decided to give it a shot, so I opened it, removed the battery (one cell was puffy), took out the motherboard and experimented with...

          Dell 9310 Memory or RAM (Random-Access Memory) failure (2,4)
          by puccovelli
          Hi all, I hope this is the right place to post.

          I'm having a problem with a Dell 9310 which is posting 2 orange, 4 white lights on startup (hangs on Dell BIOS logo). The service manual says its a RAM failure.

          I've taken the motherboard out and noticed that one of what looks like an SMA 0805 resistor has blown (see photo). The board is an LA-J144P Rev 2.0(A01).

          1] Could someone confirm what the component that has blow actually is (and where I could get another from).
          2] Whether this component is likely to cause the RAM failure issue, and if replacing...

          TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
          by howardc64
          All left and right refers to looking from rear of TV (or looking from front with TV upside down)
          • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
          • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

          Carrier HK50AA063 display controller common failure help
          by ctroxtell
          I've got a control display for a Carrier chiller that I'm trying to understand what the common failure with these boards are. This is the board in question https://www.supplyhouse.com/Carrier-...arquee-Display all of them seem to develop a failure with the up and down arrow buttons on the right side of the display, the esc and enter keys I've never seen fail. Once these boards are plugged in they run 24/7, you used to have to press extremely hard with the end of the blunt screwdriver and you could still get the arrows to work but now it has completely stopped working. The button...
