    When you open it up, do you see any bad soldering?

      Re: Supermicro PWS-0060 *failure*, please advise

      i have seen a few liteon units with very poor soldering.
      fixed a neighbors liteon and when i pulled the pcb i commented it looked like a 2 year old with a cold iron and plumbing solder had built it.
      he commented that it looked like a mud dauber had been working on it.
      had one in a hp that had missing +3.3
      bad solder joints and crap caps.
      stay tuned for a ablecom dissapointment i got in last week.looks like a deer board inside!

        Wow man...doesn't look like the insides of my unit?

        The winding on the toroidal inductor, in the last picture is just garbage. Who-ever winded that coil should be shot.

          If the +3.3V O/P is mag-amp regulated, it sounds like the transistor driving the mag-amp inductor is either shorted or turned full on by whatever is driving it.

                Both the 3.3v and 5v have sense wires running back from the EPS connector to the PCB - can we assume that both be mag-amp regulated, or is something else at play here?

                  T, I don't have specific knowledge of this P/S, but unless it's a fairly high-end supply, I'm assuming it has a single main regulator, usually sensing the +5V and +12V. The other O/Ps are post-regulated - the -5V (if it has it) and -12V by 3-T regulators and the +3.3V by a mag-amp regulator.

                  The winding on the toroidal inductor, in the last picture is just garbage. Who-ever winded that coil should be shot.
                  Winding toroidal inductor with multiple windings with different numbers of turns and different wire gauges is seldom neat; making 10s of thousands of inductors a month is no mean task, either.

                    Thanks Pete for your advice... I'll be taking a look at it more closely now - componentwise it really seems *very* solid, I'm expecting a poor solder joint somewhere or other soldering-related issue as KC8 warned.

                    The inductors on my unit aren't badly wound at all, in fact. It's probably luck of the draw, as you said.

                        No comment on the inductor windings since I've seen a lot worse on a lot more expensive units.

                        As long as there's no "slack"....

                          Guys, this is my first server unit. Any ideas on why there is no power switch? I'm still a bit bummed by this.

                            Hehe... because servers shouldn't be turned off?

                            It can be annoying, yes. I had a separate switch on my surge suppressor for the socket to which I connected it so it wasn't really a problem. Perhaps you could do the same?

                            A question: does your 0056 model also have the fan running (at low speed) all the time, even when it's only providing 5Vsb?

                              I can answer that: Yes. The fan runs all of the time. Fire up the PC and it spins full RPM for about two seconds and then comes down to a bout 75% RPM.

                                Roger that. Exactly as Jonny said. It is whisper quiet, when compared to my x1800xl's scramjet HSF. That thing (x1800xl) is so loud at start up that I could hear it outside my lab.

                                Jonny, do you think I would trip something up if I unhook the fans and rewire it so that both fans are being used? This redunantant fan stuff is not my style. If there is a fan I see, it should be spinning. I hate lazy ass fans.

                                  I actually took one of eVGA 7800GTX's out of my machine simply because of noise. I'm eventually going to water cool the other.

                                      About the revision question:

                                      I see where yours has "REV 3.0". My unit has nothing there, ie. just white space on the label.

                                        Fake! Fake Fake!!!



                                        Another very very strange thing I noticed. The 12V line dropped to almost 0V for a fraction of a second, when I rebooted the now OC'ed Prescott !!

                                        Config:
                                        1 stick of 1Gb DDR2

                                        WTF is going on here?

                                          Surely it would have gone out had that been the case? Are you sure your multimeter/oscilloscope connection didn't come loose for a moment?

                                            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...

                                            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

                                            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...
