    Component Identification

    Hello guys,
    Recently a friend of mine had an issue with his air conditioning unit and he brought me this board to see if I can make it work again. The board had a nasty encounter with water while it was powered up and as you can imagine, some things shorted out.
    After the initial checkup, besides other things, I have found what it looks like an LC circuit but it seems like the inductor is encased in glass. I'm not sure if that is an inductor or not, I've tested it with a multimeter and doesn't show any readings.
    So, my question is: What is that thing, is it normal not to show any readings, and if it's bad what replacement should I get ?

    Thanks alot.

      Re: Component Identification

      That is Surge Arrestor/suppressor (SA, Gas discharge type), it should show open circuit. It is not need for the circuit to function.
      BTW, did you remove that Common mode choke?
      What Voltage testing have you done so far?

          Yeah I temporary removed it and that relay on the left side to make a clearing so I can work in peace.
          Haven't managed to do any voltage readings yet, the board was too damaged.
          I have to replace a coupe of SMD optocouplers PC1 and PC2 in the first picture next to the 3 diodes as they had 2 legs coroded clean off, also a couple of 470k and 68k burned out smd resistors, and redo a big circuit trace and check on many others especially under large components.

                  Help please with identification of few components for troubleshooting (Solar Water Fountain circuit)
                  by Techie_hobby1
                  Need some help please with a few components on this small board so that I can troubleshoot the circuit.

                  The PCB is a Single sided board fairly simple circuitry has a +ve and -ve Solar cell power input, a 7.4v 1500mAh (dual 18630 cell) power in which the Solar panel charges the cells, and lastly the Output goes to a DC connector...
                  J1 is actually 1P1T Switch (in ON position completes Battery cell circuit
                  J2 - to DC Output
                  J3 is Battery cell connector

                  however I am struggling to identify if:
                  Y1 (SOT-23) are NPN Transistors, MOSFET's or 11v Zener's....

                  by grimacelord
                  Hello. I am working on a circuit board that is part of a motorized HDTV lift. The circuit board belongs to the controller component that tells the motor to either raise or lower the HDTV height.

                  The controller started sparking when the 29V power supply was attached and the green light on the power supply would go out as soon as it was plugged into the controller board. This indicated a shorted component and I was able to identify which component it is that is causing the short. When I remove this component, the short is cleared.

                  The problem is finding a replacement component....

                  Corsair CX750M [Model 75-002019] - burned output toroid inductor
                  by momaka
                  Looks like I may need a little help from the PSU experts (or anyone really! ) I have a Corsair CX750M (Model 75-002019) that I picked up for free about 4 years ago. This is the PSU:



                  So here’s what’s strange about this one: it appears to work normally (normal output voltages) and any PC is stable with it. However, after a while (typically 10-20 minutes, but time can vary depending on the load), there is a sweetish smell of burned magnet wire insulation emanating from the PSU. Upon opening the PSU after this happened (many times), I was able to confirm...

                  Ok I screwed up big time and hoping I can fix. I will break down what happened and the images.
                  • Have Dell PowerEdge R730
                  • Bought Tesla P40
                  • Researched power cables and order correct one, pic had two black connectors in photos
                  • Power cable arrived, same connectors (EPS-12v) on both ends
                    Both sides are the same plug but different colors. The listing stated that colors would be random. OK I plug it in, red side to riser board, black side to GPU.
                  • Power on.
                  • System immediately turns off.
                  • I only had 1 PSU plugged in and it was blinking orange, I thought I drew too much so I plugged in

                  Zombie Samsung UN55NU6900F dead / no standby voltage - randomly came to life after hours of troubleshooting then died
                  by tvguy12012012120
                  This is my first attempt at troubleshooting a board like this, I know I could just buy a new board but I'm curious to figure out how this works. I've been testing different components in the evenings this week and I think the problem is with the IC failing to start up for some reason. When the board is plugged in there is no standby voltage.

                  Then today it randomly sprung to life like a zombie but shortly died thereafter. I have no idea why it would have done that and its the first time I've seen it running. I discharged capacitors on the board last night, then it was sitting today....
