    Fixed a couple of these, couldnt find a thread on them. Both failed the same way.

    Powersupply: EAX55176301/12

    Symptom: dead no 5v, both fuses ok.

    Check ZD501 (3.6 Zener) R501 (2.2ohm 0.5w resistor) IC500 (ICE3B0365J)

    usually zener, IC are shorted and resistor OL or very high.

    replace zener, resistor and IC500 (ICE3B0365J)



    Schematic attached.
    Here, found the same problem. However Zener looked ok ( I changed it anyway ).

    Replaced all components and it is running fine.

        NTE Electronics “NTE5251K” Zener Diode 9.1V @ 50W Do-5.5% Want to build a 9.1 output from a 9.6 lipo4 battery pack
        by sam_sam_sam
        I have bought this Zener Diode for this project what size and wattage resistor value do I need to use to get near 50 watt output
        I bought this from an eBay seller but unfortunately they only had one

        I bought three from Vetco Electronics these are Sylvania ECG5185A 9.1@10w A to Stud what size and watt resistor do I need to use to get near 10 watt output
        I bought three of from them to also make battery packs with this output power limit in mind

        I want to use this battery pack and turn it into a 9.1 output battery pack output to eliminate using 9 volt battery...

        What Zener Diodes on a Linear Power Supply
        by caspian
        Dear members,

        I have a linear variable power supply with unknown brand name that I used for voltage injection.
        Then it failed. I discovered that its transistors (Q1 and Q2) are shorted.
        In addition, I discovered that its zener diodes are defective.
        I can replace the burned transistors.
        But I do not know the model of the zener diodes. the model number is not marked on the zener diodes.
        Therefore, I cannot replace the zener diodes.
        I do not want to test the zener diodes in a test circuit to discover their model or value.
        no schematics are available...

        On M-Audio AV40 active studio speaker's two zener diodes get really hot.
        by Dvsr
        Hi. I need help from wiser guys. I am amateur in electronics and can't figure this out by myself.
        I bought faulty speakers, M-Audio AV40's. Other speaker has all the electronics in it and the other speaker is just passive one powered by the other speaker's amp. Original problem with the speakers was loud buzzing. I figured out that there is something wrong with the capacitors. I went ahead and replaced every electrolytic capacitor on the PCB. The caps are good quality and have the same values as the original ones.
        After replacing the caps I started testing out the speaker. It seemed...

        Sharp Aquos Quattron LC-52LE835X Totally Dead, no output voltages
        by Joekhoe
        Hello all, I'm Joekhoe, a newbie here and ask your masters permissions and solutions for the problem i'm facing at the present.

        I am in the middle of working on a SHARP Smart TV model LC-52LE835X from my customer, which totally dead and there's no output voltages at all at the output pins even though i have replace some of the components the output voltages remain the same with 0 volt.

        The replacement as follows:
        1. IC7905 : TNY264PN (first found exploded)
        2. Q7915 : BT169D (exploded too)
        3. IC7901 : 1608B (controller ic)
        4. IC7601 :...

        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...
