    Re: sharp lc32d42u power supply - DPS-178APA

    Yes it can be tested without a load. It is only to confirm that the power supply is turning on the panel power 5 volts. The PS-ON resistor is to turn on the main power supply (which is confirmed to work) the PNL_POW resistor is only to turn on the panel 5v
    normally the main board provides the 3.3 volts to turn on the power supply and the panel power, the resistors are to simulate the main board. The main board should not be connected when forcing on the power supply.

        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...

        Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
        by Tynan Dill
        I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

        Upon bringing it home and plugging it up, it showed a standby light.

        I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

        The screen seems to blackout and stay black, but with a flashlight I can see the display.

        With my Playstation 4 connected via HDMI, and running a game I can hear sound.

        Assuming...

        Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
        by sam_sam_sam
        I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

        One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

        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...

        Modification to a ZD-987 desoldering/soldering station using a external switching power supply
        by sam_sam_sam
        I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails

        I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time...
