    DVR camera recorder switching power supply capacitor failure really

    These cheap non brand capacitors at it again

    Last night we had a power outage [ long drawn out trying three to come back up before going out completely ] and when I went to turn the DVR camera recorder back today no go 3 bad capacitors ( one capacitor no ESR reading on DVR board the other 3 capacitor on the power supply board over 40 ohm this is not a misprint ) on the external switching power supply and one capacitor on the DVR camera recorder board where the power supply that goes to the hard drive disk is

    Well at least I have the cameras back on line I to try the hard drive tomorrow and see if it got damaged as well

    One note the cameras are on a medical grade switching power supply by themselves because when I first put in this system I continuously had switching power supply failure on the cameras and had to replace several cameras and switching power supply of because of switching power supply failure

    All I can say good about this DVR camera recorder and switching power supply is that this has lasted about 6 years so I guess I really should not complain to much about it

    I will post some pictures of the switching power supply before I put heat shrink tubing on it to keep it together and after I try the hard drive to see if it still work

    6 years = 52,594.92 Hours, I would say that cap had a full life

      6 years POH or 6 years sitting in the closet?

        Yeah it even keeps trying to restart which is really weird even with the capacitors being at over 40 ohm ESR reading because the power supply light pulsing very quickly on and off on the DVR camera recorder

          Well is has been running scene last night and so far so good I am supposedly going on vacation next week but not this Monday but next Monday and then I will test the hard drive and if still good will put it all back together and call it repaired

            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...

            Mitsubishi CNC switching power supply board dead / relay board bad diode failure
            by sam_sam_sam
            I was working on this CNC machine today found no keyboard functioning no control relay powering on
            The screen powered on and was giving an operation error but the manual was not very clear about what the error exactly was but with a little bit of troubleshooting and finding out that the control relays not powering on and no keyboard functions we narrowed down to this one switching power supply which of course does not have any indicator LED light they are on the keyboard interface/relay controller board

            Found shorted diodes on main controller relays there are 3 of them that...

            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...

            DVR recorder Switching power supply Failure
            by sam_sam_sam
            When I originally started with my DVR recorder it had 4 individual switching switching power supply’s that were sh*t so I bought a 7 amp 12 volt switching power supply and modified the output plug and put a four output power supply cable to match the input power supply cable inputs

            Which worked for over 14 years until a few days ago when the cameras went dark no picture anymore well it turns out now the switching power supply has stopped working altogether now so I have to troubleshoot what has happened to this power supply more later on today what I found

            This...

            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...
