    Need power supply repair

    I have an apparently very custom power supply from a Vidar P-87 wide format scanner. I contacted tech support because one day the thing was dead... no lights, no motors, nothing. Tech support straight off said it was the power supply, and to contact their supplier. Supplier wouldn't let me order from them, so I had to contact a reseller. This person said he didn't have the part number on file, so he would need to contact the supplier. I got a call back a few hours later and I was told the part would need to be custom built because there aren't any left and its old (4 years is old huh?) for a really rediculous amount of money (the scanner new was $10k though). So I balked at the price because I am not 100% positive it is even a bad powersupply. I did test the ps with a volt meter and I wasn't getting any dc voltage reading from any of the various outputs. Fuses all passed continuity tests. All the caps appear to be in good condition.

    Thats about as far as my knowlegde of power supply components go. I've recapped a few mobos, but thats it. There are many other parts, I dont know how they work, nor do I know what they are called. I wish I had the time to learn about it and fix it myself, but I have many other work obligations. The size of the ps unit is comparable to a ATX ps, however, there are some leds that seem to indicate it supplies 24v in addition to 5 and 12v. I wish I had some photos to post, however I did not have a camera and the scanner is located about 250 miles from my office in a remote office. I could however have some photos taken in approximately one week to post if that would help.

    That said, I have a feeling there are at least a few people here who might be qualified and willing to try fixing this power supply. Please let me know. I'll pay reasonable parts and labor.

    Re: Need power supply repair

    Pictures would be of great help, because it is difficult to say if someone will be able to fix it or not when you have not got any idea how the thing looks...

    However unless it actually needs some very special voltage supply there is a good chance that you could hook up some other powersupply too it, of course they are not exactly cheap either

    Yes, you are right there are people here that could fix it for you, but first you need to tell us atleast on which continent you live...

    Good luck

      send a pm to kc8adu he is most qualified to fix your psu. He is often repairing very expensive industrial hardware.

          I just wanted to say thanks to kc8adu who successfully fixed my power supply. It apparently had a few bad caps and a bunch of bad solder joints. I would recommend him to anyone looking to fix a power supply of this type.

            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.

            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...

            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...

            Definitive technology SC 2000 subwoofer amp's power supply clicking and popping
            by JimBanville
            The sub developed a constant popping every couple seconds from woofer and power LED flickering with nothing but wall AC connected. Connecting an audio cable didn't change anything. It doesn't play but a second or two of audio in between the pops.
            Opened it up and discovered the power supply is making a faint clicking or ticking sound.
            I measured the amp's output to the woofer and it pulses up to 50mv DC to be driver. The pulses coincide with the power supply ticking/clicking.
            I measured the power supply output going to the amp board and it too has this pulsing. Voltage cycles...

            Russound CA4 Power Supply Repair
            by CMCM
            Hello Everybody,

            Trying to repair a power supply from a Russound CA4 Multizone Controller (picture attached)

            Russound no longer supports it but were kind enough to provide a schematic of the power supply (pdf attached).

            The outputs marked 12v and 20v are all measuring only 1v.

            The board is clicking, which I think means it is in something called hiccup mode when the flyback transformers switches because of an internal problem or something else on the board Overloading it.

            The capacitors physically look clean (no bludgesor leaks) and...
