    Re: Bestec....the next generation

    May also be bad wire insulation.

    Anyway, is there any way how to find what material is a coil made from? I got lots of coils from different places (input filtering, common secondary coils, PFC coils). If some coil burns somewhere (and that happens), I may be able to just take different core and wind my own replacement but as the material properties differ, I am not sure if I can just pick up any toroid of right size no matter what it is made from…

        Here is another TFX0250 Bestec with a burnt group regulation coil, also pc board burn damage. Perhaps this is a trend.

            Viper22A 5VSB circuit
            by прямо
            So I have a cheap non working ATX PSU that I was learning to repair a decade ago. At the time, it blew the main fuse, bridger rectifier, NTC, and primary 9A 900V MOSFET. Replaced all except the MOSFET. 5VSB came back online. Then I poked around in it so much, measuring components one by one to a point I accidentally made the 5VSB circuit primary side went bang. Blown the AP8022 (Viper22A) PWM chip, along with a low resistance resistor and the PC817 opto isolator. I replaced them all.

            In the process of poking around, I also lost a zener diode that stabilize the voltage coming from...

            FSP300-60GTF - no 5VSB, PS_ON; 5VSB carnage
            by kotel studios
            Hi,

            Finally replaced all of the shorted 4148's and resistors and an blown tl431 on my FSP300-60GTF after 5VSB going crazy and destroying it self. Those components also made the secondary transistors appear shorted (while in reality they weren't).
            Powered it on through my dim bulb tester and they (bulbs) only flash once meaning primary caps are getting charged, but that's it. No 5VSB, PS_ON voltages.
            I am sure I have replaced the components correctly and that there weren't any shorted/blown traces left.

            Any ideas where to go next?

            external hd Seagate, broken down the +12 volt and USB 3.0 SATA board
            by gabri2211
            Hi to all 😎
            I'm looking for any useful information to repair this interface (I have attached the image).
            On this board I read E3215-1215A_4D.
            This is the small plate inside the HD enclosure that allows to connect a 12 volt power supply, interface the disk with a USB 3.0 socket and is connected to the HD with the SATA connector.

            If any of you have found a burnt or short-circuited component in a circuit like mine​, if you have useful diagrams for the repair, or even better a description for the tests at the test points, I would be very grateful.
            in particular...

            CM V700 no +5vsb, ICE2QR4765 low VCC in... Need guidance please...
            by mrcliem
            Hello...

            I got my self a dead CM V700 PSU, with nothing on +5vsb

            I have tried to fix it for the past 2 week, and I'm stuck... so i guess i post it here to get some pointer before i scrap it..

            As you can see in photo, the psu still pretty clean, no visible damage or bulging cap.. when i got it, it still has CM seal on it

            The +5vsb system use ICE2QR4765, I have trace and measure the voltage on ICE2QR4765 and the only voltage reading i got is in VCC 4.8v, Drain 310v and FB 3v.

            I have read the datasheet and and still can not...

            Using a 5 volt @ 12 amp switching power supply and two USB doctor volt / amp meter to three IPads on one power supply
            by sam_sam_sam
            I have been wanting to do this project for some time using a Mean-well switching power supply that I bought at least ten of them that were originally in a device that was abandoned for some reason they were listed new but removed from equipment that was never used

            I do not understand Mean-well the capacitor next to the voltage reference ic chip was a brand that is known for failure over time the other capacitors are brand name needless to say it got replaced before I even powered it on for the first time

            I used a four USB outlet and electrical plate that is made for...
