    So did you replace the 4-diode treatment with a bridge rectifier?

    The 4-diode treatment is typical with cheap PC PSUs...

      Re: KRK Rokit 5 Gen 1 pops fuses as soon as it's powered on

      Hey there,

      I'm trying to fix my Gen 2 that has the same fuse blowing problem.

      First I've tested that the power supply and transformer (the first part that plugs into the circuit board) are working by testing that on another monitor.

      Second I've tested the 4 bridged diodes and the upright rectifiers in circuit and they are giving seemingly OK readings of ~600 and nothing the other way.

      Thirdly none of the capacitors seem to be bulging or fried or otherwise abnormal. Is there a way I can test them in circuit?

      What should I test next? I also have a matching monitor with a broken and bypassed amplifier that I was hoping to use to somehow get 1 working monitor out of the 2 broken ones!

      Thanks!

        I took a second look last night and retested all the diodes. One of the upright rectifiers was in fact broken so I just replaced it with the one in my other monitor and voila it's working great now!

            HH Scott Model A510 Stereo Integrated Amplifier/ Graphic EQ - Blowing fuses in the LEFT speaker channel only. Any Help???
            by Sik_6ty_Sixx
            So like the title says, I have an old Stereo Receiver/Amplifier that I picked up from the goodwill, it's a HH Scott Model A510. When I first got it home it had zero output. Opened it up, notice the fuses are missing. Pop in 2 new fuses (AGC4A 250V) and try again, within 5 seconds the L channel fuse POP! I don't see any visible indications of damage or arc burns on the PCB, no popped resistors or diodes, no burnt traces or blown out caps. So I decide to just try another new fuse, POP. Swapped around my R and L speaker wires, and checked the integrity of all wires and connections. Everything looks...

            How an incandescent light and a ESR meter ** friend**have a machine blowing fuses
            by sam_sam_sam
            About a month ago we had a transformer jumper wire that burned in two different places between two transformers caused over $200 thousand dollars worth of damage to VFD drives at least 10 of them and a memory card and quite a few power supply as well

            Now we have most of the equipment that got damaged back up and running except a feeder that has issues and we are waiting for some parts for

            Now we also have another piece of equipment that was blowing fuses on the 110 volt controller switch circuit with the “E” stops and one switching power (24 volt) supply and a transformer...

            Power supply for main amp blows fuses after replacing filter caps.
            by acedogblast
            Hello I have a Marantz sr5012 that I have been repairing. After I have replaced the 2 main filter caps the 2 fuses for the power amplifier blows. The original capacitors are ELNA LAO 10,000uF 71V and the replacements are Nichicon LKS 10,000uF 80V.
            I assume a short circuit connection has occurred so I set my multimeter to measure ohms across the 2 fuse connections and both read 55 Kilo-ohms so I assume that is ok.

            I am certain that I do not have any bridges on my soldering and after probing around I do find a temporary 0 ohm reading when probing across the positive and negative...

            Samsung UN39EH5003FXZA won't stay powered off
            by Hannibal_Hector
            Hello,

            Purchased a broken Samsung UN39EH5003FXZA (Version CD01) to have fun fixing. When I first acquired it, I did not connect any video signals and only plugged it into the wall. The unit booted and showed the “no signal” window and I could navigate all menus and change sources. I unplugged it, connected my over-the-air antenna to the coax, powered it on, got the unit to scan the HDTV channels, and I think then the TV self-shutdown with the melody. When I powered back up (melody), it would show the channel selected on the OSD and after a couple of seconds, it self-shutdown...
