    Common mode choke failure in smps!

    If I remember correct someone posted here a case of a psu with input filtering coil burnt.

    In this review of club hardware, 2 identical Spire psus both fail in the same manner. The common mode choke responsible for filtering EMI fails.

    The reason could be bad insulation or ridiculously undersized copper size. I can't think any other possible explanation.

          Carrier HK50AA063 display controller common failure help
          by ctroxtell
          I've got a control display for a Carrier chiller that I'm trying to understand what the common failure with these boards are. This is the board in question https://www.supplyhouse.com/Carrier-...arquee-Display all of them seem to develop a failure with the up and down arrow buttons on the right side of the display, the esc and enter keys I've never seen fail. Once these boards are plugged in they run 24/7, you used to have to press extremely hard with the end of the blunt screwdriver and you could still get the arrows to work but now it has completely stopped working. The button...

          KingWin ABT-650MM 650 Watt ATX PSU [PCB: SW8835REV:A]
          by momaka
          For today's thread, I have a KingWin ABT-650MM ATX PSU. Official web page with the PSU specs is still up and can be found here:
          http://www.rmac.kingwin.com/products.../abt_650MM.asp

          I just can't help it when I see a broken / for parts PSU on eBay that's listed for cheap and looks at least somewhat interesting. Well, OK, I won't lie – on the outside, this PSU looks anything but interesting. It's a plain gray box with colorful “spaghetti cables”.




          What mostly drew me into buying it is its 2x PCI-E power connectors...

          Onkyo DX-V500 Laser Disc Player - weird SMPS fault
          by dkneyle
          This relic from a technology path that came to a dead end (but still has historical interest) was brought in with a dead SMPS, which is based around a MK1210 device. I got it going after a battle. It seems to have a strange design - if it's not getting feedback that the secondary is OK it cause the big FET to go into full conduction and overloads resulting in a blown fuse at best or something worse! I'm using a Dim Bulb Tester (70W/230V) which thankfully has saved the day a number of times whilst repairing.

          Now, it loads a CD OK. The motor voltage output (which is built onto the SMPS...

          KDM 480W PSU upgrade succes! (opinions?)
          by bauto601
          Back in 2020 i bought a (2nd hand) compact ATX psu to replace my current one. My PC case only fits very short ATX power supplies so i didn't really have the choice of buying a decent 80Plus unit. The current unit is a modded YoungYear unit that i made a thread about a while ago:
          A "nice" YoungYear unit? - Badcaps

          The "new" unit is a KDM-M6480 480W psu, the 480W number is a typical KDM bullshit claim of course, but the 24A rating on the 12V rail seemed reasonable and the "Active PFC" claim gave me a bit of hope that this was going to be decent-ish....

          Air Con PCB repair : some general question
          by dicky96
          Hi guys
          I've been getting more air con controller boards of various brands for repair - mainly the ones from the outdoor compressor unit and I realise I have a lot of gaps in my specific knowledge, while being pretty good at electronic repair in general.

          Does anyone know of any good resources for information on this sort of repair? I'm hoping here there will be some guys who are experienced in this. I'd specifically like more info on how the controller PCB works, because I expect they are all pretty much the same, and especially how it communicates with the indoor unit (protocols,...
