    LHP 432171-001/Lite-on PS-6421-1C-ROHS strange state

    I got this PSU with +5VSB caps replaced as they've been bloated but it is still not working OK. When I plugged it in, it turned on automatically with fans running very slowly. I has +5 V SB voltage OK, as for the rest, those are some fractions of V.

    There is very low resistance from +5 V SB to ground, only some 17 ohms but that is probably not the problem, there are "1500" SMD resistor, if that's 150 ohm than with 9 of them it is aprox. 17 ohms. Possibly secondary monitor (PS224) problem or something similar?

      Epson EB-U42 projector / Caps with 0.7 ohms ?!
      by narf
      hi all,

      first of all: i'm a (motivated) newbie, so please forgive me any stupid question i may or may not ask

      i'm currently repairing a projector: Epson EB-U42 that doesn't start (no lights, nothing).

      what i've found so far:
      - the PSU does its job and supplies 12V to the mainboard via the connector.
      - shortly thereafter, there is a mosfet (TS420-600B) where i can test 12V on the one side (in the data sheet this side is called Anode), Gate 0V, Kathode shorted to ground
      - not far away, there's the first cap with a resistance of 0.7 ohms....

      Need help to identify and to locate a 0.33 ohms fusible resistor for power supply
      by gica69
      I have a quad charger that is split into 4 separate sections and one section doesn’t charge anymore. I have located what I think is a thermistor and on the shrink tube it says 125 degrees C. I cut the shrink tube and it's a 33 ohms resistor. It measures a little less than 1/2 inch in length. I am including pictures of it. Please help me identify it. So, it should test at 0.4ohms and probably go up in resistance with the rise in temp. On the board it clearly says R for resistor. But it has to be a special one.
      Resistor shows orange range silver gold and green lines.
      Thanks in adv...

      Dell XPS One 2720 AIO Liteon PS-3261-9DA not starting up immediately
      by cheeky2
      I suspect the issue is with the power supply Liteon PS-3261-9DA as apparently they are notorious for issues with them. Has anyone else had similar issues where the PC tries to boot up a few times before finally booting up. Now I have opened up the PSU which shows no signs of any capacitors failing. I did remove one capacitor that looked to have an issue however with my peak meter it showed it was within the limits with good very low esr values which was somewhat disappointing!
      I am going to put a Meter leads across the outputs to see how stable they are when it occurs to see what they are...

      DELL XPS 15 9560 - No VCore, Power Off after few seconds
      by Sephir0th
      Hello Community,

      i'm troubleshooting this one since days and actually i'm really lost because i believe i'm Missing the required experience for an issue Like this...

      It is a Dell XPS 15 9560, i7-7700HQ, GTX1050 Board Number LA-E331P Rev 1.0, Most similar to LA-C361P so i use this Schematics.

      Issue: Starts and shuts Off after a few Seconds. Basic Troubleshooting (Adapter,RAM,BIOS/EC Flash from alisaler) of course already done, which didn't Changed anything.

      I have another working Board with i5-7300HQ and GTX1050, with It's Help i can compare...

      Hi everyone, I replaced this motherboard because it was important to get it working, but it's been with me for a very long time. Now I finally have time to figure out what the problem is,
      I've never encountered something like this before;

      No charging light, full dead
