    just a little ask.

    i got samsung mobo with no power.

    i found faulty caps and mosfets

    caps (N8 dn) replaced with (J8 ew)
    mosfets (AO6912A) replaced with AO691

    after that a got lit on mobo indicator. i guess that got it working

    when i turn it on. it burns the caps and mosfets again.

    i just wanna ask if i got the right parts replaced.

          marking H or A at the end usually means same characteristic but higher current

              Check the feedback resistors from the mosfets to the ic controller

                  HannStar Hanns-G HC194d LCD monitor repair
                  by momaka
                  Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

                  Asus P4C800-E VRM issues
                  by c_corr
                  This board had the initial fault in VRM with high side Mosfet from PWM1 (phase 1) getting very hot. It also had the VRM caps quicly heating up in 10-15 seconds after power on.

                  This board uses mext ICs and Mosfets in VRM:
                  - ADP3180 PWM controller - in 3 phase mode
                  - ADP3418 as Modfet drivers
                  - High side Mosfets STD38NH02L (from ST)
                  - Low side Mosfets STD90NH02L

                  Some of the symptoms were very similar with the "Dead Asus P5P800-VM" in this forum.
                  I had the sawtooth voltage on Vcore too this was probably the cause of the Vcore caps...

                  Seasonic B12 BC-550 – barely 2 years old and with BAD CAPS already!
                  by momaka
                  I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.

                  For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

                  https://www.badcaps.net/filedata/fetch?id=3591772

                  It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

                  LG 42LB5D, 42LB5DF-UL, 2008-01, Power On Issue, Replaced PS Caps
                  by bcstedt
                  LG 42LB5D (42LB5DF-UL) from 2008-01, unit is in good shape and no obvious heat damage or cracked solder on the boards.

                  Problem:
                  On first power-up the power LED flashes green about 18x and then stays solid. No backlight or image is present. Click power button, wait 10s for a click and the LED turns red. Wait 1-2s and hit power again and maybe it'll power up fully after 6 green flashes. If it doesn't light up on the sixth flash then the cycle repeats.

                  It seems that if the mainboard power is left on for a few minutes (solid green power, no backlight, no image)...

                  Heathkit IO-4205 Power Supply Caps
                  by eryjus
                  Hello,

                  First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.

                  I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.

                  I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."
                  ...
