    Samsung 225BW Monitor Caps

    I need to replace two bad caps in my monitor.
    The two bad caps are the same: 820uF, 25 volts, 10x20mm, radial

    There are multiple caps I found on mouser.com but which ones do I need?
    Low ESR? High Frequency?

    I found this one. Could this be it?

      Welcome, primoadamp!

      You are correct about these capacitors needing to be low-ESR (low-ESR usually means they are high frequency units) such as Nippon Chemi-Con KY (or KZM if you can get them) or equivalent.
      My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

          So the low esr caps are the ones I need for this monitor?

              I suppose the original ones were Capxon.
              I exchanged similar ones with 1000 microfarad ones made by Sancon which, while not being Low-ESR, had lower ESR value than the original Low-ESR Capxons. Works fine anyway, because they are just filtering caps.
              Pay atention to temperature rating, they must be rated at 105 degrees celsius because they are quite close to a double-diode heatsink.

                  Replacement caps for Samson Resolv studio monitor 65A Amp board.
                  by black6host
                  Good day!

                  I have a Samson Resolv studio monitor that has no sound output. I've opened it up and found two caps that are bulging on what I believe to be the power supply section of the amplifier board. The board is marked Resolv 65A AMP V1.2. The caps in question are YUSCON, 2200uF, 35V, 85C temp and have markings of RA(P) and are 16mm x 25.5mm tall. I've attached the schematic and the caps in question are C5 and C6. I'm assuming they are low esr caps. I've tested both caps and they test low uF, nowhere near 2200uF.

                  I'm going to replace the caps and I'll be the first...

                  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...

                  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:

                  Dell monitor PSU vs Dell laptop PSU
                  by keepread
                  Hi there!
                  Someone gave me their old monitor, it's Dell S2715ht.
                  The owner was using it when his PSU began to smell and then to smoke. It literally began to melt. He turned the monitor off, pulled the PSU, and ditched it because it was smelly even after it cooled. So I got the monitor but not the plug.
                  Now, I tried to bring the monitor back to life, by plugging one of my many Dell laptop PSUs. They are of the same 19.5V, and the wattage of the laptop PSU is higher than that which the monitor is rated for. Visually, the socket on the monitor seems compatible, and the plug plugs...
