    About replacing caps on a monitor where some caps look ok

    Just opened up a monitor, and I see 2 out of a 4 array caps are bad, should I replace all 4 or just the 2 bloated ones?



    What about other caps on the board that look ok?

    PS the monitor was turning on for a second and then off.

    if the 4 are the same value then replace all of them - is that a 5th one near it?

      The two upper ones (the bulging ones) are 1000uF 16V and the lower two are 470uF 35V, the one to the upper left of them is also 1000uF.

        replace the 1000uf ones.
        the reason for doing all of them is incase there is a poor batch or something - saves opening it again in a month just to do another one!

        you probably have to buy them in 5's anyway.

            I can see six of them plus two vacant spots.

            If you need I got NCC KYA or KYB (1000 hours) 1000/25, 1500/16 are not available ATM.

              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).

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

              TAGAN TG380-U01 PSU - 5v shorted after replacing caps
              by kotel studios
              Hi

              Recently I got this tagan tg380-u01 PSU with bad caps on 3.3v rail (the line was 2.5v no load!). Replaced them but no go, so I've replaced all of them, apart from some smaller ones and one under the secondary heatsink. Even that didn't help so I've replaced the others. All caps are known good ones.

              Powered it on and heard the breaker pop. Opened it up and saw some smaller caps shorted together. Fixed that up but still it trips breakers. Now I get 0ohms from 5v to GND. Secondary heatsink removed and still a short, even with the PWM IC board removed. All diodes on that...

              Westinghouse L2210NW LCD monitor - bad caps repair
              by momaka
              Here's another LCD monitor repair: Westinghouse L2210NW.
              Quick specs: 22” CCFL backlit LCD, 1680x1050 max resolution (16:10 aspect ratio)

              I got it with a bunch of desktops PCs from a repair shop that was trying to free up space a few years ago. It seemed like a cheap monitor, so I didn't really care that much at first when I picked it up (and indeed it is, picture-wise.) But hey, free is free, so I can't complain. Moreover, it looked clean and the screen didn't have any significant scratches or blemishes.

              Pictures of the monitor outside/case after a brief...
