      In my personal plastic cup of obviously bloated caps, I count 12 Capxon and 1 Samwha.

      edit: By far though, when people post for help in the lcd world, we see a lot of bad Capxon caps.

        Samwha are of inconsistent quality. While in general they are good, certain production lots are garbage. Capxon are 'replace on sight', I treat Samwha as 'keep if ESR is well within specs'.

          Although I would much rather be drinking a Mai Tai on Waikiki Beach with PlainBill and discussing monitor troubleshooting, I have decided to replace all of my Samwha caps in my Samsung 2053BW, mostly because a) two are bloated, b) they are cheap, c) I don't have the benefit of an ESR meter, and d) I would rather not have to open it up again later.

          I was also very interested to hear Retiredcaps in a previous post refer to FR Panasonic caps. In all previous threads I read, the emphasis was on FM or FC; going forward, I will check for FR first and the benefit of a few extra hours of life. All in the interest of making these more reliable.

          Another item that caught my attention: in reading the above referenced thread on capacitor life expectancy, the author mentioned that over time, caps go down in uf value. That being said, wouldn't it be wise to replace them at, say, 10% over uf value, so that they also last longer? Just a thought.

            Hi Badcaps people,

            Last night, thanks to guidance from this list, I was able to restore functionality to my Samsung 2053BW monitor by replacing all the electrolytic caps. First thing I did was run the onscreen diagnostic, and saw that it only had 4700 hours on it. That's a good number IMO for a $20 monitor.

            But a small wrinkle - I am missing the four little silver machine screws that go into the metal corners of the frame. I suspect my little boys found them interesting when I wasn't looking. I was able to snap the plastic monitor frame back together without them, but I am thinking I should still replace those screws. Can they be bought at, say, Home Depot? Radio Shack? And does anyone know what size threads?

            Any downside to not replacing them? Monitor is now wall mounted.

            Thanks all as always.

              Yes, that is a good deal for $20 with only 4700 hours on it.

              I was able to snap the plastic monitor frame back together without them, but I am thinking I should still replace those screws.
              I have one Acer monitor that is factory manufactured not to have ANY screws holding the cage (that contains the power and logic board) onto the panel. The back panel, when snapped together, holds it in place.

              Different monitors use different screws sizes so there isn't one size that fits all. The best you can do is try to find a service manual for your monitor and see if they have a bill of materials that lists the screw size. Otherwise, I wouldn't worry about it.
