This past weekend, I get a message from my buddy saying he found a non working dell ultrasharp 19 inch LCD monitor in his basement (don't ask for the part number, I don't remember it), and took the back off and lo and behold, leaking caps on the power supply!
The troublesome caps were all CapXon brand. Three had leaked brown poop out the top, and a few of the others were bulged. Neither of us had any premium caps sitting around to replace them with, but I dug through my bin of power supplies and found one with suitable replacements for the leaking caps. (it was an LIC "400W" one...hahahahahahaha) anyway, we were able to replace the three leaking CapXon KF series (i think) with 2 'low ESR' H.Q. brand caps, and one 'low ESR' ASIA`X, all 1000uf / 10v. This brought the monitor back to life, but I told him to not run it until these could be replaced with something decent, knowing that these are from absolute sh1t brands. So we ordered some good caps from digikey, and the replacements went as followed:
3x CapXon 1000uF 10v -> Panasonic FM 1000uF 10v
1x CapXon 1000uF 25v -> Panasonic FM 1000uF 25v
4x CapXon 470uF 35v -> Nichicon HE 470uF 35v
2x Su'scon 220uF 50v -> Panasonic FM 220uF 50v
Here's the before picture - with my temporary H.Q. and ASIA`X caps (the little ones), and the bulging 25v ones. When we took them off we found that 3 of them had vented through the bottom.
Here's the after picture - lovely panasonic T vents all over
The 2x 220uF ones went in the inverters, which weren't visible in the previous picture
The monitor works with all the new caps, and should for a good long time. After doing this recap, as well as my router, I have more confidence to work on power supplies and maybe motherboards, should I encounter one that needs help.
Thanks to everybody here, I found out all I needed to know without even asking!
