SAMSUNG SYNCMASTER 226BW FLICKERING ON STARTUP MANUAL
syncmaster 206bw / 226bw service manual online. For a 820uF 25v, something around 1200mA and 0.04 or lower impedance would work.Touch screen visibility and operation was great and easy to navigate.
SAMSUNG SYNCMASTER 226BW FLICKERING ON STARTUP SERIES
For a 470uF 25v like Dave has in the monitor, you're looking for something with at least 800mA ripple and about 0.04-0.06 ohm impedance - something like Panasonic FC series would fit this and would be the lowest from Panasonic I'd use. and don't forget to check the diameter and height - you want capacitors that fit in the room you have and not touch the lid and cause shorts or other bad things. Last, look at the temperature rating, make sure they're 105c and ideally 2000 hours or better - lcd monitors can be quite hot in the back, so you want capacitors that can handle heat well. if the datasheet only lists 120Hz or some low frequency, that's a sign those capacitors are not suitable for switching power supplies or other high frequency stuff. Also look for the amount of ripple current they can handle - you want the value listed at 100kHz or anything above 10 kHz at a positive temperature. ultra low esr i'd say would be 0.006-0.025 ohm - but be careful, as some circuits are designed to have some impedance, they won't like ultra low esr capacitors. the capacitors with such value are low esr. Look in the datasheets for impedance below 0.04-0.06 ohm. it's about 2 years old but I certainly won't wait until it dies completely to repair it, it's often more difficult to fix them. the backlight starts to ever so slightly flicker, most likely due to capacitors giving bad power to the inverters or the cfl lamps getting old. On my own monitor on my desk, Samsung T240. Dave would know a lot more about this and it really sucks Dave didn't have enough time to give some explanations in plain English (or better put Australian) about the role of the capacitors in power supplies. some power supply have zener diodes acting as a sort of protection so capacitors going bad can cause these to trigger and turn the power supply off. Bad capacitors can do quite a lot of damage to a power supply - it can make transistors oscillate or overheat and die (and sometimes you have a hard time finding replacement ones), diodes can short. you should definitely fix it if you have the money to get quality capacitors and are skilled with a soldering iron. I'm actually on the other side on this one. Later on there was some argument/lawsuit and scrapped the logo: SamYoung by UCC: SamYoung by them: see At some point, SamYoung also had some partnership with United ChemiCon - that's why their logo was very similar to United Chemi Con's. GSC also did Capsun, Comet, Lelon OC-CON.

(Sacon FZ series are guaranteed to blow up or die, the nightmare of video cards). who was previously known as Sacon who were previously known as GSC. At some point, some series from SamYoung and Samwha were OEM capacitors made by Evercon. There was rumor is Samwha bought manufacturing plants from Samsung or something like that, but Samsung advertises Samwha directly on their site so I guess they have something to do with them.

Samsung made capacitors and they were Samsung: but at some point they sold the business or rebranded their capacitor business as Samwha Samsung likes to use Samwha in a lot of their monitors, because Samwha is also South Korean like them. SamXon generally are OK, but the very low ESR ones (GF in particular) go bad often.So you're probably just lucky that it lasted so long, or you live somewhere colder than usual/you have air conditioning set at cold in the house.
