I found a 22" lcd monitor thrown away in the dumpster, at work. hmm, maybe its a simple fix. people throw stuff out and never give it a 2nd thought. so, I took it home and searched online for any obvious problems. it seems this model (Samsung 225BW) is nothing BUT trouble; I bet every single one has blown caps JUST past warranty time ;( stupid samsung! I'll never buy a samsung monitor after seeing how many people had blown caps in theirs. it shows that samsung does not care about users and cares only about profits, making their products with KNOWN bad caps. sheesh! they'll last about as long as warranty period and then self-destruct after that. STUPID SAMSUNG! here's photos of the psu board and the bad caps that I replaced: its now better than new, after the replacment. and now I'll have 2 monitors at my desk, at work. "how did you get a 2nd display?". "well, I fished a broken one out of the trash and fixed it! that gives me the right to now use it". lol what you see, for the fault, is that it powers up, shows a screen for a short bit and then the screen goes blank or dim. power off and on again and the cycle repeats. this was the first net search hit I found when searching: http://www.ccl-la.com/blog/index.php/repairing-the-samsung-225bw-22-monitor/ it was clear to me that I needed caps. that's all it needed, and that totally fixed the problem. I'm not sure how bad other display vendors are; I have some dell displays that are more than 5 yrs old and still working fine. but many of the samsungs in our test lab seem to have this display problem. seems to indicate that samsung is a brand that should be avoided for lcd displays (maybe other things too, if this is their corporate mentality). |

Yeah they are known to use Capxon caps that are real garbage. Before Capxon Samsung was using Samwha which are like light years ahead of Capxon altough they are not really top of the line. Before my transistor tester arrived I recently replaced mains filtering cap and one that was filtering I think 135V dc rail in old Samsung CRT TV,and when I measured capacity and ESR they were in perfect condition,they were even gold series,and Samsung used those gold series ones for all important filtering. And in the end it looks like the crappy FJL6920 transistor died |

My favourite monitor is a Samsung 226BW that I got for free. It has the same obviously blown caps. |

Done a dozen or so of the Samsung 22-26" LCD monitors in the past year or so. Same story every time. Crap Capicon Caps (say that three times fast). Got a decent stash of them in the bins just waiting for the next dozen or so. And I make a fair amount of $$$ for each repair as well. |
