CHIEFTEC CFT-56--A12S Dead Short
I replaced the large 470uf 450v cap in said above PSU. I'm just learning and I might add the hard way most of the time. Anyway, I saw the original cap bulged on top, pulled it and found it bad. I should have checked the darn fuse too... but didn't until the new cap was in and still no start. Sooooooo.. now I don't know how to check for a short or even where to begin. Thought I'd start here on BadCaps for some advice before I toss my 7 dollar cap in the trash.
Thanks..

I have them ready to mail back.. but not sure that's what I should do. I'm trying to figure a way to make sure all his future customers know he's theft by deception..

Re: FAKE Rubycon 1800uf 6.3v MCZ
I suppose I should chime in here..
I have some experience re-capping.. but no means a veteran. I'm learning. All my caps had come from Mouser so far EXCEPT these. Some may wonder why fleabay... not know no better... 'till now... but knew enough to see something wasn't right. I'm sure there are some honest cap sellers on the bay though. Yea, I intend to return them... with negative feedback. The guy can't count either.. sent me 21 caps and ad was for 25.
I have learned much from BadCaps folks and want to thank ALL who help...

radiant p1510 P.O.S. recapped and no boot
Hi..
I've replaced all the 2200uf 6.3 caps (11) with sanyo and it won't boot. The remaining caps are Rybycon ie 1000uf 10v - 1500uf 6.3 - 1500uf 10v and i wasn't sure I should pull them to test because I don't have new replacements for them. A little help from the "knowing ones" greatly appreciated.
I don't know who actually mfg this mobo for Radiant either. Info is scarce.
Thanks,
Don

Re: Rubycon Caps
Thanks again for the info.. every little bit helps.
Soooo.. is 198uf to 200uf acceptable for a NEW 220uf cap or should I return them?
I have other caps of different mfg and values, some of which are over stated values, and like these, under. I'm just trying to get a grip on all this, as I'm a newbie..
I have successfully repaired about 30 laptops, and around 20 LCD monitors. Mostly Bad Caps, and a couple CCFL fixes. I'm hoping to learn enough to open a small business in my little home town because there is nobody around...

Rubycon Caps
I just got some Rybycon caps 220uf 35v and they all read 200uf .3 ESR
(Atlas ESR70 test meter)
Are they OK ?? I'm trying to learn. I don't know yet, the min max readings allowable and haven't been able to find a general kind of chart or something.
Should I be looking at Nichicon from Mouser and if so, and I wanted to use say 105 degree, there's a boatload to choose from and I don't know how to choose yet... My amature knowlege showing up here :>)
Any help appreciated.

Re: AOC F22 Power issue.. Here's one for ya..
Thanks Agent24..
I'll work on some better shots f I tear into it again.. The monitor is still running again, with just a flicker now and then..
I think I blew the fuse when the board slid out of my hand and touches the metal case, discharging a cap. I heard it discharge. Difficult working with a broken finger.

AOC F22 Power issue.. Here's one for ya..
First, [COLOR="Magenta"]MANY[/COLOR] thanks to all here at BC.. There is a wealth of info here and some really kool folks!! Their posts have helped me tremendously in my humble learning.
OK.. I have an AOC F22 monitor that, after recapping, goes (DID) to black after a 2 - 3 minutes or so, quicker after it's been on and powered down with the button. BUT.. it gets better here :>)
I used Nichicon.. Panasonic and Rubycon
1. the two tall 680uf 35v was all I had
2. the 22uf 50v checked OK so I left it.. didn't have a new one
3....
