Rithy58 Posted April 11, 2012 Author Share Posted April 11, 2012 So my monitor has been flickering and such and because it's a Samsung SyncMaster 226BW, I knew it is the capacitors on the power supply. A little googling confirmed this. This will be my first time replacing capacitors so I'm quite new to this whole thing. I don't know what I need to buy. I think I got everything except the soldering iron. Some suggestion would be very nice.http://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=451b1fc637If you can post up the part # from mouser that I need to buy, I'd really appreciate it.

Anna Comnena Posted April 11, 2012 Share Posted April 11, 2012 Wait, not only are you repairing modern electronics at home, but you expect some of us to know what we're talking about? Consumer electronics are not really designed to be repaired by the consumers anymore, gotta love forced obsolescence.I'm sorry to be a downer but I don't think you'll find help from any of us first hand here. Gwen maybe, I know she likes tinkering with stuff, but even then I think something like this might be too specialized. Any hobbyist sites or samsung/monitor sites out there that you've found? They might know more of the details on what exact capacitor you'd need and the best process of replacing it. Link to comment Share on other sites More sharing options...
Homicidal Monkey Posted April 11, 2012 Share Posted April 11, 2012 its probably going to be impossible to do. A monitor is going to have multiple capacitors, also capacitors have different thresholds and discharge rates. It is totally possible for the monitor to have custom-built capacitors or capacitors of varying rates/thresholds.Also, if its the powersupply, I'd suggest not touching that.source: I've shocked myself on a 300v capacitor once. It hurts. Also I've taken plenty of E/M classes Link to comment Share on other sites More sharing options...
Rithy58 Posted April 11, 2012 Author Share Posted April 11, 2012 I know the capacitors and stuff. 2 x 820uf 25v and 1 x 330uf 25v. I just thought maybe a few people here know about it. I don't think it's hard. It's just, I don't know what type of soldering iron I need. Link to comment Share on other sites More sharing options...
Homicidal Monkey Posted April 11, 2012 Share Posted April 11, 2012 have you opened it yet to see the size of connectors to the capacitors?btw, this thread still reeks heavily of ishygddt Link to comment Share on other sites More sharing options...
Marsh Posted April 11, 2012 Share Posted April 11, 2012 If you are doing this to learn or have fun then more power to you.Otherwise, monitors are fairly cheap and i would just buy a new one. Link to comment Share on other sites More sharing options...
Kemerd Posted April 11, 2012 Share Posted April 11, 2012 Will someone actually help him? Instead of yelling to him about how it's impossible and blah blah blah waste your money on a new one.Ok, first of all. Get all these things. Go to radioshack.1x Spool of Solder1x Soldering Iron (Try at least 45 watt if you want to be able to get a good, easy melt.)1x Desoldering Iron (45 watt again, for best results. You need a desoldering iron, a desoldering wick ain't gonna cut it.)1x A good, steady hand.Those are the tools now. First of all, find the capacitor that's at fault, get a new one. Second of all, use the de-soldering iron to take off the solder from the old, broken capacitor. Place the new one in, and solder it in. Be very careful now. Watch the polarity and make sure the solder isn't touching anywhere it shouldn't be.Look up on google how to do a good de-soldering, and soldering job. Also, I still advise to go to radioshack. That's where I get all my stuff. (I'm a hobbyist.)This is my desoldering iron.

Gwen Posted April 11, 2012 Share Posted April 11, 2012 I wouldnt reccomend touching capacitors in a TV/Monitor unless you know what you are doing. I helped out a friend that worked at tv repair shop for like a day, and that was one of the things they warned us to stay away from. They store enough power to seriously cause damage if not death if you are not careful. Link to comment Share on other sites More sharing options...
Rithy58 Posted April 11, 2012 Author Share Posted April 11, 2012 The capacitors I'm "touching" is only 25v. I did opened up my monitor and I saw the three capacitors that is bulging out with the electrolytes coming out.I'm ordering the capacitors now and my cousin have a soldering iron. Now, do I need the solder and what kind? And what is a desoldering? is it like a tube that you squeeze to suck up the old solder when I melt it to remove the old capacity?Sincerely,Rithy Link to comment Share on other sites More sharing options...
Marsh Posted April 11, 2012 Share Posted April 11, 2012 @Rithy58:> is it like a tube that you squeeze to suck up the old solder when I melt it to remove the old capacity?Yea it basically just sucks up solder. Link to comment Share on other sites More sharing options...
