| 1404436 | 2015-07-12 23:52:00 | Yeah . My Samsung Panel was flickering and it turns out a few capacitors were popped. Went to Jay Cars got some caps, and replaced them. 6580 6581 6582 6583 6584 |

It conducts both solder and heat away from the joint, reducing the chances of damage to the printed circuit track and/or adjacent components. Cheap solder-suckers are not very efficient and in the hands of a tyro, that can lead to overworking of the joint and consequent damage to the PC track. Best to use a 2mm/3mm chisel bit rather than conical too as latter loses heat faster. Personally, for two-legged devices I prefer to gently 'walk' the component out by heating alternate legs, then use solder sucker or wick to clean up surplus solder before inserting the new component.

The list here: www.badcaps.net is a good starting point... really you should look up the detail specifications of the originals and make sure you get replacements the same or better. |

| 1404439 | 2015-07-15 22:22:00 | Last time I bought low ESR caps from Jaycar, they were rubbish. Not low ESR at all. Get some from Element14 or RS . Sometimes adding some new(good) solder to the joint can make it easier to desolder . :-) A trick to removing the old caps is to cut them in 1/2 , lift the remains of the can off & that makes it easier to remove the leftover wire leg . |

That kind of approach is only really needed if you are completely rubbish at soldering, in which case you shouldn't be anywhere near them to start with... |

Actually, thats a technique sometimes used by a Electronic Tech I used to work with, he had good excellent sol;dering skills (from years on the job). Not so much with caps, but definitely with old school IC's |

| 1404442 | 2015-07-16 10:19:00 | In the case here with a monitor it does not make sense since in almost all LCD monitors the power supply is a single-layer board which are very easy to work on anyway - to the point that if you have to cut capacitors off to make things easier then you are doing something wrong. I suppose it's fair enough for multilayer boards if all you have is a soldering iron... though you should probably have better equipment if you work on those often. It's easier to do damage with those kinds of methods and I wouldn't recommend them. I prefer a desoldering gun and hot air preheating if needed, and which means you don't have to take a separate step to clear the plated-through holes out afterwards. |
