Samsung Syncmaster 244T - fixed but not.

Re: Samsung Syncmaster 244T - fixed but not.

But I still need to put in as little heat as possible into the capacitor/s, yeah?
This is my main worry; that I'll stuff it up with too much heat.
I'm more familiar with soldering connections in electrical looms in cars (I restore old cars as a hobby - Valiants - the Aussie type; I just noticed you're an Aussie also so you know what I'm talking about) where excess heat melts a bit more of the insulation and sometimes you need to clean and re-tin the soldering iron when some of the melted plastic gets on it. No big deal; but here, I'm finding that heating the cap wire and the PCB enough to melt the solder a bit worrying. Although the iron is set to high (and it's quite hot enough); it taking a second or two isn't quite the case (probably due to my inexperience).
Any further tips in regard to this (yeah, I guess I'm after a bit of reassurance that I'm being paranoid).
It's a new skill and I need some hand-holding (in a purely hetero way)..lol.
Thanks for your time and patience.
BTW. Where in Vic are you located? I'm in the Dandenongs, south-east of Melb (Cockatoo).

i can't say that i have ever seen anyone overheat a capacitor before, though with my luck it will now happen. i crank my iron up and it is only on a leg for 3 or 4 seconds and that is all. since you will need to expose some more copper, it will take more heat and time to get it up to temp to take the solder. still, it is normally quite hard to damage the trace in a case like you have in front of you now. once it is tinned, it will require less time with the iron to get it up to temp. a little flux might help you with the flowing of the solder too.

if you can get a hold of a scrap board, have some practice removing and reinstalling some caps, just don't practice on a pc, as they are always a pain.

i don't have any valiants here but i do have a bronco and a gemi to restore.

i'm quite familiar with cockatoo, my friend owned the internet cafe and computer repair shop that was up there. i'm out in blind bight, which is next to tooradin, so about 45 mins from your direction.

Well I will reassure you that you are in fact paranoid lol. Capacitors are probably the most robust component on the board. So don't worry about overheating them.

unless you overheat one changing a eeprom ic and it explodes lol (smd can type) certainly makes you jump.

Re: Samsung Syncmaster 244T - fixed but not.

Good to know re the capacitor's ability to take some heat.
Also, good idea playing with another circuit board - I'm sure I have something lying around (I always get friend's old DVD players as they are sometimes good for still playing CD's so I have some tunes when I'm in the garage; and a remote. But I'm tending to use my phone nowadays)....
I remember the computer place on McBride st. but I think it's gone (or I'm being senile again).
I once bought a Valiant in Blind Bight for $50 - and drove it home (It was still registered for another 6 hours...lol) - bought for parts - some of which are still in one of my Vals today.
Well, I'm going to wait for the bits and pieces I ordered and will post back when I (hopefully) fix the monitor. In the meantime, I have a $182 LG LED 24" monitor taking its place (ordered Wednesday, arrived Friday; from eBay!). Super flimsy (the case still flexes at the back where the Vesa plate is screwed on); and I know they're not as good as LCD but it has a pretty good picture for these old eyes............
