G+_Tyler Pearson Posted May 28, 2016 Share Posted May 28, 2016 https://m.youtube.com/user/rossmanngroup? I was just wondering around youtube and came across this guy. He owns a repair shop and does component level repairs on motherboards. While i may never do this type of repair i found it interesting. I personally think that laptops have become so cheap that usually a repair like this would be a waste based on some of the prices I've heard but i guess there is some business in it. Especially if the laptop is out of warranty and 2-3yrs old but it makes me want to get a few broken laptops for free or cheap and start messing around for fun. https://m.youtube.com/user/rossmanngroup Link to comment Share on other sites More sharing options...
G+_Eddie Foy Posted May 28, 2016 Share Posted May 28, 2016 component level isn't as hard as one would think. (still not that easy) but knowing the symptom, and part numbers you can usually find the offending device. desoldering can be an issue. PTH are a bear. smt is another fun one.

G+_Ben Reese Posted May 28, 2016 Share Posted May 28, 2016 I made a video of me replacing a few electrolytic capacitors on an old motherboard hoping to resurrect it. But, the board still won't boot. There are 2 more caps that are bulging and probably need to be replaced, but I didn't have the right size. Plus my 30w, $5 iron was terrible at desoldering. ? Oh, and since it didn't actually fix the board, I never posted the video to YouTube lol. Link to comment Share on other sites More sharing options...
G+_Eddie Foy Posted May 28, 2016 Share Posted May 28, 2016 Elect caps dry out over time. If resurrecting old electronics, its best to use a variable transformer (variac) and slowly turn the voltage up, like from 20V to 120V over 12+ hours. Desoldering without a good purpose built vacuum pump iron, is near pointless. Though the chipquik stuff works rather well, but also rather pricey. (I got a free sample from them and do like it.) For through hole, just cut the leads and regular iron with wick and tweezers and do each lead individually. Link to comment Share on other sites More sharing options...
G+_610GARAGE Posted May 28, 2016 Share Posted May 28, 2016 Makes sense if you have old hardware that can't be upgraded nor replaced. Link to comment Share on other sites More sharing options...
G+_Ralph Mills Posted June 3, 2016 Share Posted June 3, 2016 I see that Louis Rossmann videos are about repairing Apple products. The initial purschase price and/or cost of replacement contribute to the repair or replace decision process. Link to comment Share on other sites More sharing options...
