Do you have tips on how to learn that ? I right now myself have a r9 280 and the card is working but doesn't give display and if it does after a few restarts, it will crach when it comes under heavy load like csgo or just playing fifa

How did you fix those gpus?

@@mr.stealyourgirl1779 He didn't. This video is 11 months old. His comment is 10 months old. Do you think he went from not even knowing how to use a soldering iron to fixing 6 GPU's in one month? Not a chance. That's not even enough time to buy the 6 dead GPU's, fix them, sell them and purchase new parts, even if he already had the know-how

@@-dazz- thank god we dont have brilliant people like you working for the FBI

@@-dazz- could be possible. I fix electronics for a living. Mostly phones and PCs, just trying to see if graphics cards are worth it.

How do you send power to graphics card to find hot chips???

Would definitely donate if you did!

Yeah! That'd be great actually.

multimeter and that's all. and knowledge about how to use it

It's VERY hard to show how to use years of experience in a short time. Go check out louis rossmanns videos. They are very good. He also tells the gist of it: Many failures have to do with the power delivery. They can be fixed. But on GPUs it's not rare at all to see a dead GPU chip. This will not be permanently fixed by heating those chips. Replacing them requires very special equipment. So if GPUs have a black screen it's a good sign. Artifacting cards most likely have issues with the package it self and therefore are not worth fixing. You can try to bake them to extract a few extra months of usage.

Plenty people do it just the people who make the components don't want you to fix them when they have newer better stuff coming up.

same question ? i dont understand how yt not paying him for videos can we get some explanations why?

How do you measure ESR on such capacitors? They already have a super low ESR that looks like a short on a DMM. I guess you have to remove them, probably can't test them in circuit due to the nature of the synchronous DC to DC converter.

@@haz939 You need a capacitor tester, and optionally a leakage tester. DMMs can't reliably test capacitors. You can get capacitor testers on Ebay for $20. I use this one myself: www.ebay.com/itm/222520569499 You'll need an ESR chart to know what the numbers mean, it won't tell you that a capacitor is bad unless the capacitor is so bad that it doesn't register or shows up as a short. This tester won't show leakage, but you can infer leakage if the capacitance result is wildly out of spec. If you have for instance, a 1500uF cap and it tests at 4500uF, this is far outside the usual 20% tolerance and infers the capacitor is electrically leaky. If the charge that the tester puts into the cap keeps being drained away by parasitic resistance, it will confuse the meter into thinking the capacitor is a much higher value than it actually is. Leakage testers are also useful, but they aren't really made anymore. Your only option is to buy a 40-70 year old unit and restore it, or build your own. In either case you need to be cautious because these leakage testers can operate at high voltages, sometimes up to 2 kV.

Electrolytic capacitors usually don't like hot, but only when they are heating themself. When soldering them in (think about SMD reflow) the heat can be as high as 260 Celsius for a couple of ten seconds. You can check any datasheet about this. So hitting with the hot air for a short time is not so critical. They will explode under current only.

@@zsoltkohler7096 Ambient heat of a reflow oven is very different from concentrated heat of a hot air nozzle. I've seen plenty of people hot air tool capacitors until they popped the vent (radial electrolytics) or exploded (SMD electrolytics).

I've had the aluminum foil trick backfire on me since it insulated the heat, I probably didn't have small enough tip on heat gun though.

how are your repairs going?

if he knew anything about editing, he would have saw that spike in audio

What do you mean...? The audio level is perfectly- *AHHH! WTF!* >_

lets aaad a little bit of flux!!!

@@stonefx83 Ye, first time watching, I was like damn, this man likes his flux..

just the right amount of flux..as said by rossman

A micro-Paul of flux

you can use flux on the solder points so it would be easier just like what he probably did based on the color

borefittyfie: the trick, or the huge knowledge is knowing what and why. that you do with your knowledge and he is brainy.
