Hi Alex , I'm calling all the way from South Africa and I enjoy watching you meticulously taking care of your work and I love it. I'm your fan and feel great to say so. I have a Onkyo Amp and it's working fine after I took it to the agent 2 years ago. I bought it as used and it worked fine for the first 5 months then one morning it suddenly didn't produce any sound at all . What I noticed then was that the speaker icons didn't appear on the display. I was told that I need to apply heat on the BGA chip and I did so . To my surprise the relays clicked and the sound was back , the icons for the speakers also appeared. But Everytime especially in the morning when I switched it on it would do the same and had to apply heat again. So now it was taking longer each and every attempt . If I leave it on for the night no problem. So like I said I ended up taking it to the agent and they replaced the HDMI board and it's still working fine. I have the old board and took it to the local tech to do the BGA reballing or something like that. It came back and worked fine after reinstalling it. But after a while it did the same thing again. Took it out and put back my new board and it's okay. I called the technician and he's said he only applied the solder flux then reheated the chip. I thought he was going to take out the chip and put fresh solder balls unfortunately he didn't do that. After watching you working on the ics I wanted to find out if you can help me out with that and how much will it cost. The chip is fine because everytime you heat it up it works. Please help I want to use the board on a customer Amp it uses the same board and it's burnt badly. PS .I asked the agent what was the cause of the chip not to work and he said the balls underneath the chip shrunk after a prolonged use and the heat added to the balls shrinking.
Really amazing how you fix things, yes you have the tools but you certainly have the skills to pull off a perfect repair like this. Keep up the great work Alex
You could always go take an IPC-7711/7721 class, it's a bit expensive but it's the global standards for class1, 2, & 3 circuit boards. The cert is good for 2 years but the knowledge will stay with you
Sounds like a weak pad alright ... I mean I have no idea but a friend recently troubleshooted a board and the culprit was a bad pad for a transistor. One of the leads on the transistor was not making connection because of it. When he removed the transistor to test the pad just came right off.
A lot of boards like these have weak pads due to how thin the pads are and by being cheaper boards they usually don't have very good epoxy holding them in place. A little heat on cheap boards will disintegrate that epoxy
I was wondering how difficult it is to source Tristar ICs right now? They seem to be generally (and thankfully) available, but mostly listed as out-of-stock... Chip shortage seems to affect those too.
Can you walk us through how you transitioned from web design to fixing electronics? How did you ramp up your learning to do this as your day job? I want to dabble in something like this but it seems too hard to transition.
today my equipment paid for itself.. first day! I had A1706 MB pro I sold customer and put a new battery in it, turns out battery was defective. replaced battery, still wouldn't come on. Was about to refund the customer, decided to take logic board out and look under the scope. small particle between contacts on the battery safety flex cable that goes to the daughterboard. cleaned it out and to quote Alex "thats it, the job is done". unfortunately, I had to put it all together. damn where is a big boss when you need one.
Well .... If you ever needed proof of better than Factory.... You just seen it here .... Well done Alex and Big Boss ... Another excellent repair job and a brilliant upload... Big thumbs flying high from a galaxy far far away called Ireland ☘️👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
@@user-kr8tp3ko8z yep exactly, the UV starts the cure, then adding heat reduces the time for a final cure. The solder mask we use at work though isn't a UV cure, it's just a straight 220°f bake for an hour
Maybe it's the manufacturer way of securing the connection: more "anchor" points = more strength. Also, there is a possibility to use the same connector with future boards, where they could use that pin for a different purpose.
There isn’t a clear answer for this. Its just how they design them sometimes. However there is one reason. Many times you will find ground between lines that use different voltages. The ground pin in between separating them protects the higher voltage from going to the lower voltage line. This is common knowledge to people who design circuit boards. Kinda why Louis Rossmann has made a couple of rants on macbooks not following this common knowledge.
Hi amazing channel. I would love to hear your opinion on my problem. My 9 year old son gpu "Rx 570 8GB" suddenly started having artifacts and drivers fail, this happened after we moved, not sure if that has to do with it. I did find a temporary fix. If I push the gpu and find a sweet spot and hold still while running and artifact disappear and gpu's works fine. So I ended up placing some type of support under the gpu and it's been working for more then a month. The pcb of the gpu is being bent because of the support "I use a broken wooden ruler lol" that I placed under, there is any way to fix this gpu ? It's worth the fix? Thanks
It's often the case that GPU circuit boards flex a little above the end of the PCIe connector (due to the weight of the heatsink/fan assembly). This can cause connection issues with RAM chips in this location, which is probably what you are experiencing. You can leave it running with your support bracket if it's working that way. Make sure your bracket is secure and won't fall out if disturbed. If you have problems later, you can try having the RAM tested and the failing chip reballed (resoldered).
So, since the big bang, we humans have only been here in that time frame of the last 300,000 thousand of those years, a mere drop in the bucket as they say. I'm only talking about modern man's existence. And there we were, all bunched up in Africa until someone said, "Hey, I'm going to go out and explore the rest of the world. A few followed and the world got populated. Then, Mr. Alex came along and as they say, the rest is history.
I love how he says "we did it". It makes me feel like "me watching" was apart of the success. Such a great channel.
We are. Ad revenue might not be millions but for a small buisness it could be just enough.
Yeah every time he says it
I say YES YES WE DID 😅
I also love when he says: the short is gone.
The way he explains throughout the process, really makes you feel included. Makes you listen :) Awesome stuff!

A good Coffe and a NorthRidge Fix video is the best way to start a good day
True

Having the Necessary Tools and Skills for your own Repairs can Always turn into A Business
That grinding pen is amazing, you make it look like magic all the things you've fixed with it
Watching you fix things is fun
Grinding that super tiny strip at the top of the ripped pad was impressive. In an alternate universe, Alex is like a brain surgeon or something.
Outer traces aren't bad to do at all, it gets crazy when you have to do repairs on the inner layers of a circuit boards lol
Very nice work, testing and inspecting the board first spared a lot of more work afterwards ...mostly. Greets
Inspiring skill and awesome tools. I wish i had a skill and tools like yours Alex. Keep it up. Keep on inspiring.
You could always go take an IPC-7711/7721 class, it's a bit expensive but it's the global standards for class1, 2, & 3 circuit boards. The cert is good for 2 years but the knowledge will stay with you
nice thing about it, you can buy everything he uses. with practice, it can become just as doable for you.
your work bench has seen better days
Nice work. How did the graphics card end up from the last video?
Stronger than factory! Btw there was some audio clipping on the last clip, bit ouchy.
Man, you are like a surgeon of eletronics. Congrats! 😁
Hi 👋 sir big fan from Sri Lanka 🇱🇰
Trabalho muito top. Exemplo de profissional
Amazing job as always. How do you get rid of the glare?
That’s why you make the big bucks. Great job you are so talented
Hello
What's about yesterday GPU did you fix it or the GPU is not fixable
hello sir. I am big fan of your work and I also repair my own laptop. super thanks

Where have those trace pads been my whole life ? Just ordered some
Wonder if can fix surface not charging one day 🙏
Very nice work
Quality work
experienced in microsoldering as always
what about that msi 1070 ??
are you fixing car audio systems as well?
a nice job like helu from raouche
Very quick 😌
I have a Acer H7850 Projector that needs repair on some traces on the control panel can you fix it
And apple say repair shops can't do this work.. shocking
Hi everyone, I have a question. How we can get full test form the pc moderboard health? And how mutch we can trusted to result?
Good as always!
Awesome job bro keep rocking bro
Better than factory 👌😆😎
Hi I want ask you about internal bios in IO Who can I know that ?
Very nice

Watching Alex soldering is like watching a Rembrandt paint
Well, we know Alex's D&D class: Metallomancer.
Is your uv package metal or ceramic
Good Job
Well .... If you ever needed proof of better than Factory.... You just seen it here .... Well done Alex and Big Boss ... Another excellent repair job and a brilliant upload... Big thumbs flying high from a galaxy far far away called Ireland ☘️👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
Good job,,. Awesome
I thought the instructions for the TriStar Tester indicate that the device is to be off, completely powered off, when you do the testing.
The device is not on at all, it's completely disassembled.
As soon as pad strips was said I knew it was gonna be number 2
At least he doesn't have to hand cut them, thank goodness!
MASALLAHH
Do you change phones battery?
nice Vedio ☮️ 👍
Awesome 👍
This might sound stupid but why not just use the hot air to dry the solder mask instead of the UV lamp.

Hi I am from India .So please i have request you Can you provide me graphics card onboard item such as ( Capacitor , Resistor , Worm and other.
Hey Alex, how can I get in contact with you.
I really want to show you something another guy has worked on and after that was handed to me.
Why do connector pins share circuits instead of just having less pins on the connector?
Maybe it's the manufacturer way of securing the connection: more "anchor" points = more strength. Also, there is a possibility to use the same connector with future boards, where they could use that pin for a different purpose.
There isn’t a clear answer for this. Its just how they design them sometimes. However there is one reason. Many times you will find ground between lines that use different voltages. The ground pin in between separating them protects the higher voltage from going to the lower voltage line. This is common knowledge to people who design circuit boards.

Usually supply pins are shared for better power distribution and also for noise shielding among adjacent channels.
