Driving dc inductive loads like this motor causes decent back emf across the contacts of small relays when they open off causing them to wear out really easily. If you put a flyback diode from negative to positive on the output to the motor, you will get a few more years out of if before it wears out again. Love the videos by the way!
I highly doubt that isn’t already populated on the board. It would potentially kill other components on the same power rail, which would happen mostly under warranty since it’s not an exposure failure. No company wants that.
Never get tired of listening to the words Alex exclaims when he fixes a problem-WOW!! Please do a primer on steady hands for those spastic ones among us.
If you sent it back to the company for repair they'd probably go like "we have to replace the whole board, that will be $1k, thank you". And that's assuming they'd even bother doing board level repairs.
U shouldnt cry at a company for doing this, its their right to not focus on microsoldering repair, its totally different to manufacturing. U should cry at a company for actively blocking 3rd party repair, like blocking chip or component supply or locking parts in the device by software.
no company repairs such things, because it's unprofitable.
looking for a broken component and hiring a technician would cost the same as a new motherboard.
You shouldn't assume they do board level repairs, most companies don't think it's worth it to find skilled enough people to have component level repairs. They'd just replace the board
Corporate waste!
so u have to buy new.
no way
@@bornagain2641 Read my comment then you know your answer:)
Thank you Big Boss for reassembly, and thanks Alex for fixing that relay.
Inside house job is the best, specially, when fit in the daily job. Nicely done! Minimal E waste, I like it.
"Thank me!" 🤣🤣🤣🤣 I always learn when I watch. This time I learned that low melt solder stays soft for up to 10 seconds. I also learned that low melt solder gets brittle. These are good things for me to know. Thanks Alex.
Now they'll start sending in tape dispensers for you to fix!👍🤠
I would love some steady hand techniques. I shake like a leaf sometimes under the microscope.
Looking forward to for the video about steady hands
It's clear to see the original relais has a cold solder joint (top right pin at 4:03) I think this was the problem not the relais.
Way to go nice save 😁😁👍👍
Better than factory!!!
May I ask what temperature you use when using low melting solder, can come in handy for my to, Thx, and many grts to you, and your family from the Netherlands 🫡
Awesome job
Now I must go and listen to AC/DC's #ShotInTheDark 😊
Losers use emojis and dumb ass tags.
You would have run new soder on the rally it would have worked perfectly is not contained properly that's why
Any reason why you didn't test the relay first?
Awesome ✌🏻✌🏻✌🏻
How much did you charge for this repair ? Thanks for the vid
give bigboss a magnetic tip screwdriver :D
no low-melt solder when soldering back the component because it may fall out of place when the operating temperature rises.
Alex knows that. He's made that point on several occasions, including in this video at the 8-minute mark.
No one cleans relay contacts any more? Lost art from automotive points and condenser days?
buy big boss a magnetic screwdriver for xmas
Get Big Boss an Electric Screwdriver..
when's big boss channel
He needs an ltt screwdriver, smooooth ratchet
segundo viasualizador 🙂Do Brasil
Did you order Exidited Service to getthis moved to the top of your Service Queue? 😂
If you couldn’t repair it, I was going to suggest to send it to an expert lol
Tjis is why John Deer makes everything impossible to self repair becuse if we could service our own equipment theyd not be able to be a predator.
Did you paid yourself for expedite service?... LOL
First to view again 😀
I noticed 2 cracked solder joints on the board edge at 4:04. Maybe even resoldering relay pins have helped to cure the problem?
There were no crack on them, just a little fibre.
Yes, I noticed that too.
@@TheMystikal82 Yes, you can clearly see it is fiber as it moves when he touched it.
Love watching big boss disassemble and or reassemble. Great skill and patience. Fine troubleshooting and repair Alex. Absolutely great.💖👑
As much as the focus is often on Alex's skill, we shouldn't look past the skill that Big Boss has - it is a huge enabler to the success of the whole endeavour.
I fix alot of things myself, not at the level Alex do, but i do try :D and i am also lucky more times then not. One of the things i hate the most is the disassemble, there is always plastic tabs that break so easy, a hidden screw under some tape or other stuff you first notice when you almost broke the pcb or something else.. and cables you need to disconnect for some lcd screen or something..
To me the disassemble is just as hard as the fix, not always of cause, but sometimes you fight with the damn disassemble for 30+ mins just to replace a stupid fuse you couldnt access without the disassemble..
So even i am sure some people see Big Boss as just a cool name for the low end easy job, i feel it isnt always easy.
For sure a nice team :D
Nice video Alex.The machine in the photo looked much smaller and i thought 1500 was a lot,but in business it's really about doing the job better and faster.That machine certainly does that.Then when i saw the real one ,i thought heck no wonder it cost a lot it's BIG and heavy with a lot more components to it.That means it also has encoders to measure the tape length and if it starts giving you odd length tape pieces it would be the disc that goes through the sensor has got tape fuss on it.We had one where i worked that i fixed but a different brand and smaller.big boss has a great memory.
The first time a customer didn’t write a note of what happened to the machine and no invoice was sent as well
Fixing Electronics requires so many skill-sets including the Art of soldering. It's not something that would lend itself to the employment of apprentices. You gotta hit-the-ground-running when you start doing it and have a firm base of electronics theory and practical soldering skills already. It's not for everyone. I'm so glad you are the expert....lol
there are very few people who share what they know with people by telling them like you, and teach electronics! thanks to you, we have learned a lot and we are learning that you are well, thank you so much.
Before you replace the relay...
I thing the top left solder seems a bit off ???
I bet the customer had "VIP Expedited service" this time 🙂
steady hands lean on the table
How strange! I was actually going to comment on how I look forward to seeing you repair a personal device on your last video and now this pops up 😅 brilliant result! Look forward to more 😊
Very nice, it is so nice to fix your own devices. I love that too. Great job. Thx for that video
Alex said he “took a shot in the dark.” No, that was an understatement. It was an experienced troubleshooter’s analysis of the most likely root cause. And a great example of the excellent teamwork between Alex and Big Boss. Happy Father’s Day to all of you.
I can't imagine ordering and waiting on a relay without at least checking the ohms on the coil or testing its activation, especially before making a "shot in the dark"
thank you for writing this
this is what I was thinking of 😇
Alex is the best 💪
If sometimes you hear clicks and sometimes you don't, a relay is the first place to look. But I guess it was a shot in the dark in the sense that he didn't actually test anything, and the problem could be in the circuit that controlled the relay, and not the relay itself.
Can't be certain but it looked like there were dry joints on the relay coil pins - the ones near the edge of the board. Would explain the intermittent nature of the problem. Would also mean it worked fine after the new relay was in because of the now 'better than factory' joints 😀
100%
Yes. Could it be because it has a moving part generating vibrations every time it functions?

R&M on business equipment is always important to keep everything rolling. Good job Alex, I'm sure Pops will be happy having the tape dispenser running again.
Happy Father's Day to everyone there.
Same to you. Happy fathers day 🎉
I think the original fault was a dry joint on the first solder point you showed at 4mins 21 sec. It had the crusty rough edges you find on dry joints, and these are familiar to TV engineers of the recent past where a lot of heat is generated in the joint due to the high currents in power supplies. I always look for the black ring around the solder joint using a magnifying glass, followed by a reflow. This usually resolves the problem. Perhaps you agree?
Wait! was that a solder sucker??? Great repair! Paper tape is way more awesome than that clear junk. As a know-it-all side note. With clear tape everyone uses 2" wide, which is not made for hand taping. even though everyone uses it. 2" is for automated taping systems. for hand taping you are supposed to use 3". But paper tape is far superior.
The relay clearly exhibited fractured solder joints. I would bet a cup of coffee that removing the old solder and then flowing new solder onto the joint would have fixed the issue.
Big boss enjoys the moment of truth 😂, حلو حلو حلو
Bravo.
Great Job.
It might be possible to repair the old relay. Can it be taken apart? If so, try cleaning any pitting on the contacts.
I use to fix those all the time... FYI use Dawn Dish washing liquid to clean the tank brushes use the PINK DAWN
I've been in this situation when my tv broken. Fuse keep blow if replace with new fuse. Search for power supply board so expensive online. Replace 3$ triacs that faulty fix it. My first repair attempt successful. So glad😂
Who can't test a relay in circuit? Hell even out of circuit... Still won't pay for a proper solder removal gun? Ohhhh so you can pitch your wares... not your abilities.
"A" not "And" in the title but otherwise Great Video
Fixed. Thanks
14:10 Hi Alex,
Have been enjoying your videos of the incredible microscopic work you do, and am looking forward to when you do a video on steadying your hand whilst working.
GREAT !!!!! NEED TO FIX MORE THAN JUST BOARDS. SHOW AND REPAIR ANYTHING ELECTRONIC RELATED GOODS ????
It's not an 'shot in the dark', it's the very experienced Alex. My question is why does your big boss doesn't wear anti-static wrist band while working on motherboards?
I can understand that tape being more resistant than your average packing tape (since the glue soaks into the cardboard), but I've seen packers use (good) tape dispenser guns, and it literally takes them less than 2 seconds to do each side (3 to 5 seconds per box, tops), so I really don't think that's _faster._ Probably more secure (assuming you can't get the same type of reinforced tape in a roll that fits dispenser guns - it would be tricky to use wet tape for that), but I can't see it being faster.
I tell you big tech companies one thing. If you ever sell one of your devices to Northridge fix you won't make any money with repairs on it. Mighty Alex will not go to sleep until he has fixed (and made it better than factory).
Get that man some powered screwdrivers lol
Great work! Would love to see steady hand techniques, since I can always bring helping hands tool!
The manufacturer, if they fixed these things at all, would no doubt only want to replace the whole motherboard if even that, and charge you the ridiculous amount even though a small and cheap things was broken and easily fixed.
I used to have steady hands and was able to solder very well. Unfortunately now they shake to a varying degree, so any tips on how to stop them doing so would be very much appreciated. Thanks Alex for these informative videos.
It could have been an expensive repair. Disassembly, testing, expedited service fee. :)
The relay probably drives the motor. A trick used on car points was to put a capacitor across the points to stop arcing and make the relay last longer. Another trick is to put a 12 volt zener in series with relay driver fly back diode to make relay turn off faster.
You should try the solder sucker that has the soft silicon tube end rather than the hard plastic. You can get it flatter to the board even with the iron there. I personally hated using the hard tip solder sucker, hardly ever worked unless I heated one side of the board and used it from the bottom side.
You’ll get carpal tunnel syndrome using a hand tape machine like that boss!!!!
for tht components solder sucker with silicone hose at the tip like engineer ss-02 are better, you can put it right on the tip of your soldering iron while heating up the joint and create a seal to the pcb. they suck up solder much easier then the ones with ceramic tip.
There good machines we use them at work for the tape for boxes we just replace the PCB when it fails as not worth the time of trying to diagnose the issue to the company using the serial port at the back you can also have it linked to automatically dispense tape required.
For that kind of solder joints, better use dessoldering gun station than hand pump. With this tool, taking out such kind of relay is a matter of seconds.
Hello. the problem is the type of relay and how it presses on the contact points. relay presses too far down on the contact pin. The others are that the relay does not have a suppression capacitor which should reduce sparking between contact points. with a relatively large motor, the motor will wear out the relay very quickly
Big Boss is the man, he can take apart anything and assemble it like if it was nothing
+1 for the steady hands technique! Help me Alex 😶🤣
OMG this is crazy such a great stuff I've never heard about this before.
shaky hands.
stop drinking coffee, smoking cigs and weed, and no alcohol
Good fix but I'm utterly stunned how a tape dispenser can cost $1500 ..it's crazy
And why you even need it in the first place. You can get a good handheld manual tape dispenser for $15.
@@I_Evo it speeds up big bosses work and is more efficient than manual tape dispenser in a long run. So it’ll pay for itself little by little
@@Syntappi I'd like to see the time-motion study on that hypothesis.
@@I_Evo *Get out your cheque book. I'll wait...*
When you can fix your own machine, you are a real BOSS!
That's where the joy of repair starts - successfully repairing something yours. Great feeling! 👌😘
So the customer request (and got) expedited service I guess? 😁😁
if you look at the relay inside you will see carbon created by sparks, this is what makes the relay stop working
If I would be you, I soldered a relais foot. Easy to replace later if it brakes down again.
Fine trouble shooting Alex and happy fathers day to you
14:08 What kind of tape machine is on the table? Looks like it is for clear tape? Thanks.
i think i would be better if Big Boss av electric power screw driver to remove and tight the screws
Was the customer happy? How much did you charge him?
shot in the dark - and you're to blame - you gave packing a bad name
it looks like one of the relais coil solder joints where cracked i see similar problems every day working on german dishwasher / Washing machines and its 95% a fix with just solder all solder joints of those relais again
Can’t find the solder sucker on your page
still think BIG BOSS should have his own channel
Good job😁👍, happy fathersday👊
The contacts on the relay just gets a layer of carbon on them over time. You could even pull it apart and clean them carefully and it will still work unless the coil itself is burned out.
The contacts have a layer of silver plated on them and are quite robust, but as mentioned before, the carbon builds up each time the contacts make due to the smallest arc.
It's worse when they open on dc inductive loads due to back emf. Mentioned it earlier but flyback diodes drastically reduce it and increase the lifespan of the relay. We used to change relays every year in a factory that had a lot of relays driving solenoids. You could see the huge blue arcs when they were opening off. I went through and put diodes on them all and almost completely stopped the arcing across the contacts.
Curious why you don't sell a station that can utilize hot tweezers?
The boss is happy that he saved hundreths of dollars thanks to his emplyee's skills
Got it working. Ultimate goal achieved/
Not a solid fact but for certain automotive applications 20K to 30K cycles is the expected life cycle of a relay comanding for example, a window regulator. Contacts erode.
LOL... Making up numbers.
Great video as always but today with a personal flare!
Alex, What watch are you wearing?
hand shake video would be fine,great one btw
