Better Pack 555ESA Repair. $10 Component Fixed a $1500 Machine.

[@griparian]

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

[@craigescapeddetroit5198]

Bravo. Great Job.

[@laborielkain1748]

Love watching big boss disassemble and or reassemble. Great skill and patience. Fine troubleshooting and repair Alex. Absolutely great.💖👑

[@somethingelsehere8089]

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.

[@muttleydk]

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

[@ApocDevTeam]

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.

[@johnny4498]

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.

[@nnnnnn3647]

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.

[@RayanMADAO]

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

[@peeteraavisto2420]

I noticed 2 cracked solder joints on the board edge at 4:04. Maybe even resoldering relay pins have helped to cure the problem?

[@horvathattila377]

There were no crack on them, just a little fibre.

[@sdttnkara]

Yes, I noticed that too.

[@Ryan_DeWitt]

@@TheMystikal82 Yes, you can clearly see it is fiber as it moves when he touched it.

[@nobuckle40]

"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.

[@synony6]

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!

[@bobert4522]

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.

[@robertoruiz7069]

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.

[@matthewhaddon599]

As soon as I saw the relay, then that was a pretty good place to start as the machine was clicking...good job.

[@outfield1988]

I am in love with low melt solder

[@_DSch]

Its nice that the relay was available to buy, I had to repair my electric stove since one of the "temperature control" (clicks on and off every time the temperature is exceeded) relays burned after 10 years and that relay was not available at any distributor at all (which would be nice since I can get authentic parts really fast trough my university), not even local ebay. I was a bit lucky that there were new old stock ones from china but since I needed them fast I accidentaly brought NC instead of NO relays Not a big problem tough, the power gets turned on by another relay so I resorted to a quick hack with a mosfet in the signal line from the microcontroller (to invert it), works a treat :)

[@ruudb72]

Double Satisfaction!! 😀 It does not need to be every time a computer that you show, this is a nice one too.

[@boromoose]

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.

[@heelspurs]

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"

[@BasssemBenabdallah]

thank you for writing this this is what I was thinking of 😇 Alex is the best 💪

[@RFC3514]

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.

[@horvathattila377]

Good ole tape dispenser...I worked DOD logistics for over 20 years and went through a few of those machines...when they work they work and when they dont and your in the middle of packing and its a needs to go out the door item.. frustration would set in and then you have to grab a tape gun to finish the job...lol my co worker swore by the manual tape machines that didnt require electronics you just pulled a handle to desired length...that was a back up we kept around also..

[@TheMixer1]

Big Boss to the rescue he knows exactly where all the connectors go , better than factory reassembly AAA ++++

[@bismilgraphic]

you guys are life savers

[@tonymontana897]

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.

[@synony6]

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.

[@barneymerrill3188]

Now they'll start sending in tape dispensers for you to fix!👍🤠

[@ericb9511]

I use to fix those all the time... FYI use Dawn Dish washing liquid to clean the tank brushes use the PINK DAWN

[@laidman2007]

Enjoyed this!

[@davidmunro5577]

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?

[@peter_ry]

Great video as always but today with a personal flare!

[@duckindaddel]

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).

[@nigelwright7557]

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.

[@Zensaitv]

Don't dispose, reduce and reuse lol. glad it was an easy fix but a relay that small running for 5 years sure could poop itself, good thing it didn't take anything with it 😂. Nice fix and good to see your back in packing business.

[@robertpage2023]

In business, you have to keep the profits from going out the door in such matters as repair of equipment just like you did. I've repaired many home appliances just by first looking up anything showing how to diagnose and then possible troubleshooting. Before the internet, I would go to book stores looking for "how to fix" books. Reader's Digest came out with such a library back in the 80's with very detailed books with good photos on how to fix pretty much anything. From there I bought tools like multi-meters and specific hand tools needed for whatever I was working on. I leaned how to do preventive maintenance on many of my home appliances to keep them up and efficient. I had a washing machine for over 15 years and a dryer even longer. Once you take apart a washer, you see things like mildew buildup under the tub rim and dryers full of lint that could cause a fire. I'd usually do preventive maintenance once a year on these and then do things like oil motors on my microwave or the HVAC motors. Cleaning the AC coils inside and out keeping them efficient and the filters cleaned every few months. Even door hinges and handles need oiling. And before you have a plumbing back up, take the traps apart and clean them. Facet washers and o rings will last about a year so replace them also. Waiting till things get so bad that they don't work any more will end up costing you money, time and inconvenience. One thing that can turn disastrous is the hot water side inlet hose that has about a 2 or 3 year life span. It is always under pressure and when it breaks, and you're not home, well, you can imagine the grade of destruction. IN any new house I've ever owned I've kept a maintenance book on all the different appliance and things like hot water heater or HVAC systems along with the regular things like can opener and more. This way I know the age of the appliance and the maintenance schedule on it. It will tell me the reliability of certain brands of appliances etc so I know if I'm getting my money's worth. I see now that there are these home insurance services for such things but they only payoff when the appliance goes critical and there are loop holes that they use to either get out of it or cancel the services. You don't have to be an engineer to do these simple maintenance and repair tasks. The internet has put everything right there for you. Just make sure that you look at many repair videos so that you can see all the other people's ideas and techniques. There are some on the internet that are just idiots and will cause you more problems so check out as many as you can stand to see how many jive with the same successful technique. Approach any and all for the first time with caution and go slowly. Don't guess but use common sense and good instruction. IF you've never touched anything electrical then get basic with learning from the beginning. I can remember when electricity was such a mystery to me. Yeah, I've been shocked a few times but nothing bad. Electricity is to be respected and to keep cautions when dealing with it. I remember hooking up my first live power cable to a house weather-head but I was on a fiberglass ladder so basically I was not conductive or grounded. Stripping the live wire coating and sliding on the crimp-able sleeves And then using the big metal crimpers. It was scary but at the same time I knew as long as I touched nothing conductive or grounding that I was safe. IF you think electricians never get electrocuted, you would be wrong, It happens all the time.

[@christopherkelly8245]

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.

[@chrisgr00ver]

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.

[@SONNYemc]

Big boss enjoys the moment of truth 😂, حلو حلو حلو

[@johnr3435]

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 😀

[@ChrisHiblerPinball]

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.

[@olDirdey]

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.

[@wartlme]

I have had good luck fixing appliances like dehumidifiers and refrigerators. They way the board is designed, it feels like you are working on a device like that.

[@howzum]

I bet the customer was happy with this repair lol

[@RFC3514]

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.
