Those blue components (with a white dot) are inductors. They are nano Henry for RF and act like shorts to DC. The blue component with six pads was a balun. The tracks on the PCB in that area were laid out very straight with lots of ground vias near them. This is a sign of an RF track with controlled impedance. It didn't seem te be the case here, but many antennas are designed in an 'F' pattern where they are grounded. The ground seems pointless at DC and low frequency but controls the antenna at RF. It is better not to mess around with that. The capacitor you found shorted was on the flex directly attached to the touch panel which is likely separate from the display. The small connector carries power and digital signals to the controller chip on the flex and that creates the touch signals to the panel. I am glad you made your voyage of discovery because I had my head in my hands through much of this video hoping you wouldn't do what you did. However, we learn best from mistakes...
You say you're crap at this but you've got bloody good now Steve mate. Some of the things you've repaired in the last year are impressive, stop knocking yourself mate.
$0.00001? Likely only for bulk orders such as those for large-scale manufacturing like Amazon and never for individual orders for the casual DIY EE or home repair like Steve and others.
The line with the short looks like an antenna, and the 0805 package 6 lead chip a balun. It’s common to have a DC short to ground in the form of small inductors (no need for large values at high frequencies) as part of filtering and impedance matching the antenna.
Great work. It always amazes me that it just seems cheaper for the company to effectly throw these devices into e waste due to a dirt cheap component rather than fix. You have been an inspiration Steve, i now have a go to see if i can fix or at least understand when i have broken electronics at home.
Your patience in dealing with those small components and glue are amazing! I would have chunked the thing in the bin long before you got it fixed. Great video as always.
Hello Steve, nice to see your still fixing things melting plastic is sometimes unavoidable, keep up the good work. I find your channel relaxing and satisfying.
So funny when I saw all the components moved under the can. Say what you like about us brits, but no-one does non-plussed dry humour and sarcasm like us. Super-enjoying your videos. Brilliant work 👍
Hi steve. Great fix. It looks like the bluetooth / wifi chip has an antenna connected via those blue devices. You need to remember that DC and AC act differently. What appears to be a short to DC might be a tuned circuit and not a short to a particular AC frequency. Tuned circuits are often connected to ground. So maybe the blue components were coils forming tuned circuits. It looked like if you follow where that track goes it ends up at the copper pcb antenna for bluetooth/wifi. Dont always think DC !! Coils can be shorts to DC but have impedance to AC. Study AC theory a little, and it will start to make more sense.
Well done. Probably too late now, but that cap (pin12 of the IC) was probably 2u2 and as that is one of the power rails (AVDD28), it's probably worth fitting.
Dude, you really made that Echo Show 5 come back to life! 🔧 It’s kinda wild how something so small can mess everything up. 😂 I love watching you tackle these repairs, it makes me wanna fix my broken stuff too! Just hope I don't mess it up like you joked about! Keep it up! ✌️
Great job! Thanks for showing the component. It's easy to forget how tiny everything is when you're looking at it on a screen. You should zoom out every once in a while to remind people what you're working on is so tiny!
At 12:05 a capacitor in the top left for the sense line of that sub powersupply got disconnected, you can see that the top of it is not connected anymore. Would be good to put back but it seems works without. Great video!
Tip: use aluminium or copper tape to stop melting the plastic or the screen use enough to spread the heat., don't forget to unplug or de-battery first. Make more use of the thermal camera.
Great vid! I think these echo show 5 are infamous for their bad screen quality. The most notable problem it the flickering glitch/problem. both of mine have it, but I wont bother to fix them given the price of a new screen vs a new unit
Loving the Humour, similar to mine. I have been watching for a while now. Keep up the good work. Would love to have a channel like yours. Awesome stuff :)
Hindsight is always 20:20 but bringing out the thermal camera at an earlier stage would have helped. I saw brown discoloration near that cap straight away and the other clue was the neighbouring cap had desoldered itself meaning that bit was probably very hot. You could have used the thermal camera a second time and that cap would have been very hot! Those curvy lone or trace pairs are usually related to wireless (antenna) or transmission lines (High speed data). The blue inductors show it to be antenna related! Great Video!
Love the channel , such a curiosity each time a new vid pops up , amazing what you do and love your format and clever videography!! I’m not a budding electronics tech by any stretch but I’m trying to source a relay to fix my tumble dryer but can’t find a wholesaler with relevant part, is there a particular supplier who you source your components from or one that you can recommend? Thanks in advance 👍
From the "For anyone who's interested" department . . . the AD407 microscope you use in your videos normally goes for 260 quid-ish . . but there's a bloke on eBay who sells them for less than 50 quid (!!!!), all boxed, new and all that good stuff, I got one for 33 quid, I was 100% sure I'd get an empty box with a brick in it, lol, but there it was my very own AD407 ! Amazing quality, love the screen, spent the first hour looking at random crap : ) I then quickly bought a second as a backup, 46 quid for the second one . . . his prices seem randomly set and can go as high as 79 and as low as 45 (my 33 quid one was a 'make an offer' deal) . . . either way, it's a decent deal for people who don't want to shell out 260.
Appreciate your video's. Gave me the motivation to fix the ECU on my Laserjet 1300. Something was shorting out the 24V DC power when closing the toner door. Eventually found a faulty zener diode... GET IN THERE. Stupid zener.
Can I recommend a vacuum sucking pen. They make some manual ones and then some automatic ones. They're actually not that expensive. I got a 50 or $60 one off of amazon. It's pretty freaking awesome. You won't knock off components because you will lift the metal Lids right off. Remember straight up LOL. Excellent video as usual dude
I am sure you know that when checking for shorts via the sound setting, using your mul-timeter, if the part has a low resistance, it will make the meter sound. So a lot of your "shorted" soundings could just be low resistance readings. As for your password, I'm guessing it is "stupid"...tell me I'm wrong... lol The temp reading was well over the boiling point of water being 141+ C reading. Equally amazing is how you always seem to stumble on the bad part(s). That is a gift! Thumbs Up!
It's surprising how many of these issues are caused by shorted capacitors. I believe the little blue ones, part of the antenna, are inductors, that would explain why they measure as a short.
An alternative to using a heat gun would be those rice bags used for heat therapy. They come in an assortment of sizes and you heat them in the microwave.
Prob 1 of your best for a while, Steve is really enjoyable to watch, and the size off that cap ..I would love to know how they are designed and made.....keep up the good work ..... PS I have just ordered a cheap tumu scope. I also have a hot air gun soldering irons meters with continuity mode ....probably never get to use them like you but I have several dead laptops, so I may have a go
i think an important thing to learn here is that tiny spec of a component made this device a paperweight, touch is great but if it's gone the device is gone

Had to reupload this one, sorry if you've already seen it! Stupid visible sensitive information.
Names do that, I wondered already. In any case, still admiring your patience on soldering those tiny tiny parts back. I couldn't. Never.
I guess I won't do all that yelling at you through the screen this time.... lol
So glad it turned out well.... :) or did it?
Understandable. Good video either way.
@@Nobe_Oddy Feel free to yell at me again, I definitely deserve it on this one! 😂
Last name wuzzit? I thought it was strange seeing it the first time. Good choice to reupload 👍

We got PCB mcgee over here
Ohhhh so that's what those little blue components are. nH inductors. They are always in every single Samsung device I've opened.
you're taking the fun out of it 🤣
In other words the whole trace is just RF voodoo.
It was a fun journey for us mere mortals 👍
You say you're crap at this but you've got bloody good now Steve mate. Some of the things you've repaired in the last year are impressive, stop knocking yourself mate.
Wow! That one tiny cap. You should get a medal for that fix. GG
yes that is the worlds smallest cap, or at least one of the worlds smallest cap. 😲
Great job! I will never stop being amazed at how a $0.00001 component can render a $60 piece of kit useless
$0.00001? Likely only for bulk orders such as those for large-scale manufacturing like Amazon and never for individual orders for the casual DIY EE or home repair like Steve and others.
That short you were measuring was an inductor that is part of a tuned circuit for the antenna output.
Sure sure ...I'm still rubbing these two sticks together and still no fire,😅
I've been a huge fan of your channel for about 2 years now, but when I saw Orbital's the Box on Spotify, you just became my best friend.
I knew it was small but when you showed it on your finger I was shocked still.
The line with the short looks like an antenna, and the 0805 package 6 lead chip a balun. It’s common to have a DC short to ground in the form of small inductors (no need for large values at high frequencies) as part of filtering and impedance matching the antenna.
Don’t know anything about electronics but I found this fascinating,your patience and knowledge is amazing.
I'll just upvote this one too! Great job fixing that ribbon cable!
What a result!
Makes you wonder how many things have been tossed that could've lived on with 1 little component swapped 😭
Great work. It always amazes me that it just seems cheaper for the company to effectly throw these devices into e waste due to a dirt cheap component rather than fix. You have been an inspiration Steve, i now have a go to see if i can fix or at least understand when i have broken electronics at home.

The music was a special banger in this video! Great work as always.
THE SIZE OF THE CAPACITOR AT THE END IS NO JOKE
Just AMAZING! You're very passionate, calm and very patient. That pays off !

Was very satisfying watching you fix this after melting the plastic and ripping up those little bits.
Congratulations on getting that working again!
Well done. Probably too late now, but that cap (pin12 of the IC) was probably 2u2 and as that is one of the power rails (AVDD28), it's probably worth fitting.
You have soo much patience. I’d have launch that at a wall trying to get the shield dwellers back in place
Great job fixing that! The thermal camera really saved the day.
Well done!
First thing to check in anything that connects with cables is the cables and their terminations
Echo Beach, how utterly perfect for this video. Shakey Stevey or not, melted plastic record ended or not, you did good work here. Grats on the save!

LOL - Hurricane Steve's reflow work around 12min - priceless!
The Box by Orbital is an awesome tune. Top marks there Steve 👌🏻

I feel like the shorted rail on the Wi-Fi chip could be related to the antenna. But that's just my hunch. I'm no expert
VEEEERY nice one Steve! I really was hoping to see "the" counter not needing to be reset... But the repair in the flex pcb was great!
Nice Orbital reference.
when i'm watching your videos, it's funny that i get excited and celebrate together when you find and fix the problem
Patience beyond on this one! Great job
Wow. I did NOT think you were going to get that going. That's one for the thermal cam:)
Thats the most impressive fix I've seen you do yet
Tip: use aluminium or copper tape to stop melting the plastic or the screen use enough to spread the heat., don't forget to unplug or de-battery first. Make more use of the thermal camera.
The mighty BlurCam™ is back!
Great vid! I think these echo show 5 are infamous for their bad screen quality. The most notable problem it the flickering glitch/problem. both of mine have it, but I wont bother to fix them given the price of a new screen vs a new unit
The Box Part 2, awesome!
Loving the Humour, similar to mine. I have been watching for a while now. Keep up the good work. Would love to have a channel like yours. Awesome stuff :)
Incredible work! That thing is miniscule.
classic Steve.... good fix on the unfixable
@9:17 Now thats a proper car wreck! And WoW, this is some great work. Congrats!
Love the forwarding effect.

Cracking videos, good to see a local lad on the tube
You sir, are a troubleshooting king! Great work on this one.
Great work. Half way through I thought this is a no fix.
Hi. I was thinking why we never see you use a milliohm meter when checking for shorted caps. Thanks for your videos :)
Great repair, that was some patience needed there!
Appreciate your video's. Gave me the motivation to fix the ECU on my Laserjet 1300.
Something was shorting out the 24V DC power when closing the toner door.
Eventually found a faulty zener diode... GET IN THERE.
Stupid zener.
You're knowledge is growing - & that capacitor is ridiculously small! I have one of these Echoes & hope nothing like that goes wrong with it... :)
Episode 237 of Steve still using the air setting too high and having things fly away 😂 you're an egg Steve love your work!
You have the patience of a saint, wow
Amazing and difficult repair, great job!
No worries, so good i will watch it twice!
Hi steve love your repair videos steve what do you call that blue thing you put your screws on 😅
Speaking on behalf of all channel subscribers - we saw that title coming from miles away... About time too! :)
Fantastic. Really well done, you're getting good at this stuff, keep it up. Cheers 🍺
oh Steve you are so hard on yourself. As always great vid mate.
I was not expecting that cap to be so small, holy wowzers
Well done mate, what a fix ❤
Great fix Steve!!
Did you try the Bluetooth connection in the end?
Love your show Steve!
Dan from southern California
One of the best yet and that’s saying something 👌👍

Love your vids mate. Been binge watching them for couple of weeks. What microscope are you using at the moment. The clarity looks 👌
I am sure you know that when checking for shorts via the sound setting, using your mul-timeter, if the part has a low resistance, it will make the meter sound.

Keep the videos coming.I love your show
Looks like a tornado went through the board 😂. Tickled me that bit
Astonishing patience! What an incredible fix 🙏👍
great job who said these things are not fixable i hate the throw away society
“Or is it?” cracks me up every time 😂
"I have to take everything off to find out" - well, you are quite good at that... :)
Great video, glad you pressed on.
It's surprising how many of these issues are caused by shorted capacitors. I believe the little blue ones, part of the antenna, are inductors, that would explain why they measure as a short.
👍🏻 for Orbital.
You didn't replace the cap?! Come on Steve!! Don't make me get Dave involved!!
I didn't see Steve changing it!
The Box - Orbital 😍
An alternative to using a heat gun would be those rice bags used for heat therapy. They come in an assortment of sizes and you heat them in the microwave.
Prob 1 of your best for a while, Steve is really enjoyable to watch, and the size off that cap ..I would love to know how they are designed and made.....keep up the good work .....
PS I have just ordered a cheap tumu scope. I also have a hot air gun soldering irons meters with continuity mode ....probably never get to use them like you but I have several dead laptops, so I may have a go
i thing that's is the antenna where you have the shorts and the things are filter and other stuff to keep it on the freq it need
the Box, nice choice!
I took an old set of probes and soldered sewing needles to the tips, because the pointed probes weren't sharp enough.
The shorted track near the Wifi chip may have been an on board antenna loop ? going back to the wifi chip.
Great fix, well done
To find which one of many components are shorting, use voltage injection and watch with a thermal cam what gets hot.
wow that was more painful than usual. especially searching for a short circuit in the antenna path
I think those blue things are Murata 0201 chip inductors.
Excellent work.
i think an important thing to learn here is that tiny spec of a component made this device a paperweight, touch is great but if it's gone the device is gone
Don't skip the intro on this one guys! Nice beat. 🎶🔨
