AMAZON Echo Show 5 with FAULTY Touchscreen | Can I FIX it or is it HAMMER TIME?
HTML-код
- Опубликовано: 6 окт 2024
- This Echo 5 was very kindly sent over to me by David. It's got a faulty touchscreen so is stuck in set-up mode, and is basically a brick.
Let's crack it open and see if we can work out what's wrong!
Hope you enjoy!
Steve

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 👍
That short you were measuring was an inductor that is part of a tuned circuit for the antenna output.
Wow! That one tiny cap. You should get a medal for that fix. GG
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.
I'll just upvote this one too! Great job fixing that ribbon cable!
The music was a special banger in this video! Great work as always.
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.
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.
Congratulations on getting that working again!
Great job fixing that! The thermal camera really saved the day.
Gratz on the hard work. You know have the most advanced alarm clock in the world. At least that's what I used my Alexa for : Alexa program an alarm for tomorrow morning 6 AM.
@9:17 Now thats a proper car wreck! And WoW, this is some great work. Congrats!
THE SIZE OF THE CAPACITOR AT THE END IS NO JOKE
im having a case of deja vu
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 :)
You didn't replace the cap?! Come on Steve!! Don't make me get Dave involved!!
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
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
The Box Part 2, awesome!
19:33 I thought we were about to play darts for a second.
It's like a re run I am sure I just watched this two hours ago
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 sorted rail is the wifi / bt antenna.
TUUUUUUNE!! Love Martha and the Muffins Echo Beach :) Well done for that, isn't there just a smallest OCD part of you that says AHHHHHHHHH I have put a capacitor back in! :D
The mighty BlurCam™ is back!
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.
Steve's shirt must be imported. Ninjas aren't allowed in the UK.
The name Teenage Mutant Ninja Turtles has been used in the UK for several years now
@@PixelatedH2OYes, but that is a lot less funny than the Teenage Mutant Hero Turtles censorship and the jokes it creates.
Love your vids mate. Been binge watching them for couple of weeks. What microscope are you using at the moment. The clarity looks 👌
the only thing missing is the echo 5 playing sunny and cher i got you babe.
Love Gordon ❤️
What happen
Apologies if this is an obvious question but how or why do these things still work with a component removed? If the component isn’t needed, why is it there in the first place? Presumably it’s there for a reason? What I’m seeing is an expensive device that would have been junked if it hadn’t found its way onto Steve’s desk for the sake of a failed component that does absolutely nothing anyway.
usually those filter caps are for noise suppression. they improve reliability by blocking AC noise on DC circuits. sometimes they are also for FCC (in the states) compliance for avoiding unlawful EMF emissions on protected spectrums.
some capacitors in circuits are called decoupling capacitors, these capacitors aren't essential for the device to work and mostly are there to reduce noise in order to keep the voltage strictly within spec, chips and devices often have some random tolerance based on the purity of silicon, etc
let's imagine that a chip has a spec of functioning between 3.3v and 3.5v, a decoupling capacitor is placed to keep the voltage at 3.4v, otherwise the voltage would fluctuate between 3.2v and 3.6v
now, the silicon impurities could make the chip still work at even 3.7v without a hitch, but it could also make it malfunction if the silicon impurities make it so it can't work at 3.6v or more
the chips are made within a threshold, anything beyond that is not guaranteed to work but *can* work
IoT private data harvesting crap definitely not worth the hard work Steve puts into it... but I suppose it's a good fix-sercise. xD
Also, first time I saw anyone fixing fault on a ribbon cable, even if it was a simple faulty cap removal. That thing is smaller than a grain of sand.
Was reading some comments, my complete noob guess turned out to be kinda right. Part of the antenna for Wi-fi/Bluetooth the fact that everything on that line was shorted.
Seems that sometimes they have all sorts of weird wizardry into them to get them to tune to the right frequency and eliminate interference. The blue components, are they filters?
Anyways, good stuff!
Brilliant!
why does that echo sound like the belt on sound on airplanes? :P good video as always :D
182 day. Aw man. I could almost taste that pizza.
u need to get some hot tweezers for this small stuff. much easier to take off and put on
A half hour video? Looks like this one might fight back. let's see what happens.
Did you get copystruck?
Looks like Steve went back and blurred some of his personal info toward the end while he was doing his setup.
The Echo of the beach.. da ..da .. daaaa
Steve could the shorted area be for the Wi-Fi antenna?
It's always the flange capacitor
What was the personal information?
Good sir,how does one get in contact with you outside of RUclips.
Reflow
I need one of those microscopes but can't afford one 😢
can you not tune down the air speed on the heat gun. ?
When removing shields you can use a large solder iron and put a big solder blob in the middle and heat it up.
Why did you use hot air for that capacitor? Use a solder iron for God's sake ...
What is that 6 pin blue chip I need them?
29:36 Choon
I just don’t understand why anyone would skip the rhyming
Did you just quit fixing anything you bought yourself and just uploading things since to you?
why the reupload?
He forgot to censor personal infomation
"Amazon weren't particularly helpful," are words that should just be set in stone at this point. No, a $5 Amazon gift card is not going to make the situation better...
So true!
I'm not sure what an Amazon customer services bot can do about a faulty capacitor - no clever reset sequence is going to fix that.
ohio fish rescue sir
Nice
