I love the fact you're so honest, open and transparent - and you both (big boss too) have a strong work ethic, but you can clearly have a laugh in the shop to. That's awesome!
The videos i watched ever without skipping anywhere is yours. Loved the way of your repair and have studied so much from you... You are a good teacher too..
Hi. I'm a german guy. I found you on youtube yesterday and I watched your vids for hours in the row. Great stuff, great work, great vids. Thanks for that. Maybe I have a hint for you. If you messure a cap inbetween a circuit, the meter can show a differ value than it should show. Often the shown value is higher then the real one. Remove the cap from the circuit before measure up. Then it is easier for you to find out the right spare spart. Best regards...
Thanks always for sharing. Thanks for comparison troubleshooting. You are happy. The customer is going to be happy. I am happy. Everyone is happy. Be blessed.
when i was watching louis rossmann i was always thinking "damn please speak slowly so i understand you" :) i was rewinding back 5 times to understand what he was telling about a board. now that i found you, i just say THANK GODDD
I just repaired mine 3 audio boards by finding that capacitors also effect on output... Those parts are working great now man ☺️ thanks for such informative video
I'm also always happy to see the repair videos that you do from start to finish really observing in detail. Thank you for educating us. Whether it's a successful project or a failed project it doesn't matter because experience is very expensive. Greetings from Indonesia🇮🇩. And I'm still loyal to be your subscriber. It's a great job !!😎👍
If you go one step further, you would find an application schematic in the PCM1808 pdf specification. This one shows 10 Ohm for a filter resistor in the +5.0V to pin 3. 4R7 will also be fine. It also shows a 4.5uF/10V in parallel with a smaller value capacitor for the VREF voltage coming out of pin 1. The pdf states "Recommended capacitors are 0.1-μF ceramic and 10-μF electrolytic" The same decoupling combination is also present for pin 3 (VCC) and pin 4 (VDD) to pin 5 (GND). User application schematics are often followed 1:1 by designers, so is a good starting point.
I just liked the way they work with joy and in peace there. Sure there are crazy days in workshop, however usually i dream of a job like that. Actually i find myself learn how to approach to faulty devices before attempting for fixing by often watching such videos. Thanks for the valuable experience u share.
The value of that cap is not important as long as it is not too low. It is a bypass cap for the ADC likely 10uF paired with another smaller likely 0.1uF cap. The speaker should be able to work without that cap. It just wouldn't meet manufacturer specifications. The cap probably measured 16uF because it was in circuit.
It's just awesome! What a wonderful knowledge and skill you have! I'm big fan of yours. It's quite surprising that you mend the things without much circuit diagram and other things. Hats of to your logical sense.
Alex I think it was the mode, those chips do the three things, FM radio, Bluetooh and AUX mode so, if last time was left in radio, you will get that sound like airplane, it keeps the last mode because of memory.
The PCM1808 device is a high-performance, low-cost, single-chip, stereo analog-to-digital converter with single-ended analog voltage input. The PCM1808 device uses a delta-sigma modulator with 64-times oversampling and includes a digital decimation filter and high-pass filter that removes the dc component of the input signal.
no need to replace that cap with 16uF, even datasheet recommend 10uF. As that common value probably even original is 10uF but measurement in circuit give you wrong reading.
pcm1808 is a stereo analog to digital converter with sound noise reduction , so its obvious that its responsible for the noise coming out of the bad board ,

I have an Altec Lansing speaker that has a buzz. It is a bigger unit than this but may be the adc. It would be nice to fix that speaker. But first I have to buy some tools and get some practice.
That was so cool. Say, what do you think caused the cap to blow in the first place? The chip failing maybe caused it? Big Boss dancing had me laughing.
I mean... this is what I would like to see as a serviceman. "Ey yo i have 2 not working boards, not sure if you worked on them before so sending you one that works so you know what is where"
I remember when Altec Lansing made the best speakers on the planet, now they are just crap. I'd toss this abomination and buy a JLB Extreme or equivalent.
From the start of the video i noticed the static noise is always the sound ic at fault and for the cap blown means the sound ic blown that for a reason
My Aftermarket car radio makes loud static when the volume is normal when I hit a bump. Then when I hit the radio it goes back to normal. I am double checking the Caps looking for anything that is not normal. Can you help please.
It's always nice to get a thorough note describing the issue, and getting spares as well is a bonus.
The good spare definitely helped. Customer did his homework and was ready to pay even if boards were not fixable to compensate for time spent.
Another great fix again and seeing big boss dancing is just a cherry on the cake 😊. Keep up the great work!
I love the fact you're so honest, open and transparent - and you both (big boss too) have a strong work ethic, but you can clearly have a laugh in the shop to. That's awesome!
Love the smile on your face every time you manage to fix something!
I love your smile of pride and satisfaction in those moments when you figure out how to fix stuff.
The videos i watched ever without skipping anywhere is yours. Loved the way of your repair and have studied so much from you... You are a good teacher too..
Big boss’s got the moves!
Love to see the "Big Boss Rock" It will be a new hit! Greetings from the Philippines.
You deserve far more recognition for the quality of your content.

Good work and Big boss is dancing because he is happy you fix that So Keep going the Excllent work
Very nice to witness how you get happy with a device gets fixed after all. See some peaple are just meant for this job. Carry on.

Good job like always....hope we see big Boss dancing one more time😂👍.
Greetings from algeria
I was shouting it's the chip, it's the chip ! Big Boss Boogie ! Thanks for the videos Andy M6APJ
Great video. Big Boss stole the show!
Strange to see him dancing.
I always thought big boss was a serious guy...lol.
It's always the quite ones!!
Same thinking here 😃
That was classic to see Big Boss with a happy smile and moving to the beat. Next the little girl dance with daddy!
You guys are the ultimate team!

I have a 15 years old Altec Lansing 2.1 powered speaker set-up still going strong.
That's the dance of money trickling into your pocket! Good repair and a big shout out to the big boss!

"If something blows it shows!" good one 😄👍
Makes sense that an AD converter would be causing the problem.. good job sir. I learn alot from this channel
I´m not really into this bussiness but I really enjoy your work. Sorry for my english.
Great dancer, very funny.
Good job.

Just happens upon this video. I will definitely be binge watching.
From PCM1802 datasheet, those are decoupling capacitors of 0.1uF and 10uF.
Your awsome,explainings like a proffecer.greeting from srilanka
Big Boss rules!! He is the man!!
Great Video keep it up...
Big Boss got some moves.... great video.
Alex I think it was the mode, those chips do the three things, FM radio, Bluetooh and AUX mode so, if last time was left in radio, you will get that sound like airplane, it keeps the last mode because of memory.
I love your work man.it is good to see big boss dance
no i am not binge watching ....wtw gr8 work big bro learning a lot from you
The like that i give is for the dance and happyness of Big Boss :)
👍

Big Boss👍🏻🙏🏻👌🏻 stay healthy live long.
2:16 dude you are listening to a Sea Shell.😍
Good job I love your speed and the way you think GREAT ,I am from India ,here I am doing DSLR camera repair centre ,
Big Boss with the moves. Look out now!
Awesome ✌️✌️✌️
Big boss's dance and fix
That was worth watching just to see big boss dancing 🤣🤣🤣
Awesome job as always
tripple like on this video because I see BIG BOSS rockin'
biss boss realy happy with your work
becoz unblievable work had fix
İ am not speak English but i enjoy your video nice work . Thanks big boss for dance
video of the year
Well normally I just like and comment but this one wish there was a must see button just for the dancing 🕺
One like for your video and another 👍 for big boss dance..
Good work ...thank you for the lesson......keep on.
You are the best of the best!
Sweet! Awesome work.

Ive learned so much in just a few min
Thank you
ما شاء الله انا متابعك من لبنان من وقت لي كنت تحكي انكلزي كنت افهم عليك كل كلمي
I enjoyed watching.

It pass midnight it funny to see big boss dancing ha ha
The "Chip Master"! 😁
@NorthridgeFix Curious if you were able to fix the other two boards with the parts you ordered. Is there a video?
How come 4.3 Ohm resistor measuring 7 Ohm in-circuit may be good? The total resistance may go lower, not higher. What I am missing?
I mean... this is what I would like to see as a serviceman. "Ey yo i have 2 not working boards, not sure if you worked on them before so sending you one that works so you know what is where"
lol it is nice to dance when something works. Everybody is happy.
Good work
VREF pin... must have blown out the connection from the digital side to the analog side... or just the ADC altogether.
Music can do amazing things.
I like your videos neet and clean ..love from india
Se quedó una resistencia de 4.7R sin cambiar...
Hi,I have a question. You can measure the capacitor in the circuit,you dont need to take it out?
I really enjoy .
Hi from morocco ..good job boss as always.where r u from i heard u speaking arabic !
Great job 👑
Aha hello from lebanon ! Nbassatet sm3tkoun 3am tehko
great job , im a big fan of you. someday i will geat taht weller station. and that flir camera. greetings
Big Boss dancing is legendary
I am new to the channel. I am assuming that big Boss is your Dad. Either way it was awesome to see him dance to Micheal.
Did it worth to fix it? Not sure how much does this cost, but maybe would cheaper to buy a new speaker :)
It doesn't matter, customer wants it fixed, we quote him, he agrees, we fix it.
I remember when Altec Lansing made the best speakers on the planet, now they are just crap. I'd toss this abomination and buy a JLB Extreme or equivalent.
Taught me how to fix speakers different noise
Haha so funny, good work. Appreciate you...
thanks . so many things to learn in this vid
hello . what temperature for the air gun you use on smd ?
From the start of the video i noticed the static noise is always the sound ic at fault and for the cap blown means the sound ic blown that for a reason
very awesome.. well done!
My Aftermarket car radio makes loud static when the volume is normal when I hit a bump. Then when I hit the radio it goes back to normal. I am double checking the Caps looking for anything that is not normal. Can you help please.
