Can I FIX a BARGAIN BOX of ARGOS RETURNS & Make MONEY $$££€€
HTML-код
- Опубликовано: 6 фев 2025
- Hi, I bought a bargain Argos Returns Box from eBay for £20 + £7 postage. This box is full of faulty items that have been returned. Can any of them be repaired and is it possible to make money from a box like this? Let's find out.

Remember that this is just for entertainment and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things. I do love fault finding and trying to fix broken things, so I hope that comes across in this 'Trying to FIX' series. Many thanks, Vince.
There are actually two kinds of laser potentiometers, signal potentiometers and power potentiometers. Power potentiometers are usually found either on a flex cable leading to the laser diode or on the same assembly/board as the laser itself. These are usually fairly hard to access. The other one is a signal potentiometer. These are usually somewhat larger screw potentiometers that are on the motherboard or controller board. The signal potentiometer is usually the one that is actually accessible in most devices. Optical media works by bouncing a laser off the disc and sensing it, the signal pot basically provides a way to control how much voltage coming from the photodiode is interpreted as a "flat" reflective area versus a non-reflective pit. Since it has nothing to do with power supply to the laser, it doesn't directly affect longevity.
Long videos are the best!
👍
I fully agree. Love the longer format videos.
Exactly .we want more !
For the people that can’t watch it in fulll length those people can watch it whenever they can in parts. Please keep making the longer videos.
I agree very nice 👍🏼
OMFG. Daniel O’Donnel. I’ve been away from home for 25 years Vince. I thought I’d escaped him. And you just brought him back 😭😭😭😭😭
I've still got my Bush transistor radio Type TR82B, I used it as a lad around 1963 to listen to Radio Caroline.
When I dug it out of the attic around 4 years ago it still played but had the ominous capacitor buzz.
A 20 minute re-cap and it works as new once more and it has it's own pride of place spot on a shelf in my workshop.
The Bush radio you fixed is a very cheap and poor copy of the TR82B, the original 1963 model which is stuffed full.
Yip no chips that control everything, it has proper transistors and a mass of wires.
Im from Ireland. Love your stuff. I was surprised when you pulled out 'wee Daniel', :)
Sorry to here about your mother
On MP3/CD portables, the lasers do go out of focus after years of use especially outdoors (autos) in winter/summer. Was hoping to see you recalibrate a laser. Usually has 2 glue-set adjustment screws, just like the read head of old tape decks. Takes a few minutes to figure out, find the extreme range of "working" on 2 axis, and then set dead center. Most factory fresh were not set very well, but with digital its pass/fail. Skipping, short battery life, and slow loading are common symptoms. A challenging and fun fix at least once. Well worth doing on any high-end vintage CD/DVD player.
The anti-skip features reads the disk slightly faster than the music plays. When it starts playing the anti-skip buffer will be at 0 seconds, as it plays it builds up until it's full (40 seconds or whatever the limit is). If it can't read the disk fast enough it runs out. Or at least that's how mine used to work. It had a display showing how much music was buffered in seconds.
The idea to inject audio into the circuit before the amplifier was great. I have no doubt that will come in handy for diagnosing my own repairs in future. Great idea, thank you Vince.
Thanks Philip, apparently you should be using a capacitor in circuit with it to stop DC voltage accidentally going in and damaging the bluetooth speaker. I wouldn't want you to blow your favourite speaker 👍👍
@@Mymatevince Ah where's the fun in playing it safe lol.
@@PhilipBryden 😂😂
@@Mymatevince I built a simple sine wave transistor oscillator to inject audio (capacitor on the output of course). No problem with copyright.
30:20 this made me nearly cry 😢
Your mum must of been a great person ❤
Vincenzo, if you purchase or build an audio probe, you can easily probe around the components without fear of surging voltage into your speaker. It can also be a rudimentary way of "hearing" if some signals are present.
I was thinking that. A 1kHz sine wave signal injector would also be handy.
I like the blue mat / sweater combo. My mate Vince got style! 😉 Absolutely love the long videos!! Impressive fault finding! Good job!
Just watching you struggle with the Multimeter probes trying to apply pressure and getting a reading at the same time, brings back memories. We all needed a third finger.
50:08 No need to edit it down. You're very good at thinking out loud for us while troubleshooting. It's interesting seeing your thought process. Sometimes the camera can be a bit of an issue as you tell us what your doing but are actually off camera or have it focused next to where your working. But you'll get better with that over time. Great vid. 👍
I've been a fan and a subscriber for ages and I just have to share this with you: instead of CA (superglue) in this situation get yourself some ABS cement and acetone. ABS and its derivatives will melt and once cured (allow 24 hours) will be just as strong as new! For loaded and/or thin parts I keep some scrap pieces of ABS dissolved in acetone - I pull a little of the resulting goop and reinforce (if configuration of the part allows) surrounding area. I lost count of household items that were saved from the bin this way!
Another great video. My grandad listened to Daniel O'donnell, that CD just brought some memories back 😂
7:48 would have been nice to see you use your oscilloscope here, I know not every man has one, but would have been interesting to see is all. I like your longer videos, it's like hanging out for a while with a friend. Keep em coming Vincie!
For the surface mount resistor with the 'end-cap' connector problem you may have just been able to solder it on upside down.
Electrolytic capacitors are the major culprits so well done Vince that was another fun one to watch
Watching Vince torture himself with parent-imposed music from his chidhood is priceless. I'm guessing that the person who owned the CD player with the broken plastic tab slammed it shut and broke it due to frustration with the crappy sound. The potentiometer trick is awesome! Well done, Vince.
I love the longer videos Vince. Thanks for the entertainment!
If you didn't get a content match, the Daniel O'Donnell CD could be the official MMV test CD. Of course, I am only kidding! Great video as usual. Cheers from northern Canada.
Capacitor came to my mind straight away, when the cd player failed only when under load. I agree the theory of dodgy capacitors might be more prone to popping when heated; sounds logical. Maybe something new learnt here.
Wow spotted the cap bridge straight away. But persistence and good testing methodology pays dividends in the end well done Vince. 😊👍
The Bush electronics brand is unknown in the US, but there is a popular 1990's alternative band from England called Bush that Americans are aware of. Thus whenever you do Bush repairs the song "Everything Zen" pops in my head. I think that you would benefit from heat-shielding aluminum tape ($1 from Ali Express), super fine tipped probes ($3), and a tone generator ($10). Hearing a 5000 Hz tone through a circuit is very satisfying. Continuing to enjoy the repairs, learning about England, and picking up tips along the way.
Love it over an hour. Keep em coming vince
Hi Vince, if you had a cheap oscilloscope you could check for crystal oscillations and frequency accuracy, plus follow audio circuitry paths easily. The chip you changed on the unit where the capacitor exploded, could possibly have had a bad solder joint so by changing it you solved that issue.
Shure, Everyone could Need some Osci`s. But, the aren´t Cheap to get. Would you send him One that he could made Propper Video´s?!? If i had one, i would Ship him, even if they is to repair. But i didn´t have One...Sry...
@@sniperla_666 That's the thing, today you CAN get a cheap scope, or even a scope kit! You don't need a high bandwidth scope for tracing audio or many things that Vince works on.
But owning one also means understanding how to use it !! There are plenty of cheap scopes on the market today under $100. Vince is in the UK I'm in the USA and shipping him one would cost more than the scope itself.
On the other hand there are plenty of manufactures out there, that could send him one for free !! Rigol, Keysight, Tektronics etc etc !! That would be worth the free advertising for them !! Vince also has sponsors, I don't, but I have bought all of my own tools and test equipment, because to fix some things its required !!
I just watched his latest Video, and I see he does own a small cheap scope anyway !! lol
Scopes are cheap. Rigol etc. are quite good for little money, or a simple used analog scope would be fine. He has a good soldering station, hot air, and even a FLIR. A scope would be a great addition.
@@SteveMasonCanada Agreed !!
I see he does have a little toy scope now.
I think he needs a real one !
Your patience is amazing.
Don't usually make comments, but from a consumer perspective I'd steer clear from bush products, great video Vince, really enjoy your videos
A 3D printing pen may be helpful in some of these fixes when rebuilding plastics. Some PETG or ASA filament and a little bit of practice. It also would help when you need to reinforce broken plastics. I love your videos! There hasn't been a single one I haven't learned something new.
ASP/ESP function works differently, the disc is being read at a higher speed and cached into a buffer, if there are to many read errors it just runs out of buffer and the disc starts to skip.
Normally Audio CDs are being read at 1x speed but with ASP/ESP enabled the disc spins faster and being read at 2x Speed.
Back in the days what i used to do with my discman is to swap out the disc on the fly and the track would change in the middle of the track, that was fun for a while.
You should not forget an Audio CD is still a digital Signal.
Love the long videos Vince, Great repairs, I have had caps blow like that it does wake you a bit lol
Keep up the good work, 😊
Cheers Gary. Hope you're keeping well👍
@@Mymatevince Hi Vince yes were all good here, hope you and your family are well too, you were lucky with that cap, could of caught you in the eye if the top went….. I really enjoyed the long video, the one with the motor IC I would said the motor it’s self was faulty, i admit I learn something new everyday, no one can say they know everything if they did they’d be lying 🤥
6:50 obviously there is a DC Offset Voltage on the output of the Tuner Chip. That's why you should always have a capacitor in series to your Test Device (Bluetooth Speaker) A MKP Capacitor of 1µF is doing the job.
Love your videos! I found you 1 month ago, I watched all your videos from from 2 years ago to now, great stuff, you even convinced me to do some fixes I bought the faulty quarto stereo line and it was awesome when I found the fault that dopamine man hahahha, I get now why are you fixing things even when they are not worth it, thank you! Keep the good work, can't wait for your next video
29:44 I was really expecting Rick Astley to come out there..
😂
It's always enjoyable watching the videos with a few big glasses filled with ice and lime cordial 👌
Hey Vince, just catching up on your videos. Good call on the RF chip on the radio. I thought you would have used your scope as you could have easily saw the audio waveform and if the crystal was oscillating. I was thinking to myself (when you were heating up that chip on the CD player) hmm... is he not worried about those capacitors... On CD players, head moves to the home position first, then the laser usually focuses (disc detection), then it spins it. Great Job as always 👍
Thanks Mick I just feel so out of my depth with the scope. I have used it before to check audio, but right now I hand on heart wouldn't know if I needed DC or AC to check audio from for example that faulty FM chip. I know it would be AC at the speakers so I would probably check for AC coming out of the chip, but I just don't know. Same for the crystal, I would check that on DC, but I don't actually know if that is correct. Bad I know!!!!
At 23:32 you dropped the chip yet left heat gun in the same place for 20 second trying to recover the chip. YOU popped the cap !!
Great use of a rework station to sort those crushed clips out! 😎
Always use capton tape when working with hot air in the vicinity of electrolytic capacitors ... I was expecting the blowout when seeing how close the capacitors were.
I was just catching up on the videos, and was thinking to myself, bit close to those caps with the hot air...
I use aluminium foil to reflect the heat.
@@manolisgledsodakis873 Also a good idea - basically everything that can withstand the heat and create an airgap should work.
@@manolisgledsodakis873 That is an additional benefit - but the airgap is the most important thing, since air is a poor heat conductor (same principal as in an aerogel).
Another great upload Vince. Well done, keep them coming mate absolutely brilliant. 👍👏🏴👍👏🏴
Wow, someone really liked their portable CD players! Great video, glad to see these being brought back to life, and yeah I'm not surprised about the potentiometer causing issues with skipping. The resistance values were so different on each unit - one at 1.155k, one at 1.3k, with the 1.3k unit being worse... Someone should have made sure to test all potentiometers at manufacture to align them to a decent value (I would go with 1k, because although 1.1k works, it's a bit close to the 1.155k of the non working one, and if you put too much power in, it will burn out, hence I would choose 1k).
Also - if you really needed to/wanted to, you can often get job lots of telescopic aerials for radios. I have a few spare telescopic aerials so would happily ship one to you if you needed it.
It's a shame out going tech doesn't leave the market at its highest, instead of poor quality, design and cheap products finishing the run. It's great to watch you work.
CD Player that spins then dies (19:00 to roughly 29:40)
I believe there are three ways a capacitor will fail:
1. The cathode and anode fuses together, either creating a dead short or a low resistance pathway (less than 1000 Ohms, but above the continuity threshold of the multimeter). OR
2. The cathode and/or anode degrades, changing its capacitance. OR
3. It explodes, making the capacitor (or what's left of it) either full open or dead short, depending on the exact sequence of failure.
Using heat near electrolytic capacitors is ALWAYS risky. If you have to utilize heat near capacitors, there are probably two ways to mitigate the risk:
1. Remove the capacitors beforehand. OR
2. Use something heat-resistant to shield the capacitors. Radiative heat is weaker than direct heat. That's why people use kapton tape to shield components; while the thin tape will definitely heat up quickly, this heat radiates very slowly to the components below (or behind, or above; doesn't matter which direction, kapton tape will protect it).
That said, however, if that capacitor did fail prior to popping, consider that a massive stroke of luck (for which the above suggestions would've thwarted).
Hi Vince, what are you planning to do with a dozen second hand CD players?
Remember a lot of those reviews on Argos might be bad reviews, so the sheer number of reviews isnt an indication of how good the items are or how popular they are.
Keep the videos coming, Vince. You've encouraged me to start fixing stuff.
You touched on the question of 'who would want one of these,' whilst introducing the portable cd players. That question was already in my mind, whilst you were repairing the radio beforehand, who would want a radio that is only AM/ FM mono compatible, in 2023, a total lack of utility, I'm not a fan of those retro styled items either, a cold bland, black or silver case but typically far more compact, is better I think. As for the portable CD player, I still have a Sony (cd) Walkman, (D-FJ401) with built-in AM and FM stereo radio, which with a portable Bluetooth sender via the line out, is still something I use to this day. I guess if that fails then I might want a new replacement?
Regarding the capacitor CD player: a lot of motors use a starter capacitor. I wasn't particularly aware of CD player motors using one but it doesn't surprise me. If it was electrically leaky, it could've been failing to build enough charge to properly dump out onto the motor to get it going.
Well, I think you should really buy some scope, even cheap portable one will help you with a lot of repairs, and help you skip some steps, for example checking if crystal oscillators oscillate. You could also connect one to audio output of any chips and look for audio signal. For bluetooth speakers you could connect them to your phone and use some apps to generate for example 1khz sine wave and look for it with scope.
Hi Vince love your videos. It's amazing how poorly built bush Goodman's and alba are now. I had a friend that worked for a company that repaired rejects of all 3 brands truck loads every week. He was a good repairman on electronics and have loads of spare parts from him . He still has 20 mini disc players from years ago. I gave him my NAD 3030 amplifier to fix as I blew a channel and I had no access to parts back then in 1996 sadly he couldnt be bothered got it back a few weeks ago but think its going to be a challenge now I tried to soften the blow and offered me the mini disc players I said no lol. Keep up the good work want to see the roller on the road too
If you are indeed turning the pot for laser power you should know we used laser meters for a reason not just measured value. Because of internal difference in the lasers what fit one might not fit its brother. At least that was how I was taught at school back in the day and how we did it at the repair shop.
I stopped buying Bush products 20 years ago and watching your videos it feels totally the correct decision..
😂
To be fair I've got a bush TV in my bedroom and visually I prefer the picture compared to my newer far more expensive Samsung TV.
Yeah, at the moment it seems like Bush is now being used as a cover brand for the cheaper ranges of products used at Argos. Other brands have done this as well - e.g. Goodmans is now used at B&M stores for their budget electronics, despite previously being a better brand.
@@TheSpotify95Goodman's has been dogshit for as far as I remember. A kid decided to snap my Sony discman and his mum replaced it with a Goodmans cd. Player what a pile of shit that was.
Yeah now bush is basically argos own brand, I believe only sold at argos. Like how currys has currys essentials.
The CD player might have been just a dodgy connection on one of the chip legs which you fixed by re-soldering.
yes saw it, there was a bridge
Nice video and nice fixes Vince! By the way I can't obviously speak for all CD players but the way the "Anti Shock" usually works is by reading the CD at faster than playback speed to fill the memory chip with audio data. And then as you said it plays it from the chip while occasionally spinning up the CD to fill the buffer back up.
Now if the laser is weak or faulty, it can never "read ahead" and has to play it as is from the laser. I not think that it even gets to storing it into the memory. Hence the skipping. Audio CDs actually have built in error correction, but I guess that is not helping when the laser is bad.
50:22 i think there is a bridge on the capacitor on the lower side of the chip where the dot is
53:00 nmd then :)
Wow, you are so patient
One of my only positives 👍
Bush is now a brand that is owned by Sainsbury's who owns Argos. A long way away from the days of being one of the most famous manufacturers of British radios. A number of retailers own the names of former named brands to upsell budget electronic goods. Goodmans and Blaupunkt at B&M for example are two that come to mind.
Goodmans went bust long ago
bush is way better than alba
Yup, e-waste for the masses!
Bush was always rubbish, but one step up from amstrad
You are completely wrong, Bush was a British firm established in the early 1930's, their products were excellent & continued to make decent products well in to the 1970's .
I still have my grandmothers Bush radio bought new in 1959 and it is still working fine today, it has never needed any repairs.
Unfortunately, like many British firms, they went bust due to cheap imports, the name was bought by Argos who slapped the name on cheap junk from China, hence why the name is now associated with low end tat.@@lumsdot
Fantastic fixes Vince!!!! Longer isn't a problem =D Dont wanna spoil anything again lol - the cap thing earlier, I think it was that! The resistance thing later (on those few units) - I think will be lasting tbh!
Hahaha, be very careful Chris you will feel the full wrath of fury if you give away the outcome!!! I'm looking forward to implementing the patented GadgetUK 'solder wick trick' to tin up future traces 👌
Superbe work!!! I am an old engineer and watch collector. Girard Perregaux fixed the frecuency in 32768 kHz in late 60s. Cheers Patagonia Argentina
Just had an email from Patreon with Vince offering ‘a bit of a long one’ - That’s a bit of NoContextMyMateVince if ever I saw some! 😂😂
Straight onto Instagram Kip😂
@my mate Vince. Makes sense it was the exploding capacitor as the motor wasn't getting enough voltage to spin the motor. With weight on it. So I doubt the capacitor was working properly.
Man i love every video! I just started repair videos ! Hope to get as good and entertaining as you!
What a nice collection of faulty items fixed! Thanks Vince!
It's a pleasure devtty 👍👍👍
Most of your fixes are typically common sense stuff...just bad chips etc. But that little potentiometer trick on the final cd players was pretty neat- (not that I'll ever fix a cd player at this point but i'm glad i hung in there till the end to see it - that was cool)
I guess that the popularity might be because many people have a big investment in CDs and most of their music collection is in that format. The sound quality is not bad and it was a successful format.
I knew someone who had a massive music collection (thousands) on 8-track tapes. He was always on the look out for more players.
Electrolytic caps can boil the electrolyte if overheated by a hot air soldering gun...they can overpressure and pop from the boiling electrolyte.
When the capacitors are damaged and heat up, they work again for a while, this usually happens with the Gamecube reading unit. Possibly by heating the capacitors the discman started working again.
Time to get a signal Injector/Tracer, or seeing you have an amplifier simply get some fine tipped probes that you can plug into
the output or input of the amplifier, just be mindful injecting signals before preamplification, the sound needs to be attenuated
to avoid damaging sensitive input transistors and or IC's..
What a nice full box.. I couldn't imagine that portable CD players are still so common.
Enjoyed that, the laser potentiometer was interesting
In my younger days never buy anything from Bush or Amstrad. Cheap as chips and will not last. But in your case not working from day one. Amazing it was the chip, no pun intended. I bought a Ferguson MW/ LW /VHF radio with AFC in 1969. Where is it now? Sitting in my kitchen and performing like a new one. It does take 4 C cells, long before AA were invented.
Vince, pull out the scope! That would have been a quick way to check audio and the crystal.
These videos are so entertaining!! Thank you for these uploads
Great video. You'd have to be disappointed when you saw about 50 portable CDs in the box. The antishock is a must on these things
The anti shock is only needed if you are going to shake the player about. If you are not doing that, turn it off.
I happen to stumble upon such a cheapo chinese portable cd player though I have a standalone cd player from Panasonic and portable cd player from Sony.
I open the chinese one and made a line out and spdif (coaxial) from the logic board. Then hooked up with a dac and the sound was amazing.
These cd players can be used as nice cd transport.
Great video Vince well done.
Such a great video, so informative... Thanks..😊
With the black cd players try changing the good one to 1199 or 1300 and see if it then becomes faulty. Then it might be a case of potentiometer set up from factory
Yessss, great idea 👍👍👍
Vince, You're such FUN! said to self, Uh Oh Aiming Hot Air Right at capacitor. ...YIKES, .. _soon_ ... *8{\* Well, .. I got somethings right. lol rip capacitor 59:28 Tweak Potentiometer: Nice to know and see how done.
1:06:00 Anti Skip - just another thing to go bad, (in chip) tho - Only get Skips if never had option? Tweak?
so _Lovely of your Mom_ to 'send' the tunes; : } hope your Dad enjoys them. *Thanks, Cheers!*
Nice collaboration with Daniel!
As a laser hobbyist, I can offer one piece of knowledge for you on laser lifespan and laser death\degradation: lasers have a finite lifespan, measured in hours, like other diode light sources, but a new laser can have it's lifespan greatly shortened, and even it's brightness output diminished by 50% or more by experiencing a laser diodes greatest enemy: excessive heat. So, if the owner of one of those CD walkmen had left the device on pause for an extended period of time, then the diode could have experienced heat based degradation and loss of power. This is simply a guess, and I don't profess to know anything about why those devices you bought had laser power faults. Individual laser diodes manufactured at a cheap cost can have radically different response to wear. I've bought dollar store laser pointers that were happy to recieve 9 volts (compared to the 4.5 volts they get from their included batteries) and other lasers from the same store trip died upon receiving 9 volts almost immediately.
Love your videos, and I especially enjoyed seeing you enjoy laser-based fixes. Lasers can be finicky things, but they are fun.
Thanks for sharing your knowledge on lasers ECKitty, maybe the pause scenario was the problem then as that would explain the last one that was clearly used. If it left the factory faulty then it wouldn't have showed signs of use 👍👍👍👍
When paused a question remains if the laser diode was on or off. That's worth checking.
But I think it's clear that these cheap players had cheap construction and setup. The factory probably just slapped the pickups in and never adjusted the eye pattern or anything. Most will work, they make the money back, the failures just end up in the bin.
Till Vince fixes them.
I think, with that bush radio, given it is just am/fm and not digital, it likely isn't worth replacing the radio chip on it for the price the radios would sell for second hand. You should be able to find a suitable antenna on sale somewhere. They are a pretty standard antenna, and just use a small screw to attach.
500 degrees is extremely hot for hot air rework, I would not have my air set that hot. It only needs to be hot enough to melt the solder, so around 350 is usually enough. But given the capacitors are likely 85 degree caps, the hot air on the cap will overheat them quickly. I'd say that it was mrore likely a dodgy solder joint rather than the capacitor being faulty. Likely a faulty joint on the feedback circuit for the chip.
Given all these products are made dirt cheap, even if they have a 10% failure rate, the companies are still making money. The failures of these devices are due to being absolutely dirt cheap components in them. That's why they are not worth selling second hand. With how cheap these are new, repairing them and selling them second hand without warranty really isn't worth the time you put into them. You'll make more from the video on here :) This is the thing with these sort of "repairs". Even if it costs you nothing, you might only get a fiver for the device second hand, and if you spend half hour fiddling, you are paying yourself that 5 for half hours work.
Really enjoyed last one of these
Fascinating to hear the low output laser CD players, noisy but really trying. I was gritting my teeth for those electrolytics, then it popped. Otherwise your a wizard with that hot air gun.That resistor maybe knocked off when factory assembling the case. Great video.
I do believe those CD players are sold globally, and they're sold under different names. I have one like those, and it's branded Coby, I got it back in 2011. I think the battery cover on mine's OK, but then again I haven't used it in ages and I think I knew to pull the battery door out before closing it.
Super glue then reinforce your joint with more superglue and bicarbonate of soda sprinkled over it , sets instantly like kevlar
32:15 I don't think it was manufacture issue? I mean there was a cd in it letting me believe it worked at 1 point? Or maybe it was left in there when someone tested it?
Not sure about the cap on top of the chip - hopefully the chip doesn't produce much heat, leading to the damaging of the cap?
Very nice work. But really, since you are using hot air, you might damage nearbry components. Today it wasn't to serious, but one day you might cause an irriversable damage. Its just a "have in mind" comment. Keep up the good work, its a pleasure to watch your videos!
Love your videos Vince. In the boombox, one of the components that were touching each other was marked E5, can you tell me what that is?
Good question Nick. To me it looks like a capacitor, but I don't know why it is marked up as 'E'. Other caps on the board are also marked up as 'E' but then others are marked up as 'C'. Very strange. Hopefully someone else will know the answer as I would have said 100% they are capacitors.
@@Mymatevince Agreed, I have one in a dead inverter which is marked EC and is a dead short. I have no idea what to replace it with.
For those radios if it's not worth replacing the radio chip but the amplifier chip works you can add a line input on it and use the radio as a portable amp for your phone or some other device.
i was thinking that as well-it wouldnt be hard to get a cheap bluetooth chip and add it in to make a pretty cool retro bt speaker
@@colestowing8695 Yeah at least use it for something. If that amp isn't strong enough then there are bluetooth amps out there that are. I'd even use the board from one of those $5 dollar store bluetooth speaker/radios and you have a radio again even if it's FM only and a bluetooth speaker and some even have an aux input jack.
Long time viewer, love your videos. Just short question what temp do you do normal solder at? Like soldering on a mosfet.
Personally I use high temps for hopefully a shorter amount of time. Normally on my hot air station I use 450 Celsius, or 500 Celsius on a thick board like a PS5 for example. On my soldering iron I use 450 Celsius with a medium sized tip. The bigger the tip the more heat you can get into the board. I just do what I think works for me, but many people would use lower temps and heat the chips/components for longer, which may be safer for the items getting soldered and lead to less cap popping 😂👍👍👍
Those 8002 chips are really common in all sorts of (cheap) chinese devices. I already remembered the whole pinout from just working with them an infinite of times. And i think that you can also remember the pinout when you see the label for a few more times. Its litteraly burned into my mind. 🙂. Also interesting chip that radio fm chip. Seems like its a whole microprocessor and some rf hardware, i expected a analog circuit or digital non mcu based circuit. Seems like they like to put a microcontroller into everything. I also once came around the same chip, which also seemed to be dead. This is a long text but its a long video so lets do it! :). I do like these longer videos! Also the capacitor that popped due to heat is normal, because the liquid and gasses inside cook and expand causing a small explosion although the "faulty" capacitor might have exploded quicker then the others because it was bad idk. I also had that happen many times, also scared the h3ll out of me!
220uf 10V is a common capacitor voltage for cd disc drive spindle motors so it's highly likely that was the issue, it certainly is on Sega Saturns and Panasonic 3DO's
I always look forward to another MMV video, love them! thanks Vince, love returns fixes.
Might be crap for resale/profit aspects, but for practicing troubleshooting and actual repairs, 20 pounds is a solid value for the experience!
41:30 I'm pretty sure I've seen that exact CD player branded as "Craig" in the US.
Repair hero Vince saves the day again! 😄
So funny just watched your vid and advert for a new Daniel Odonnel album is l being released . Love your vids especially the Rolls ones.
😂😂👍 Brilliant
@14:00 - FWIW - I don't think creators realize how terribly LOUD that crappy radio sounds over youtube. It punches through the speakers and stabs your eardrums. This is not a complaint, just a public service announcement.
About the cap exploding;
They're all likely to explode when hit with heat, but faulty ones definitely tend to pop sooner, and with more "spice".
Probably a contaminant in the electrolyte.
Thank you 👍👍
Yeh those caps dont like hot air xd
Faulty ones will pop with more spice when power is applied, not with just hot air. Faulty doesn't make them pop easier when just heated without power applied. The heat from the hotair gun expands the electrolyte, and given these would be 85 degree rated caps, and Vince has said he uses excessive heat at 500 degrees, well, the little 85 degree cap won't last long with that sort of heat applied.
@@MymatevinceBe very careful applying heat around unvented caps like that (no score mark on the top).
In my less experienced years I had one fly upwards off the board and hit me surprisingly hard, just next to my eye.
I now know to either shield the caps from the heat, or remove them first.
Even if they don't explode, you're damaging them with the heat. If you don't care whether the cap survives, wear eye protection.
Cripes there's not much inside those Bush retro styled radios. Sad to see this landfill being churned out today from what were respected companies. Rant over... always love watching your videos Vince. I keep meaning to ask, what do you do with all this stuff after you've fixed it (or not)? 😊
In those retro styled radios its a single chip microprocessor with onchip rf hardware, its pretty complex and even supports an eeprom for storing the radio settings and configurations. Also for the "what does he do with them?" I think he sells some. He said "make money" in the title of the video so i think he sells them somewhere, maybe fb marketplace or just ebay
The "respected companies" no longer exist. Each "badge" name is simply being used by a different company.
Hi Vince. Not sure if you will read this but I've found a dash cam at the back of my draw that's faulty and wondered if you would like to have a look at it in one of your videos? 🤔 it doesn't power on and when you have a charger connected a red light comes on and even after 5 hours on charge it still showing a red charging light and still doesn't turn on. If your interested and still have a PO box I can send it to let me know. Could be something for Ur tea time video fixes? 🤔 love watching your video btw
