Great job, also very nice of you to donate the monitor to a good cause. This world needs a lot more people like you.
Cheers 👍🙂
A customer brought an old Toshiba TV in to the repair cafe I volunteer at. It was a complete no power (no red LED) so I suspected a diode. It was indeed a diode! It's really rewarding to take "junk" and breathe potentially another 10 years of life in to it. The amount of carbon embedded in these devices we throw away and replace so readily is massive.
Totally agree, and well done at fixing the TV and helping the cause at your repair cafe!
Anther repair cafe technician. We are slowly starting to gather around this channel :)
Our dogs, Halgrimur and Bella would love to give a thumbs up, but as we all know...no thumbs, so they send their barks of approval and thank you for supporting the local dog rescue. Bella was a rescue from Romania. Excellent video and very clever diagnosis and repair. Greetings and best wishes from unusually cold Germany (6 °C in the evening).
Thank you 👍Say hi to the dogs from me 🙂It's been quite cold here the last few days. I've had to put the fire on 🙂
As an old dog i appreciate your kind donation to the local dog rescue center! WOOF!! 🐕
😂😂😂Cheers 👍
This one really was saved from the dump and put to good use. That was so nice of you to donate it to the charity dog centre. Enjoyed this one thank you.
Cheers mate 👍Glad you enjoyed it 🙂
Excellent work Mick. Fixing electrical stuff, I like, I like a lot, but fixing electrical stuff to donate to a dog recue centre, I 110% love with that.
Cheers mate 👍Yes she was going to buy one and I had this one on my bench, so I thought it would be perfect!
Your a star, Mick. A dumpster dive that benefits a charity. Your the best mate. Hope it didn't cost you too much, thanks for sharing with us.
Cheers Brian 👍I think it was around £5 for the TX, and I already had the caps on some old boards. I know the lady that runs the dog rescue quite well, I've helped out there before putting some LED lights up for here in the barn.
Very cool to see you repurposing that unit and donating it for a good cause! Can’t begin to understand all the things you’re doing with these boards but really enjoy your channel. Thanks!
Thanks 👍
Usually, the bulged caps are rated barely over their application voltage. Using a cap with a higher voltage rating will avoid future problems. One problem with doing that is they are usually larger, physically and there might not be room on the circuit board. Good repair video!!!
Sometimes the capacitors dry out due to the heat inside power supplies too and over time most fail eventually - I repair a lot of mixing desk power supplies which some people leave powered up 24/7
Thanks and very true 👍
I find the problem is usually they're just cheap garbage, they just manage to outlast the warranty. Other than that, as the other dude said heat kills them.
Great fix, great cause. For those playing along at home: Consider that this is a Vestel produced TV and that for those, you can often find complete circuit boards for little money on websites like eBay. Obviously, this repair makes way better content for TH-cam, but it might be easier and even sometimes cheaper to just buy a whole circuit board.
Thanks 👍Yes sometimes it's a lot quicker (and possibly cheaper) to replace a board, but where's the fun in that 😂😂😂😂
Capacitors🤨 and this time also a dedicated lighting transformer which was the good catch. Super job diagnosing and repair also nice of you to donate for a worthy cause. AliEx comes through again... Great video, well done, thanks. Stay safe.
Cheers Terry 👍
really satisfying to get a TV or monitor with bad caps, you can get involved (and usually not too complicated) remove some faulty components and fit new ones, and get a working unit out at the end, ok there was a bit more to this one but always a good feeling when it works out...
Yes, great when it all works out 🙂👍
Great job mate. The lesson is never assume that the new part ordered is good...😊😊
Cheers mate 👍Yes, funny as I had the same problem with the last video and dodgy parts too!
This had a nice ending. Never seen anyone test and replace the transformer. Learned something new. Thanks.
Thanks, yes I've never replaced one before either. I learned something new too!
This is a fantastic lesson for techs who use 2nd hand parts, which is a pretty common practice for repair shops. Something that only a experienced hand knows. Faults are often the same due to a design choice. That means the parts you use second hand might also have the same fault. Takes confidence and age to know your testing correctly and your new part might also be faulty not just your process. 😅
Thanks 👍🙂
Nice fault finding as always Mick. Great work!
Cheers Vince! I need to catch up on your latest one 👍
Excellent repair. So good that you found the actual schematics for it. We don't get that ever working on many things these days. So good of you to donate it also. Triple good! Saving from landfill, sharing how to, and donating to good cause! 👍
Cheers mate 👍🙂
Very kind gesture, hope the electronic gods will shine for the next one very good job, you make clearing pcb holes look so easy. Thanks for sharing.
Cheers 👍Hopefully they will 😂😂
Nice fix and a worthy cause to donate it to 👍👍👍
Cheers John 👍
Well done Mick you are a local hero 😀
😂😂😂Cheers Mike 👍
Well done ! Helping animals is a noble cause . You’re a good person with a good heart , thank you for all that you do!
Thanks so much 👍🙂
Another outstanding repair and a very decent, kind act, you are a good chap.
Thank you kindly sir 👍
Loved this fix as usual.
If one thinks about how many flatscreen TVs are in landfills, it doesn’t bear thinking about
I’d like to see you repair enough of them to mount them on the side of your barn and feed a camera from the other side into them, so your barn becomes invisible 😅
Thanks 😂😂😂Invisible barn.. Love it!
Kindness strikes again!
100% 👍👍🙂
That's amazing..... I never knew dogs would watch television.
I think it's the terriers, they are really smart.
Great fix and even better cause for the telly.
😂😂😂Cheers mate 👍
Nice job, and a good Samaritan as well. Keep up the great videos. Paul, USA
Cheers Paul 👍
Nice save & a great new home for the tv.
Thank you 👍
Great fix and generously donated. Keep up the great streams.
Cheers 👍🙂
That's a great place for it...... Cheers to you for doing that .....
@@cajuncoinhunter Thanks Cajun 👍
A great act of charitable recycling. Good job man. :)
Cheers 👍
Brilliant, and a hearty conclusion!
Thank you 👍
Cutting the power lead used to be standard practice when getting rid of electrical products.
Not sure why. I think it was in case someone took it and tried to plug it in and got hurt.
Our family always did it and we still do.
Its pretty common. I worked for 2 weeks at a local thrift shop and we always used to cut cords of devices that did not work and got sent to the recycle bin, and the reason was so no one would attempt to plug in the devices to be either met with dissapointment or a fire or explosion
Serious diagnosis. Well done.
Thank you 👍
Great fix once again. I thought that it was going to be a 10 minuter. Had to make another cuppa.😊
😂😂😂Cheers 👍
Those Cold cathode driver circuits are interesting. High frequency. High voltage energy can do some weird stuff. In general, it wouldn't hurt to inspect where the windings of any transformer solder to the pins that connect it to a given circuit board. I recently repaired a transformer where the solder connection had failed. That was a first but very rewarding.
I did have a look at the old transformer but couldn't see anything obvious. I did think it may have failed where it solders to the pin or something too.
great re purpose of what was destined for landfill . good on you!
Thanks 👍
Never seen a transformer/coil behave like that. They usually go short or completely open. This might be a bad connection where the wires bond to legs. A not-so-easy fault to detect, amazing work!
Thanks 👍Yes me too, I did have a slight poke at it under the microscope as I thought it could have failed where it joins to a leg too, but I couldn't see anything. I think I made it worse which is why it measured OC later on 😂😂😂
Stories of Recycling Centers, seems never just simple 'drop off'. Waste relieved, when products still have reuse in some form, Succeeds by Eyes spotting possible challenge.
Good Trip, *NICE Work! Bonus* making Dogs, or those carrying for them *Happy.*
Cheers 👍🙂
I managed to activate the cold cathode short circuit protection with my thumb a few years ago. Made a small puff of smoke, and burned a nice little hole in my thumb. Was an experience painful enough to remind me never to do that again!
😂😂😂Yes they can give a bit of a nip!
You are awesome, sir Mick! ❤😊
Thank you 👍🙂
Great, as always. And thank you for the on screen comments regarding the component values again 👍
Thanks and no problem 👍
Very nice job well done you know your TV 's im sure the dogs will love it to helping them
Thanks 👍
Well done also nice of you to donate for a worthy cause👏
Cheers 👍
That's a good return on your labor. I try to do as much as I can for anyone in need, too. I don't order on aliExpress anymore. I got ripped off too many times already and only got refunded once.
Thanks 👍Sorry to hear about your experience on Ali.
very good,you really are exceptional compared to others ,you know what you are doing.
Thank you 👍
You're amazing on so many levels...
Thanks 🙂👍
Good Job ! Great you donated it to a good cause
Thanks 👍🙂
I really appreciate you not only giving the TV to a great cause, but also for keeping it from just being e-waste! Great job! 👍🏽 and of course and as always well worth a thumbs up!
Thanks 🙂👍
Well there's a blast from the past, a SCART connector.
Yes 😂😂I remember when they just used to have an antenna connector and nothing else 😂😂😂😂
Nice repair and very good use for the tv 👍 Well done!
Thanks! 👍
Great video as always! Happy to read you get refund faulty transformer.
Thanks 👍Yes I was waiting for the other one to arrive so I could send pictures to show it was faulty.
Well done Sir. My wife always insists on coming with me to the recycle center now to stop me bring home more TV’s to fix. Its an addiction, I can’t help it….😂
😂😂😂😂Cheers Darren 👍
Cant beat a skip find :) Nice fix..
😂😂Yes 🙂Thanks 👍
Great work, as always, Mick! I have seen and heard a lot of negative comments about Ali, but I have had great results with the many items I have purchased from that website for many years!
Cheers mate 👍and thanks for sharing 🙂
brilliant job that worked out well
Yes indeed! 👍
What a great fix and great purpose for the device!
Cheers 👍 and I didn't even have to use my USB TTL converter on devttyUSB0 😂👍
@@BuyitFixit hahah 🤣
Well done. Lucky to find a dump (sorry, household recycling centre) that let you take a TV. At mine you would have to climb into or fall into a skip, probably an offence, if you survived. Allen Fleckney is another who advocates repair.
I took a 24 port gigabit network switch out of a skip a few years ago. It's still in daily use. Nothing at all wrong with it.
Cheers Ralph. This one is unmanned, it's literally 15 large commercial bins in a car park for cans, cardboard, plastic, and bottles. There isn't really even a place for electronic items. Someone just left it next to one of the bins.
@@BuyitFixit I remember those days. Sadly, ours is manned with automatic barriers, booked timeslots and guards. You drive up into a 20-car space and then drop all goods into skips, a fall of between 2 and 5 metres. Anything that was salvageable / repairable before, certainly isn't after. So sad.
I'm in the process of trying to restore an old ATX computer power supply, and the 4 domed capacitors I pulled out registered as "Damaged or Unknown Parts." Can't wait until the new caps come in so I can see if it works!
Hopefully it does🤞. I'd perhaps check the other capacitors on the board even if they aren't domed as they could still be faulty due to age / heat like some of the others were a bit down in this case.
Greetings from Italy. Nice work. I really appreciate you volunteering your time and expertise for a good cause.
Grazie👍
very kind of you
Thanks 👍
Sound job Mick you are a pro 👍🏼👍🏼
Cheers mate 👍
Well done! I'm sure the donation will be appreciated!
Much appreciated!
A lot of broken tvs I fix have blown mosfets also.
I've not came across too many with blown mosfets, mostly capacitors or cracked screens 😂😂
Good on ya! It’s always heart warming to do something for someone else and to see things given to a good cause 👍🏽👏🏻
Thanks 👍Yes deffo, I've done stuff like this for as long as I remember. I've always tried to help people. It was like when the guy from Australia asked me if I could take the chip out of my tractor and email him a copy of the file (video is on my channel if you haven't seen it)
Thank you for a great video. Please keep them coming.
Thanks, will do!
Great repair. Thank you for helping those who help others! Woof woof...
Cheers 👍Seems I'm barking up the right tree, or barking mad 😂😂😂😂
Another successful conclusion to an excellent troubleshoot, as well as taking another's loss and making it useful for a good cause! Thank you for sharing this video. Now, I have a Sony LCD TV about that same size with similar symptoms and your lesson here has given me a renewed desire to have a second go at it.
Thanks 👍Well hopefully you got a few pointers from this video. If you get stuck you could always drop me an email with some pics of the PCB 🙂
I really enjoy TV/Audio type repair vids like this one, I like to tinker myself but have very limited knowledge. This video was interesting as it touched on the problems I've had with the last few TV's.
I have tried to bypass the protection circuit on a samsung TV but I think I killed the chip as I read the pinouts incorectly still you live and learn.
I once also bypassed the olp line on also a device that had a 494 and i burned out the transformer and my room smelled like burned electronics and burned lacker for a few days... Bummer! But i got a new transformer and luckily it was not ome that was salvaged from old crap but rather from the official chinese manufacturer who made the transformer
Cheers 👍 Yes, but the main thing is that you learn something. Even a failed repair is good if you learn something, and everyone makes mistakes (as I did in the previous video when I caused the mosfet to smoke 😂😂😂)
Well done lovely video thanks.
Cheers Christopher 👍🙂
A friend was trying to fix a VCR. He suspected a 1000µF/35v capacitor but it measured 1020µF. He was about to solder it back in but I suggested he measure the ESR. It was ten Ohms! Replacing this cap fixed the fault. So NEVER rely on capacitance measurement of an electrolytic capacitor. Always check ESR first. This can usually be done in-circuit.
My tester usually shows the ESR unless it's 0 then it doesn't seem to display it. I was reading on the EEVBLOG forum that you can still have a bad caps that shows a good ESR too.
Good work mate you stick with it and see it to an end... and nice story to finish with! Lovely area you live in, to must do a little vid showing us the village and surrounds
..
Thanks 👍I did a little on part 2 of the weather station repair video I did (at the end where the horses came to visit ) and a little footage on the go pro camera repair video I did too 🙂
@@BuyitFixit brill I will check it out thankyou
Fantastic what a great thing to do!!, Great Channel "❤it"
Cheers Mike 👍
Well done and great result
Cheers 👍
Good one 👍
Thanks 👍
You are the best, great job.
Cheers mate 👍
Great video - very educational as always - I would be happy if you could add the solder sucker tool to the list - looks like a good one that does the job :) I have a very weak one that I can NOT use most of the time I need it. Thanks
Thanks👍. I just had a search on where I got it from and it was from Farnell when I ordered some other parts. It was a DURATOOL 908-366A-F but I've also seen them on eBay etc too.
Ha, awesome. You're a good man.
Cheers 👍
Great fix for a worthy cause. Well done
Cheers Bob 👍
Great vid. Thank you. Learned a lot from it.
What kind of camera do you use?
Glad it was helpful!
See video description, I list all of the tools I use, cameras and editing software 🙂
Another great video 👍👍
Cheers 👍
You're a good fella
Cheers 👍
Awesome ! Taking a break if your getting your arse kicked is some of the best advice you can give ! ...you no test proper.
😂😂Cheers Andymouse!
Awesome!
Cheers 👍
When the one hundred kilometer, particle collider breaks down. They need your number.....😅😅
😂😂😂😂I had someone ask if I could have a look at the "brain" of an electric train, I hope it comes off as it will certainly be an interesting video!
Das Backlight hättest Du in ein paar Sekunden testen können, sogar ohne das NT ausbauen zu müssen:
Stecke eine Leuchtstoffröhre von einem anderen Schrott-Display (wo Du sicher bist, dass der BL-Inverter in Ordnung ist) ein zum testen.
LG und danke für das Video.
Danke 👍
Excellent job!
Thank you very much!
Great video thanks! Your Sherlock detective skills are unmatched. Did you do a video on how you made your bulb tester? You live in a beautiful place it looks.
Thanks 👍I did do a schematic of the bulb tester, but it's pretty much a bulb wired in series with the socket. I explain it at the start of this video here: th-cam.com/video/aEQu1vd7OxM/w-d-xo.html
@@BuyitFixit thankies!
The correct way to test it is put it in the TV and show it doesn't work. Then they can say your faulty TV damaged their new part 😆
😂😂😂😂
I'm scared of bringing electronics home. A few years back I saw a dell XPS laptop being thrown away ! In its time that was a heck of a laptop. I have loads of parts so I bring it home and put it on my deck for the night. The next morning I found the right power cord and discovered it wouldn't turn on. Time to dig in, I remove the first cover plate (over ram or H Drive) and discover loads of freaking cockroaches 🪳🪳🪳 running over each other! It was packed and infested with them. I put it in a garbage bag and left it outside for a week. I then cleaned it up, changed out the ram and resold it cheap.
Ever use a hair dryer on a bad power supply to test it ? Someone showed me that trick on a desktop tower with bad caps.
Thank you for the tv repair video
Yes I've not had that one before. Cockroaches don't seem to common over here, or I've just been lucky and not seen a lot of them. Yes a hair dryer, and freezer spray is also handy (especially if the fault occurs when the device warms up) you can spray it on a component to cool it back down and see if the fault rectifies itself.
Looks new ... good conditions .. certainly worth the trouble to fix that .
Thanks 👍Quite an old set, but in fairly good condition.
Great!
Thanks 👍
Electrolytic capacitors are far from precision components. Capacitence can easy differs ±10% of rated value without be faulty.
As always, exelent video.
Your being too kind to them ±20% is still quite normal, for a lot of PSU's the value does not need to be very precise and ±20% are cheaper.
I never go above 80% of their voltage rating for production designs give them an easer life when released in to the field. 🙂
Thanks 👍Yes I wasn't too sure on that 🙂
Interesting. I didn't expect the tolerance of capacitors to be so great, although it's not something I've looked into before.
19:26 🤣lol Mick, I think you probably are the final boss of dad jokes haha. (don't stop please 😂)
Yet another great fix Mick 💪🏼 but I think the bad transformer from AliExpress was a karma haha.
😂😂😂Thanks 👍
Fantastic work there 👍🏼 Hopefully you’d a cuppa afterward.
😂😂😂Yes I did indeed get a cuppa or two 👍
I hate seeing things like this going into landfill so well done tracking down the fault and giving it to a deserving home.
Cheers 👍
Good job. After you replaced the obvious ones, I was betting it would be the small bootstrap capacitor.
Electrolytics are rather crude and have a high tolerance value of 20%, so 837 uF (i think it was) is within tolerance for a nominal 1000uF. Often they can keep on doing their job when the capacitance is 50% of nominal, its the increasing ESR that stops them working. The increasing ESR makes them run even hotter, so its a positive feed back.
This would have been a good one to test and compare the capacitors with your ESR meter, in circuit, versus out of circuit.
Thanks 👍a few people mentioned the 20% I thought it would be a lot lower like resistors at 5 or 10% at most. Seems I've learned something new 🙂
I've got a spare DVR with either 4 or 6 channels that I don't need / have a use for. It was free to me; if you need another one in the future, feel free to reach out and I'll make sure it's free to you as well. I'd rather it went to use than sat here gathering dust for the next 10 years!
Thank you kindly for the offer 👍I don't often install CCTV, I had just been chatting to the lady who runs the rescue centre. as I put some lights up for here a couple years ago. She asked me about 6 months ago if I could install a CCTV system for her, and I only just got round to it last week 🙂
Low esr (low impedance) capacitors required to be fast enough to smooth the power out
Yes low ESR is what I fitted 🙂
You are such a nice man :-) will you be looking at the intercom any time soon ?
Yes mate, I had been planning on getting back on with it last week, but I had the CCTV system to fit and had to stop that as was ill with the flu for a week. Hopefully I'll get back on with it this week.
Okey, I have ordered multifunction tester T7 😁
Nice one 👍Yes it's not a bad little unit.
