Repairing A Dumpster TV, And Donating It To A Great Cause!

[@SlartiMarvinbartfast]

Great job, also very nice of you to donate the monitor to a good cause. This world needs a lot more people like you.

[@BuyitFixit]

Cheers 👍🙂

[@CallumRepairs]

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.

[@BuyitFixit]

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 :)

[@ethanclement9647]

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.

[@BuyitFixit]

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.

[@ethanclement9647]

@@BuyitFixit Nothing wrong with a new transformer either. I'm glad flat screens now use LED's. LED's certainly aren't without their failures either however. Cold cathode lamps are certainly built to last.

[@carltonlane8931]

Good video,great big heart you have,thanks for the donation to the dog shelter.

[@BuyitFixit]

Thanks 👍Yes, I didn't really have a use for it and they needed one so it worked out well 🙂

[@BruceBoschek]

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).

[@BuyitFixit]

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 🙂

[@Google_Is_Evil]

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 KZbin, but it might be easier and even sometimes cheaper to just buy a whole circuit board.

[@BuyitFixit]

Thanks 👍Yes sometimes it's a lot quicker (and possibly cheaper) to replace a board, but where's the fun in that 😂😂😂😂

[@ISquishWorms]

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.

[@BuyitFixit]

Cheers mate 👍Glad you enjoyed it 🙂

[@brianwood5220]

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.

[@BuyitFixit]

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.

[@tinmantruckin8398]

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!

[@BuyitFixit]

Thanks 👍

[@TimDyb]

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!!!

[@craigcousins6718]

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

[@BuyitFixit]

Thanks and very true 👍

[@j.f.christ8421]

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.

[@MaxStax1]

As an old dog i appreciate your kind donation to the local dog rescue center! WOOF!! 🐕

[@BuyitFixit]

😂😂😂Cheers 👍

[@generaldisarray]

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.

[@BuyitFixit]

Cheers mate 👍Yes she was going to buy one and I had this one on my bench, so I thought it would be perfect!

[@roy2689]

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...

[@BuyitFixit]

Yes, great when it all works out 🙂👍

[@manolisgledsodakis873]

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.

[@BuyitFixit]

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.

[@terrym1065]

[@BuyitFixit]

@@lmwlmw4468 Thanks 👍yes I didn't realise 20% was normal. I thought it would be more like resistors with 10% 5% or even 1%

[@iNireus]

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 😅

[@laserrooster]

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. 😅

[@BuyitFixit]

Thanks 👍🙂

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.

[@CallumRepairs]

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.

[@BuyitFixit]

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.

[@ralphj4012]

@@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 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.

[@309electronics5]

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

Serious diagnosis. Well done.

[@kellyeye7224]

ISTR that larger value electrolytics have a tolerance of +10%/-25% so 800-odd uF for a 1000uF capacitor is 'acceptable'.

[@BuyitFixit]

Thanks for that, yes a couple of other people mentioned similar. I thought the tolerance of them would have been much less, something like 5% or 10% at most.

[@foseco2109]

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.

[@309electronics5]

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

[@colinboneham7387]

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!

Electrolytic capacitors are far from precision components. Capacitence can easy differs ±10% of rated value without be faulty. As always, exelent video.

[@TheEmbeddedHobbyist]

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. 🙂
