CRT Television Restoration, from the USSR!

[@ThomasBurns]

Thanks for watching, everyone! What do you think: should I make a Part 2 for this restoration where we revisit the sound and signal problems, and try to clean up the plastic case?

[@espelett]

Absolutely!

[@ckovalev]

Definitely do! Excited to see where this ends!

[@skeeveskeeve]

yes!

[@alyahewich3062]

YEEESS!!

[@Readbooks6800]

Yes, surely Part 2 will be deep dive .😊

[@ckovalev]

You're like a shaman working some ritual to revive a fossiled animal, Thomas! Pure magic!

[@ThomasBurns]

Hahaha thank you!

[@SalvatoreCostasowegot]

Wow! I've been always amazed about electronic restoration! My father used to teach me how to do and I see you also are doing the same! I really appreciate it. You got a new subscriber! :-)

[@ThomasBurns]

Thank you, Salvatore!

[@Nepermath]

Very good work, continue ...congratulações, i Love old tvs

[@BanazirGalpsi1968]

Nice tvlots of hard work. Good stuff.

[@ThomasBurns]

Thank you!

I like getting stuff in the kitchen sink with hot water and dish detergent and using a paintbrush to make everything clean again. This is effectively what Tektronix used to do when servicing old tube oscilloscopes. I have a tube FM receiver that smelt so bad (tobacco) when I got it that I ran it through the dishwasher a couple of times and it came up like new. Obviously have to give it a good chance to all dry out before applying power.

[@ThomasBurns]

That’s a good tip, Rich-thank you!

Hello, Just a tip for cleaning the TV motherboard. I usually clean it by removing the transformers from the motherboard and the speaker and the picture tube (CRT) from the TV, then I bathe them in a bathtub with soapy water. 3 days of drying next to a radiator and it will dry completely, it will be nice and clean. I've been cleaning old dirty TVs this way for years and it always works, I know it sounds a little weird at first but once it dries it's fine. I have several Soviet televisions, Elektronika C430 and C432, Junost 402. And I also have a Videoton Color Star television. Greetings from Hungary!

[@ThomasBurns]

Thank you! Will try this method next time!

Как это интересно получается, у меня такой же телевизор который я хочу восстановить, я просмотрел весь UT в поисках модели в такой же комплектации (их на самом деле несколько), и нашёл только одно видео с такой-же схемой, но это была разборка на драгоценные металлы... и вдруг, обнаружил видео ремонта на англоязычном канале! Чудеса!!))

[@ThomasBurns]

Спасибо что посмотрели!

[@alyahewich3062]

@@ThomasBurns вам спасибо! Я едва отыскал эту информацию! И отдельное спасибо за схему! Та которая у меня не подходит. Я бы и не подумал что это 404я модель, на корпусе то совсем другое написано.))

[@TechicallyTNT]

Well done Thomas. You've made much progress...

[@ThomasBurns]

Thanks so much for watching!

[@TechicallyTNT]

@@ThomasBurns lol I'm watching your channel even now. Lol

[@generaldisarray]

Excellent work. I love the way you treat these old pieces of history with such respect. P.S. I love the UNI-T multimeters. I have a various multimeters, but my UNI-T UT33B+ gets the most use as it's so convenient and easy to use.

[@edgeeffect]

This is great.... I hope you make more videos.

[@ThomasBurns]

Thank you! More on the way!

[@thomasmaiden3356]

Simply cleaning stuff can fix a lot of problems. "Zoe the Robot" tells me that a good cleaning allows for a close inspection of all the parts.

[@Fender9s]

So glad I was recommended this channel! so much fun to watch :)

[@davelahoud1256]

"Me being a total amateur..." My face when you heard that...

[@shivbalmiki]

Love from India ❤ You are like a user manual from which any person can understand how to handle these old beauties

[@ThomasBurns]

Wow, thank you!

[@manoflaw3485]

Well done 👍🏻 to be continued!

[@miniposeidon]

Meanwhile, I have a perfect condition CRT - remote, Manual VHS DVD all included, It all works At least the one that’s not an engineer, Dose not, have to do it.

[@paulstubbs7678]

The set looks like it'd make a nice monitor for a retro computer (preferably Soviet) However that variac looks absolutely deadly with a missing side panel.

[@ThomasBurns]

Thanks for watching, Paul! Yes I came to the same conclusion about the Variac and eventually replaced the screw terminals with a cut of clear acrylic and a standard female outlet.

[@Merkuryyyy]

Just so you know, all soviet tvs work on a very similar schematic. They are all based off eachother, but the Rubin 714D was a completely unoriginal non copied schematic they tended to explode hahha, mine already has blown up 20 years ago I have idea to restore.

[@MegaWildweasel]

for cleaning boards a tooth brush works well, with isopropyl alcohol. for nasty ones that are out of the unit you can try good old soap and water followed by IPA. then of course blow them out with compressed air and let dry.

[@ThomasBurns]

Thank you! I’m always nervous about the e soap and water approach-is it safe for things like transformers?

[@MegaWildweasel]

@@ThomasBurns it depends on how they are constructed, if sealed then yes if not then avoid the area and then hit it with ipa and a good blowing out with compressed air. ( I started out working on US Army Electronics in 1981 Ironically. ) even if they do get wet IPA then blowing it out and setting it over a warm vent will dry things out. (Glenn L.) As the boards in this case have many Coils in them I would clean with IPA. Also I noticed you are working on the tv with a metal watch and ring on. they should come off when working on live electronics. (Safety last! LOL)

[@ThomasBurns]

@@MegaWildweasel Thank you, Glenn! And thanks so much for watching!

[@davelahoud1256]

So happy to see your subscribe count soaring. Great videos mate!

[@ThomasBurns]

Thanks so much, Dave!

[@randomfiregamer3273]

"Why clean it? That's a great question, tells the machine that we care about it, makes me think we have more of a chance."

[@TheOriginalLikeButton]

Since I first saw it I didn't have much hope for it. There's a certain point [of disrepair] after which you just can't revive those old things.

[@paulstubbs7678]

Why clean it - I'd probably have been thinking of starting with a pressure washer. followed by a good stint in a very warm and dry place to lose all the water. IPA can also make a good water repellent.

[@KofaOne]

21:39, a seemingly professional technician can't understand that the mount is used as pin 5 and the same sheet of metal won't have different voltage on the other side. Soviet engineers even labeled the pins for the silly ones....

[@raphaelvogt3215]

He said he's an amateur.

[@daveloomis]

I forget, how many amps does the tweezer replace as a fuse?

[@ThomasBurns]

Hahaha maybe the guy who left the tweezers there was smarter than we think!

[@NicksStuff]

18:11 Try using the *point* of your probes to pierce the oxyde layer?

[@Fanzindel]

Someone putting a wire for a fuse might not have had access to a new ¢5 fuse

[@ThomasBurns]

Very true!

[@Fanzindel]

@@ThomasBurns growing up in last decade of east Germany and taking apart old tube radios as a child to somehow fix them (with no knowledge) I can somewhat relate. Just glad I didn’t kill myself 🤦🏻‍♂️ 😅 love your videos!! We still have a Junost S1 somewhere. Maybe one day I’ll be able to restore it with the help of your videos. Thanks for doing what you’re doing!

[@yaskulka]

Measuring pin 6 for pin 1 and pin 7 for pin 2... Cannot get more dumb than that. 19:57
