Vintage CRT Safety Lense Removal and Cleaning Cataract

[@русскийкот3343]

I greatly enjoy repairing and restoring vintage radios and tvs , its fun to shock all the antique store owners that a younger girl can do stuff like that 😂☺I am currently getting my masters in electrical engineering just from my love of repairing vintage radios and such. Also nice to see others interested in it aswell ☺

[@MissDiorsChickenFeet]

I can imagine how many hours of enjoyment some little kid got out of watching this tv!! Has anyone ever made a video comparing the picture quality of an old vintage tv compared to the modern flatscreens???

[@evil_smartrising1346]

Television and antique tech restoration is a true artform. I started when I was 14 and I would restore and sell old CRTs and cabinet stereos to antique stores for pocket money before began pursuing a career. Videos like this (and from this man himself) were a really great guide in this. Its great people still have an interest in this to actually post and watch it on the internet. If you yourself are interested in it, My advice would be to try and get this stuff from either passed on family members, or stores like Goodwill or Habitat for Humanity.

[@karlament6939]

my grandfather worked for admiral tv and radio back in the 1950s and 60s i use to watch him repair tv sets and old tube radios back then in 1967 i was small at the time ever since i got hooked into electronics thanks for the videos

[@deadfreightwest5956]

Okay, I'm a machinist, so methodology interests me greatly. I don't think that gizmo you pointed out was to inject PVA, it was to apply a vacuum. It appears from your teardown that the radius of the CRT and the radius of the safety glass is different, that is, the safety glass has a slightly greater radius so that even in contact with the CRT in the center, there'd be a gap at the outside. So they probably applied the PVA in as even a coating as possible the CRT, then pressed the safety glass on, then applied vacuum to bond the two together and remove any bubbles.

[@Wolf359HeavyIndustries]

Thank you for this documentation. Thank you for this repair. I rarely see such a well preserved cabinet and circuitry. This is not out of the realm of many learning restoration hobbyists, even young learners. Rescue it! Learn! Take your time!. Stop and keep it safe if you are uncertain. Review high-voltage safety practices! Remember that capacitors can store powerful charges! Start again when you are confident even if that is 20 or more years later. Have fun and always stay safe above all!

[@gabotron94]

Of all the nasty chemicals they could've used in that era, I'm relieved (and kind of amused) at how innocuous PVA is (essentially white glue)

[@mrKozmoz]

I find the act of restoring an old TV set to be pretty awesome. Good stuff.

[@davida1hiwaaynet]

Wow, amazing improvement. I know the feeling about who would take this sort of time to restore an old TV. Those who do this kind of work for a hobby really appreciate the time spent. Thanks for showing it to us!

This set will probably show up in a movie background in the future. Nice job Shango066. Looking forward to the follow up.......Carl

[@5speedfatty]

I love this series. all of these devices predate my birth by 50 years or more, and its really cool to see someone fixing them up to make them look and work like new again.

[@gutsngorrrr]

Nice work bringing back that old CRT brings back memories of fixing TVs and computer screens. Such a pity that a lot of the younger generation are growing up without the ability or the motivation to repair anything.

[@tristan6509]

It's impossible to repair a flat screen TV if the panel itself breaks.

[@gutsngorrrr]

@@tristan6509 That is very true and would be the same for a CRT TV. but most flat screen TVs fail because of the capacitors in the power supply fail.

[@willrobbinson1]

It looks farrrrr better now the screen has been sorted out , we don't see these sets down here in aus as we have been late in nearly all electronics down here , eg mid 70's fm radio , color tv 70's - even b/w tv in very late 1950's its truly amazing how old gear can be brought back to life

I'm glad to see that Shango wore some personal protective equipment. Had that CRT imploded, and he not had protection, he could have been disemboweled and castrated by the resultant razor-sharp shards of glass.

[@TheFurriestOne]

Man, those round picture-tubes are neat!

[@ronmccaskill2358]

If you need to separate 2 surfaces stuck together, i use a brass shim kit. The shims are about a foot long and 5 inches wide and about 10 different thicknesses and can be slid into a tiny gap and manipulated like a knife to slice glue, silicon etc. Use a thicker sheet from the kit once you can lift an edge with a slim wooden wedge or similar.

[@ArcadeDude44]

A lost art, the technicians that can repair crts. As an arcade game collector (who refuses to ruin them by placing lcd screens inside), I wish I knew a 10th of what this guy does!👍

[@Metal-Possum]

Most satisfying to watch you peel that stuff off. I've never encountered a CRT that's done this before, so I'm guessing the few I have in my collection just aren't made the same way, or have held up well over the years.

You need to look up his other channel called Mine Explorers. He goes in extremely old mines and reads 100 year old newspapers and candy wrappers. If you like this stuff you will like those videos too.

[@SRCVintageElectronics]

Wow! You did a really good job on this restoration

[@karlament6939]

that is cool to see these old vintage tv sets been restored lol

[@proxxima038]

Those old CRTs and a heat gun are not a good idea in general. Tensions in the glass due the heat can make the CRT implode. I know of guys which used the same method and that didn't end well... Flying glass and blood everywhere. Remember, the PVA and front glass are the implosion protection for these CRTs.

[@linglingjr]

Wow this was a million times easier than I imagined. I figured you'd be filling in the space between the lense and crt full of silicone and baking it or putting it under vaacum to remove any bubbles.

[@kenseabury1067]

Shango must have *a great deal* of patience, since that is a requirement in being successful in repairing/restoring these sets. I also see that he is wearing PPE (personal protective equipment) to protect himself from any razor-sharp shards of glass resulting from any potential CRT detonation.

[@td3993]

I realize that this vid is 5 years old, but I'm wondering why you wouldn't put a huge blob of silicone caulk in the center, and press the glass down on that. Without the adhesive between the two pieces of glass, you no longer have safety glass. Safety glass holds together because of the gel layer between. Without it, shards of glass will fly everywhere.

[@fryode]

I can't help but marvel at flat screens getting so cheap. My brother spent $2600 on a 26 inch LCD back in 2005. I dumpster-dived a 42 inch for free in 2009 and fixed it for $6. I bought a 70 inch 4K for $1700 in 2016 and now you can get the same thing for less than half that price and 50+ inch LCD sets are showing up at thrift stores (which don't even take CRTs anymore).

[@lylelay]

You do realize that without the PVA the safety lens no longer does it job right? This was a packaged system, like the safety glass in your cars windshield. When that tube implodes and sends glass through... where or who, ever, you will be liable. Speaking as someone who had a friend spend 4 hours having CRT picked out in the emergency room.

[@GigsTaggart]

I've broken plenty of CRTs accidentally. Its usually way less spectacular than you might think. Just hisses for a couple seconds. Lots of old computer terminals had very thin front glass and no extra safety lens. Later TV's and monitors have super thick front glass. Anyway I've cracked both kinds tossing them around and never a catastrophic implosion when they have their belt on.

[@lylelay]

@@GigsTaggart yeah modern tubes (well, more modern tubes) are much safer than the old ones. Especially if you break the neck (nipple) which is what you're supposed to do when when you release the vacuum. (fill the vacuum?) But on those old tubes there was a reason that they had a safety lens and there was a reason that they had goop in between them.

[@RODALCO2007]

Great cateract repair. Finished watching your video the next day.

[@nivlick]

That’s what sky’s looked like in early western movies. Also have you ever given it a thought of using an air compressor and air gun to help seperate the safety glass.

I don't know much about these old TVs. What is the safety lens used for?

[@elmikeomysterio5496]

Safety, duh! Lol. Seriously though, its an additional insulation and impact layer to keep you from busting the tube and having glass fly everywhere, or being zapped with a massive static load by touching the screen. Those old tubes are insanely high voltage.

[@TranscendentalAirwaves]

To comment on your comment that most people wouldn't attempt something like this the reasons aren't just that people are inept and lazy these days. Don't get me wrong, most are. But it's also because a lot of people fear CRT's because of the high voltages. So personally taking the tube out is what has stopped me from attempting to fix monitors or other things that have problems like this, plus these days it's a growing lack of interest in repairing and owning a houseful of old defunct tech. lol

How you connect the ground with that spring, if the line of dirty in the middle is the limit of the black conductive paint , I see it barely touches that area. Did you set in on the dirt where the black paint is not present (the area around the neck?)?
