Color Television CRT Cataract Removal and Replacement Pt1 1966 Sylvania Tabletop 

In my about 30 years of using rebuilt CRTs from the early 80's until the early 00's (we stocked 20-50 common sizes most of the time here in Northern California), about once a year or so we would hear a pop from the storage room and investigate and find a imploded CRT in the box. I wonder how many we didn't find that popped over a weekend or at night. Keep in mind that they were all rebuilds. Ah the good old 80's and 90's. Good job with the PPE!

All that safety gear almost looks like Shango going to the local Walmart.

"I don't follow rules..." That pretty much sums up how Shango rolls. The Subaru anti-endorsement addendum made my evening.

Now I am excited for the upcoming Colorama color experience.

I love that vintage RCA packing tape.

"I take that seriously because I only have one set of eyes and they are not yet replaceable" Is a whole mood

wowzers that looks sooo close to my familys tv we grew up with!!!!

The thumbnail alone makes this a must see video.

Wow, a cyberpunk beekeeper thumbnail :D

Been watching since your urbex days. I'll always love your eccentric way of thinking.

The only times I've ever regretted having that voice in my head saying I was about to be injured, was when I ignored it.

@ 5:35 Ya, anyone that's caused/seen a catastrophic CRT implosion throw fist sized chunks of glass 10+ feet, will usually heed any safety warnings that go along with handling them.

Nice! Your own mosquito breeding pond. You will have a lot of fun with them coming summer evenings.

Love the cataract removal vids

Wow you're a pro at doing those cataracts. That ending was funny. Can't wait to see the picture on the TV.

Shango, This is intense until you are able to remove the safety glass.

Like suit. Look like a bee keeper ready for war. Stay safe.

Im a simple man, i see a shango colour tv video, i click 'like'👍shave half a volt off the filament voltage and that colorama will last a lifetime and you can re-seal these lenses with a good quality clear silicone, it will never go bad again

From my days selling used TV sets,Colorama picture tubes were the budget model. My opinion the best were Zenith Chromacolor and Sylvania tubes. Where I live only the RCA picture tubes would get the cataracts but nothing like you get there

Pretty fascinating! Really looking forward to Part II, Mr. Shango066.

Sylvania - back when we made stuff in New York State. Mostly a memory now. (GE, Kodak, GM engine plant, IBM, McIntosh stereo equipment, Corning glass, Remington rifles, ALCO locomotives, Bell Labs...)

I imploded a couple 60s black and white crts when I was a kid. Good thing I wore nerdy glasses.

Ah man, I loved my Subaru ***hits vape***

Great video as always. Looking forward to the sequel.

Great Video, enjoyed it

if you want to fix the weird glass imperfections you could try bonding the entire thing with uv cure loca or liquid optically clear adhesive, it's what they use to bond cell phone digitizers to lcds and has a refractive index very close to glass so it hides basically any defects in the glass, you would need like 2 tubes of it at least but you put a massive blob in the middle and push down on the glass to spread it outward, then put it in the sun to cure for a day. would be really interesting to try on a crt that you don't care about that had a super easy to remove safety glass, if you want to get really fancy with it you can vac chamber the whole thing to get any bubbles out but i've found it not necessary

My Dad worked for Westinghouse from the early 1960’s to 1977 when they closed the doors. He worked in a plant that mainly made CRT’s. He used to work on a “Lear” machine where I believe is where they create the vacuum and seal the neck. He said they would implode quite often. He also said any tubes that wouldn’t pass inspection for good TV manufacturers were always bought by Curtis Mathis. He always warned people not to buy those overpriced boat anchors because he knew their lack of integrity of selling a quality product was nonexistent. Just hype!

22:37 Shango couldnt hold himself of excitement he even even dropped the heatgun!

Having it go boom with the rice crispy's crackling sound when you pour milk on them makes for great youtube content.

Good morning Shango!! I was learning electronics and one of my inspirations was you. I bought a defective transistor radio earlier a Panasonic R-1018 to practice on repairing it. Hope it ends well, sending love from the Philippines! 🇵🇭

Subaru sucks. My father inlaw had one. Hated driving it. Loud and lit would lurch every time starting off. GM, I hear you. Volt driver here. Best car ever.

Shango is having fun, in that warm California sun! Ha haha. You've got the right attitude about removing cataracts on rectangular tubes Shango.

Another successful cataract with no drama

Such a satisfying video.

Wow, new old stock packaging!

Shango all puckered up from the cataract riding that Subi vibe. You'll definitely need the vape rig living the bottom life

Glass is crazy stuff one day you can play football with it and the next day you just move it a bit and it pops, great removal well done.

Best thumbnail ever!

Wonder if they were able to get away with selling factory blemish tubes to the repair market because the bonding goop covered up the defect.

Shango tell the national weather service that they have to get their declate waxed in order to get rid of the tornado.

Love the video! It takes dedication to separate that glass front. On the Subaru, possibly tire(s) noise, it's happened to me on more than one occasion, new tires solved the issue. Sad thing is these tires still had lots of tread on them.

There are some good videos of CRT implosion on RU-vid under that search name.

yes, later crts had the metal rimband as one part of the implosion protection, other was to have a thicker glass face so an extra one wasnt needed

Wooden door shims would work great for removing safety glass and are cheap as dirt.

Rite Dude, Mr C sent me! GB :)

Thanks!

I understand. I would not want to be shot with shards of glass either. Great video, though!

Jeez, I was scared. When I saw the posted pic I thought Shango was gonna do some peaceful protesting.. If you had some guppies I'll bet they would enjoy those baby skeeters.

Go, go, go, go, go, go Go Shango it's you'r birftday, We gonna party like it's your birftday!

Keeping personal safety in mind - I'd love to see a CRT implosion using a high-speed and close-up remote camera.

I have a Motorola TV that had a cataract that was worse, it was in a flooded basement so it was full or rusty water and had flowing orange veins in the PVA glue...It looked like hell, but was a VERY easy cataract. That "white glue" isn't glue it's a extra low melting point glass called "Frit Glass". It shouldn't ever fail. It exists because the most practical way to build a color tube is to assemble the face glass, phosphor and shadow mask first, then attach the cone at a temperature that wont cook the phosphor or warp the mask...That frit glass is why color tubes don't still have the goofy metal seal around the screen that 15GP22s, 19VP22s and 21AXP22s had. I can smell that PVA from memory, and feel the slime...Kinda like most car mechanics can smell differential fluid when they see a picture of a diff. For those of you that have never smelled cataract PVA go to a pool store, buy a new inflatable and huff the smell of that then magnify it 3x and add a touch of ammonia/sour to it and you've got cataract glue.

That type of laminated screen was mainly reserved for the colour tubes. B&W tubes were mostly standard, bare glass or tension banded. There were a handful of B&W types with laminated screens, mostly moulded glass or filled moulded glass, often with lugs.

Opel corsa korno butonoonumalangoje and the RCA styer cataract.

I can smell the funk from here outside Sacramento ;-)

shango , save that safty glass c.r.t. goo to make some (deck la tay) cream for the ladies . let them rub some of that on there chest and see the age lines just disappear right before there eyes. lol

That original tube at the start looks like my first TV as a kid... Found it, begged dad to let me take it, and the tube was that bad... I could barely turn the color up.

I can't remember ever seeing a CRT with a safety shield here in the UK. Unless you could afford a Sony, the tube used to protrude from the front of the cabinet - there was no bezel. Apart from 1940s sets, we never had round tubes - always rectangular. I suppose our lawyers weren't quite as tenacious...

Another hilarious video

Great video, badass thumbnail.

Just spitballing but possibly the breakdown of the bonding agent was acidic and etched the glass, often on old camera lenses that were kept in a humid location they grow lens fungus which excretes an acid waste product that etches glass in a similar fashion.

Since the other tube is garbage, it would be nice to see what a careful rejuvenation would do to it, before you replace it. If it revives it enough, might be worthy to keep it for a future resurrection video for a TV with a totally dead or necked tube.

Shango could build an oven to put the tube in and heat evenly. Shelf in middle with slot for neck.

Tornadoes are no joke I live in Tornado Alley.

I'm surprised at the assertion that the joint between the face and the funnel is a glue joint, I was under the impression that joint is made with glass frit, which starts as a slurry or paste suspended in a polymer binder, but is fused after application, effectively driving off the binder and sintering the glass frit. Using an adhesive there wouldn't make sense from an outgassing standpoint either.

This year the mosquitos are just everywhere, because it didn't freeze for long enough for them to die out in the winter.

I feel "validated" after watching this presentation, because, on one of the last video's Shango made on a cataract / shield removal, I thought and mentioned that some wood shims, PLACED ( not pounded inbetween the surfaces with a hammer like one said I suggested) might not be a bad method of slowly and gently separating the clear cover from the CRT, and lo and behold.. that's what was done on this video. The plastic shims that are available are even a better choice, they are more durable than wood and can be wiped off and reused after a use or two on messy instances like this.

Interesting and informative video. But I will never loan you my Subaru again, ingrate.

Yes. With my morning coffee.

You should mail in the warranty card for shits n giggles.

How about an EOL on the old tube?

that picture tube was "squealin like a pig"

I bought a new Sylvania color tv in the 70s. Brand new it had an awful picture. Never The Same Color!

Drove an almost new Subaru of that type (15k miles), Forester i think. The drivers side roof pillar was howling like bad wheel bearings.

I use pumice and toothpaste to remove glass imperfections.

Nice !

You're a braver man than I am. :)

Good morning!!!

I live in Tennessee. I was between that tornado and Nashville when it happened. I couldn’t even make detail of that CRT. It was bad.

You're right about Subaru drivers😄

Another decent color picture tube was the RCA Hylite. I wonder if B&W picture tubes get cataracts also?

crepe-tastic sparkle pony masterCard

that 'discolouration' dull area could likely be polished out with tcut or brasso...

SHANGO!!!!!

I would like to see you rejuvenate a picture tube several times to see how good you can get it and if it burns out oh well try low rejuvenation and high rejuvenation would be interesting.

Run into your safe place. We're alarming the sheep again.

If the Subaru was a hatchback, that would be a plus. And for those West Virginia winters the all wheel drive.

A color TV from 1966, roll out the red carpet.

Um... Im pretty sure those little "zig zaggy" things in the water are Mosquito larvae... lol. That's why you want to make sure there's no standing water around outdoors... Its just a mosquito breeding ground.

I thought I was the only one who felt that way about Subaru's. Not all Subaru drivers are bad but many bad drivers drive Subaru's, at least in the East.

those era subarus always need wheel bearings and cv axles Funny how many cars are out there now with absolutely zero redeeming qualities. Bloated on the outside but cramped on the inside, heavy and sluggish but with 'sporty' and rough riding suspension, an electronic throttle pedal that gives it 100% TPS at 5% pedal input to make it feel "spritely", overcomplicated trash engines and tires with tiny sidewalls for all their faults... But people buy them by the thousand.

Lol. Subaru almost always takes first place in customer satisfaction charts in the auto mags. I ask myself "why?" since 40 years.

I wonder why the red gun is always the one that shows more signs of wear, even on "new" in-line gun crts

Acetone, rubbing compound.

As a Britisher, I cannot believe a car can only report around 20 MPG at that speed with just a Shango and a TV onboard :o I know that people like their big engines and things but, well, we really need to find better alternatives to this just to get around!

I bet that bearing noise in the Subaru is the carrier bearing for the rear driveshaft. And I wonder if that blemish on the glass is from the decaying epoxy, maybe it gets acidic as it breaks down? (not an expert)

Lol got an ad from utube about a conference in Detroit on may 21-25

I agree with you about Subaru , BUT I would rather be driving a Ford ! Great Video !!

Some will say that LCDs are better in coin op Arcade refurbished consoles. Nothing quite beats the CRT they were made to be 640x480 there is a huge market for arcade console collectors that need CRTs its really sad they just stopped making them completely. Its damn near impossible to find a vector graphics monitor

If you consider that Subaru excessive noise-wise, there is a world of economy cars out there which will make this Subaru look average or above average. Just increase the volume on the audio system and live with that. At 160+km/h I can't hear my own thoughts and my way is to blast music to keep myself sane.

Shango better armor protection from explosions than a ruzzian conscript.
