This was part three of the Packard Bell, part 2 will be out in a few weeks.
Nice video like always. But did you use a different camera or did youtube do something to there coding system? I see a white/light halo affect around the black paints-tripper that I never noticed before.
I see it has red, green, AND blue transistors in it.
I only like sniffing Smellovision...Not Sniffovision! I might smell sniffovision but I never sniff it! Don't picture tubes blow in and not up? After all , they are vacuum tubes.
If one looks closely with a microscipe or more powerful magnifying glass, can one see a few of the things that this tv broadcasted from the past?
Can you actually cut a hole in the top and make the tube itself a fish aquarium?
Vacuumed pressure tube, reminds me of Futurama. Always made me chuckle.
Fry : How many atmospheres can the ship withstand?
Professor Hubert Farnsworth : Well, it's a space ship, so I'd say anywhere between zero and one.
So spaceships are technically non-binary then?
@@gavincurtis Are you assuming it's gender??
@@fryloc359 It says it is anywhere between 0 and 1.
so it's all of the binary?
@@gavincurtis they usually sit at 0.3 atm any lower and the crew starts to worry
I seriously am interested in how it smells...considering how different older plastics and chemicals are like.
Given the chemicals they used back then, it's probably toxic and would kill you.
@@michaelbianchi22 It wouldn't kill you, wtf. You'd need a massive exposure to get killed by anything inside something like this.
would be interesting to try loca, liquid optically clear adhesive as a replacement, uv curing and basically identical index of refraction to glass.
might be able to even pump it in and then vacuum degas the entire thing in a big chamber
I was just thinking about that. There’s not too many people interested in these old sets though, so the cost per set and setup would be prohibitive. It would be one hell of an experiment on a smaller CRT.
Only if it doesn't go opaque in 50 years time!!
I was wondering what his solution would be, and almost shocked he just left it at an air gap. Obviously people aren't too worried about visual fidelity with these old sets, but you're definitely losing overall image quality and viewing angle without some kind of adhesive ensuring continuity between layers. Also a chance for dust and other particles to accumulate between the layers. The restoration effort is INCREDIBLE though, so I guess we can't complain too much haha
“You can see it divorce!” Well, yeah, but the other side wasn’t signing the paperwork without some more persuasion.
Always wear protection during a divorce, a lawsuit isn't out of the question.
Hi Shang0. great job and explanation. Every time I see one of these sets,I am reminded of My older brother,who passed about three years ago, from MS. He loved these old tube sets. Has do I. Thank you for bringing back some good Memories. All my very best.
There are several great videos on YT showing how violent the CRT implosion is for anyone interested.
I have been dealing with CRT sets for over 50 years and so far have never had an implosion, by accident. I did shoot one with a .22 when I was a teenager. It was in a landfill and about 50 yards away. Glass was falling behind me. Never did that again.
Was that black/white, or color?
@@onradioactivewaves B&W
That's going to look much clearer than any attempt to replace the rubbery fill would have accomplished. I'm never comfortable leaving irreplaceable color phosphors in sunlight but it looks like the heat helped.
Never get tired of watching You do cataract surgery over the years always a good video even though nothing has gone wrong in your videos but you never know
Shango: "It's Free! You can see it divorced." Me: don't look now but the PVA glue is demanding alimony...
I don't see a safety issue with removing the glue and siliconing. There were 2 round CRT types used interchangeably circa 1964 the 21FJP22 which use the cataract glue, and the 21FBP22 which had NO glue but instead a rubber gasket around the edge and an air gap in the middle (the mounting flanges pressed the safety glass on). What you've done is turn a 21FJ into a 21FB. Both CRTs were safe enough that they were used interchangeably in sets for years. The tube charts in the sets and Sams would call out both types as valid replacements. It'll be fine safety wise.
It's better to be safe than sorry and this is a public service video, what do you expect the guy to do ? quote numbers and say 'it'll be fine '
@@andymouse No, but Shango obviously didn't know about this. Good info for me.
A LOT of patience is required for this job.
Excellent job explaining the process, risks, and benefits of cataract removal!!!
Man that was one hell of an outro I don't think I can recover from that one.
So cool to see this transformation. Great stuff, Shango.
The divorce happened, but there was still a custody battle
Multiple heat guns and many hours here in the UK !....cheers.
Probably it could be removed on cloudy or rainy days, then you would have advantage ;)
Yeah the sun works great if you're in LA
You’re the best at removing, and re-installing those safety screens on and off of CRT’s. Your friend, Jeff.
As always good info, especially staying covered up in case she blows.
What ever became of smell- o- vision? I was looking sooo forward to that.
Well, in 98, there was iSmell, but it flopped when tons of scents got made that resembled farts and dead animal smell. You probably could get a tube of PVA scent for it though!
The earliest versions of Smell-O-Vision were scrapped during testing in late 1963. Zenith, the company testing SOV, was once asked what happened and they simply responded with a short quote about "unintended consequence". It was noted that all television sets sent out for testing were returned almost immediately after the Zapruder film was shown on national television. Although, it's unclear if this is merely coincidence or not.
That's how Captain America got his shield.
Wow, looks brand new now! Amazing procedure on how that's done.
"There It Goes! It's Free!" ........ "hnfff ... You Little .....hnfff... The Hell .... hnfff "
...... "You Wanna Play Like That, Huh" 😆
What a beautiful set, can't wait for part 2
Great work as always. You do such a good job at getting these old TV sets working again. I still find it interesting that circular TV screens were once a fairly common sight.
i love watching you do that never get tired of it nice looking old tv.
I found an RCA Victor "Foreign Correspondent" 14X from 1940. Can't wait to work on it. Love your vids!
Anyways Im going to wrap my head with this, That sir was classic and made the video worth the watch. Love the Narration. KEEP IT UP!!!!
What a cool process !!!! Thank you for sharing it !
Smells pretty good. Thanks! I have cancer on my cancer now.

I'm curious... Have you ever thought about sticking these tubes in a 220F oven for an hour or something? It seems like that should be "enough" to get the lens to slide off easily.
More satisfying than watching paint dry or pealing off those plastic thingy's off of screens & things!!!! Have you ever had one pop on ya??
Very interesting! I had no idea this could be done!
Thank you. Your cataract removal videos always Rock👍
14:48 You can hear the sloppy gloppy let go of the CRT. How cool is that?
Great, but I thought you were going to demonstrate the set. Video feels cut off.
The end is hilarious.
yeah i got blue balls over here
As usual, well done Mr. Shango!
Great video. Goes to show how advanced televisions have become. Now if we could only get good programing like what we used to watch on these tv's .
"Ok that's good..."End. COOL video I had no idea the used this stuff or that they even had epoxy clear enough to use back in-the-day.
great job fixing the crt's cataract issue
Nice edit on the glass knocking sound comparison.
I like those TV sets.
Wow! This is ART!
I'm really glad to learn so much about feminine hygiene you know I just learned that always has these new things called Ultra Thins and they stop your box from smelling bad when you're on I guess a leaky day.
I really appreciate these commercials for being so darn informative if only I had a use for these wonderful products I wonder if they'd be good for oil leaks? LOL
Thanks for the great video!
Εισαι πολυ καλος και προσεκτικος Νικος
Thanks for another great video shango
These old roundie tubes are always a treat to see. I have to wonder why they seem to be more prone to cataracts than rectangular ones though.
I can always count on Shango to bring the deadpan.
That “vacuum filled pressure bulb” sounded like a warning for heating one of these things up
Super Excellent job. In my book you are the bestest.
I love the 4 quadrants marked off with the chopsticks that made a nice "Unit Circle". Plot the sin wave graph while it peels off. π2 and it's a full cycle. Cool.
This comment made me want to throw up.
Man almost a whole week until another @shango066 video.. almost thought was gonna need rehab from withdrawals!
Amazing. Loved the video and the humour 😁👍🇦🇺
Ever tried liquid optically clear adhesive (LOCA)? It's a UV curing optical adhesive, often used for phone screen repair. (why I know of it)
If it didn't work out, it'd be much the same procedure as this to remove it. Could also practice with panes of glass.
I didn't know that round tubes were still being used in the 1960s...nice looking set.
Oh yeah. Some late as '70 for cheap models. The rectangular color tube was created by RCA in the early 60s. For black and while sets, roundies were out by 1950, but there are exceptions.
Shango - Reinventing language as he goes. LOL.
Nice job, Looks like new.
Thats his styer 😀
@@Flexin010 LOL.
Shango's 3D house of cataract removal
Lovely set
This TV is so beautiful! It’s sadThat TV from this era are getting more scarce by the day.
I have seen this procedure on this channel before I think, but I didn't know there were different styres of this kind of lens! I'll leave it to the pros, not a TV collector myself :)
People dont worry about not having the "protective crt layer" here in the UK we never had them from new. shango with this removed see if you have any chemicals that will break it up so next time you can experiment.
Actually we did, from about 1962-ish onwards. That’s why TVs from before the 60s had a separate glass sheet over the screen. Once bonded glass to CRTs became a thing here, glass window sheets on TVs became unnecessary.
@@stickytapenrust6869 Oh didnt know ive never seen one, round crts were also a big rarity unless you got a set from the early years like the 30s/40s i can only remember as far back to the days of reddifusion sets
@@Synthematix You will have seen one. Even up to the last CRT sets there was always a layer of safety glass bonded to the CRT face. It’s just we live in a milder climate so it’s much rarer for the safety glass to become unbonded from the CRT face like this.
@@stickytapenrust6869 No, bonded glass became obsolete when they invented the metal stressband around the rim. In Europe we never had round colour screens, and the b&w in the fifties had a separate safety glass.
@@telocho most do but some dont...for example i have a saba tv from the 50's and it doesnt come with safety lense...its an old 90º deflection tube so...safety lense was more like a gizmo to give peace of mind to worried people...not really needed
I need advice! I’m going to try and remove the cataract of a Packard Bell 1957 tv. It looks like one solid piece of glass all the way back to the tube. How to I cut the glass around the edge???
Thank you for the correction in the implode/explode , its the one thing that triggers me to shout at the screen lol
Wow, what a difference. I had no idea there was that goo in there, always thought it was something even nastier.
17:12 Welcome back to another Ken Domik CRT review! Just for you, and just for you!
I recall a 23EGP22 going ka-boom on Doug Harland, a number of years ago (during a cataract removal attempt). It's a thousand wonders he wasn't hurt.
10:36 a thermal blanket would work too. I usually use one whenever i recuperate the "lenses" off old tubes. With the caveat that one should be careful to heat up the whole thing, there's a risk of cracking them due to the different materials, i've cracked at least 3 so far.
What a difference, it looks like a new c.r.t :-D
Great result wow.
Just wanted you to know (I live in UK) that your videos are the best out there. Think its your dry humour...
17:45 kinda looks like Texas. Beautiful conditioning, looks amazing.
Didn't think the fingers would show without the chopsticks, well done
Just did my first one of these today. I must’ve gotten really lucky because as soon as I put the chop sticks in it the whole thing just came off and the glue peeled off in one chunk
Watching people use a heat gun is interesting. How they do it cracks me up.
I'm an eye doctor, I operate cataracts and I'm 99% sure RUclips recommended me this video because of that xD
So any one have advice on where to sell a crap ton of tv tubes and electronic components aside from ebay? RUclips is proving to be a hassle for trying to get a hold of anybody.
Glad to have found this channel, love working on "vintage" electronics and love to know that there is still a niche for this kinda stuff
Love smelling old ass glue xD Amazing videos good sir, love your methods and knowledge.

saaaaaaaaaaame
Great video as always Mr S
I'm glad I got that smell-o-vision app
Only technical video which asks the question "Here, You wanna smell this?" lol
Awesome!
4:30 Glad to see someone's saying a reasonable warning. Usually it's "don't EVER touch that, YOU WILL IMMEDIATELY DIE"
At this rate you might as well open shop as an optical surgery center. 😉
@William Mulvaney …which all of these TVs are.
I wonder if leaving a heating pad set to high on it for an hour or two would help accelerate the delamination.
or make up some sort of round "hot box" with radiant heat bulb to sit over it?
Me love ❤️ Shango066 videos. Please make more videos it makes me feel bang bang good.
17:55 We're GOING TO WAR! With this CRT! That sucker almost came off in one sheet!
i had this same problems with some philips crt's except the glue was even more sticky and even let out some corrosive fluid to the chassis and pcb. To me it seems to be sort of polyester/osmosis problem like you find in boats. I glued the panel back on with an optical clear led coating from electrolube(polyurethane). Only problem i had was some tiny air bubbles from the mixing but you hardly see it when you look at the screen. (but then this was a computerscreen only used for data).If you use the original package from El there should be no bubbles in the mixed PU.
have you tried tec7 glue or the same glue that car front glass uses? both are a bit like rubber and are very good
Great video! But I wonder, could you use a clear vinyl shower curtain, laying it on the picture tube after cleaning well, then reinstall the glass screen, then trim the vinyl around the outside edge !
I notice that the lens has a matte finish to it. I wonder if it would be beneficial for viewing to take the time to use some kind of polish to it front and back to take out the translucency and make it more transparent? Would it help, or would it cause any dirt or scratches to become more apparent?
I'd be concerned about reflections. Both reflecting the room, and reflecting the CRT back on itself creating a double image.
Poly Vinyl acetate.
Acetate...
Acetone might dissolve it...
Ya I was thinking of leaving to soak in acetone..
what if you don't sillicon the glass back? will it work?
I'm sure it would work fine. Probably even be a little bit more clear of an image on the screen even. But no telling how strong that CRT glass is. These were made with the safety glass in mind so the CRT glass itself may be thinner than that of say a CRT from a tv made in the 80's or 90's since they don't have that extra layer. Secondly, the CRT may not even fit back in the cabinet properly with that extra layer of glass off. It would need something to fill in the extra gap.
"vacuum-filled pressure bulb" !
I wonder how long CRT televisions were manufactured with safety glass for?
Do you have to use a lens or could you put it back together without one?
HI SHANGO!!! Love the videos!! Revisited the miner channel a few weeks back. Thanks for all the content.
Did the "square" pictures tube that came out later have this issue?
