So why did RCA use the thick PVA adhesive in the first place? They had foam adhesive tape in 1967. Why put a thick adhesive over the screen when other better alternatives existed then? This looks like it was planned obsolescence...
I watched the whole thing and I must say, this process DEFINETELY beats recycling these awesome TVs; they are certainly built to last. I can't believe people throw away these TVs especially when they work just fine! Great job.
A video taken of a projector screen showing a video of a television showing video of the news. Still, somehow I can see that you seem to have a good quality picture there.
That's AMAZING! I wonder now if our old CTC-17 really needed all of those CRT replacements. Seems like RCA was at our house once every two years with a new CRT. The image would get 'milky' and washed-out.
Out-friggin-standing. A real nail biter. Had I known this could be done I could have saved the school districts in south central Wisconsin a lot of money. When I worked for CESA17 in Janesville (WI) we just replaced the CRT's even though dynamic testing showed they were good. What you call 'cataracts' was a very common problem. I'd say about 20% - 25% were affected. Where did you learn this technique? Then along came the JT970W chassis that had it's share of problems. Not the CRT though.
wait, thats a tube type tv? i was wondering why it took so long to get the picture up. and is the channel display nixie tubes?? thats a nice tv set for as old as it is!
Oh my word, I was so freakin nervous watching you do this that I had to take 3 freakin valiums. I thought you were going to break the freakin thing and then with the heat gun cause you did one side and the other side was dryin! Then with that razor I was so scared you were going to cut yourself. You need to use 2 heat guns and the kind of razor that auto mechanics use to take off inspection stickers. Oh, now Im gonna have panic attacks
I definitely have some CRT's that need this done...One is a brand new never used CRT from 1977 I installed in a Zenith set and the PVA problem is starting to occur.

In other words, PVAc was a popular (and cheap) adhesive in industrial situations in the 1960's, as it is now - but sticky tape is a bit easier in application :)

Nice work, was going to order a new tube for the set, but going to restore the tube instead, maybe use two heatguns.

So that stuff between the glass and the surface that was removed was not supposed to be there? It looked like it was coming from the factory.

Is the packing tape a good enough dust seal? I've had problems using the stuff and having it dry out after a couple of years.
Thanks for a good series!

Great restoration and video series, I've watched one every day this week on my lunch break. What will I watch next week?

Very informative series of videos!
The picture looks so good on the restored set.
I definitely have some CRT's that need this done...One is a brand new never used CRT from 1977 I installed in a Zenith set and the PVA problem is starting to occur.

Beautiful restoration! The picture is probably better than new without the PVA material on the CRT.
The lens mounting is just like the procedure we use to put the touchscreens on video game CRT's where I work.
Too bad they don't make CRT's that last this long nowadays. Older CRT's had much better gun assemblies and more cathode material.
I'm glad I have my Sencore CR7000 for the weak modern CRT's I come across constantly at work. The worst ones were the early 90's Zeniths.
