As an RCA TV technician for 33+ yrs, this video brings back tears of nostalgia. What this person did in the video; I have done thousands of times. Wow. I am now 89 yrs old and retired many years ago. Thank you kind Sir for taking me back to an incredible era; that is now long gone. One piece of trivia: Even though we have HDTV now; with crystal clear, awesome fidelity and no snow and lines, etc; they are not able to bring out color naturally; as those old analog CRT (cathode ray tubes) did. Of course most do not notice this today; because they never saw them. But IF you're old enough to go way back, you know how beautiful the color was with those wonderful cathode ray tubes; rather than solid state LCD TV's. Over time the engineers will make HDTV natural. we just don't know how long before they do it. Oh well. Thanks again for this video.
You're absolutely correct. I was too young, but ASI said, elsewhere, I remember my grandparents' TV, and colour on them was beautiful. Today, I've got A UHD 4K HDR, and though it has an amazing colour gamut, it's still not (yet) fully as you mentioned, but I must say this; the way shows off that era were designed (and I'm taking about colour schemes used in the sets and costuming) were done much differently than today. I understand why it was done the way it was, and why a more...'natural' approach has taken over. However, I'm not a fan of most... current shows - I've always preferred things from earlier eras, and in (colour) TV series, it's those drum the 60s and 79s, and film it's B&W, and for colour, I'm a sucker for Technicolor. I say this, because when I watch those old (colour) shows in my 21st century screen, they can look beautiful, as I've worked hard to adjust my colour parameters.
This guy is fantastic !!! He sounds like one of my early 70s Trade school teachers and looks and dresses like a 1960s TV repairman right from central casting !.. This is my first time watching his site and I'm guessing he is going for that look ? Either way I love this stuff. Thanks for doing these.
I spent a lot of time as a kid and young man sitting in my grandpa's TV repair shop watching him work and listening to his stories. He would tinker a little then sit down and talk, then tinker some more. Good times.
Really cool subject matter.. Not only would you have been a top notch technician 45 years ago, but you've also managed to achieve a retro look for yourself to match the era. Very cool.
I remember doing setups on televisions in the 70s and 80s. Man, I'm glad I don't have to do that anymore. The sound of the flyback buzz brought back some painful memories.
My boss used to have me drip hot glue all over the flyback to dampen the buzzing. I don't know if anyone else used to do that, but he was the boss and that's what he had me do. I always thought it was amateurish, instead of just ordering a new flyback. He wasn't born in the United States and he used to do some third world repairs, to save money, like re-winding transformers by hand and making his own capacitors and resistors.
@@JENDALL714 don't know if you'll see this, but that's a gimmick people do with arcade CRTs. they stick toothpicks in the core to dampen the ringing. I've never needed to do this.
Watching your videos made me miss my grandpa, he use to repair televisions to back in soviet union. He passed away when I was 4 so he never couldn't teach me all this knowledge about tv's and old radio technology :( Anyway your videos are really informative and I like em. :)
I love that everything in your shop including the signage is authentic early 1960s. The 1960s produced great looking and great working American made products.
Great video! I came upon this by accident, but was surprised at how these TVs can still work so well after a great deal of time-this goes back to my high school years. Thanks so much!
For a TV that old, the cabinet sure looks like it's in great shape. Of coarse TV's back then were not just for watching, they were living room furniture.
This guy reminds me of my instructor back in the late 70's ! A young Charlie Cave CET! Charlie taught me everything that I know! Great guy, and a great friend throughout my carrier as a TV tech! RIP Charlie!
It's amazing how much of a good guide this is. The same principles can be applied to most CRT TVs/Monitors and the procedure is very well explained, especially the purity adjustment. I actually used this video as a guide many years ago when re building an arcade monitor. Back when there wasn't as much of this stuff on youtube.
Nice video Doug. I have a 22" 1967 Zenith color set with its original stand. Just got finished with it a few weeks ago. Needed a full recap and a cataract removal but all is well now. it's going to be my kitchen TV
Excellent video. Please make more they are really educational and entertaining. I am actually blown away, and how well thought this Zenith television was built especially all the considerations made for service, quite extraordinary, considering how old it is.
Wow this brings back memories my grandfather was a TV repairman back in Elmhurst Illinois and it was just a thrill to watch him fix them and do just what you were doing he actually bought me a Heathkit Back in 1970 and we built it together
Its a dying breed. Good to know the skill set is still alive. I am sure there are antique collectors out there. I myself one of the last tube tv's produced just for keeps. It now all looks vintage. I also have a atari 2600 and original nintendo connection.
Thanks for keeping old technologie up an running. I truely admire anyone who invests their time into conserving knowledge and spreading it so it won't get lost. Keep up the good work!
Very interesting, my brother was a tv tech in Chicago Heights and Matteson, IL in the early 60's before becoming a fireman. I wish he was still around to see your interesting videos.
You remind me of a math teacher I had. He did math for the sake of school, but on the side, he was a vintage television buff, always going on about how the color red just don't look how it used too. He looked just like you too. He was one of my absolute favorite teacher, and how right he was! The color red IS in fact different than it used to be.
You brought back a lot of memories to me of my Heathkit days! Put together their color TV in the mid 60's and had to go through this procedure (along with several other steps) to get the color alinement just right. The instructions were quite thorough and complete with a BEAUTIFUL picture, just in time for the Rose Bowl parade (don't remember the year).
This is awesome that you have the skill of restoring these vintage TV's. A great instructional video on the proper way to realign color TV's. I still have an 1969 RCA color TV (forgot the model). Your restoration work is excellent...keep up the good work!
This is an excellent primer on color TV setup! It seems much easier to understand once one can see the visuals. I love your videos, they are great for the beginning or intermediate electronics hobbyist & collector.
I enjoyed watching this. I used to watch my father work on TVs in the late 60s and early 70s but he would never explain what he was doing. That's awesome having a 45 year old TV that still works.
Boy does this remind me of the family's 1972 Sylvania 25 inch console TV. Always amazed at what I learn about TVs by watching your videos. Thanks for posting! :)
I accidentally came across this video and wound up completely geeking myself out on the whole thing (I'm a geek, just in different areas). Awesome work, and what a piece of art those things were! Also, I learned something and that's always good. Cheers!
My parents bought one of these in '65? and it lasted -with a bit of maintenance -until like 1985, when I believe the crt croaked? what a great set - nothing like Saturday morning Bugs Bunny Roadrunner Show in front of one of these babies.
Zenith was always top notch. Having the dynamic convergence in front was a good idea. I recall that RCA would use an offset bracket on the convergence board, you would remove it, flip it up so it was accessible from the front.
Back when TV's were not only living room furniture, they were actually designed and built in the U.S.A. made to last for many decades if cared for and maintained properly. Nowadays the new fangled 70 inch flatscreens are basically disposable items.
I appreciate your going through all the steps necessary to set, align, and converge the tube properly. Very informative. I would love to see a similar video, only for newer TVs (say mid to late 80s to around mid to late 90s). Though, I suspect much of the procedure is similar, except using convergence rings, and convergence strips instead of a convergence clover and subtleties like that.
We had a 1968 Zenith Console set like the one shown. I remember the VHF Channel Selector knob and the three color control knobs below the tuner. We had the set until 1981, replacing it with a 25 inch solid state Panasonic color console with remote control. So the Zenith was with us for 13 years. When I worked with my Father on our older Black and White TV's in the days 1950's and 1960's replacing tubes and picture tubes. Our 1955 B&W RCA TV console was 27 inches, a 27MP4 model picture tube, about $150.00 to replace it in the late 1950's. I remember the Sams Photofact guides back then.
This is a fantastic demonstration! It also reminds me of my childhood. But for a few dollars more a brand spanking new TV could be purchased with at least two times the screen size!
Had an RCA we had owned less than a year...beautiful picture and cabinetry...had lightning run down a tree just outside...repairman tried every degaussing trick he knew...it never was much of a picture ever again although we kept it several years. .
Well, I did not think that I would spend 20 minutes watching someone setting up an old TV, but this was entertaining. I am surprised how nice that TV picture is.
😊Good Job, Zenith Color TV 📺 B&W , Radio 📻 Stereo ' was the best you could get back in the day !!!!!! Hope you can have something new soon, again Good 👍 Job !!!!
Another very informative video! You have a very cool channel, I look forward to your videos. Also, I think the test gear is every bit as interesting as the TV's!
Excelent top notch instructional, Kudos! Liked the whole 60's feel you put to it. Brings back fond memories of my TV tech days, some of which I still venerate and practice. I currently have a '69 RCA that works great, but is stored away. After seeing yer vid, I'm inspired to bring it out of hibernation. Nuth'n like the classic TV's.
Nice video Doug.Remember doing this with our old Electrohome console which was the first colour tv we owned.We had rented a Zeneth colour table set then my parents bought the Electrohome which was a demo.Not sure if the Electrohome were sold in the United States or not but they were the one of the largest manufacturers of tv's here in Canada.But like Zenith they were pretty much toast come the early 80s.
I really enjoyed this video. I just purchased an RCA Darcey model 211CD875 that looks almost showroom quality for $60. Neither I nor the person who sold it to me has plugged it in. I also haven't removed the back yet. Although I've done some limited work on color TV's I intend to do some research before I get into this. I will open the back soon and at least clean it up inside. I also have a tube tester & a picture tube tester. I'd love to see working but I'll be patient for now. I believe it's from about 1959.
I live in England and my family’s first colour TV was a Sony. I understand that the Trinitron system simplified set up, produced a much sharper picture and made CRT TVs so much more reliable...

This was super interesting to witness and I'm happy there are people out there who still understand how to maintain this technology! I rue the day CRTs no longer exist Q_Q
This was awesome to see how it's done. Now I know why my Dad would hit me when I played around with the settings, lol. Not to sound like a creep, but glad to see your face again, lol.
I would imagine that Nordmende doing this back in the day would had done purity and convergence adjustments in a dark room with special optical instruments to ensure the absolute best possible color reproduction.
Some of the newer disc players come with a feature that allows you to use grey instead of black when watching anamorphic movies. It prevents burn in because it's less contrast.
Wonderful to find videos like this one. Technicians with the knowledge, skills and equipment to perform such work are scarce. One question, though: Why don't you position a mirror in front of the screen while making adjustments from the back of the set?
Is there a reason that the sound on the TV is on? We really don't need to hear all that buzzing. Good video, I cut my teeth on the old tube sets, and work on vintage video equipment on my channel too.
I would put LED and LCD at the bottom at the same time. I just got a similar TV from drh4683 that looks like this one but the legs are a little different, but it seems to produce a well defined picture and it is much better than the piece of junk flat screen that went out on me after a few weeks.
Enjoyed reading your comments about TV technology, the old 1960s dinosaurs versus the new HD sets. It makes me laugh reading these sentimental comments about how much better the older sets are than today's technology. I don't think these people realize how expensive and out of reach color TVs were to average people in the 1960s. Both my parents were teachers and we didn't own a color set until 1972. Not only are today's sets superior, they're a lot more affordable to the average person.
Interesting. But you could have turned down the volume on that TV during this video (or disconnected the speaker) to avoid hearing the annoying "screaming" and "hum" of the video signal bleeding into the audio amp section ! Geez.
How at your age do you know what you know, the reason I ask this question is because is I worked at a Shop that was a Zenith warranty center you know what you are talking about , I’ve Evan learned a lot of this from you channel. Do a video on how you learned what you know because it’s spot on.
Remember, straightening out the blue horizontal convergence lines involves using the static convergence. Straighten the blue, ignoring the static convergence.
stuff i learned in high school. we could take classes at james rumsey vol-tech in high school. high school electronics. i did these things to tvs before, @1978.
I was able to filter out the annoying TV whine using the Realtek HD Audio Manager from the Windows desktop tray in the lower left hand corner. Use the graphic equalizer and bring down the middle ranges. It's worth the trouble for the information on this video. Arrange the slide bars so it resembles a "V"
20:31: It’s interesting when you turn it off it’s three colors blip out at once but the remaining colors comeback in the middle as it blows away like the wind

true true
Ya, I'm guessing he did radio or voice over work in the past.
This televisions are high quality and videophile
he looks 50's not 70's
did a lot of setup in tech school
I spent a lot of time as a kid and young man sitting in my grandpa's TV repair shop watching him work and listening to his stories. He would tinker a little then sit down and talk, then tinker some more. Good times.
This sure brings back memories of the TV guy coming by whenever the set needed working on. Back then, it all seemed like rocket science.
Really cool subject matter.. Not only would you have been a top notch technician 45 years ago, but you've also managed to achieve a retro look for yourself to match the era. Very cool.

Wow this brings back memories my grandfather was a TV repairman back in Elmhurst Illinois and it was just a thrill to watch him fix them and do just what you were doing he actually bought me a Heathkit Back in 1970 and we built it together
By far The best explanation on tv convergence I've ever seen!
Its a dying breed. Good to know the skill set is still alive. I am sure there are antique collectors out there. I myself one of the last tube tv's produced just for keeps. It now all looks vintage. I also have a atari 2600 and original nintendo connection.
True professionalism Doug! One of your best videos on tv repair yet
Thanks for keeping old technologie up an running. I truely admire anyone who invests their time into conserving knowledge and spreading it so it won't get lost. Keep up the good work!
Outstanding video, very well documented and brought back some great old memories.
Thanks for the Blast In The Past!
Great job, "Mr. Repairman"!:) Thx for taking the effort to share this awesome "history".
Man oh man the memory's of TV when it was fun and Beatiful to have one in your home!! :)

I'm so used to it I guess, however, my camera tends to really make it sound loud and annoying as in reality, my volume control wasn't up too high.
I appreciate your going through all the steps necessary to set, align, and converge the tube properly. Very informative. I would love to see a similar video, only for newer TVs (say mid to late 80s to around mid to late 90s).

Thanks for this video, it has been the single-most helpful thing I have ever seen on this topic. Really helped me a lot man. Thanks!!!
Excellent demonstration, I learnt a lot from watching that video. Thanks very much.
We had a 1968 Zenith Console set like
the one shown. I remember the VHF Channel Selector knob and the three
color control knobs below the tuner.

replace it in the late 1950's. I remember
the Sams Photofact guides back then.
A very informative video about servicing a vintage Color TV.
This is a fantastic demonstration! It also reminds me of my childhood. But for a few dollars more a brand spanking new TV could be purchased with at least two times the screen size!
Great demo! The owner is really gonna love the end results.
Very cool set and nice picture quality. Cheers! 🍻-Al

FANTASTIC!!!! Have a great hug from Brazil!!!
Another very informative video! You have a very cool channel, I look forward to your videos. Also, I think the test gear is every bit as interesting as the TV's!
Good information on setting up the tv very much appreciated.
Excelent top notch instructional, Kudos! Liked the whole 60's feel you put to it. Brings back fond memories of my TV tech days, some of which I still venerate and practice. I currently have a '69 RCA that works great, but is stored away. After seeing yer vid, I'm inspired to bring it out of hibernation. Nuth'n like the classic TV's.
Nice video Doug.Remember doing this with our old Electrohome console which was the first colour tv we owned.We had rented a Zeneth colour table set then my parents bought the Electrohome which was a demo.Not sure if the Electrohome were sold in the United States or not but they were the one of the largest manufacturers of tv's here in Canada.But like Zenith they were pretty much toast come the early 80s.
I really enjoyed this video.
I just purchased an RCA Darcey model 211CD875 that looks almost showroom quality for $60. Neither I nor the person who sold it to me has plugged it in. I also haven't removed the back yet.

I live in England and my family’s first colour TV was a Sony. I understand that the Trinitron system simplified set up, produced a much sharper picture and made CRT TVs so much more reliable...
Woooow colour look so vibrant !!!
As always Doug... another great video. Thank you...
+drh4683; I'm just your average tech geek, and the technology of old TVs - in particular, the colour systems used, such as field sequential are fascinating. I came along in time sheet this type of set, but I DO remember visiting my grandparents who had a similar set (one thing which I think is sad in many ways is the use/bed of a repair person. Now, is just built-in obsolescence, which is not a good thing for the planet (but IS fit a businesses bottom line). Though I'm not fully understanding everything you've doing, it's really interesting.
On a side note - and I DON'T mean this men-ly, but, as a compliment, I'm watching this in a very small screen, and you remind me of the late, great John Candy. You've a good demeanour, on-camera. Again, thanks.
A true master of your craft! Thanks for sharing
This was very informative, thanks for sharing your knowledge, I am glad to be learning about things like this!
Goodness gracious! My parents had a TV just like this one--our first color set. Wow...
This brings back fond memories! Be careful around that high voltage. I've gotten some nasty shocks from flyback transformers.
This was super interesting to witness and I'm happy there are people out there who still understand how to maintain this technology!
I rue the day CRTs no longer exist Q_Q
Awesome other than listening to the breathing of the camera man. :)
Love the 60s elevator music. I feel like I'm buying clothes at J.C. Penney's in 1967.
This was awesome to see how it's done. Now I know why my Dad would hit me when I played around with the settings, lol. Not to sound like a creep, but glad to see your face again, lol.
Very interesting as always! Great video!
Legend has it that TV still works
I'm glad you know what you're doing. I'd be terrified of the voltages.
I would imagine that Nordmende doing this back in the day would had done purity and convergence adjustments in a dark room with special optical instruments to ensure the absolute best possible color reproduction.
Some of the newer disc players come with a feature that allows you to use grey instead of black when watching anamorphic movies. It prevents burn in because it's less contrast.
Wonderful to find videos like this one. Technicians with the knowledge, skills and equipment to perform such work are scarce.
One question, though:
Why don't you position a mirror in front of the screen while making adjustments from the back of the set?
Is there a reason that the sound on the TV is on? We really don't need to hear all that buzzing. Good video, I cut my teeth on the old tube sets, and work on vintage video equipment on my channel too.
I think the sounds from the flyback transformer harmonizing.
The sound adds to the charm, especially when he's working on the convergence. It conveys some of the mystery of early TV.
Another great video, Doug.
Nothing beats these tube sets, this is one technology we cant improve on, plasma is next best, id put LCD right at the bottom.
I would put LED and LCD at the bottom at the same time. I just got a similar TV from drh4683 that looks like this one but the legs are a little different, but it seems to produce a well defined picture and it is much better than the piece of junk flat screen that went out on me after a few weeks.
Yall can't be serious. Bulky low resolution tube sets better then hd tvs??
Fantastic work!
How much life is left in the CRT after a rejuvenation? Set has a very nice picture.
Excellent video, Doug :)
the sounds are fantastic
Amazing video. Thank you for doing this.
This is really cool. Good job.
Any relation to Drew Carry?
Thank you so much! Great stuff indeed!
Enjoyed reading your comments about TV technology, the old 1960s dinosaurs versus the new HD sets. It makes me laugh reading these sentimental comments about how much better the older sets are than today's technology. I don't think these people realize how expensive and out of reach color TVs were to average people in the 1960s. Both my parents were teachers and we didn't own a color set until 1972. Not only are today's sets superior, they're a lot more affordable to the average person.
another great video! Keep them coming:)
Interesting.
But you could have turned down the volume on that TV during this video (or disconnected the speaker) to avoid hearing the annoying "screaming" and "hum" of the video signal bleeding into the audio amp section ! Geez.
On the newer sets I turn down the color for a B&W picture then adjust gray scale, convergence, contrast and brightness.
How at your age do you know what you know, the reason I ask this question is because is I worked at a Shop that was a Zenith warranty center you know what you are talking about , I’ve Evan learned a lot of this from you channel. Do a video on how you learned what you know because it’s spot on.
Remember, straightening out the blue horizontal convergence lines involves using the static convergence. Straighten the blue, ignoring the static convergence.
stuff i learned in high school. we could take classes at james rumsey vol-tech in high school. high school electronics. i did these things to tvs before, @1978.
I was able to filter out the annoying TV whine using the Realtek HD Audio Manager from the Windows desktop tray in the lower left hand corner. Use the graphic equalizer and bring down the middle ranges. It's worth the trouble for the information on this video. Arrange the slide bars so it resembles a "V"
20:31: It’s interesting when you turn it off it’s three colors blip out at once but the remaining colors comeback in the middle as it blows away like the wind
I have a 1984 Trinitron where there top right corner ever so slightly is blue. do you know why this may be and how I can correct it? thanks
great demonstration.
I used to do that when I was a kid.
But so many of those TVs had bad picture tubes and I didn't have a rejuvinator.
I have several now.
So cool!!
Always enjoy your videos. Is it possible for you to make a video on how analog TV work. Basic theory. Do you repair modern HD TV as well?
Nice instructional video. Thanks for doing this.
Ah the Sencore CR-7000. I envy you... :)
