Zenith Color TV first start up

- I replaced a tube In my Zenith color round TV. Mind you I don’t have any previous knowledge of tube TV’s and this is my first. I intend to use this TV as a learning experiences for a way to further my knowledge in analog technology. Any advice would be appreciated and for those who may get upset at my lack of knowledge and take solace in knowing That you can’t start with knowing, you have to learn, and this is my way I wish to.
Man I love your setup - vintage roundie, records and stereo speakers everywhere.
I do, on a purely freelance basis, what you demonstrated in this video, albeit with patterns on DVD and BluRay. Today it's called display 'calibration', but I think a better term would be alignment, as it is akin to wheel alignment - for your TV! 😉
If you like the vintage stuff because the channel is more for my Twitch videos, you can check out my Instagram @GVComputing
@@timtheenchanter0476 Thanks!
Thanks for showing your tester . I have one too but I didn't understand how to use it now , I just have to round up some slides .
I remember old TV's took about a MINUTE to even think about coming on!
👍Agreed. I remember those days. My parents had a Setchell Carlson from the late 50s. It took about a minute to come up. But, from my standpoint, it was the best black and white TV in the house.
"Thankfully" new smart TVs have their interfaces so damn LAGGY that it can take a minute of powering on from standby and skipping past menus and ads as well!
@@neoqueto 👍I’ve seen a few like that depending on brand. My TVs aren’t that bad unless it was unplugged or interrupted by a general power failure.
when you switched one of those you could be sure they worked, now tvs do anything but never in a reliable way, sometimes they work, sometimes they refuse.
I'm hoping you are aware that these old tube CRT's can and do generate extremely high voltages at the plates and caps, high enough to be deadly. Learning is great and yes, everyone has to start somewhere, but those old TV Repairmen went through highly structured training programs under mentorship of senior technicians, mainly manufacturer specific models. None of them (that survived) just sat down and trained themselves. Please be very careful. Assume the line is hot. Assume the plates are live. Assume the caps are charged. ALWAYS!
I have a degree in electrical engineering and mechatronics. I am very familiar with safety processes. I’ve been repairing vintage tech since I was about 12 and have had many people help me learn. I will be careful.
@@timtheenchanter0476How can we determine the truth behind this without the essential in depth duel of polyvariable?
*polyvariable calculus
yt algorithm knows what i like... i am too afraid to do it myself because i know it is dangerous (for non-technician like me) but watching when someone does such a cool thing is extremely... addictive.
Don't worry about high voltage just ground the picture tube anode in case it has some residual voltage . If you need any help or advice just ask me . I used to fix these old roundy color TVs and that is how I paid for college .

Flashback 😮
This tv looks to be at least 60 years old. Must have been a pain in the butt to get it working, and im glad you figured it out.
Thanks!
It would be wise to replace all paper capacitors in the set. Seems that the electrolytics are fine, but at that age, those are risky, too. You likely won't have a proper stable picture until the paper caps are replaced, and you risk damage since leaky capacitors throw off grid bias.
I would love to but I am having a hard time finding any good guidance on how to do so. If you know of any good sources please let me know.
I believe at this point Zenith was using those orange Spraigh orange caps. This TV looks to be 1966.
@@edp9821 Were they film by then? I've seen maroon Spragues that were film, which, of course, is good quality.

@@td3993 orange gum drops they were called.
An acquisition system, cool. This uses an UV phosphor CRT, much cooler...
Fantastico!!!
increible, but true.
Wow! That’s an old video test generator.
That's very cool man. I didn't know that was a thing. What was that for?
¿Cómo se llama el aparato donde colocas las cartas de ajuste?
Can you fix my zenith tv? it got lines on top and there's a dead spot forming on top
I hope this TV has been recapped. An exploding electrolytic is not fun.
It has, I refurbish vintage tech mostly TVs
I’ve been collecting vintage TVs for over 30 years now and have yet to have an electrolytic explode. Heck some of these tube color sets were still in use well into the 80s and 90s. The more use these sets had the better the electrolytics held up over time vs a set that hasn’t been turned on since say the 1950s.
